According to the StarTribune, the Minnesota Pollution Control Agency (MPCA) is recommending that a portion of an Andover, Minnesota neighborhood be connected to the city’s municipal water system after 40 homes with private wells were found to be contaminated with high levels of the cancer-causing chemical 1,4-dioxane. The homes are located near the now defunct Waste Disposal Engineering Landfill, which was declared defunct in 2019 and now managed by the MPCA. Other homes in the area connected to the city’s municipal water system were not affected.
Original sampling last summer showed about 40 wells affected. One well tested 2,200 times the value for the Minnesota Department of Health’s safe drinking water values. According to the MPCA, recently completed resampling of the wells showed no changes to the original results. Gov. Tim Walz has asked that $12 million be included in a bonding bill to connect affect homes to city water at no cost to homeowners.
