What is the source of contamination?

The source of the contamination has not yet been determined.

Typically, Minnesota Pollution Control Agency (MPCA) staff try to find the sources of contaminants. MPCA staff collected and analyzed samples from monitoring wells, industrial wells, irrigation wells and other municipal wells located in the western Twin Cities metro area. The results showed a “volatile organic compound trail” that allowed the MPCA to trace the contamination back 2.3 miles, to a contamination site in St. Louis Park.

The MPCA has narrowed the list of contaminators to five properties. However, MPCA has exhausted funding in identifying the exact source of contamination.
