PROJECT TITLE: Sunset Reservoir Ion
Exchange Project
PROJECT ADDRESS: 201 W. Mountain St.
Case Manager:
Adolfo Vargas
PROJECT
DESCRIPTION:
The proposed project
includes installation of an ion exchange perchlorate treatment
system (Ion Exchange system), a booster pump station, a
chloramination system, and piping at the City’s Sunset Reservoir
site. A preliminary site layout is shown as Figure 4 and Figure 5
is a flow diagram of the proposed treatment plant. The proposed Ion
Exchange system will be designed to remove perchlorate contamination
from groundwater produced from either the Copelin and Sunset Wells
or the Bangham Well by itself. Ion Exchange treatment technology is
a proven and accepted method of removing perchlorate. Currently,
average perchlorate concentrations at the Copelin and Sunset Wells
are approximately 18.5 micrograms per liter (ug/L) and 16.4 ug/L,
respectively. These perchlorate concentrations exceed the
California Department of Health Services’ (CDHS) Notification Level
for perchlorate of 6 ug/L.
