The short answer

Nothing in EPA’s and Texas’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 2 health-based violations since 2016.

What was found

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.4 ppm, for the period ending Dec. 31, 2016. None since is on file, so it is not counted as a current finding.

Haloacetic acids (HAA5), fluoride, total trihalomethanes (TTHM), nitrate, arsenic, chromium (total) and uranium: Texas’s own results, samples taken from Feb. 24, 2020 to Sept. 30, 2025, with EPA’s 2012 to 2019 file for earlier years.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5), fluoride, total trihalomethanes (TTHM), nitrate, arsenic, chromium (total) and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Saint Paul Shiloh Timesville WSC’s own annual report, which it must send you every year, has the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Texas’s results run from Feb. 24, 2020 to Sept. 30, 2025.

Testing your own tap

Saint Paul Shiloh Timesville WSC’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Texas certifies.
