Projects to prioritize environmental justice areas
The MPCA sought proposals from qualified responders to conduct an environmental forensics evaluation using non-targeted analysis techniques for identifying sources of non-aqueous film forming foam (non-AFFF) per- and polyfluoroalkyl substances (PFAS) contamination in water.
Minnesota samples a network of shallow monitoring wells designed to provide early detection of contamination in the groundwater.
MPCA staff studied the river during this summer's extreme drought conditions to see if tighter limits on phosphorus are protecting aquatic life.
Minnesota rules require many facilities that produce air emissions to conduct performance testing.
The purpose of the Minnesota Pollution Control Agency's official social media accounts is to provide information about the MPCA and the programs, services, and products we provide. The MPCA social…
To protect human health and the environment, we need to limit the amount of per- and polyfluoroalkyl substances (PFAS) in our waters to safe levels. Safe levels means water can be used for drinking,…
