The short answer
Nothing in EPA’s and Colorado’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. No health-based violations on file since 2016.
What was found
Fluoride, total trihalomethanes (TTHM), chromium (total), arsenic, haloacetic acids (HAA5), nitrate and uranium: Colorado’s own results, samples taken from March 5, 2020 to Aug. 24, 2026, with EPA’s 2012 to 2019 file for earlier years.

- Arsenic
- Haloacetic acids (HAA5)
- Lead
- Nitrate
- Uranium
Hardness
Soft, typically 19 mg/L (1.1 grains per gallon), across 2 sampling points, in 2024.
Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.
Violations since 2016
No health-based violations on file with EPA since 2016.
What this report can’t tell you
Everything else. Fluoride, total trihalomethanes (TTHM), chromium (total), arsenic, haloacetic acids (HAA5), nitrate and uranium results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Inspiration Valley MHP’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 5, 2020 to Aug. 24, 2026.
