Groundwater Wellhead Treatment System Project
Since the discovery of the contaminant perchlorate in the Rialto-Colton groundwater basin in 2000, the public has become increasingly concerned of its effects on the community. In April 2002, the State of California Department of Public Health Services issued a Conditional Acceptance of “biological treatment as a means of removing perchlorate from source waters for distribution as a part of the public water supply.” West Valley Water District has teamed up with the City of Rialto to construct a “bioremediation” wellhead treatment system that would help stabilize water supplies in the Rialto-Colton groundwater basin.
