Bunker C fuel is technically any type of fuel oil used aboard ships or trains, getting its name from the containers on ships and in ports that it is stored in. Bunker C fuel oil is a high-viscosity residual oil that requires pre- heating before the oil can be pumped from a bunker tank. “Residual” refers to the material remaining after the more valuable cuts of crude oil have boiled off. The residue used for Bunker C fuel may contain various undesirable impurities including 2 percent water and one-half percent mineral soil that are undesirable in an oil product.

A leachate seep collection and transmission system (LSCTS) was installed by the landowner as part of a leachate management system to meet the interim objective required by the Regional Water Quality Control Board. The system is located at the southern end of the Brisbane Landfill, intercepting leachate and conveying it to the Bayshore Sanitary District sewer line. Results from the summer 2010 monitoring event indicated that no leachate seeps were observed; therefore, the leachate seep collection and transmission system is operating as designed, and no exposure to human or environmental receptors is occurring (Geosyntec, 2010). Table 4.G-2 presents the maximum reported concentrations of chemical compounds in the leachate wells. Those chemical compounds not included in this table were not detected above the laboratory reporting limits. The Maximum Contaminant Level for California drinking water is provided for context, but it should be noted that groundwater is not used for domestic water supply in Brisbane, and thus cleanup levels ultimately approved by the Regional Water Quality Control Board may not reflect drinking water standards.

The Groundwater contamination the Brisbane portion of OU-1 largely originated from the San Francisco portion of OU-1 (Schlage Lock property) north of the Project Site consists of soil and groundwater impacted by VOCs that underlie a portion of OU-1. The Brisbane (Project Site) portion of OU-1 contains soil and groundwater impacted by contaminants of concern other than VOCs, including arsenic, lead, cadmium, and mercury in the soil, and nickel, total chromium, and hexavalent chromium in groundwater. Groundwater contamination within the Brisbane portion of OU-1 largely originated from the San Francisco portion of OU-1 (Schlage Lock property).
