The ZIP code it serves
The short answer
1 result is above the health goal. The worst: Uranium, above the health goal. 27 health-based violations since 2016.
What handles itWhat was found
Uranium, nitrate and arsenic: Missouri’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2021 to 2023.
Above the health goal1
Uranium
Comes from the source
0.43ppb
Highest yearly average, 2021 to 2023
2023: not found
Averaged by year, the highest was 0.43 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2023, the latest year on file, it wasn’t found.
What handles it
- NSF/ANSI 58 look for “Uranium”
Below EPA’s limits1
Nitrate
Comes from the source
0.88ppm
Highest yearly average, 2021 to 2023
Averaged by year, the highest was 0.88 ppm, in 2023, below EPA’s legal limit of 10 ppm. That was also the latest year on file.
What handles it
- NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
- NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
- Arsenic
- 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.”
- NSF/ANSI 58
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. Uranium, nitrate and arsenic results here are Missouri’s yearly averages as CDC publishes them, from 2021 on, with EPA’s national file for 2012 to 2019. Clubb Villa Senior Living’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; CDC’s yearly averages for Missouri cover 2021 to 2023.
