Scenario 1The bill names the research starting point
When the current bill identifies City of Batesville, use that exact system to locate the newest report. Compare the source description—Municipal wells—with the report before carrying any value into a treatment decision.
Scenario 4The building has its own plumbing history
Even when the public-system report is correct, service lines, premise plumbing, water heaters and vacant-building conditions can create address-level questions. Separate system compliance from what a sample at the building can establish.
Scenario 3The property uses a private well or the source is unknown
Do not borrow the public-system contaminant table for a private well. Document the well, treatment equipment, service history and plumbing, then use a certified laboratory panel selected for the actual source and concern.
Scenario 2The ZIP code and supplier do not line up neatly
An address using ZIP 47006 may still sit near a utility boundary, purchased-water zone or private-well area. The postal code organizes mail; it does not prove that City of Batesville supplies the property.
Local research context: The regional context is Cincinnati Metro and Southeast Indiana, while the city inventory places Batesville in Ripley and Franklin County. Neither label substitutes for the supplier name on the bill.
Current city note: The city crosses county lines; utility data should be tied to the account, not county alone.
