Indiana drinking water compliance.

Public water systems in Indiana must meet both federal Safe Drinking Water Act requirements and Indiana's state drinking water program requirements.

Who regulates water systems in Indiana

Indiana's state primacy agency administers the drinking water program under EPA oversight. Orevant tracks both the federal baseline and state-specific requirements.

Federal baseline requirements — coliform monitoring, lead and copper, disinfection byproducts, Consumer Confidence Reports, PFAS, and lead service line inventories — apply to Indiana systems alongside state rules.

What Indiana systems typically track

  • Routine coliform sampling on a state-approved siting plan
  • Lead and copper tap sampling and service line inventory updates
  • Consumer Confidence Report delivery (community systems)
  • Operator certification renewals
  • PFAS monitoring under the 2024 federal rule
  • Sanitary survey corrective actions
