A member of Congress is seeking to ban one of the nation’s most widely-used herbicides, which has turned up in drinking water in some states. Rep. Keith Ellison (D-Minn.) is for the second time proposing legislation that would outlaw any use or trade of atrazine.

Atrazine is most commonly sprayed on cornfields, and can run off into rivers and streams that supply drinking water. As the Huffington Post Investigative Fund reported in a series of articles last fall, the U.S. Environmental Protection Agency failed to warn the public that the weed-killer had been found at levels above federal safety limits in drinking water in at least four states. A coalition of Midwestern communities — along with the nation’s largest private water utility — is suing atrazine’s manufacturer, Syngenta, seeking to have it pay to filter the chemical from public water.

Steven Goldman, spokesman for Syngenta, did not comment specifically on the proposed bill or on the prospect of a nationwide ban.

Not sure if your drinking water contains atrazine or other potentially harmful drinking water contaminants? The following information about testing for atrazine might come in handy, then:

If you live w/in 50 to 100 miles of an agricultural area and have a well, or your local water system draws from a well located near agricultural areas, either get your water tested for atrazine as well as other pesticides and herbicides several times a year — especially after periods of heavy rain and/or runoff.

Test kits such as the Pesticide Test Kit for atrazine and simazine work well as occasional screening methods but when it comes to giving the final word on whether or not your water contains harmful contaminants, always turn to the experts at a certified drinking water testing lab such as National Testing Labs.

Despite growing health concerns about atrazine, an agricultural weedkiller sprayed on farm fields across the Midwest, most drinking water is tested for the chemical only four times a year — so rarely that worrisome spikes of the chemical likely go undetected.

High levels of the herbicide can linger in tap water during the growing season, according to more frequent tests in some agricultural communities.

Spread heaviest on cornfields, atrazine is one of the most commonly detected contaminants in drinking water. Studies have found that exposure to small amounts of the chemical can turn male frogs into females and might be more harmful to humans than once thought.

…

Even with limited official testing, atrazine in the past four years was detected in the drinking water of 60 Illinois communities where more than a million people live, according to a Tribune analysis of state and federal records.

Under a deal between the EPA and the chief manufacturer of atrazine, about 130 water utilities in 10 states are tested weekly or biweekly. The Tribune analysis showed that during 2008, four downstate towns — Evansville, Farina, Flora and Mount Olive — were among nine Midwest communities where the average annual level of atrazine and its breakdown products exceeded the federal safety limit of 3 parts per billion. About half of the 130 saw concentrations that jumped above 3 parts per billion at least once that year.

In Flora, about 240 miles south of Chicago, atrazine levels spiked as high as 30 parts per billion. The findings concern researchers because some studies have shown adverse affects from exposure to concentrations as small as 0.1 parts per billion. The chemical has not been found in Chicago tap water, in part because Lake Michigan dilutes farm runoff.

The more frequent tests are done outside the EPA’s official monitoring program and don’t count when regulators consider whether communities meet the legal limit for atrazine.

They also don’t trigger provisions in the federal Safe Drinking Water Act that require the public to be notified about water contamination. As a result, residents are rarely advised that they can buy inexpensive filters to screen the chemical out of their tap water.

Atrazine can’t be sprayed in Europe because it contaminates groundwater, but it remains widely used in the U.S., where the EPA endorsed its continued use as recently as 2006, based on a scientific review from 2003. Federal records show the review was heavily influenced by industry and relied on studies financed by Syngenta, a Swiss-based company that manufactures most of the atrazine sprayed in the U.S. ( source )

The last paragraph cited above pretty much says it all: The word of the chemical manufacturer, and not that of an independent organization, got used to shape and mold public policy regarding the testing and regulation of atrazine.

Yesterday, the Environmental Protection Agency (EPA) announced that it is re-evaluating health outcomes linked to a commonly used pesticide, atrazine, that has been discovered in drinking water, said the Associated Press (AP). Atrazine is typically used on corn and other crops.

The AP noted that, based on research, rainstorm runoff can contaminate streams and rivers, contaminated water systems. The EPA looked at 150 drinking water systems in America’s Midwest because that is where the chemical is used most frequently, said the AP. The EPA has not detected atrazine at the levels that would prompt adverse health problems, such as cancer; however, emerging studies indicate that even at lower levels, atrazine’s presence in drinking water can result in “low birth weights, birth defects and reproductive problems,” said the AP.

Can the average person test for atrazine in drinking water? Yes, but anyone with serious reason to suspect drinking water contamination should have their water tested by a certified water testing laboratory such as Suburban Water Labs.

Do-it-yourself test kits like the Quick Pesticide in Water Test Kit work well as screening tools but do not provide the ‘last word’ when it comes to drinking water safety.

In an article by Jeff Barnard (Associated Press Writer) published on Yahoo News on Thursday August 14, 2008. . .

“GRANTS PASS, Ore. – Three pesticides commonly used on farms and orchards throughout the West are jeopardizing the survival of Pacific salmon, the federal agency in charge of saving the fish from extinction has found.

Under the settlement of a lawsuit brought by anti-pesticide groups and salmon fishermen, NOAA Fisheries has issued a draft biological opinion that found the way chlorpyrifos, diazinon and malathion get into salmon streams at levels high enough to kill salmon protected by the Endangered Species Act.

. . .

Banned from many household uses, tens of millions of pounds of the chemicals are still used throughout the range of Pacific salmon on a wide range of fruits, vegetables, forage crops, cotton, fence posts and livestock to control mosquitoes, flies, termites, boll weevils and other pests, according to NOAA Fisheries.

. . .

The chemicals are the first of 37 that NOAA Fisheries and EPA must evaluate by 2012 under terms of a settlement reached last week in a lawsuit brought by Northwest Coalition Against Pesticides and the Pacific Coast Federation of Fishermen’s Associations, which represents California commercial salmon fishermen.

A total of 28 species of Pacific salmon are classified as threatened or endangered from overfishing, dams, logging, grazing, urban development, pollution, irrigation, misguided hatchery practices and other threats.

Lecky said he could not say where pesticides rank in the threats to salmon, but eliminating the harm from pesticides would boost efforts to save them.”

This naturally leads all of us here at Water Testing Blog to wonder what sort of effect those same compounds may have on human life.

With that in mind, we sought out testing methods for ‘common’ pesticides currently viewed as harmful and/or toxic to human life and sometimes found in well, surface, and drinking water. We discovered the Pesticides in Water test kit which detects Atrazine and Simazine in drinking water at levels established by the United States Environmental Protection Agency as harmful to humans.

The Pesticides in Water test kit detects Simazine at the Maximum Contaminant Level (MCL) of 4 parts per billion and Atrazine at the Maximum Contaminant Level (MCL) of 3 parts per billion.

As always, though, if you have serious reason to suspect the accidental or intentional addition of harmful chemicals to your drinking water supply, we suggest you seek the testing services of trained water professionals.
