The Portland Water District says its water is PFAS-free.

According to the Portland Press Herald, officials made the announcement after receiving results of tests conducted this summer.

PFAS have been found in farm fields and some water supplies around the state.

The state has mandated testing in schools, nursing homes and water systems.

Also known as “forever chemicals,” PFAS have been linked to several types of cancer.

It was the first PFAS test for the Portland Water District since 2019.

In a related story, more than a half dozen schools in Maine will start the new school year with concerns about PFAS in their drinking water.

Mount Desert Island High School and Chebeague Island School are among the schools that have installed water filters.

That after testing showed PFAS levels exceeded the state’s allowable limit of 20 parts per trillion.
