Title 23 of the California Code of Regulations Section 2672(e) requires that the detection of any reportable unauthorized release during a permanent closure proceeding for underground storage tanks shall require compliance with the applicable corrective action requirements of 23 Cal. Code Reg. Sections 2720 et seq. A Soil and Water Investigation includes the collection and analysis of data necessary to assess the nature of the vertical and lateral extent of the unauthorized release (23 Cal. Code Reg. Section 2725(a)).

This treatise provides evidence of groundwater contamination resulting from a leakage of petroleum hydrocarbon from an underground storage tank into soil. This treatise reports and summarizes the results of Quantitative Gas Chromatography/Mass Spectrometry Analysis of three (3) soil samples and three (3) groundwater samples obtained from borings drilled in specified locations in proximity to the location of a former pit that had accomodated two underground gasoline storage tanks. The vertical and lateral extent of contamination resulting from an unauthorized release of gasoline is characterized by analytical results including concentration estimates for Gasoline Range Organics (C4-C10) and Benzene, Toluene, Ethylbenzene, Xylene, Methyl Tert Butyl Ether and Tertiary Butyl Alcohol.
