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.

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.
