Water Quality in Indiana

The Office of Water Quality’s (OWQ) mission is to monitor, protect, and improve Indiana’s water quality to ensure its continued use as a drinking water source, habitat for wildlife, recreational resource and economic asset.

The office achieves this by: developing rules, guidance, policies and procedures; assessing surface and ground water quality; regulating and monitoring drinking water supplies and waste water facilities; protecting watersheds and wetlands and providing outreach and assistance to the regulated community and the public while supporting environmentally-responsible economic development. Indiana's Water Quality Standards as mandated by the Clean Water Act are the measure used for these activities. OWQ's Featured Topics page highlights information about regulations and issues with wide public interest.

More information is available from the Office of Water Quality Contacts and the Nonpoint Source Program Contacts lists.
