What is the quality of South Dakota’s groundwater? Several studies have been conducted to evaluate pesticide contamination of shallow aquifers in this state. In east central South Dakota from 198401990, 1,628 samples taken from 114 monitoring wells found 11% of the samples contained detectable levels of at least one pesticide. Another study during 1988-1994 detected pesticides in 16% of 1,190 samples from 45 wells.
