Arsenic Removal from Drinking Water by Adsorptive Media, U.S. EPA Demonstration Project at Bow, NH. Final Performance Evaluation Report

摘要

This report documents the activities performed during and the results obtained from the U.S. Environmental Protection Agency (EPA) arsenic removal treatment technology demonstration project at the White Rock Water Company (WRWC) public water system, a small residential drinking water facility in Bow, NH. The main objective of the project was to evaluate the effectiveness of the ADI International, Inc. (ADI), located in New Brunswick, Canada, G2 media in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 ig/L. Additionally, this project evaluated: (1) the reliability of the treatment system for use at small water facilities, (2) the required system operation and maintenance (O&M) and operator skill levels, and (3) the capital and O&M cost of the technology. The project also characterized the water in the distribution system and process residuals generated by the treatment system. The types of data collected included system operation, water quality (both across the treatment train and in the distribution system), process residuals, and capital and O&M cost.
