The short answer

2 results are above the health goal. The worst: Uranium, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

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

Uranium, nitrate, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), arsenic and chromium (total): Colorado’s own results, samples taken from Sept. 21, 2020 to Dec. 22, 2025, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Uranium

Comes from the source

Above the health goal

3.2ppb

Highest yearly average, 2025

Averaged by year, the highest was 3.2 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 3.0 ppb, in 2019.

What handles it

Lead

Comes from pipes, often your own

Above the health goal

1.1ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 1.1 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.

Highest sample; found in 6 of 6

2025, one sample: 3.1 ppm

The highest sample, in 2025, was 3.1 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its one sample was 3.1 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 8.0 ppm, in 2014.

What handles it

Highest yearly average, 2021 to 2024

2024 average: 14.3 ppb

Averaged by year, the highest was 20.9 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2024, the latest year on file, its two samples averaged 14.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 27.2 ppb, in 2014.

Below EPA’s limits

0.28ppm

Highest yearly average, 2022

Averaged by year, the highest was 0.28 ppm, in 2022, below EPA’s legal limit of 4.0 ppm. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.34 ppm, in 2019.

Below EPA’s limits

2.0ppb

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 2.0 ppb, in 2024, below EPA’s legal limit of 60 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 6.2 ppb, in 2014.

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.”

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, nitrate, total trihalomethanes (TTHM), fluoride, haloacetic acids (HAA5), arsenic and chromium (total) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Town of Kim’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 Sept. 21, 2020 to Dec. 22, 2025.

Testing your own tap

Town of Kim’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.

No lab Colorado certifies is within 75 miles of the area Town of Kim serves on the state’s list. Some take samples by mail; the state’s page lists them all.
