Sorg*, T J. ARSENIC RULE AND GROUND WATER REMOVAL TECHNOLOGIES. Presented at Louisiana WQTC, Baton Rouge, LA, 12/12-13/2000.
Description:
On 6/22/00 EPA published in the federal register a proposed rule to lower the arsenic maximum contaminant level (MCL) from 0.05 to 0.005 mg/L. The proposed rule also identified a number of best available technologies (BAT) and emerging technologies that EPA proposes to be capably of reducing arsenic levels to the new MCL. This presentation consisted of a summary of newly proposed arsenic regulations and a description of the technologies that have the ability to remove arsenic from ground water to the proposed MCL. The technologies that were discussed were ion exchange, activated alumina adsorption, iron media adsorption and iron removal processes. A special emphasis was placed on modifications that can be made to existing iron removal processes to increase arsenic removal.
