Andover, Minn. homeowners share concerns about lack of information on contaminated water

The Minnesota Pollution Control Agency was conducting routine water sampling near a closed water disposal landfill when the chemical was discovered earlier this year. It's only been found in homes with private residential wells, and not in the city's municipal water supply. Scientists still haven't identified the source of the contamination. The MPCA is now conducting a study looking at connecting the impacted homes to the city's water supply.
