FY15 Evaluating Contaminants of Emerging Concern in Groundwater at Wastewater Land Application Sites

Groundwater sample collection and analysis will be conducted for contaminants of emerging concern (CEC) at large subsurface treatment systems (LSTS) and rapid infiltration basins (RIB), using an enzyme linked immunosorbent assay (ELISA) methodology. Results from the ELISA analysis will be reported to the MPCA and used to conduct follow-up investigations at a select number of these sites.

Monitoring results will be used to improve the assessment of water quality conditions and to quantify long-term water quality trends in non-agricultural areas of the state. Data collected will help explain the occurrence of CEC detected in areas of the state where no identified sources of CEC are known to be present.
