Water Quality Standards Advisory Committee

Water quality standards are used to protect the state’s surface waters. Standards consist of three parts: designated uses, such as fishing or swimming; numerical or narrative criteria to protect the designated uses; and an antidegradation policy, which maintains existing high quality water that exceeds the criteria. Criteria are established by statute and by administrative rules.

The Water Quality Standards Advisory Committee (WQSAC) exists to facilitate public input, solicit advice and provide a forum for the discussion of focused surface water quality standards issues. You can review the committee’s plans and publications below:

• Plan to Generate PFAS Surface Water Quality Standards.
• Assessment of Chlorophyll-a and Phosphorus in New Hampshire Lakes for Nutrient Criteria Development (January 2009).
• Numeric Nutrient Criteria for the Great Bay Estuary (June 2009).
• Joint Report of Peer Review Panel for Numeric Nutrient Criteria for the Great Bay Estuary (February 13, 2014).
• Independent Peer Review of Nutrient Criteria Proposal for the Great Bay Estuary.
