Abstract This report documents the activities performed for and the results obtained from the arsenic removal treatment technology demonstration project at Seely-Brown Village in Pomfret, CT. The objectives of the project were to evaluate the effectiveness of ArsenXnp adsorption media in removing arsenic to meet the new arsenic maximum contaminant level (MCL) of 10 micrograms/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. The community water system was supplied by two wells (Wells No. 1 and No. 2). Arsenic concentrations in raw water averaged 25.2 micrograms /L, existing primarily as soluble As(V). Iron and manganese concentrations were mostly low, either below the method detection limit (MDL) of 25 micrograms /L (for iron) or averaging 28.3 micrograms /L or less (for manganese). Elevated particulate iron and manganese (to as high as 1,232 and 709 micrograms /L, respectively) were measured occasionally during the study period, and had to be removed by pre-filters.
