Document Description
The proposed project includes the construction and operation of water treatment facilities to achieve compliance with the new chromium-6 regulation that was promulgated by the State of California in July 2014. The Coachella Valley Water District is proposing an ion exchange treatment plant (IXTP) approach for removing chromium-6 from affected drinking water wells. Ion exchange is a water treatment method where one or more undesirable constituents are removed from the water by exchange with another constituent. Two types of IXTPs will be used for the chromium-6 project: Strong Base Anion Exchange (SBA) and Weak Base Anion Exchange (WBA). SBA treatment would be installed at 23 existing well sites located throughout the CVWD service area, and a new Central Resin Regeneration Facility would be constructed for processing the SBA resin collected from each of these sites. WBA treatment is proposed for five wells that occur in two distinct clusters within the CVWD service area. For each of the clusters, raw water would be pumped from each well and conveyed via new pipelines to a new WBA treatment facility.
