Where can I find information on water quality criteria or standards?

The Office of Science and Technology (OST) within the Office of Water is the best source to help with water inquiries. This office not only offers information about water quality criteria, water standards, and laws and regulationsIt also access to water quality tools, health advisories, industrial water pollution controls, training and financial assistance.

The National Water Quality Standards Database (WQSDB) provides access to EPA and state water quality standards (WQS) information in text, tables, and maps.

The National Recommended Water Quality Criteria presents a summary table containing recommended water quality criteria for the protection of aquatic life and human health in surface water for approximately 150 pollutants. 

Another resource of information is the Safewater Q&A Database.

If you have questions about Water Quality Standards, please contact the Standards and Health Protection Division.
