Description:
This paper is a summary of two EPA reports prepared by Battelle Memorial Institute: "Arsenic Removal from Drinking Water by Coagulation/Filtration and Lime Softening" and "Arsenic Removal from Drinking Water by Iron Removal Plants." The paper presents the results of a year long study consisting of weekly sampling and analysis of five water treatment plants in the USA removing arsenic. The plants consisted of two coagulation/filtration plants, two iron removal plants and one lime softening plants. The study was conducted to evaluate the performance of these full scale plants for consistently removing arsenic from raw water containing from 2.6 to 97.9 ug/L of total arsenic. The two coagulation/filtration plants and one iron removal plant consistenly removed the arsenic below 10 ug/L while the other iron removal plant and the lime softening plant did not.
