Th e facility consists of a closed Class I hazardous waste landfi ll and an inactive Class III municipal solid waste Maintenance, and System landfi ll. Between November 2004 and March 2007, ERRG operated Optimization and maintained the following critical facility systems: • Landfi ll gas collection/migration control systems. • Landfi ll gas combustion system. SUMMARY • Landfi ll cover and irrigation systems. • Groundwater and leachate extraction Owner State of California, Dept. of Toxic systems. Substances Control (DTSC) • On-site leachate treatment plant Location (LTP) Air, soil gas, West Covina, CA and groundwater monitoring network.

Copper was mined from the Aqua Zarco Sandstone at the Nacimiento Copper Mine using a number of shallow shafts and adits from 1880 to 1970. From 1970 to 1984, copper ores were mined from SUMMARY an open pit which resulted in the topography currently present at the site. From 1984 to 2000, in-situ leaching was pilot tested to recover copper. Th e acids injected during the pilot testing contaminated the groundwater, and it is this groundwater contamination that was the Owner target of this remedial action. U.S. Forest Service Th e groundwater was heavily laden Location with metals (aluminum, copper, Nacimiento Copper Mine iron, magnesium, zinc), and had Santa Fe National Forest, New Mexico an average pH of 3.59. Geologic conditions beneath the site limited Award Date ground water migration. Th e June 2007 extraction system constructed includes nine extraction wells, Actual Completion Date November 2008 located in the bottom of the open mine pit. Th ese wells penetrate Award Amount through the Aqua Zarco Sandstone $2,668,000 at depths between 250 and 450 feet below ground surface. Th e Final Contract Price nine wells are expected to extract a combined volume of 120 gallons $2,668,000 per minute over the four year operational life of the system. Extracted groundwater is pumped to a pair of collection tanks before being Services Provided pumped out of the mine pit to the treatment system. Construction of a Bioreactor System Start-up and O&M Th e groundwater treatment system is a semi-passive alcohol enhanced bioreactor system. Th e system includes a large settling basin (850,000 gallon capacity) within which sodium hydroxide is metered into the extracted groundwater to neutralize the pH and precipitate some of the metals. Ground water passes into a large cobble fi lled bioreactor (300,000 gallon capacity) within which ethanol is metered into the water to provide nutrients for the naturally occurring bacteria which extracts the remaining metals. Th e treated groundwater is discharged to a nearby stream, which was modifi ed to handle the signifi cantly increased fl ow that results from the treatment system.

Th e contract was designed to assist the DTSC in meeting its commitment of reducing the risk of released hazardous substances/ materials to public health and to the environment in an eff ective and SUMMARY expeditious manner. Under this contract ERRG was tasked with implementation of remedial actions necessary to prevent, mitigate, or eliminate the release of uncontrolled hazardous substances/materials at sites in California. ERRG has conducted Owner work on 17 task orders totaling $13.6M State of California over the life of this contract. Dept. of Toxic Substances Control (DTSC) ERRG worked closely with DTSC personnel to select appropriate remedies and Location provide fi nal documentation for site closure. San Leandro, CA Highlights from the Singer-Friden task order are discussed below.
