Five of the compounds detected have never before been reported in groundwater anywhere in the world. They're not per and polyfluoroalkyl substances (PFAS).
Despite a massive focus on PFAS substances and pesticide residues in Danish drinking water, little attention is paid to the hundreds of other chemical compounds in our groundwater.
Activated carbon is a charcoal-like substance that PFAS stick to quite well and can be used to remove PFAS from water. Ion exchange systems are typically even better, writes Joe Charbonnet.
The testing illustrates that residents on well water often don't know exactly what's in the water they're drinking, and they are given little guidance on maintenance as they alone are responsible.
Study examines remediation at a site that began in the 1990s, with groundwater monitoring since 2000, including measuring for PFAS and PFOS since 2015.
The U.S. Environmental Protection Agency issued a Notice of Intent on February 22 to delete three sites and partially delete eight other sites from the National Priorities List (NPL).
New Hampshire Department of Environmental Services will provide a one-time rebate to private well users for up to $5,000 for the installation of PFAS treatment or up to $10,000 for a service connection to a public water system.
