Utility results describe the whole system, measured where water enters the pipes, not your tap. Your home’s plumbing can add lead or copper. 2 numbers we weren’t sure about are held back until a person checks.
EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in Santa Fe Springs - City, Water Dept.’s water between Dec 2023 and Sep 2024. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFOA6.9 pptFound in 2 of 6 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFOS14 pptFound in 2 of 6 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFBS5.2 pptFound in 2 of 6 samples · highest resultNo federal limit in force for this one
- Lithium45 ppbFound in 4 of 6 samples · highest resultAbove EPA’s health reference level of 10 ppb (a guide, not a legal limit)
Source: EPA UCMR 5 occurrence data. The highest single result is shown; one high sample doesn’t mean every glass is that high.
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.

Found: Copper
What removes it: Reverse osmosis.
PFAS ("forever chemicals")
Found: PFOA (a PFAS), PFOS (a PFAS), PFOA (EPA testing), PFOS (EPA testing)
What removes it: Reverse osmosis.
