What was found

Lead and copper: EPA SDWIS monitoring periods ending 2002 to 2023.

Nitrate: Iowa’s own results, samples taken from May 6, 2020 to April 8, 2026.

Fluoride, arsenic and chromium (total): EPA’s compliance monitoring file, samples taken from Oct. 29, 2019 to Oct. 29, 2019. Newer results are in the utility’s annual water quality report.

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. Nitrate results here are Iowa’s own from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride, arsenic and chromium (total) come from EPA’s file alone, which ends in 2019. Stoney Creek Subdivision’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; Iowa’s results run from May 6, 2020 to April 8, 2026; EPA’s compliance samples are from Oct. 29, 2019 to Oct. 29, 2019.

Testing your own tap

Stoney Creek Subdivision’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 Iowa certifies.
