Systems ranked by number of samples detected above the minimum reporting limit. Detection count reflects monitoring frequency, not concentration level.
All records are from official EPA UCMR 5 monitoring data. Detection counts reflect the number of samples where the analyte was reported above the minimum reporting limit (MRL). They are not compliance determinations and do not imply a health violation.
