The short answer

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

What handles it

What was found

Arsenic: Virginia’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2023, with EPA’s 2012 to 2019 file for earlier years.

Nitrate, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5) and chromium (total): EPA’s compliance monitoring file, samples taken from Jan. 23, 2012 to Oct. 9, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Arsenic

Comes from the source

Above the health goal

3.5ppb

Highest yearly average, 2023

Averaged by year, the highest was 3.5 ppb, in 2023: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.0 ppb, in 2012.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Below EPA’s limits4

Nitrate

Comes from the source

Below EPA’s limits

2.3ppm

Highest sample; found in 23 of 31

2019 average: 1 ppm

The highest sample, in 2013, was 2.3 ppm, below EPA’s legal limit of 10 ppm. In 2019, the latest year on file, its five samples averaged 1 ppm.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

12.4ppb

Highest yearly average, 2012 to 2019

2019 average: 8.1 ppb

Averaged by year, the highest was 12.4 ppb, in 2014, below EPA’s legal limit of 80 ppb. Its highest single sample was 20 ppb. In 2019, the latest year on file, its two samples averaged 8.1 ppb.

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.15ppm

Highest yearly average, 2014 to 2018

2018: not found

Averaged by year, the highest was 0.15 ppm, in 2014, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.34 ppm. In 2018, the latest year on file, it wasn’t found in its one sample.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

0.85ppb

Highest yearly average, 2012 to 2019

2019: not found

Averaged by year, the highest was 0.85 ppb, in 2014, below EPA’s legal limit of 60 ppb. Its highest single sample was 3.4 ppb. In 2019, the latest year on file, it wasn’t found in any of its two samples.

No certification claim covers this compound yet.

  • Chromium (total)
  • Lead

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.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. 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 2023 on, with EPA’s national file for 2012 to 2019. Nitrate, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5) and chromium (total) come from EPA’s file alone, which ends in 2019. Vint Hill’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 Jan. 23, 2012 to Oct. 9, 2019.

Testing your own tap

Vint Hill’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.
