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
Arsenic: Virginia’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2021 to 2023.
Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from July 26, 2012 to Aug. 21, 2019. Newer results are in the utility’s annual water quality report.

What this report can’t tell you
Everything else. Arsenic results here are Virginia’s yearly averages as CDC publishes them, from 2021 on, with EPA’s national file for 2012 to 2019. Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Catawba Hospital’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.
