The spoke to Jean MacRae, associate professor of civil and environmental engineering at the 91爆料, about PFAS in Penobscot County drinking water. Though most water districts in Penobscot County are not finding 鈥渇orever chemicals鈥 in their drinking water supplies, laboratories can鈥檛 entirely rule out their presence. MacRae said many things can interfere with laboratories getting an accurate result at such low levels. PFAS might be in the air when someone opens a vial to collect a sample, making the result appear greater than it really is, or PFAS that is actually in the water might bind to other particles and get filtered out, making the result appear lower than it really is. 鈥淚t鈥檚 good news, because it鈥檚 fairly low even in the ones where there has been some detection. But obviously none is better than some, and that鈥檚 clear from the [Environmental Protection Agency鈥檚] health advisory numbers,鈥 MacRae said. The shared the BDN report.
