The ZIP code it serves
The short answer
1 result is above the health goal. The worst: Uranium, above the health goal. No health-based violations on file since 2016.
What handles itWhat was found
Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and arsenic: Missouri’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.
Uranium, chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from Jan. 17, 2012 to Dec. 9, 2019. Newer results are in the utility’s annual water quality report.
Above the health goal1
Uranium
Comes from the source
1.8ppb
Highest yearly average, 2012 to 2013
2013: not found
Averaged by year, the highest was 1.8 ppb, in 2012: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 3.9 ppb. In 2013, the latest year on file, it wasn’t found in any of its two samples.
What handles it
- NSF/ANSI 58 look for “Uranium”
Below EPA’s limits3

2023 average: 10.9 ppb
Averaged by year, the highest was 22.9 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 10.9 ppb.

- Arsenic
- Chromium (total)
- Fluoride
- Lead
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.”

Claim: Uranium
For: Uranium
At the tap, or for the whole house?
These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.
Filters with those claims on a certifier’s listing
None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and arsenic results here are Missouri’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Uranium, chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. MO American Stonebridge Village’s own annual report, which it must send you every year, has newer results for those and 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; CDC’s yearly averages for Missouri cover 2020 to 2023; EPA’s compliance samples are from Jan. 17, 2012 to Dec. 9, 2019.
