What this report can’t tell you

Everything else. Fluoride, chromium (total), total trihalomethanes (TTHM), arsenic, haloacetic acids (HAA5), nitrate and uranium results here are Colorado’s own from 2022 on, with EPA’s national file for 2012 to 2019. Foxhill MD’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 1, 2022 to Jan. 13, 2026.

Testing your own tap

Foxhill MD’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.
