This powerpoint presentation outlines a national atrazine occurrence survey conducted in 2003 and 2004 to gain a better understanding of atrazine short-term occurrence and variability. Key findings from the project include: many drinking water treatment plants had already installed treatment (e.g., granular activated carbon [GAC] or powdered activated carbon [PAC]) specifically for atrazine control and management, which implies that utilities are bearing the burden of cost for atrazine removal; and, the project was unable to evaluate the cost of atrazine management/treatment on drinking water treatment plants. The presentation also presents a national Agricultural Contamination Cost Survey to determine the costs utilities were paying for agricultural contamination from: Atrazine; Acetochlor; Nitrate; Nutrients. Primary survey components included: Demographics: system type, population served, etc.; and, agricultural contamination. Survey results presented include: demographics; agricultural contamination; treatment; and, cost summary.
