Arsenic Removal from Drinking Water by Adsorptive Media. USEPA Demonstration Project at Hot Springs Mobile Home Park in Willard, Utah. Final Performance Evaluation Report

摘要

This report documents activities performed for and results obtained from the arsenic removal treatment technology demonstration project at the Hot Springs Mobile Home Park (HSMHP) in Willard, UT. The objectives of the project were to evaluate the effectiveness of Adsorbsia GTO adsorptive media combined with Birm/Filox oxidizing media (as a pretreatment) in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 ug/L. Additionally, this project evaluated (1) the reliability of the treatment system, (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 produced by the treatment process.
