Abstract:

Study Objectives: Emphasis was on the fate and transport of atrazine and its metabolites in the soil and the unlithified deposits overlying the bedrock aquifer that serves as the source of drinking water for most area residents. The investigation of unlithified deposits determines to what extent movement of residues through these deposits can serve as the source of contamination of the bedrock aquifer. Although some private bedrock wells were sampled occasionally, a thorough investigation of the bedrock system was beyond the scope of this study. Objectives were to gain insights into pesticide transport in the soil and unlithified deposits and to assess the temporal and spatial sources of the contamination.
