The WQA is empowered by the State of California to protect and promote the beneficial use of groundwater supplies in the San Gabriel Valley.
The WQA was created by the State to address the problem of groundwater contamination in the San Gabriel Valley, in part by coordinating the plans and activities of state and federal agencies and others involved in the cleanup.
The WQA is empowered by the State to address the problem of the migration of contaminated groundwater within the San Gabriel Basin and, in particular, the migration of contaminated water through the Whittier Narrows into the Central Basin.
Since the WQA's inception in 1993, its projects have been responsible for removing nearly 10 tons of contaminants from the San Gabriel Valley groundwater basin.
WQA projects have been responsible for removing more than 50 percent of the total contaminants removed from the basin since the contamination was discovered in 1979.
The WQA currently operates the only groundwater cleanup projects in the San Gabriel Valley that are actively intercepting contaminated groundwater flowing toward the Whittier narrows.
WQA assessments to accomplish cleanup of the San Gabriel Basin have averaged $7.25 per household per year.
