One major gap in the proposed HHS policy is that it does not apply to grantees, and much of the scientific work done in the U.S. takes place under grants.
There are more than 12,000 types of PFAS, not all of which can be detected with current tests; the U.S. Geological Survey study tested for the presence of 32 types.
At least 45% of the nation’s tap water is estimated to have one or more types of the chemicals known as per- and polyfluorinated alkyl substances, or PFAS, according to a new study by the U.S. Geological Survey.
Accurate sampling of PFAS is vital because the data received provides insights into their potential health risks and what strategies should be used for remediation or water treatment.
