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 Aqua Wsc tap water safe to drink?
EPA monitoring detected 25 contaminants in Aqua 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 Aqua Wsc's water?
EPA monitoring detected Copper, Dibromochloromethane, Bromodichloromethane, Bromoform, Chloroform, and others. The full list with the level and data source for each is above.
How many people does Aqua Wsc serve?
Aqua Wsc reports serving 86,325 people in Texas, per its EPA record.
Has Aqua Wsc had any water quality violations?
