The short answer

1 result is above the health goal. The worst: Lead, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2019 to 2025.

Fluoride, haloacetic acids (HAA5), total trihalomethanes (TTHM), chromium (total), arsenic, nitrate and uranium: Colorado’s own results, samples taken from Feb. 10, 2020 to July 21, 2026, with EPA’s 2012 to 2019 file for earlier years.

  • Nitrate
  • Uranium

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.”

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. Fluoride, haloacetic acids (HAA5), total trihalomethanes (TTHM), chromium (total), arsenic, nitrate and uranium results here are Colorado’s own from 2020 on, with EPA’s national file for 2012 to 2019. Sierra Vista HOA’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 Feb. 10, 2020 to July 21, 2026.

Testing your own tap

Sierra Vista HOA’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.
