The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 3 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2025.

Total trihalomethanes (TTHM), uranium, haloacetic acids (HAA5), fluoride, nitrate, arsenic and chromium (total): Colorado’s own results, samples taken from Feb. 10, 2020 to Aug. 9, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the legal limit

70.7ppb

Highest yearly average, 2020 to 2026

2026 average: 47.2 ppb

Averaged by year, the highest was 70.7 ppb, in 2020, below EPA’s legal limit of 80 ppb. Its highest single sample was 123 ppb. In 2026, the latest year on file, its four samples averaged 47.2 ppb. EPA judges this limit at each sampling point, and recorded violations for total trihalomethanes (TTHM) at this utility in 2020 and 2021. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 77.7 ppb, in 2013.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

1.4ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 1.4 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

Uranium

Comes from the source

Above the health goal

2.4ppb

Highest yearly average, 2022 to 2026

Averaged by year, the highest was 2.4 ppb, in 2026: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.1 ppb, in 2019.

What handles it

Below EPA’s limits3

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

28.1ppb

Highest yearly average, 2020 to 2026

2026 average: 23.6 ppb

Averaged by year, the highest was 28.1 ppb, in 2023, below EPA’s legal limit of 60 ppb. Its highest single sample was 69.8 ppb. In 2026, the latest year on file, its three samples averaged 23.6 ppb. EPA recorded no violation for haloacetic acids (HAA5) at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 28.9 ppb, in 2019.

0.25ppm

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 0.25 ppm, in 2026, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.41 ppm, in 2012.

What handles it

Highest sample; found in 5 of 6

2025, one sample: 0.096 ppm

The highest sample, in 2021, was 0.29 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, its one sample was 0.096 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.13 ppm, in 2015.

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

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), uranium, haloacetic acids (HAA5), fluoride, nitrate, arsenic and chromium (total) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Town of Debeque’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. 10, 2020 to Aug. 9, 2026.

Testing your own tap

Town of Debeque’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.
