The short answer

1 result is above the health goal. The worst: Lead, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2024.

Arsenic: Virginia’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2021.

Nitrate, chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from July 10, 2012 to Aug. 13, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

15ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 15 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027, and this result is at or above that. EPA’s health goal for lead is zero.

What handles it

Below EPA’s limits1

Nitrate

Comes from the source

Below EPA’s limits

2.5ppm

Highest sample; found in 8 of 8

2019, one sample: 0.31 ppm

The highest sample, in 2014, was 2.5 ppm, below EPA’s legal limit of 10 ppm. In 2019, the latest year on file, its one sample was 0.31 ppm.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Chromium (total)
  • Fluoride

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

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. Nitrate, chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Randle Ridge’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 2021; EPA’s compliance samples are from July 10, 2012 to Aug. 13, 2019.

Testing your own tap

Randle Ridge’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.
