Third Bullet Item, Second Paragraph <br /> Excavation to the north and west of the property was not possible due to the presence of <br /> underground utilities and pipelines immediately adjacent to the property boundaries. In addition, <br /> continued excavation to the north would have jeopardized the integrity of Grantline Road. <br /> Excavation to the south was not warranted due to the lack of detectable hydrocarbons beyond <br /> the excavation limits. Finally, excavation beyond the eastern property boundary was not <br /> justified based on field and analytical data. <br /> Section 1.2,6, Page 1-5 <br /> The intent of the information summary is to provide an overview of the site characterization as <br /> it currently exists. Site data collected in 1986 was not included because it involved <br /> characterization of the site as it existed prior to soil excavation. Therefore, data collected in <br /> 1986 does not reflect the current conditions of the site and was excluded on that basis. <br /> Section 1.2.6.1, Pages 1-6 and 1-7 <br /> First Bullet Item <br /> The data presented in this section of the document was not misleading; it describes the analytical <br /> results for soil samples obtained during previous activities conducted on the site. Additional <br /> information regarding the distribution and types of contaminants detected in subsurface soil is <br /> presented elsewhere in the report. <br /> Second Bullet Item <br /> The soil sample referred to was collected at or below the capillary fringe or ground water table. <br /> In accordance with standard practice of industry, soil samples collected from below ground water <br /> were not analyzed since hydrocarbons present in the saturated zone are considered to be in the <br /> dissolved-phase. Water samples from AW-9 have been analyzed at regular intervals since April <br /> 1992, and at the last sampling, no detectable concentrations of analytes were present in the <br /> samples from AW-9. <br /> Third Bullet Item <br /> While Geomatrix states that data from Monitoring Wells AW-10, AW-11, and AW-12 were not <br /> presented in the text of the risk assessment, the risk assessment does state "Detectable <br /> concentrations of TPH-G, TPH D, and BTEX were observed in soil samples from AW-10, AW- <br /> 11, and AW-12. A comprehensive summary of the analytical results for soil is presented in <br /> Table 1-2. " The information is presented in tabular form to facilitate data analysis and review. <br /> 5 <br />
