What this report can’t tell you

  • Everything else. Nitrate, fluoride, arsenic and chromium (total) results here are Wisconsin’s own from 2023 on, with EPA’s national file for 2012 to 2019. Pine Crest Resort 2 - Upper Well’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; Wisconsin’s results run from May 8, 2023 to March 12, 2026.
