MAINE PUBLIC • February 1, 2023
So far, contamination has been found on 56 farms and 23% of the more than 1,500 groundwater samples that have been collected – both from agricultural sites and residential wells – have tested above Maine’s interim standard of 20 parts per trillion for the cumulative total of six types of PFAS. But while research into PFAS mitigation is ongoing, both in Maine and across the country, state officials said they are optimistic about initial success in reducing pollution levels in some livestock or farm products.
