Comparison: State vs. Federal
• Rules. Unlike the federal rules, New Hampshire prohibits the underground injection of hazardous waste but has otherwise adopted the federal underground injection regulations. The state does allow underground injection into wells of fluids other than wastewater, such as aquifer recharge and heat pump discharge and regulates these through the groundwater protection regulations. Such wells must be registered with DES. See the national section UNDERGROUND INJECTION WELLS for more information.
• Administration and enforcement. The DES Hazardous Waste Compliance Section/RCRA enforces the hazardous waste disposal prohibition in New Hampshire. DES's Water Division administers and enforces underground injection registration in the state. EPA Region 1 office works with state, tribal, and local governments to support their management of injection wells in order to prevent contamination of drinking water resources.
