Document Description
Water quality samples collected from Well Nos. 4 and 5 indicate the presence of arsenic at concentrations above the new Federal MCL of 10 µg/l, which took effect on January 23, 2006. Recent water samples from Well Nos. 4 and 5 contained arsenic at 39 µg/l and 41 µg/l, respectively. In order to address the new Federal arsenic limits, the District proposes to install a wellhead treatment unit for both wells.
