Idaho

Idaho drinking water compliance.

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

Who regulates water systems in Idaho

Idaho'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 Idaho systems alongside state rules.

What Idaho 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
