Laboratory for Energy-Related Health Research
The UC Davis Laboratory for Energy-Related Health Research
(LEHR) engaged in studies on the biological effects of bone seeking radionuclides (strontium-90 and radium-226) in lab animals (beagles) from 1960 to 1989.
During the 29 years of operations, LEHR generated and disposed of radioactive, biologic, and chemical wastes, as well as municipal and lab wastes. Dogs were buried onsite in the early years. Later the dog carcasses were shipped to Hanford for disposal. Approximately 35,000 gallons of sludge effluent (dog feces) contaminated with strontium-90 was disposed of in underground concrete banks.
The site was also used by the university as a landfill area for residential and laboratory waste disposal from the late 1940s to 1967. The site contains radioactive waste disposal areas for waste generated from campus and LEHR activities. Records indicate that radioactive wastes with long half-lives were buried onsite in trenches and holes. Two separate special liquid radioactive waste treatment and discharge systems were in operation at LEHR: the systems discharged radionuclides to leach fields onsite.
Quarterly sampling by DOE has revealed elevated concentrations of CHLOROFORM, carbon-14, and TRITIUM in five of 23 onsite monitoring wells. There are 19 municipal wells within 4 miles of the site serving approximately 47,500 people. The nearest resident is approximately 0.5 miles from the site and the estimated population within 4 miles is 41,789.
