Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Atrazine in Surface Waters: A Report of the Atrazine Task Group to the Working Group on Water Quality; April 1992 In February 1989, the President's Initiative on Water Quality proposed a vigorous national effort to protect groundwater and surface waters from contamination by agricultural chemicals and wastes, especially pesticides and nutrients. Named the lead agency in the Initiative, the usda developed a Water Quality Program to minimize the risk of contaminating groundwater and surface waters with agricultural chemicals. The Working Group on Water Quality (wowo) is an interdepartmental group established to carry out this program. It includes 12 usda agencies, along with the us. Geological Survey (usgs); the us. Environmental Protection Agency (epa); the National Oceanic and Atmospheric Administration (noaa); the us. Army Corps of Engineers; the Fish and Wildlife Service; and the Tennessee Valley Authority (tva). As another part of the President's Initiative, the usgs monitored the Mississippi River and some of its tributaries to determine the presence, levels, and variability of selected pesticides in the water. They found that 1) increased concentrations of dissolved atrazine occur in the river system for 4 to 6 weeks following corn planting; 2) the concentrations of dissolved atrazine vary by as much as one order of magnitude above background levels; 3) increased levels are associated with rainfall; 4) individual elevations are relatively short-lived; and 5) levels occasionally exceed three parts per billion (ppb). It should be noted that background levels, generally, are in the range of ppb or less; that some observed spikes have exceeded 12 ppb; and that the fate of atrazine spikes has not been studied with regard to their dilution during movement in rivers.

Available in PDF, EPUB and Kindle. Book excerpt: Most people know about the presence and health effects of pesticide residues in the water they drink. However, they may not realize the impact of atmospheric transportation and deposition of pesticides on water quality. Scientific studies of pesticides in various atmospheric matrices (air, rain, snow, aerosols, and fog) provide some of the answers.
Download or read book Identifying Future Drinking Water Contaminants written by National Research Council and published by National Academies Press. This book was released on 1999-09-30 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an increasing population, use of new and diverse chemicals that can enter the water supply, and emergence of new microbial pathogens, the U.S. federal government is faced with a regulatory dilemma: Where should it focus its attention and limited resources to ensure safe drinking water supplies for the future? Identifying Future Drinking Water Contaminants is based on a 1998 workshop on emerging drinking water contaminants. It includes a dozen papers that were presented on new and emerging microbiological and chemical drinking water contaminants, associated analytical and water treatment methods for their detection and removal, and existing and proposed environmental databases to assist in their proactive identification and regulation. The papers are preceded by a conceptual approach and related recommendations to EPA for the periodic creation of future Drinking Water Contaminant Candidate Lists (CCLsâ€"produced every five yearsâ€"include currently unregulated chemical and microbiological substances that are known or anticipated to occur in public water systems and that may pose health risks).
