Lotion Look for personal care products
without the word "fragrance" in the ingredient list to cut down on your exposure to chemicals. This catchall term can mask the presence of a slew of toxins. Don't trust product claims of being unscented, warns the Environmental Working Group, as fragrances may be used to create the unscented effect. You actually have to scan the ingredients to confirm that the word "fragrance" does not appear.






Fetus in the womb by da Vinci
The old view was that the "placental barrier" protected the fetus from contaminants in the mother's body. Recent research has shown this to be false. For instance, ten of ten newborns whose umbilical cord blood was tested on their day of birth as part of the Human Toxome Project were found to be contaminated with scores of chemicals, including many "linked to brain and nervous system toxicity, cancer, and birth defects and developmental delays."

(The drawing, by the way, is an "old view" by Leonardo da Vinci.)






Unsafe at any level. Toxicologists are fond of saying, the dose makes the poison," meaning that toxic substances are only toxic above a certain level. This explains their method of safety testing, which is to begin at the high end of the dose spectrum and work their way down until they find a dose that seems safe. But such thresholds may not exist with endocrine disruptors, which can have effects at unimaginably small doses, while sometimes having different or no effects at higher levels. Environmental health scientists are therefore looking for new testing methodologies that take these different patterns into account.

Pollution in People

For years, I thought I could keep my
body free of dangerous chemicals by taking just a couple of simple precautions -- using natural cleansers and buying organic food. Wrong.

Body burden Biomonitoring tests to check for chemicals in people always find them. It doesn't matter whether the people are old, young, newborn or even fetal, nor what their history is. Contamination is always found. It is therefore a virtual certainty that if I were to be tested, I would learn I was contaminated, too. Not to cause panic, but so would you.

This pollution of our bodies is thought by many scientists to be universal today. It goes by the name of body burden.

Where do the chemicals come from? They are used in a seemingly endless array of industrial applications and consumer products, including baby toys, air freshener, laundry detergent, shampoo, nail polish, food containers, rugs and furniture, to name a few.

And how do they get into our bodies? Through our food, tap and bottled water, indoor and outdoor air and many of the things we touch or put on our skin. Babies get them in the womb from their mothers. Hence, the phenomenon of infants starting life with chemicals already in their systems.

Given how ubiquitous chemicals are, the question is not really how they get into us, but whether there is any way to keep them out. I will get back to that.

Let's first talk about whether and how the chemicals might harm us. The chemical industry predictably claims they are safe. In reality, next to nothing is known about the vast majority of them. That's because our laws allow chemicals to go on the market without prior safety testing.

But we do know quite a bit about a few chemicals, and what we know is not reassuring. For instance:

  • Phthalates have been linked to problems with reproductive system development in baby boys and to insulin resistance and obesity in adult men. They are used in a wide variety of cosmetic products, such as moisturizers, nail polish and baby powder; cleaning products; plastic food wraps; and toys, especially those made with PVC plastic. Other uses include medical equipment and building supplies.
  • Bisphenol A (also known as BPA) has been linked to breast and prostate cancer, reproductive problems, diabetes and alteration of brain chemistry and behavioral changes. It is used in many household products, including plastic baby bottles, hard plastic sports bottles and metal food cans, which are often lined with plastic to prevent a metallic taste in food.
  • PCBs, which were formerly used as electrical insulators, among other things, have been found to affect the immune, reproductive, nervous and endocrine systems. They are also considered a probable carcinogen. Though their production in the U.S. was banned in 1979, these long-lasting chemicals continue to circulate in the environment and in the food chain. New releases also occur when old equipment made with PCBs is damaged or improperly disposed of.
  • Dioxins, a byproduct of the manufacture and burning of chlorine products, can affect the cardiovascular, respiratory, immune, reproductive, nervous and endocrine systems and cause cancer.

Other classes of chemicals shown to be toxic include PBDEs (used as flame retardants) and PFCs (used to repel water, stains and grease).

All the chemicals listed above are endocrine disruptors, meaning that they interfere with the workings of the endocrine -- or hormone -- system. Hormones are our bodies' chemical messengers. They tell cells to start or stop carrying out key functions at the proper time. While key to basic body functioning throughout our lives, they are particularly important to fetal development. During the nine months in which a baby takes shape, an exquisitely timed orchestra of these chemical signals ensures that the baby's body develops as it should. Any tampering with the type or timing of the signals can have tragic consequences, from cancers that emerge later in life to missing body parts. They can also affect the brain and behavior.

The years directly leading up to puberty, when hormones again play a major role in body development, may be another time when people are particularly sensitive to endocrine-disrupting chemicals.

So, how can you protect yourself, your children and your children-to-be?

Unfortunately, moving somewhere remote is not, in itself, an answer. Many chemicals are highly mobile and resistant to breakdown. Over the last few decades, they have spread on wind and water currents to every corner of the globe, including the most pristine places.

However, your personal practices can make a difference in your LEVEL of exposure, not just to endocrine disruptors but to other toxins that humans are spewing out into the environment. These steps, in particular, can help:

At the same time as you take these steps in your own life, keep in mind that the real solutions to body burden, like other forms of pollution, are societal not individual. Without government regulation, safety from chemicals is a losing battle.

THE FUTURE OF DRINKING WATER

Could this be ebb tide for the bottled water craze?

For years, NRDC has been crying in the wilderness that bottled water is not any safer than tap -- and in many cases actually is tap. Though frequently cited, these findings, based on a four-year study published in 1999, never seeped into the public consciousness until now.

What's in the water? Suddenly, everyone seems to have discovered that tap water can be perfectly drinkable --and that bottled water has problems of its own. In a bit of reverse chic, the stuff you can get virtually for free is now in. Big city mayors are pushing it, high-profile restaurateurs are offering nothing but, and even the New York Times editorial board has seen fit to recommend it.

For many of the new converts, tap water's chief advantage is that it doesn't leave a flood of non-biodegradable and rarely recycled containers in its wake -- nor require the manufacture of said containers from non-renewable petroleum in the first place. For others, it's the fact that tap water usually flows to us through energy-efficient infrastructure. No trucks or ships required.

Who could argue with either point? Major population centers are already drained of landfill space. They don't need the additional strain placed by millions of plastic water bottles. Nor can any of us tolerate the unnecessary contribution to global warming that transporting the water to market makes -- whether all the way from Fiji or just across the state.

But the main reason to prefer tap water, in the end, may, ironically, be safety -- not because tap water is inherently purer (it's not), but because it is better regulated.

Now, don't go to sleep on me just because I used the "R" word. Regulations are the teeth of the law -- and tap water's teeth are stronger than bottled water's, translating to higher safety standards and better monitoring. That doesn't mean they are tough enough, and they do leave a wide range of contaminants uncovered (from rocket fuel to the gasoline additive MTBE), but they are nevertheless the tougher of the two, and better enforced besides.

Tap water is also regulated more consistently. Environmental Protection Agency rules apply to every public water system in the nation. In contrast, bottled water is governed by Food and Drug Administration rules when transported across state lines and otherwise by individual states.

One particular strength of tap water regulations is that they guarantee the consumer's "right to know" what's in his or her water. Utilities must issue annual "Water Quality Reports" -- also called "Consumer Confidence Reports" -- identifying the source of the water and contaminants found in it. FDA regulations for bottled water offer nothing comparable. False claims on labels are barred, but there is no requirement that contaminants within so-called safe limits be listed. You can ask bottled water companies for the information -- and by all means do if you drink it -- but recognize that they are under no obligation to tell.

A guaranteed "right to know" means more than you might think. Say there was arsenic in your tap or bottled water, but it was "only" 9 parts per billion (ppb). Arsenic is considered unsafe at any level, having been linked to cancer and other health problems. Yet both the EPA and FDA, in a bow to industry, which wants to keep water treatment costs down, allow up to 10 ppb. The bottled water label would not have to mention the arsenic (and might even call the water pure!). But the Water Quality Report from the utility would have to list it. Armed with that information, a savvy consumer could then get a filter to screen out the poison.

Whoa, did I say there could be arsenic in your tap water? Yes, I did. In your bottled water, too? Yes. And arsenic isn't the only scary thing -- in either.

So, if that's true, why am I pushing tap? Because the tap water in most places is still pretty good (amazing in some places), bottled water is no better and abandoning the public system will only serve to make tap water worse. Should that happen, the poor will be left with undrinkable water, while the well-off pay a premium for purity. Whether the rich will be able to find it is another matter.

If you are concerned about the quality of your tap water, here's what to do:

1) Ask your utility for a Water Quality Report and see if your fears are founded.

2) Consider filtering your water to address any problems you may have uncovered. Filters can help with water that tastes bad, too.

3) If your water fails to meet safety standards and you or a member of your household is very young, old, pregnant or living with chronic illness or a weakened immune system, consult your doctor about what to do. In some cases, bottled water may be the best alternative if it is from a source that is known to be good.

And please support local measures to protect your watershed, modernize infrastructure and upgrade drinking water treatment. They are the keys to clean, affordable drinking water for all.

Brushing teeth
The fluoride debate: Is it good to add fluoride to tap water (because it strengthens teeth) or bad (because it can cause health problems when too much is ingested)? Personally, I think some people may already be getting as much as they can take of this potentially toxic substance from toothpaste, naturally occurring fluoride in the water and other sources. But this is too big a topic to discuss here. You should just know that if your tap water is fluoridated and you want to get the fluoride out, there are filters that do the trick.

The truth is that some of these waters (Aquafina and Dasani) come from the same sources as tap.

Bill to Restore Clean Water Act Introduced
Legislation Would Secure Future Protection

Washington, DC (May 22, 2007) – Legislation designed to return crucial Clean Water Act protections to our nation’s bodies of water was introduced today in the U.S. House of Representatives. The bill, called the Clean Water Restoration Act of 2007, was introduced by Representatives James Oberstar (D-Minn.), John Dingell (D-Mich.), and Vernon Ehlers (R-Mich), along with a bipartisan group of more than 150 co-sponsors.
 
NRDC Clean Water Project Senior Attorney Jon Devine issued the following statement regarding the legislation:
 
“We commend the introduction of this important bill and hope Congress will act quickly and decisively in passing it. 
 
“For decades, the Clean Water Act has protected America’s water resources from industrial pollution, oil spills, sewage, and outright destruction. Recent interpretations of the law have placed many of the nation’s important water bodies in legal limbo, allowing polluters to discharge into water resources across the country without complying with the Clean Water Act’s intended safeguards. 
 
“This legislation will end this uncertainty and ensure that all of America’s water resources remain protected for future generations.”

Restoring America’s Clean Water Legacy

The 110th Congress Must Pass Legislation to Restore the Scope of the Clean Water Act

From the small stream your kids wade in to the marsh where you set up your duck blind, America’s water resources are an invaluable part of our nation and our economy. The creeks, brooks, and streams that make up over half the river miles in the continental United States contribute to the drinking water of roughly 111 million people. Wetlands purify water, reduce the risk of flooding, and provide important wildlife habitat. But the law that has long protected our lakes, rivers, streams and wetlands from unregulated pollution, filling and destruction—the Clean Water Act—has been under assault in recent years. Congress must act to stop the rollback of protections that keep our water clean.

Since the passage of the Clean Water Act (CWA) in 1972, we have made great progress in cleaning up our nation’s waters. While much remains to be done, the law has been the bedrock of our improvements.

That’s why it’s so troubling that these protections have been rolled back in recent years, and why it’s crucial that Congress act to stop the attacks. Legislation that restores the scope of the CWA is the best and surest solution for restoring our clean water legacy.

A History of Clean Water Act Protections

The Act safeguards all of the “waters of the United States,” with several basic protections built into the law – the Act’s prohibition on unpermitted point source discharges, the oil spill prevention program, and the impaired waters cleanup program, to name a few. In expanding the law in 1972 to the “waters of the United States,” Congress made clear that it passed the law with the intent that it “be given the broadest possible constitutional interpretation.” The EPA and Army Corps regulations implementing the law have for decades reflected this intent. They cover, among other things, tributaries of various waters, adjacent wetlands, and intrastate waters with linkages to interstate commerce.

These rules had been upheld by the vast majority of courts that examined them, including the Supreme Court. But in 2001, the Court – in a case called Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers (or “SWANCC”)—held that non-navigable, intrastate waters are not protected by the CWA solely because they are used by migratory birds.

Unfortunately, SWANCC gave polluters an opening to pressure the EPA and the Corps to consider changing their rules. In response to this scheme, the agencies were inundated by more than 130,000 commenters, including dozens of states, overwhelmingly demanding that the rules be kept intact.

This public outcry succeeded when the agencies cancelled the rulemaking process. However, EPA and the Corps kept in place a policy document directing the agencies’ field staff to stop applying CWA protections to many waters unless they first receive permission from headquarters in Washington, D.C. Thousands of waters have been declared unprotected since the policy took effect, and some 20 million acres of wetlands are at risk nationwide because of the policy.

Polluters also seized on SWANCC in the courts, saying that it the law was intended to protect  only waters that are actually navigable. Though this claim was largely rejected, those opposed to CWA protections were able to convince the Supreme Court to hear another case—Rapanos v. U.S.—which examined whether the law protects non-navigable tributaries and their adjacent wetlands.

The result was a messy split decision: The Court did not invalidate the existing rules, but the various opinions suggested different tests. Justice Kennedy would require the agencies to show a physical, biological, or chemical linkage—a “significant nexus”—between a water body and an actually navigable one to protect it. Four other justices would require most water bodies to be continuously flowing or standing, and would require wetlands to have a continuous surface connection to such waters.

Current Law Is in Disarray 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 The 2003 policy directive remains in place, despite criticism by the Government Accountability Office and a strong bipartisan May 2006 vote in the House to block the implementation of the directive. Under this policy, waters continue to be declared unprotected, and 20 million acres of wetlands are at risk of pollution or destruction.

 Polluters are urging the agencies to write off whole categories of water bodies because of the rulings, even though there was no such directive from the Court and even though as a matter of science, tributaries, and wetlands surely have a “significant nexus” to the traditional navigable waters in their watersheds.

 The agencies are overdue in issuing promised guidance on Rapanos. Even if the guidance comes out soon and rejects the polluters’ push, it will surely depend on the “significant nexus” concept, which will likely be difficult, time consuming, and expensive to implement in practice.

 Numerous suits have been filed challenging CWA protections over tributaries and wetlands, and the court decisions thus far have dealt with the new decision inconsistently. One court even held that the law didn’t apply to an oil spill into a small tributary.

 An industry funded legal foundation has filed a legal petition arguing that Rapanos generally requires -the agencies to deny protection to waters unless they are continuously flowing or standing, and only protect those wetlands “indistinguishable” from other waters, based on the opinion of four Supreme Court justices that was rejected by a majority of the Court.

Legislation Is the Best and Surest Solution

 A statutory fix will prevent the political agency heads from using the court decision as an excuse to exclude certain kinds of waters from protection at the urging of polluters.

 Four Supreme Court Justices support a radical rewriting of the law, one which would exclude approximately 2 million miles of streams from protection, along with countless acres of wetlands. Specifying the waters that Congress means to protect will guard against judicial over-reaching.

 Not restoring the law risks years of litigation and inconsistent decisions. More importantly, it means that numerous waters will be destroyed or polluted.

Designing a Legislative Solution

To restore the traditional scope of protection intended by Congress and to achieve the goal of restoring and maintaining the chemical, physical, and biological integrity of the nation’s waters, legislation must:

 Define protected “waters of the United States” based on the decades-old definition in Corps and EPA regulations;

 Delete the word “navigable” from the Act to clarify that the Clean Water Act is principally intended to protect the nation’s waters from pollution, and not just maintain navigability;

 Explain the basis for Congress’s assertion of constitutional authority over the nation’s waters, as defined in the Act, including smaller water bodies and so-called “isolated” waters.

An example of legislation that would achieve these goals was introduced in the 109th Congress—the Clean Water Authority Restoration Act (H.R. 1356/S. 912). When an equivalent bill is introduced in this Congress, please support it.

Consumer Guide to Water Filters
How to find the right water filter for your home.
[En Español]

The water coming out of your faucet may not be as clean as it should be. NRDC is working toward the day when all Americans can drink and shower in tap water without worry, but if you have immediate concerns about the water in your home, an independently certified water filter can be a good temporary fix for your kitchen faucet. Some filters aim to produce clearer, better-tasting water, while others work to remove contaminants that could affect your health. This guide will help you determine what type of filter might be right for your home.


Find Out What's in Your Water

In many cities, healthy adults can drink tap water without cause for concern. However, pregnant women, young children, the elderly and people with compromised immune systems are particularly vulnerable to some contaminants in tap water. If you're shopping for a water filter, first find out what pollutants might be in your water. Check the NRDC report What's On Tap?, and ask your water utility (the company that sends you your water bill) for a copy of their annual water quality report. ("Making Sense of Your Right to Know Report" can help you decipher reports issued by your water utility.) NRDC recommends that you test your tap water for lead contamination, particularly if you have young kids, are pregnant, or thinking about becoming pregnant, since lead is especially dangerous and levels can vary enormously from house to house. A lead test costs about $25 (see, for example, University of North Carolina's low-cost testing information). Once you know what's in your water, you can find a filter that's geared toward getting rid of the specific pollutants, if any, that may be present.


Select the Right Filter

Household water filters generally fall into one of two categories: point-of-entry units, which treat water before it gets distributed throughout the house; and point-of-use units, which include countertop filters (e.g. filter pitchers), faucet filters, and under-the-sink units. Some filters use more than one kind of filtration technology. As a general rule, look for filters labeled as meeting NSF/ANSI standard 53 and that are certified to remove the contaminant(s) of concern in your water. While the NSF certification program is not flawless, it does provide some assurance that at least some claims made by the manufacturer have been verified. NSF-certified filters have been independently tested to show that they can reduce levels of certain pollutants under specified conditions. Those that meet standard 53 are geared toward treating water for health, not just for aesthetic qualities.

For many people, an activated carbon filter bearing NSF Standard 53 certification will filter out most pollutants of concern. But if you've got perchlorate, a rocket fuel ingredient, in your water, for example, a simple countertop filter won't do the job. The list below will you help you determine what type of filter will work best for you. Once you've got a general idea, visit NSF International's drinking water treatment units online product database.


  • Activated Carbon Filter

    How it works : Positively charged and highly absorbent carbon in the filter attracts and traps many impurities.

    Used in : Countertop, faucet filters and under-the-sink units.

    Gets rid of : Bad tastes and odors, including chlorine. Standard 53-certified filters also can substantially reduce many hazardous contaminants, including heavy metals such as copper, lead and mercury; disinfection byproducts; parasites such as Giardia and Cryptosporidium ; pesticides; radon; and volatile organic chemicals such as methyl-tert-butyl ether (MTBE), dichlorobenzene and trichloroethylene (TCE).

     

  • Cation Exchange Softener

    How it works : "Softens" hard water by trading minerals with a strong positive charge for one with less of a charge.

    Used in : Whole-house, point-of-entry units.

    Gets rid of: Calcium and magnesium, which form mineral deposits in plumbing and fixtures, as well as barium and some other ions that can create health hazards.

     

  • Distiller

    How it works : Boils water and recondenses the purified steam.

    Used in : Countertop or whole house point-of-entry units; can be combined with a carbon filter.

    Gets rid of : Heavy metals such as cadmium, chromium, copper, lead and mercury, as well as arsenic, barium, fluoride, selenium and sodium.

     

  • Reverse Osmosis

    How it works: A semipermeable membrane separates impurities from water. (Note: This filtration technique wastes a substantial amount of water during the treatment process.)

    Used in: Under-the-sink units; often in combination with a carbon filter or UV disinfection unit.

    Gets rid of: Most contaminants, including certain parasites such as Cryptosporidium and Giardia; heavy metals such as cadmium, copper, lead and mercury; and other pollutants, including arsenic, barium, nitrate/nitrite, perchlorate and selenium.

     

  • Ultraviolet Disinfection

    How it works: Ultraviolet light kills bacteria and other microorganisms.

    Used in: Under-the-sink units, often in combination with a carbon filter and sediment screen.

    Gets rid of : Bacteria and parasites; class A systems protect against harmful bacteria and viruses, including Cryptosporidium and Giardia , while class B systems are designed to make non-disease-causing bacteria inactive.


Maintain Your Filter Properly

No filter will give you good performance over the long term unless it receives regular maintenance. As contaminants build up, a filter can not only become less effective, but actually can make your water worse, by starting to release harmful bacteria or chemicals back into your filtered water. To keep your filter working properly, follow the manufacturer's maintenance directions. Some filters only require a cartridge change, while others are better maintained by a certified professional. Many filter distributors offer maintenance and service contracts for their products. Before buying any water treatment system, compare not only filter prices, but also operating and maintenance costs for the different units. To find a dealer in your area, see the Water Quality Association's online listings.

What's on Tap?
Grading Drinking Water in U.S. Cities


This June 2003 NRDC study of drinking water quality in 19 U.S. cities finds that pollution and deteriorating, out-of-date plumbing are sometimes delivering drinking water that might pose health risks to some residents -- and unless steps are taken now, tap water will get worse. The report issues grades to each municipal water system studied in three problem areas -- water quality and compliance, source water protection, and right-to-know compliance -- and outlines a plan for protecting the nation's drinking water supply.

Study Finds Safety of Drinking Water in U.S. Cities at Risk
NRDC reports on the drinking water systems of 19 cities and finds that pollution, old pipes and outdated treatment threaten tap water quality.

How's the Water?
In many places there's a lot of work to be done:

Tap water in many cities might pose a health risk to some residents
Sometimes cities aren't truthful about what's in the water
The sources of tap water often aren't adequately protected

Click here for a sampling of the "special ingredients" found in urban America's tap water.
See a map of the grades received by the 19 cities NRDC studied.

We often take the purity of our tap water for granted -- and we shouldn't. NRDC's What's on Tap?, a carefully researched, documented and peer-reviewed study of the drinking water systems of 19 U.S. cities, found that pollution and deteriorating, out-of-date plumbing are sometimes delivering drinking water that might pose health risks to some residents.

Many cities around the country rely on pre-World War I-era water delivery systems and treatment technology. Aging pipes can break, leach contaminants into the water they carry and breed bacteria -- all potential prescriptions for illness. And old-fashioned water treatment -- built to filter out particles in the water and kill some parasites and bacteria -- generally fails to remove 21st-century contaminants like pesticides, industrial chemicals and arsenic.

What's on Tap? found one overarching truth: If steps are not taken now, our drinking water will get worse.

Recent actions by the Bush administration are making the problem worse instead of better. Seemingly more concerned about protecting corporate polluters than protecting public health, the administration is campaigning to hobble existing laws, thwart efforts to strengthen current pollution standards and cut funds for programs that protect tap water.

Government -- whether city, state or federal -- should be doing all it can to ensure that citizens get clean, safe drinking water every time they turn on a faucet or stop at a public water fountain. And an informed, involved citizenry is the key to the process; it's our hope that What's on Tap? will encourage all Americans to look into the quality of their city's water supply, and to demand that our elected officials do what's necessary to provide safe tap water.

What's on Tap? issues grades for each studied city in three areas: water quality, right-to-know reports, and source water protection.

 

Water Quality and Compliance

The Bottom Line: Water Quality and Compliance

Good drinking water depends on cities getting three things right:

  • Lakes, streams, reservoirs and wells must be protected from pollution
  • Pipes must be sound and well-maintained
  • Modern treatment facilities are a must

If just one of those three factors goes awry, water quality will suffer. For example, these four cities have fair-to-substandard drinking water:

  • Atlanta, which maintains its distribution system poorly
  • Albuquerque and San Francisco, which have poor treatment systems
  • Fresno, which has no real source water protection

So what does all this mean in terms of what's actually in your water glass? If your city has a water quality problem, your tap water may at times carry a worrisome collection of contaminants.

Tap water can contain a vast array of contaminants, but a handful showed up repeatedly in the water of the cities we studied:

  • Lead, which enters drinking water supplies from the corrosion of pipes and plumbing fixtures and can cause brain damage in infants and children
  • Pathogens (germs) that can make people sick, especially those with weakened immune systems, the frail elderly and the very young
  • By-products of chlorine treatment such as trihalomethanes and haloacetic acids, which may cause cancer and reproductive problems
  • Arsenic, radon, the rocket fuel perchlorate and other carcinogens or otherwise toxic chemicals

Contaminants like these get into our water from many different sources. A few examples: runoff from sewage systems that overflow after a heavy storm; runoff from contaminant-laden sites like roads, pesticide and fertilizer-rich farms and lawns, and mining sites; wastes from huge animal feedlots; and industrial pollution that leaches into groundwater or is released into surface water.

A high level of any of these contaminants in your water represents a failure of your city's "water treatment train" -- a series of steps your water is put through to filter and disinfect it before it is delivered to your tap. By extension, it also represents a failure by your government -- local, state and federal -- to protect your water supply and ensure that pure, safe and good-tasting water is supplied to your home.

NRDC's study found that relatively few cities are in outright violation of national standards for contamination of drinking water, but this is more a result of weak standards than it is of low contaminant levels. For example, cancer-causing arsenic is currently present in the drinking water of 22 million Americans at average levels of 5 ppb, well below a new EPA standard for arsenic of 10 ppb that will go into effect in 2006. Yet scientists now know that there is no safe level of arsenic in drinking water. (The EPA found that a standard of 3 ppb would have been feasible, but industry lobbying and concerns over treatment costs prevailed over public safety.) Many cities failed to meet the EPA's "level of concern" for various contaminants that are not yet regulated.

Our study yielded another broad truth about the nation's drinking water "treatment trains": many cities show an increase in the frequency of periodic spikes in contaminant levels, indicating that the World War I-era plumbing and water treatment facilities still widely employed may be inadequate to handle contaminant spills or even the basic daily contaminant loads produced by our heavily industrialized, densely populated cities. And spikes above the EPA's standards generally don't trigger a violation; usually only an average level over the standard is considered a violation.

The bottom line is this: the tap water in some cities might pose health risks to vulnerable consumers -- people who have serious immune system problems, pregnant women, parents of infants, those with chronic illnesses and the elderly should consult with their health care providers about the safety of tap water. (See this fact sheet from the Campaign for Safe and Affordable Drinking Water for more information on protecting the vulnerable.) And our nation must make a major commitment to upgrading and modernizing water systems and protection of drinking water sources.

Right-to-Know Reports

Your Right to Know What's in Your Tap Water

The first question that one would logically ask on reading the above is, "How do I find out what's in my water glass?" And according to U.S. law, every citizen is entitled to a straight answer. Every city is required to publish reports about the safety and quality of its drinking water system.

The problem, as NRDC found, is that while some cities do a good job with their right-to-know reports, others publish information that is incomplete or misleading:

  • Reports from Atlanta, Boston, Fresno, Houston, Newark, Phoenix, Seattle and Washington, D.C. included false, unqualified or misleading claims, or buried crucial information about problems deep in their reports;
  • Reports from Newark, New Orleans and Phoenix included incorrect or misleading data -- or omitted it entirely;
  • Nearly all cities in the study failed to report on health effects of most contaminants found in their water;
  • Most of the cities studied failed to translate the reports into languages spoken by a large minority in their community.

These right-to-know reports hold enormous promise. In addition to informing citizens about the state of their city's water system, they can also build support for investment and encourage citizens to participate in fixing local problems. They are so important that NRDC decided to grade each city's right-to-know reports as part of this study; we've also included a set of recommendations that cities might adopt in setting goals for their right-to-know publications.

Source Water Protection

Protecting the Source

The first line of defense in ensuring the safety and quality of drinking water is to ensure that water sources -- lakes, rivers, streams and aquifers (porous underground formations that hold water) -- are protected from pollution. And as indicated above, there are many ways that contaminants get into source water, among them:

  • Municipal sewage
  • Polluted runoff from stormwater or snowmelt in urban and suburban areas
  • Pesticides and fertilizers from agricultural fields
  • Animal waste from feedlots and farms
  • Industrial pollution from factories
  • Mining waste
  • Hazardous waste sites
  • Spills and leaks of petroleum products and industrial chemicals
  • "Natural" contamination such as arsenic or radon that occurs in water as a result of leaching or release of the contaminant from rock

To keep such contaminants out of tap water, a city's first step is identifying where pollution is coming from. Once these sources are known, the water utility, city planners and citizens of a municipality must work together to figure out how to reduce the threat of contamination. Land purchases often prove useful, allowing the water utility to establish a pollution-free zone around source waters. Utilities may also ban boating and other recreational activities on these waters, push for improved pollution controls, or protect wetlands (which replenish and purify source waters).

Some cities are doing a fine job of protecting their drinking water supply. Seattle is doing an excellent job of protecting source water; Boston, San Francisco and Denver also get high marks. But many other cities have a long way to go:

  • Albuquerque's groundwater is becoming seriously depleted; Fresno's groundwater is highly susceptible to contamination;
  • In Atlanta, Chicago, Detroit, Houston, Los Angeles, New Orleans, Newark, Philadelphia, Phoenix, San Diego and Washington, D.C., source water is threatened by runoff and industrial or sewage contamination;
  • Water supplies in Baltimore, Fresno, Los Angeles, New Orleans, San Diego and several other cities are vulnerable to agricultural pollution containing nitrogen, pesticides or sediment;
  • Denver's source water faces an additional challenge from debris from wildfires and sediments from floods;
  • Manchester's problems apparently come from recreational boating activity in its reservoir.

An informed, involved public is a water utility's strongest ally in an effort to better protect its water supply. NRDC recommends that citizens urge legislators not to pull the plug on safe water supplies -- the Bush administration's broad assault on Clean Water Act protections should be stopped, and Congress should act to strengthen the laws and contaminant standards we have in place to protect the purity and safety of our drinking water.

1. Isn't bottled water safer than tap water?

No, not necessarily. NRDC conducted a four-year review of the bottled water industry and the safety standards that govern it, including a comparison of national bottled water rules with national tap water rules, and independent testing of over 1,000 bottles of water. Our conclusion is that there is no assurance that just because water comes out of a bottle it is any cleaner or safer than water from the tap. And in fact, an estimated 25 percent or more of bottled water is really just tap water in a bottle -- sometimes further treated, sometimes not.

 

2. Is bottled water actually unsafe?

Most bottled water appears to be safe. Of the bottles we tested, the majority proved to be high quality and relatively free of contaminants. The quality of some brands was spotty, however, and such products may pose a health risk, primarily for people with weakened immune systems (such as the frail elderly, some infants, transplant and cancer patients, or people with HIV/AIDS). About 22 percent of the brands we tested contained, in at least one sample, chemical contaminants at levels above strict state health limits. If consumed over a long period of time, some of these contaminants could cause cancer or other health problems.

 

3. Could the plastic in water bottles pose a health risk?

Recent research suggests that there could be cause for concern, and that the issue should be studied closely. Studies have shown that chemicals called phthalates, which are known to disrupt testosterone and other hormones, can leach into bottled water over time. One study found that water that had been stored for 10 weeks in plastic and in glass bottles contained phthalates, suggesting that the chemicals could be coming from the plastic cap or liner. Although there are regulatory standards limiting phthalates in tap water, there are no legal limits for phthalates in bottled water -- the bottled water industry waged a successful campaign opposing the FDA proposal to set a legal limit for these chemicals.

 

4. How can I find out where my bottled water comes from?

A few state bottled water programs (e.g., Massachusetts and New York) maintain lists of the sources of bottled water, but many do not. Try calling or writing the bottler to ask what the source is, or call the bottled water program in your state or the state in which the water was bottled to see if they have a record of the source (your state's health or agriculture department is most likely to run the bottled water program). If you choose to buy bottled water and are concerned about its safety, buy brands with a known protected source and ones that make readily available testing and treatment information that shows high water quality.

 

5. How can I determine if bottled water is really just tap water?

Often it's not easy. First, carefully check the bottle label and even the cap -- if it says "from a municipal source" or "from a community water system" this means it's derived from tap water. Again, you can call the bottler, or the bottled water program in your state or the state where it was packaged.

 

6. What actions can I take to improve bottled water safety?

Write to your members of Congress, the FDA, and your governor (see below for contact information) and urge them to adopt strict requirements for bottled water safety, labeling, and public disclosure. Specifically, point out to these officials that they should:

  • set strict limits for contaminants of concern in bottled water, including arsenic, heterotrophic-plate-count bacteria, E. coli and other parasites and pathogens, and synthetic organic chemicals such as "phthalates";
  • apply the rules to all bottled water whether carbonated or not and whether sold intrastate or interstate; and
  • require bottlers to display information on their labels about the levels of contaminants of concern found in the water, the water's exact source, how it's been treated, and whether it meets health criteria set by the Environmental Protection Agency and the Centers for Disease Control for killing parasites like cryptosporidium.

Members of Congress and governors should also pass legislation providing the resources for the FDA and state regulators to actually enforce the law.

To take further action, you can encourage your bottlers and the International Bottled Water Association (a trade organization that includes about 85 percent of water bottlers) to voluntarily make labeling disclosures such as those above.

How does drinking bottled water affect the environment?


In 2006, the equivalent of 2 billion half-liter bottles of water were shipped to U.S. ports, creating thousands of tons of global warming pollution and other air pollution. In New York City alone, the transportation of bottled water from western Europe released an estimated 3,800 tons of global warming pollution into the atmosphere. In California, 18 million gallons of bottled water were shipped in from Fiji in 2006, producing about 2,500 tons of global warming pollution.

And while the bottles come from far away, most of them end up close to home -- in a landfill. Most bottled water comes in recyclable PET plastic bottles, but only about 13 percent of the bottles we use get recycled. In 2005, 2 million tons of plastic water bottles ended up clogging landfills instead of getting recycled.

 

 

 

 

 

 

 

8. If I drink tap water should I use a filter and what types of filters are most effective?

The real long-term solution is to make tap water safe for everyone. However, if you know you have a tap water quality or taste problem, or want to take extra precautions, you should purchase filters certified by NSF International (800 NSF-MARK). These filters designate which contaminants they remove, and you can look for one that removes any contaminants of special concern such as cryptosporidium. Such certification is not necessarily a safety guarantee, but it is better than no certification at all. It is critically important that all filters be maintained and replaced at least as often as recommended by the manufacturer, or they might make the problem worse. See our guide to water filters for more information.

 

9. How can I obtain test results on my tap water?

Under new "right-to-know" provisions in the drinking water law, all tap water suppliers must provide annual water quality reports to their customers. To obtain a copy, call your water provider (the one that sends your water bills).

You also can test your water yourself, though this can be expensive. There are state-certified drinking water laboratories in virtually every state that can test your water. Call your state drinking water program or the EPA Safe Drinking Water Hotline (800 426-4791) for a list of contacts. Standard consumer test packages are available through large commercial labs at a relatively reasonable price.
