The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. 2 health-based violations since 2016.

What handles it

What was found

Arsenic, uranium, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate and chromium (total): Colorado’s own results, samples taken from June 8, 2020 to March 23, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

3.0ppb

Highest yearly average, 2020

Averaged by year, the highest was 3.0 ppb, in 2020: 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 3.0 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”

Uranium

Comes from the source

Above the health goal

6.3ppb

Highest yearly average, 2025

Averaged by year, the highest was 6.3 ppb, in 2025: below EPA’s legal limit of 30 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 4.0 ppb, in 2018.

What handles it

Below EPA’s limits5

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

10.9ppb

Highest yearly average, 2021 to 2024

2024, one sample: 9.9 ppb

Averaged by year, the highest was 10.9 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2024, the latest year on file, its one sample was 9.9 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.6 ppb, in 2012.

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.35ppm

Highest yearly average, 2020

Averaged by year, the highest was 0.35 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.53 ppm, in 2012.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

3.0ppb

Highest yearly average, 2021 to 2024

2024, one sample: 2.6 ppb

Averaged by year, the highest was 3.0 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2024, the latest year on file, its one sample was 2.6 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.3 ppb, in 2012.

What handles it

No certification claim covers this compound yet.

Nitrate

Comes from the source

Below EPA’s limits

0.4ppm

Highest sample; found in 2 of 7

2026: not found

The highest sample, in 2024, was 0.4 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 3.6 ppm, in 2019.

What handles it

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

Chromium (total)

Comes from the source

Below EPA’s limits

3.0ppb

Highest yearly average, 2020

Averaged by year, the highest was 3.0 ppb, in 2020, below EPA’s legal limit of 100 ppb. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.0 ppb, in 2012.

What handles it

One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • 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

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Uranium

    For: Arsenic, Uranium

    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, uranium, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate and chromium (total) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Buckskin Valley Subdivision’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; Colorado’s results run from June 8, 2020 to March 23, 2026.

Testing your own tap

Buckskin Valley Subdivision’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 Colorado certifies.

No lab Colorado certifies is within 75 miles of the area Buckskin Valley Subdivision serves on the state’s list. Some take samples by mail; the state’s page lists them all.
