When water flows through the material, it snags and traps PFOA molecules, effectively removing the forever chemical. In lab ...

Bucks and Montgomery County residents who live near military bases had higher levels of four “forever chemicals” known as ...

Drinking water in developed countries is pretty clean, but hidden nasties can still lurk. One mysterious “phantom chemical” has haunted drinking water for decades, and now researchers have ...

They measured the compound’s concentration content in a range of chloraminated U.S. water systems, detecting levels as high as about 100 micrograms per liter — surpassing most regulatory ...

The Pennsylvania Department of Environmental Protection adopted new limits on two of the toxic class of chemicals known as PFAS. Often referred to as “forever chemicals” because they don’t naturally ...

The work to remove the chemical compound is costing the water authority an estimated $1,000,000 per year. “I don’t think it’s going to be a significant effect on rates but it will have to be ...

Pennsylvania’s new regulations would restrict the PFAS compounds PFOS (perfluorooctane sulfonic acid) at 14 parts per trillion, and PFOA (perfluorooctanoic acid) at 18 parts per trillion.

But to understand the full scale of the chemical universe, you need to understand chemical compounds too. Some occur naturally – water, of course, is made of hydrogen and oxygen.
