Nothing in EPA’s and Washington’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 1 health-based violation since 2016.

What was found

None of the contaminants in the records below were found at or above the reporting levels.

5 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.

  • Chromium (total)
  • Fluoride
  • Lead
  • Nitrate

Hardness

Soft, 46 mg/L (2.7 grains per gallon), at its one sampling point, in 2025.

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.

What this report can’t tell you

  • Everything else. Arsenic, chromium (total), fluoride and nitrate results here are Washington’s own from 2020 on, with EPA’s national file for 2012 to 2019. Clifton Beach Tracts Co Op’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; Washington’s results run from June 3, 2020 to Aug. 20, 2026.

Testing your own tap

Clifton Beach Tracts Co Op’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 Washington certifies.
