2015 Reconnaissance Study of Pesticide Compounds in Community Public Water Supply Wells

The Minnesota Department of Health (MDH), in cooperation with the Minnesota Department of Agriculture (MDA), conducted a reconnaissance study of 135 pesticides and pesticide degradates at 108 Minnesota community public water system (CPWS) wells during February and March 2015. This study built upon the results of a 2010 reconnaissance study (MDA, 2010) through the use of improved analytical capabilities at the MDA Laboratory Services Division (MDA Laboratory) and MDH Public Health Laboratory (PHL). Community public water system participation was voluntary, and all MDA and MDH employee resources were funded through existing budgets.
