What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium results here are Florida’s own from 2020 on, with EPA’s national file for 2012 to 2019. Country Oaks Adult MHP’s own annual report, which it must send you every year, has the contaminants this page does not show.
