Claim by claim

A source study was identified, but the study's evidence could not be prepared for claim assessment. The claims below have not been assessed.

Claim 1 of 5Not checkedCommon ways of reporting PFAS may underestimate the concentration of PFAS in United States drinking water by as much as half.View evidenceHide evidence

As statedas much as half

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 2 of 5Not checkedBy counting PFAS levels that fall below minimum reporting levels as zero, current reports capture only 44% of the average concentration of 25 PFAS in community water systems.View evidenceHide evidence

As stated44%

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 3 of 5Not checkedThe researchers analyzed more than 1.8 million PFAS measurement records in the EPA national dataset and found that 98% of PFAS test results were below the minimum reporting level.View evidenceHide evidence

As statedmore than 1.8 million records; 98% below MRL

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 4 of 5Not checkedFor the six PFAS with legally enforceable limits, the team estimated a national average concentration of about 5.2 nanograms per liter instead of about 2.6 nanograms per liter when below-limit results are treated as zero.View evidenceHide evidence

As statedabout 5.2 ng/L vs 2.6 ng/L

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 5 of 5Not checkedThe authors say the study only examines how PFAS measurements are summarized and does not establish that every below-limit result poses a health risk.View evidenceHide evidence
