The ZIP code it serves
The short answer
2 results are above EPA’s legal limit, and 2 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 27 health-based violations since 2016.
What handles itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 2011 to 2025.
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 3.3 ppm, for the period ending Dec. 31, 2003. None since is on file, so it is not counted as a current finding.
Total trihalomethanes (TTHM), haloacetic acids (HAA5), uranium, fluoride, nitrate, chromium (total) and arsenic: Colorado’s own results, samples taken from Feb. 18, 2020 to Aug. 11, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit2
Total trihalomethanes (TTHM)
Forms or is added in treatment
164ppb
Highest yearly average, 2020 to 2026
2026 average: 90.1 ppb
Averaged by year, the highest was 164 ppb, in 2025, about twice EPA’s legal limit of 80 ppb. Its highest single sample was 352 ppb. In 2026, the latest year on file, its three samples averaged 90.1 ppb, above the limit. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2023, 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 55.6 ppb, in 2013.

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: Trihalomethanes (TTHM) Reduction, Lead Reduction
For: Total trihalomethanes (TTHM), Lead
Other certifiers’ wording: VOC Reduction
- NSF/ANSI 58
Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction, Uranium
For: Total trihalomethanes (TTHM), Lead, Uranium
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), haloacetic acids (HAA5), uranium, fluoride, nitrate, chromium (total) and arsenic results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Pinewood Springs 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 Feb. 18, 2020 to Aug. 11, 2026.
