Preparing Bay City environmental records...
Use EPA’s site search to locate the underlying cleanup record, then review its boundaries, affected environmental media, investigation dates and latest status. A nearby site listing does not establish exposure at an address. Groundwater or surface water findings also do not establish tap water results; those require information about the actual drinking water supply.
Check your water bill for your utility name and confirm the reporting year. See EPA’s guide to finding your annual water quality report.
