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.

Is D & M Wsc tap water safe to drink?

EPA monitoring detected 25 contaminants in D & M Wsc's water. A detection isn't the same as a violation — most levels are within federal limits. See each level and source above, and the utility's annual Consumer Confidence Report for its official compliance status.

What contaminants were detected in D & M Wsc's water?

EPA monitoring detected Nitrate, Bromodichloromethane, Chloroform, Dibromochloromethane, Dichloroacetic Acid, and others. The full list with the level and data source for each is above.

How many people does D & M Wsc serve?

D & M Wsc reports serving 7,280 people in Texas, per its EPA record.

Has D & M Wsc had any water quality violations?

The EPA has 78 violations on file for D & M Wsc, of which 15 are health-based (a contaminant limit or required treatment was breached) and 1 remain open. The rest are monitoring or reporting failures.

Where does this data come from?

Every figure is official EPA drinking-water monitoring — the Lead & Copper Rule, the UCMR-5 nationwide testing program, and the EPA Six-Year Review — not our own testing. Each number is labelled with its source and period.
