What this report can’t tell you
Everything else. Fluoride, total trihalomethanes (TTHM), arsenic, chromium (total), haloacetic acids (HAA5) and nitrate results here are Ohio’s own from 2020 on, with EPA’s national file for 2012 to 2019. Aqua Ohio - la Rue Village PWS’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.
