Atrazine Concentrations in the Delaware River, Kansas u G Contamination of surface and ground water from nonpoint agricultural sources is a national issue. Nonpoint-source con taminants from agricultural activities include pesticides, sediment, nutrients (nitrogen and phosphorus), and fecal bac teria. Of these contaminants, pesticides inCited by: 2. Concentrations and transport of atrazine in the Delaware River-Perry Lake system, northeast Kansas, July through September SA2 no Analysis of ground-water flow and saltwater encroachment in the shallow aquifer system of Cape May County, New Jersey. Atrazine is a herbicide of the triazine class. It is used to prevent pre- and postemergence broadleaf weeds in crops such as maize (corn) and sugarcane and on turf, such as golf courses and residential lawns. Atrazine's primary manufacturer is Syngenta and it is one of the most widely used herbicides in US and Australian agriculture.. As of , atrazine was the most commonly detected Appearance: colorless solid. Concentrations and transport of atrazine in the surface water of the Delaware River-Perry Lake system, northeast Kansas, July through September / ([Washington, D.C.?]: U.S. Dept of the Interior, U.S. Geological Survey ; Denver, CO: For sale by the U.S. Geological Survey, Branch of Information Services, [?]), by Larry M.

The Big Blue River (Upper Gage) site exceeded in five out of six years of monitoring ; As a result, the agency has been working with atrazine registrants to ensure additional mitigation steps are taken consistent with requirements of the IRED ( pp, MB, about PDF) and Memorandum of Agreement (36 pp, KB, about PDF). Pesticides are important for agriculture in the United States, and atrazine is one of the most widely used and widely detected pesticides in surface water. A better understanding of the mechanisms by which atrazine and its degradation product, deethylatrazine, increase and decrease in surface waters can help inform future decisions for water-. This report describes a study to identify the distribution and extent of areas potentially at risk for atrazine (a broad leaf weedkiller) runoff in the Lake Lavon watershed, which is a major water supply for the Dallas area. The report presents the results of the study and makes recommendations for how information can be used in a cost-effective watershed atrazine reduction : Samuel F. Atkinson, William T. Waller, Kenneth L. Dickson, Sirichai Sanmanee, Maria C. Moreno. According to the Berkeley study, atrazine can be found in concentrations as high as 21 ppb in ground water, ppb in river basins in agricultural areas, ppb in some streams and up to 2, Author: Jonathan Stein.
Obion Middle Fork TN Vermilion River, North IN Poisoning the Well: How the EPA Is Ignoring Atrazine Contamination in Surface and Drinking Water in the Central United States atrazine. In , atrazine concentrations in 18 communities exceeded the legal limit of 3 ppb, sometimes for weeks. For example, atrazine contamination peaked at 32 ppb in Blanchester, Ohio, from May 5 to June 9, and at 21 ppb in Beloit, Kan., from June 9 to July 7. The EPA monitoring program targets water systems most vulnerable to atrazine contamination. Atrazine may protect crops and lawns from certain types of weeds, but it is a real problem for other species. The chemical is a potent endocrine disruptor that causes immunosuppression, hermaphroditism and even complete sex reversal in male frogs at concentrations as low as parts per billion (ppb)—well below the ppb that the U.S. Environmental Protection Agency (EPA) says is : Larry West.
