The ZIP code it serves
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 itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 1994 to 2025.
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.6 ppm, for the period ending June 30, 1994. None since is on file, so it is not counted as a current finding.
Arsenic, uranium, fluoride, nitrate, total trihalomethanes (TTHM), chromium (total) and haloacetic acids (HAA5): Colorado’s own results, samples taken from March 23, 2020 to Feb. 4, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the health goal3
Arsenic
Comes from the source
3.5ppb
Highest yearly average, 2023 to 2024
Averaged by year, the highest was 3.5 ppb, in 2024: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 4.0 ppb. That was also the latest year on file.

Lead
Comes from pipes, often your own
4.0ppb
90th percentile, 2025
In the latest period, 9 in 10 homes sampled were at or below 4.0 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: 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, fluoride, nitrate, total trihalomethanes (TTHM), chromium (total) and haloacetic acids (HAA5) results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Soda Springs WA’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 March 23, 2020 to Feb. 4, 2026.
