Notes: Analytes detected above laboratory detection limits are shown in bold font. All well water samples were collected through well pump or via bailer. Duplicate sample results are shown in parentheses next to well sample results. January data represents re-test data. Maximum contaminant level (MCL) listed in italics. NA indicates no MCL at this time.
