"A Twin Cities town is trying to get to the bottom of a mystery with its drinking water.

Crews contracted by the Minnesota Pollution Control Agency are drilling deep into the ground in Robbinsdale to find the source of a concerning chemical.

The city's water supply slightly exceeds the federal limit for PFAS, a forever chemical found in common household items like nonstick pans. The standards set by the Environmental Protection Agency require no more than 4 parts per trillion of PFAS in a public water supply. Robbinsdale's water tested at an average of 6 ppt, according to a 2025 report."
