Pesticides in Ground Water Data Base. 1988 Interim Report

摘要

One of EPA's priorities is to determine the extent of pesticides occurring in the nation's ground water. The Pesticides in Ground Water Data Base was developed to compile the results from monitoring studies conducted by pesticide registrants, universities, and government agencies. The data base identifies the pesticides that have been looked for in ground water, the areas that have been monitored, and the pesticides that have been detected. An important component in the development of the data base is the data confirmation program which involves contacting the director or responsible agent for each study in order to document and assess the sample collection and analysis procedures used in the study. The report outlines the development of the data base, the data confirmation program, and how the data base will be used by EPA to support the registration process for pesticides. The report attempts to segregate the results according to the quality of the study and the origin of contamination (i.e., point source origins vs leaching through the soil following applications in accordance with registration). The report is an interim report in that the data confirmation program continues and new data is added to it daily.
