US wetlands ‘restored’ using treated sewage tainted with forever chemicals

Use of wastewater treatment plant effluent containing Pfas threatens wildlife, food and drinking water, advocates say

Many of the nation's wetlands are being filled with toxic Pfas forever chemicals" as wastewater treatment plant effluent tainted with the compounds is increasingly used to restore swampland and other waters. The practice threatens wildlife, food and drinking water sources, environmental advocates warn.

Effluent is the liquid discharged by wastewater treatment plants after it disinfects" sewage in the nation's sewer system. The treatment process largely kills pathogens and the water is high in nutrients that help plants grow, so on one level it is beneficial to struggling ecosystems.
