The short answer
1 result is above the limit’s level with no violation recorded, and 1 more is above the health goal. The worst: Uranium, above the limit’s level, no violation. 6 health-based violations since 2016.
What handles itWhat was found
Uranium, arsenic, nitrate, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5) and chromium (total): Colorado’s own results, samples taken from Dec. 17, 2020 to Sept. 29, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the limit’s level, no violation recorded1
Uranium
Comes from the source
31.9ppb
Highest yearly average, 2021 to 2023
2023, one sample: 19 ppb
Averaged by year, the highest was 31.9 ppb, in 2022, above EPA’s legal limit of 30 ppb. Its highest single sample was 45.4 ppb. In 2023, the latest year on file, its one sample was 19 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for uranium at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 20.5 ppb, in 2018.
What handles it
- NSF/ANSI 58 look for “Uranium”
Above the health goal1
Arsenic
Comes from the source
3.0ppb
Highest yearly average, 2021 to 2026
2026: not found
Averaged by year, the highest was 3.0 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2026, the latest year on file, it wasn’t found in its one sample.

2026: not found
Averaged by year, the highest was 7.1 ppb, in 2023, below EPA’s legal limit of 60 ppb. In 2026, the latest year on file, it wasn’t found in its one sample.

Chromium (total)
Comes from the source
5.0ppb
Highest yearly average, 2021 to 2026
2026: not found
Averaged by year, the highest was 5.0 ppb, in 2025, below EPA’s legal limit of 100 ppb. 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 yearly average of 0.5 ppb, in 2018.

- NSF/ANSI 53 look for “Chromium Reduction”
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: Uranium, Arsenic (Pentavalent)<=50 ppb Reduction
For: Uranium, 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. Uranium, arsenic, nitrate, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5) and chromium (total) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Prairie View Ranch WD’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 Dec. 17, 2020 to Sept. 29, 2026.
Testing your own tap
No lab Colorado certifies is within 75 miles of the area Prairie View Ranch WD serves on the state’s list. Some take samples by mail; the state’s page lists them all.
