Additional arsenic removal occurred during filtra- tion to achieve the 86% average removal, leaving only 2.4 to 4.2 ug/L in the finished water. Very good correlation with the sorption model proposed by McNeill and Edwards (1997a) was observed. Pre- dicted arsenic removal ranged between 89 and 91%, while actual removals ranged between 82 and 89%.
