PFAS Water Filter in Coral Springs

What PFAS are

Per- and polyfluoroalkyl substances have been used since the 1940s in nonstick, stain-resistant and water-repellent products and some firefighting foams. They break down slowly. PFOA and PFOS are the most studied. The EPA has been setting national drinking water limits for several PFAS; check the EPA's site for current limits and compliance dates.

What the providers report

• City of Coral Springs (2025 report): the unregulated contaminants table lists seven PFAS compounds, including PFOA and PFOS, at levels reported in micrograms per liter, from samples taken in December 2024 and June 2025. Unregulated contaminants have no drinking water standard in that table; the city reports them as required.
• NSID (2024 report): states that its 2023 UCMR5 sampling found no detectable levels of PFAS or lithium.
• CSID (2024 report): states that it participated in UCMR5 and includes a section explaining PFAS. For its specific results, ask CSID's Chief of Water Operations at (954) 796-6665.
• Royal Waterworks: check its report.

Read your own provider's numbers directly rather than relying on summaries, including this one.

Which filters to trust

Only systems certified to NSF/ANSI 53 (filters) or NSF/ANSI 58 (reverse osmosis) for PFOA/PFOS reduction have been tested for it. Certification is model-specific, so check the exact model number, including the replacement cartridge, on the certifier's listing. Living Water does not claim its systems remove PFAS; ask any seller for the exact model's certification before buying.

Why reports differ between providers

Coral Springs is an unusual case because four providers draw from different wells and treat water differently. The City uses lime softening, CSID uses reverse osmosis, and NSID uses nanofiltration and reverse osmosis on a blend of Biscayne and Floridan Aquifer water. Sampling dates also differ, from 2023 for NSID to December 2024 and June 2025 for the City. So a result from one provider says nothing about another provider's water. Use the city's Water Districts map or your bill to confirm your provider, then read that provider's report.

How to read a listing

• Standard: 53 or 58.
• Claim: PFOA/PFOS reduction specifically.
• Model: matches what you are buying.
• Capacity: the rated gallons before replacement.

Testing your own tap

PFAS testing requires a certified laboratory and careful sampling; an in-home screening cannot measure it. Private wells are not covered by any provider's testing. See well water in Coral Springs and screening vs. lab analysis.
