For the first time, a Glendale research team testing methods for stripping chromium 6 from groundwater has released an estimate for how much it will cost long term — putting the tab at up to $27 million over 20 years.
The costs will be a key consideration for the California Department of Public Health, which plans to use the more than 10 years of research carried out by Glendale Water & Power to set a new maximum contaminant level for cancer-causing hexavalent chromium.
In doing so, state officials must consider the costs and technical feasibility.
“The costs are something new. It’s the first time they’ve seen that,” said Leighton Fong, a civil engineer and project manager for the research.
Although the state Department of Public Health has reviewed the report, they would not comment on the initial cost estimates because they had not completed a cost benefit analysis, spokesman Ronald Owens said.
