Where is PFAS in Maine?
In Maine, PFAS has been found in agricultural sites, drinking water supplies, surface waters, landfills, wastewater, sludge and septage spreading sites, and remediation and cleanup sites and has become a serious contaminant. This contamination has come from the sludge and septage that has been added onto sites to supplement the land with nutrients.
Sludge is a solid, semi-solid, or liquid waste generated from a wastewater treatment process as well as from dewatered septage. Septage is a fluid mixture of sewage solids, liquids and sludge of domestic origin, which is collected in and removed from a septic tank system.
