The short answer

Nothing in EPA’s and California’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

Nitrate, arsenic, chromium (total) and total trihalomethanes (TTHM): California’s own results, samples taken from Feb. 3, 2020 to Feb. 2, 2026, with EPA’s 2012 to 2019 file for earlier years.

Fluoride: EPA’s compliance monitoring file, samples taken from Feb. 2, 2015 to March 5, 2018. Newer results are in the utility’s annual water quality report.

What this report can’t tell you

  • Everything else. Nitrate, arsenic, chromium (total) and total trihalomethanes (TTHM) results here are California’s own from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride comes from EPA’s file alone, which ends in 2019. Womack Subdivision M.W.C.’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; California’s results run from Feb. 3, 2020 to Feb. 2, 2026; EPA’s compliance samples are from Feb. 2, 2015 to March 5, 2018.

Testing your own tap

Womack Subdivision M.W.C.’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 California certifies.
