To assess the occurrence, vertical distribution, and movement of the pesticide aldicarb in groundwater beneath agricultural fields.
Monitored groundwater beneath three primary and two subsidiary agricultural fields between December 1980 and August 1981.
Sampled 67 monitoring well points (including nested configurations), one multilevel sampler, 25 private domestic wells, and seven irrigation wells.
Aldicarb concentrated predominantly within a five-foot zone near the water table, yielding the highest detected concentrations in shallow monitoring wells.
Deep monitoring wells placed roughly 60 feet below the water table showed no detectable aldicarb, whereas select irrigation wells finished at similar depths contained detectable residues.
Significant seasonal fluctuations in aldicarb concentrations were detected across multiple monitoring wells over the study duration.

Implication

Field monitoring study reveals aldicarb concentrates in shallow water table layers across agricultural groundwater, highlighting seasonal leaching risks in vulnerable aquifers.
