The short answer

Nothing in EPA’s and CDC’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. No health-based violations on file 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 1.5 ppm, for the period ending July 1, 1993. None since is on file, so it is not counted as a current finding.

Arsenic: Virginia’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2023.

Nitrate, haloacetic acids (HAA5), fluoride, chromium (total) and total trihalomethanes (TTHM): EPA’s compliance monitoring file, samples taken from Sept. 17, 2012 to Sept. 11, 2019. Newer results are in the utility’s annual water quality report.

One sample

2012, one sample: 2.8 ppm

What this report can’t tell you

  • Everything else. Arsenic results here are Virginia’s yearly averages as CDC publishes them, from 2023 on, with EPA’s national file for 2012 to 2019. Nitrate, haloacetic acids (HAA5), fluoride, chromium (total) and total trihalomethanes (TTHM) come from EPA’s file alone, which ends in 2019. Overlook Heights Combined’s own annual report, which it must send you every year, has newer results for those and 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; CDC’s yearly averages for Virginia cover 2023; EPA’s compliance samples are from Sept. 17, 2012 to Sept. 11, 2019.

Testing your own tap

Overlook Heights Combined’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 Virginia certifies.
