Interpretive Summary:

Technical Abstract: Groundwater resources in semiarid lands of central Argentina are currently threatened by contamination from agricultural pesticides. This chapter addresses the vulnerability and risk assessment of the quaternary aquifer system to pesticide pollution. We used pesticide DRASTIC Index and PIRI GIS-based models to assess the groundwater vulnerability and leaching potential of commonly used herbicides. DRASTIC and PIRI maps were compared against herbicide detections in the aquifers underlying the study area to indicate the applicability of these approaches to semiarid lands of central Argentina.
