Compliance record

Formal violations the EPA has on file for this supplier. A health-based violation means a contaminant limit or a required treatment was breached; the rest are monitoring or reporting failures — still violations, but not a measured health risk.

Other contaminants detected

Each bar shows the measured level as a share of the EPA limit: green is well under, amber is close to it, red is over. For lead and copper the limit applies to exactly the 90th-percentile figure shown, so red there means a real exceedance. For everything else the limit applies to a running annual average while the figure is the 95th percentile of this system's samples — over 100% is worth reading, but is not by itself a violation. Where a single sample came in higher than that percentile, it is noted under the bar. Formal violations are listed separately.

What contaminants were detected in Lawton's water?

EPA monitoring detected TTHM, Total Haloacetic Acids (HAA5), Copper, Dibromochloromethane, Bromodichloromethane, and others. The full list with the level and data source for each is above.

How many people does Lawton serve?

Lawton reports serving 92,757 people in Oklahoma, per its EPA record.

Has Lawton had any water quality violations?
