Utility results describe the whole system, measured where water enters the pipes, not your tap. Your home’s plumbing can add lead or copper.
EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in Tarpon Springs Water System’s water between Feb 2023 and Sep 2023. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFOA10.5 pptFound in 4 of 6 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFOS36.9 pptFound in 4 of 6 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFHxS9.1 pptFound in 4 of 6 samples · highest resultNo federal limit in force for this one

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.
Radium and uranium
Found: Gross alpha (radioactivity), Radium (combined 226 + 228), Uranium
What removes it: Reverse osmosis.
Lead
Found: Lead
What removes it: Certified carbon block or RO.
PFAS ("forever chemicals")
Found: PFOA (EPA testing), PFOS (EPA testing)
What removes it: Reverse osmosis.
