New Hazardous Chemicals Polluting U.S. Drinking Water

I missed PBS’ Frontline documentary, “Poisoned Waters,” which aired Tuesday evening. The program revealed that the U.S. Geological Survey (USGS) has found new chemical compounds—described by scientists as dangerous to human health—in drinking-water systems across the country. (You can view the full program online.)

“Poisoned Waters” shows that chemicals in our cosmetics, deodorants, prescription medications and household cleaners are finding their way into sewers, storm drains, waterways and drinking water—an environmental crisis that organic consumers have long recognized, but mainstream Americans may find surprising.

“The long-term, slow-motion risk is already being spelled out in large population studies,” explains Robert Lawrence, MD, a professor of environmental health sciences at Johns Hopkins University’s School of Public Health. These chemicals, known as endocrine disruptors, compromise normal physiological functioning.

“We can show that people with higher levels of some of these chemicals may have a higher incidence” of disease, as well as problems like lower sperm count, adds Linda Birnbaum, PhD, director of the National Institute of Environmental Health Sciences. “In most cases, we don’t know what the safe levels are.”

USGS tests of source waters for urban drinking-water systems have documented new contaminants coast to coast. Other scientists say these chemicals are causing fish kills, frogs with six legs, male fish carrying female eggs and other mutations—critical warning signs for humans.

Millions of people are being exposed to endocrine disruptors, Dr. Lawrence tells Frontline correspondent Hedrick Smith, “and we don’t know precisely how many of them are going to develop premature breast cancer, going to have problems with reproduction, going to have all kinds of congenital anomalies of the male genitalia—things that are happening at a broad low level so that they don’t raise the alarm in the general public.”

These emerging pollutants, coupled with well-known industrial contaminants like PCBs, lead, mercury and agricultural pollution from factory farms, have prevented the United States from making many of our waterways fishable and swimmable again.

“The environment has slipped off our radar screen because it’s not a hot crisis like the financial meltdown,” Smith concludes. “But pollution is a ticking time bomb. It’s a chronic cancer that is slowly eating away the natural resources that are vital to our very lives.”

    Allergic to the 21 st Century
    Many people thoughout the world have become ill from toxins in our environment. At least 15-20 % of the population is expeiriencing intolenaces to chemicals. Many have been left homeless trying to escape what is making them ill. We are the new homeless. http://www.chemicalsensitivityfoundation.org/

    We must educate ourselves and make changes to our lifestyles if we are to survive the 21 st century.

    There are many studies which indicate tap water contains pharmaceuticals. To be sure your tap water is safe you should filter your water. In addition to filter you can further improve your water with a alkaline water ionizers device. This device manipulates the molecular structure of water clusters to and raises the PH of the water. Scientific study has demonstrated many health benefits from weight loss, diabetes, a-topical skin diseases, it also
    works as a detoxification system, removing harmful free radicals from
    your body.
