The Jibboom Junkyard site is located on the east bank of the Sacramento River, approximately 6,000 feet from the State Capital Building. The nine acre site is the former location of the Associated Metals Company salvage yard. Today, a majority of the site, 6.7 acres, is covered by Interstate 5 and the adjacent Jibboom Street. The property was used for a metal salvage operation until 1965. All grades of metal were salvaged, including railroad cars, army tanks, batteries, and some transformers. Results of the seven EPA and DOHS sampling efforts indicate that there is extensive lead, zinc, and copper contamination onsite. Most of the contamination is limited to the top one foot of soil, and no offsite contamination has been detected. Subsurface contamination above background levels was only detected at four locations. The selected remedy for the Jibboom Junkyard consists of excavation and removal of contaminated soils to a RCRA-approved offsite, Class 1, hazardous waste disposal facility. The total capital cost of the selected remedial alternative is estimated to be $1,460,000.
