What the EPA limit means
700 µg/L
Maximum Contaminant Level — the enforceable ceiling a supplier must stay under.
700 µg/L
Health goal (MCLG) — the level with no known health effect. It is a goal, not a legal limit, and is often zero for carcinogens.

Where Ethylbenzene was found
The water suppliers reporting the highest levels, worst first. For lead and copper that is the 90th-percentile result the action level is written against; for Six-Year Review data, the 95th percentile of each system's samples.

Frequently asked questions about Ethylbenzene
What is Ethylbenzene in drinking water?
Ethylbenzene is monitored in US public drinking water under EPA rules. Each supplier's result is reported to the EPA and published here with its source and period.
What is the EPA limit for Ethylbenzene?
The EPA's Maximum Contaminant Level for Ethylbenzene is 700 µg/L, and its health goal (MCLG) is 700 µg/L. A result above the limit means the supplier must act; the goal is the level at which no health effects are expected.
How common is Ethylbenzene in US tap water?
Of the 34,515 water suppliers with results on file, 1,362 detected Ethylbenzene — 3.9% of those tested.
