Ongoing testing is showing just how prevalent a group of toxic chemicals linked to serious health issues in humans is in Maine.

Dangerous levels of PFAS and PFOS, better known as “forever chemicals” have shown up in central Maine soils, well water, dairy farms, deer meat and chicken eggs. Last week it forced a farm in Unity to halt sales of its products after its soil, water and produce tested positive for the toxins.

The Maine Department of Environmental Protection is now actively testing multiple former sludge and septage application sites around the state for the presence of those chemicals.
