Report : Still Poisoning the Well – Atrazine Continues to Contaminate Surface Water and Drinking Water in the United States

Follow up to previous postings on atrazine, a new report via the The Natural Resources Defense Council, Still Poisoning the Well – Atrazine Continues to Contaminate Surface Water and Drinking Water in the
United States
: “Banned in the European Union and clearly linked to harm to wildlife and potentially to humans, the pesticide atrazine provides little benefit to offset its risks. In 2009, NRDC analyzed results of surface water and drinking water monitoring data for atrazine and found pervasive contamination of watersheds and drinking water systems across the Midwest and Southern United States. This May 2010 report summarizes scientific information that has emerged since the publication of our initial report and includes more recent monitoring data. Approximately 75 percent of stream water and about 40 percent of all groundwater samples from agricultural areas tested in an extensive U.S. Geological Survey study contained atrazine. NRDC found that the U.S. EPA’s inadequate monitoring systems and weak regulations have compounded the problem, allowing levels of atrazine in watersheds and drinking water to peak at extremely high concentrations. The most recent data confirms that atrazine continues to contaminate watersheds and drinking water. Atrazine was found in 80 percent of drinking water samples taken in 153 public water systems. All twenty watersheds sampled in 2007 and 2008 had detectable levels of atrazine, and sixteen had average concentrations above the level that has been shown to harm plants and wildlife.”
