The short answer

2 results are 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, uranium, fluoride, nitrate, chromium (total), haloacetic acids (HAA5) and total trihalomethanes (TTHM): Colorado’s own results, samples taken from Feb. 12, 2020 to Feb. 3, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

2.0ppb

Highest yearly average, 2020

Averaged by year, the highest was 2.0 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 2013.

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

2.7ppb

Highest yearly average, 2025

Averaged by year, the highest was 2.7 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 13 ppb, in 2014.

What handles it

Below EPA’s limits4

Fluoride

Forms or is added in treatment

Below EPA’s limits

1.4ppm

Highest yearly average, 2020 to 2025

2025, one sample: 1.3 ppm

Averaged by year, the highest was 1.4 ppm, in 2020, below EPA’s legal limit of 4.0 ppm. In 2025, the latest year on file, its one sample was 1.3 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.7 ppm, in 2013.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

2.6ppm

Highest sample; found in 7 of 7

2026, one sample: 0.4 ppm

The highest sample, in 2023, was 2.6 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 0.4 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 3.4 ppm, in 2012.

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

2.0ppb

Highest yearly average, 2020

Averaged by year, the highest was 2.0 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 3.0 ppb, in 2013.

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

1.1ppb

Highest yearly average, 2021 to 2024

2024: not found

Averaged by year, the highest was 1.1 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2024, the latest year on file, it wasn’t found in its one sample.

What handles it

No certification claim covers this compound yet.

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Lead
  • Total trihalomethanes (TTHM)

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.

Hardness

Moderately hard, typically 69 mg/L (4 grains per gallon), across 2 sampling points, in 2025.

Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

Violations since 2016

No health-based violations on file with EPA since 2016. There are 6 monitoring or reporting violations: a sample missed, late or not reported.

What this report can’t tell you

  • Everything else. Arsenic, uranium, fluoride, nitrate, chromium (total), haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Mountain View Village East’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 Feb. 12, 2020 to Feb. 3, 2026.

Testing your own tap

Mountain View Village East’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.
