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: Total trihalomethanes (TTHM), above the limit’s level, no violation. 1 health-based violation since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2004 to 2025.

Total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate, arsenic and chromium (total): Colorado’s own results, samples taken from July 21, 2020 to Aug. 17, 2026, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from Oct. 15, 2012 to Oct. 15, 2012. Newer results are in the utility’s annual water quality report.

Above the limit’s level, no violation

123ppb

Highest yearly average, 2020 to 2024

2024: not found

Averaged by year, the highest was 123 ppb, in 2022, above EPA’s legal limit of 80 ppb. In 2024, the latest year on file, it wasn’t found in any of its three samples. EPA judges this limit on running averages at each sampling point, and recorded no violation for total trihalomethanes (TTHM) 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 77.6 ppb, in 2016.

Above the health goal

2.0ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 2.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

2025, one sample: 2.8 ppm

Averaged by year, the highest was 3.0 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. In 2025, the latest year on file, its one sample was 2.8 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.1 ppm, in 2016.

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.”

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

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. Total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), nitrate, arsenic and chromium (total) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Uranium comes from EPA’s file alone, which ends in 2019. View Ridge Mutual WC’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; Colorado’s results run from July 21, 2020 to Aug. 17, 2026; EPA’s compliance samples are from Oct. 15, 2012 to Oct. 15, 2012.

Testing your own tap

View Ridge Mutual WC’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.
