EPA records reflect the public water system, not your home's plumbing. Health-based goals (EPA MCLG / WHO) are health targets and are often stricter than the federal legal limit (the MCL). A utility appearing on this list does not by itself mean the water is unsafe to drink. The only way to know what is in your specific home is to test your own water.
The health-based goal vs. the legal limit
The federal legal limit (MCL) is the maximum allowed by law. The health-based goal (EPA MCLG / WHO) is a stricter health target — not itself a legal limit.
Health-based goal (EPA MCLG / WHO)
