Glendale Water & Power has started testing a new filtration method to strip chromium 6 from groundwater and plans to start the process for other techniques next month. Previous methods have had some drawbacks, prompting the fresh approaches.
Filtration adds an extra step to current testing, but the others, which include using resins and absorption technology to suck out the cancer-causing contaminant, are new ventures.
“We’re blazing the trail here,” said Charles Cron, plant manager at a chromium 6 testing facility in northwest Glendale.
The new research is part of a $550,000 project approved by the City Council in October. The money comes from a state grant, the Denver-based Water Research Foundation and California Water Service Co., a San Jose-based utility.
Glendale and other cities throughout the San Fernando Valley have been grappling with chromium 6 contamination caused by the aerospace manufacturing industry decades ago. Glendale has spent more than $8 million, including this new project, on chromium 6 research. Much of the money has come from grants.
