Arkansas, Groundwater, contamination, pesticides


There is much unknown about the extent of pesticide contamination of groundwater in Arkansas. In recent years, several research studies have been conducted where wells for irrigation and domestic uses have been sampled and analyzed for pesticides (Lavy, 1988; USGS,1993; Nichols, et al., 1993). For state and federal regulatory agencies, evaluation of the potential ground water contamination begins with considering those areas in Arkansas where pesticides are used and where the ground water is vulnerable to contamination. With a relatively large area of crops grown in Arkansas and only limited financial resources available for chemical analyses by state and federal agencies, the question of where these agencies should begin to sample the ground water for pesticides is pertinent. Therefore, there is a need for the development of a scheme that can be used to optimize the available resources.
