Arsenic: USGS maps show naturally occurring arsenic in groundwater in parts of Indiana and its region. Test at least once, then as your lab or health department advises. Source
PFAS: test if you live near an airport, military base, landfill, or industrial or firefighting-foam site. EPA explains private well PFAS testing. Source
After flooding, test for bacteria before drinking the water again, as EPA advises. Source
