ETV Verification Statement For The Para-Flo™ PF60 Model AA08AS With Actiguard AAFS50

Verification testing of the Kinetico Inc. and Alcan Chemicals Para-Flo™ PF60 Model AA08AS with Actiguard AAFS50 arsenic adsorption media filter system was conducted at the Orchard Hills Mobile Home Park (MHP) Water Treatment Plant (WTP) in Carroll Township, Pennsylvania from April 22, 2003 through October 28, 2003. The source water was untreated groundwater from one of the MHP's groundwater supply wells. The source water, with an average total arsenic concentration of 14 µg/L and a pH of 7.6, received no treatment or chemical addition prior to entering the treatment unit. When operated under the manufacturers' specified site conditions at a flow rate of 1.9 gpm ± 0.1 gpm, the Kinetico Inc. and Alcan Chemicals Para-Flo™ PF60 Model AA08AS with Actiguard AAFS50 arsenic adsorptio media filter system removed arsenic from the feed water to less than the detection limit (2 µg/L) for approximately 8,000 bed volumes, to less than 10 µg/L for approximately 25,000 bed volumes, and to less than the predetermined test endpoint (11 µg/L) after approximately 2,350 hours of total equipment operation for a total of approximately 29,000 bed volumes.
