EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in Richmond County Water System’s water between Sep 2023 and Jul 2024. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFOS4.7 pptFound in 4 of 7 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFBS3.1 pptFound in 1 of 7 samples · highest resultNo federal limit in force for this one
- Lithium12 ppbFound in 2 of 8 samples · highest resultAbove EPA’s health reference level of 10 ppb (a guide, not a legal limit)

What you can do
Nothing here is an emergency notice: if the district has a violation, it must tell customers directly. If you’d like to lower these at your tap, these are the treatments that remove them, and the catalog shows the models certified for each. Ranking is by certified removal; commissions never change the order.

PFAS ("forever chemicals")
