United States Office of Water (WH 550G) EPA 570/9-91-036J Environmental Protection January 1992 Agency SERA Best Management Practices For Protecting Ground Water For Medical Services Facilities Using Shallow Industrial Waste Disposal Wells (Class V Well BMP Fact Sheet Number 2H) EPA recognizes that oertain Industrial waste disposal practices using drainage wells may pose unacceptable risks to Underground Sources ot Drinking Water These operations aliow the discharge of Various wastes to a drainage system neither designed for nor capable of treating them Accordingly, BMPs for industrial Disposal Wells focus on well closure and alternative disposal methods We have also included BMPs for waste minimization to help facilities reduoe waste disposal costs, regardless of the disposal method they use In addition local, county, and State regulations may prohibit use of these wells Note these practices are recommendations only For more information, contact the person named below The BMPs listed below apply to medical services facilities. Fact Sheet Number 2 in this series lists BMPs that are applicable to Industrial Disposal Wells in general (including those used by medical services facilities), particularly for closure and alternative disposal. Waste Minimization • Install water demand zone valves to control water use * Use reverse osmosis water supply equipment, where technically feasible, to minimize cleaning requirements tor dialysis machines ~ Use a closed-cycle system to enhance recovery of silver * Renew photoprocessing chemicals using replenisher concentrates and regen- erators * Recycle developer using, for example, an ion exchange system or an electrodi- alysis system • Recover silver from photographic equipment using metallic replacement, electrolytic recovery, chemical precipitation, ion exchange, reverse osmosis, and/or evaporation • Replace instruments containing mercury with electronic instruments • Segregate and properly label radioactive wastes * Use less hazardous isotypes where possible; for example, use iridium-192 or cesium-137 needles in place of radium-226 needles ------- |
