The short answer
3 results are above the health goal. The worst: Uranium, above the health goal. 6 health-based violations since 2016.
What handles itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 2019 to 2026.
Uranium, arsenic, total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), fluoride and chromium (total): Colorado’s own results, samples taken from Aug. 28, 2020 to July 27, 2026, with EPA’s 2012 to 2019 file for earlier years.

12ppb
Highest yearly average, 2021 to 2025
2025 average: 9.9 ppb
Averaged by year, the highest was 12 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 14 ppb. In 2025, the latest year on file, its three samples averaged 9.9 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 9.4 ppb, in 2016.

2.0ppb
90th percentile, 2026
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.

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
Claims: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction
For: Lead, Arsenic
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Uranium, Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction
For: Uranium, Lead, Arsenic
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)
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. Uranium, arsenic, total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), fluoride and chromium (total) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Mountaindale Cg and Cabins’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 Aug. 28, 2020 to July 27, 2026.
