Emerging Contaminants in Shallow Groundwater in Minnesota, 2012 – 2014

This project will determine the magnitude and frequency of contamination from endocrine active compounds (EAC's) and other contaminants of emerging concern in shallow groundwater in non-agricultural areas of Minnesota. EACs and other contaminants of emerging concern in this study include compounds typically found in waste water, including, pharmaceutical compounds, antibiotics, and hormones. This project supports the third phase, including laboratory analysis of samples for an additional 80 wells to be sampled by MPCA staff. Forty wells will be sampled during the 2013 field season, and 40 wells will be sampled during the 2014 field season. The USGS National Water Quality Laboratory and the Organic Geochemistry Research Laboratory will perform the laboratory analyses.
