The original published file, referenced from the source record.
Detected at up to 10.6 ng/L (above the 4.0 ng/L federal limit).
Why it matters. Studies associate PFOA exposure with effects on the immune system, cholesterol, liver, and developmental outcomes, and with certain cancers. Because it accumulates, the EPA has set the enforceable limit near the lowest reliably measurable level.
What you can do. Relevant treatment: Reverse osmosis, Activated carbon (GAC), Anion exchange.

A federal limit (an MCL or action level) is an enforceable legal cap. A health goal (an MCLG or health benchmark) is a non-enforceable target, often stricter, sometimes zero. A system meeting the legal limit is a compliance fact; it is not a guarantee of no health concern. PurityMap publishes no overall compliance verdict for a system; read each finding against its own reference below.
MDWASA/REX UTILITIES (PWS ID FL4131202) is a public water system serving 45,200 people in Mdwasa/rex, Florida.
MDWASA/REX UTILITIES is on record as drawing from groundwater. The source shapes which contaminants matter most for this system.
PurityMap's record for MDWASA/REX UTILITIES shows 2 findings measured above a benchmark and 2 within benchmark, from 4 evidence records. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.
PurityMap does not issue a safety verdict. It publishes MDWASA/REX UTILITIES's measured results against each contaminant's benchmark so you can read them in context. Safety depends on the specific finding, your plumbing, and how the water reaches your tap.
The latest published record for MDWASA/REX UTILITIES is dated 2026-09-16. Utilities report on regulatory cycles, so results reflect the monitoring period rather than a live reading.
