Researchers find high levels of PFAS chemicals in rainwater in United States
News
18 Dec 2019 | The Weather Channel
Most of the samples had PFAS concentrations of less than 1 ng/l, or 1 ppt, but several were about 4 ng/l. The highest total concentration was nearly 5.5 ng/l in a sample from Massachusetts. For drinking water, some states have proposed setting the level at which some type of official action is required at 2 nanograms per liter.
