SACRAMENTO, Calif. (AP) - University of California, Davis officials are investigating the source of high levels of Chromium-6, or hexavalent chromium, recorded at the site of its former animal testing lab.

The Sacramento Bee reports (https://bit.ly/1PZuaQm) standards adopted in 2014 for chromium-6 levels have put several wells in Davis over the limit for the carcinogen, including 42 of 100 monitoring wells at the Laboratory for Energy-Related Health Research.

UC Davis environmental manager Sue Fields says the presence of the carcinogen is a conundrum at a site where experiments never included chromium.

The university is treating water from wells at the site, converting chromium-6 to naturally occurring chromium-3. Fields and Stanford University expert Scott Fendorf are looking at causes for the rising levels, hoping to shed light on the region-wide presence of the toxic metal.
