New thesis on PFAS remediation

Thesis cover.

Mattias Sörengård has in his doctoral thesis studied how soil contaminated by per- and polyfluoroalkyl substances can be remediated.

Per- and polyfluoroalkyl substances (PFAS) are used in a variety of products such as jackets, popcorn packaging, firefighting foam and makeup. Some PFAS have been shown to have harmful effects and humans can be expose via drinking water. The source of PFAS in drinking water is often contaminated soil, particularly from locations where PFAS-containing firefighting foam has been used in large quantities. PFAS can then continuously leak to the groundwater, which is in some cases used as drinking water.

In order to protect drinking water from contamination, the contaminated soil needs to be remediated, and so far, only a few studies have looked at different techniques for effective remediation of PFAS-contaminated soil.

Mattias Sörengård has in his thesis evaluated techniques for remediation of PFAS-contaminated soil to protect drinking water supplies and thus prevent human exposure. The thesis is defended in Audhumbla in the VHC building, Ultuna, on 22 September 2020. The public defence can also be followed via Zoom.
