Impact/Purpose:
To inform the public.
Description:
As part of the EPA Arsenic Removal Technology Demonstration Program, a 540-gal/min (gpm) ion exchange (IX) system proposed by Kinetico was selected for demonstration at Vale, OR to remove arsenic and nitrate from a groundwater supply to meet their respective maximum contaminant level (MCL) of 10-µg/L and 10-mg/L (as N). This report documents the activities performed and results obtained from a 3.5-year long demonstration study that evaluated the performance of IX technology for arsenic and nitrate removal, determined the required system operation and maintenance (O&M) and operator skills, characterized the residuals produced by the technology, and determined the capital and O&M cost of the technology.
