MD SB930

Establishes the Managed Aquifer Recharge Pilot Program within the Department of the Environment to authorize, regulate, and evaluate injecting treated reclaimed water into aquifers to address groundwater supply problems such as land subsidence or saltwater intrusion anticipated within the next 25 years.

Prohibits groundwater augmentation except through a permit issued under this program, with the Department limited to issuing only one permit; applications accepted from January 2, 2026 through January 3, 2028.

Requires treated reclaimed water to meet primary and secondary maximum contaminant levels, achieve pathogen reductions of 12-log for enteric viruses and 10-log for Giardia and Cryptosporidium, and for confined aquifers, undergo reverse osmosis treatment with total organic carbon not exceeding 0.5 milligrams per liter.

Mandates applicants complete hydrogeological investigations, identify all wells within 2 years of water travel time, submit mitigation plans including alternative drinking water sources for affected well users, and install monitoring wells 14-180 days downgradient from injection sites.

Permits are valid for 5 years with possible 5-year renewals; the Department must report annually to the Governor and General Assembly starting December 31, 2028; the entire act sunsets on September 30, 2036.
