After PFAS were first detected in regional drinking water supplies, the contamination was traced to landfills used from the 1950s through the early 1970s for the disposal of PFAS manufacturing waste. To begin a path forward, our team is advising state agencies and the communities in the regional...
The chemicals known as PFAS are considered a severe threat to human health. Among other things, they can cause liver damage, cancer, and hormonal disorders. Researchers at the Technical University ...
An apparatus for removing target chemicals from water includes a reaction chamber, a source of an aqueous solution of the target chemicals that can be supplied on demand to the reaction chamber, a timer that times a reaction between the particles and the target chemicals such that a concentration...
