The short answer

3 results are above the health goal. The worst: Arsenic, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2023.

Arsenic, uranium, nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride and chromium (total): Colorado’s own results, samples taken from April 8, 2020 to Sept. 28, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal3

Arsenic

Comes from the source

Above the health goal

6.0ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 6.0 ppb, in 2025: below EPA’s legal limit of 10 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 6.0 ppb, in 2019.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Lead

Comes from pipes, often your own

Above the health goal

3.0ppb

90th percentile, 2023

In the latest period, 9 in 10 homes sampled were at or below 3.0 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

Uranium

Comes from the source

Above the health goal

2.0ppb

Highest yearly average, 2022

Averaged by year, the highest was 2.0 ppb, in 2022: 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 2.0 ppb, in 2016.

What handles it

Below EPA’s limits5

Nitrate

Comes from the source

Below EPA’s limits

4.2ppm

Highest sample; found in 6 of 6

2025, one sample: 3.8 ppm

The highest sample, in 2020, was 4.2 ppm, below EPA’s legal limit of 10 ppm. In 2025, the latest year on file, its one sample was 3.8 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 3.7 ppm, in 2019.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

19.9ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 19.9 ppb, in 2026, below EPA’s legal limit of 80 ppb. Its highest single sample was 30.4 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 31.6 ppb, in 2018.

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

11ppb

Highest yearly average, 2020 to 2026

2026 average: 9.1 ppb

Averaged by year, the highest was 11 ppb, in 2021, below EPA’s legal limit of 60 ppb. Its highest single sample was 13.2 ppb. In 2026, the latest year on file, its two samples averaged 9.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.9 ppb, in 2018.

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.3ppm

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 0.3 ppm, in 2025, 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 0.33 ppm, in 2013.

What handles it

Chromium (total)

3.0ppb

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 3.0 ppb, in 2025, below EPA’s legal limit of 100 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.0 ppb, 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.”

  • NSF/ANSI 53

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Arsenic, Lead

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction, Uranium

    For: Arsenic, Lead, Uranium

    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. Arsenic, uranium, nitrate, total trihalomethanes (TTHM), 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. Kiowa Water and Wastewater Authority’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 April 8, 2020 to Sept. 28, 2026.

Testing your own tap

Kiowa Water and Wastewater Authority’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.
