Dr.John Farr <br /> Farr Associates <br /> June 30, 1997 <br /> Page 2 <br /> potentially diesel impacted soil outside building 17; and a material storage area in and adjacent to <br /> building 17. See Figure 2 for the building locations. <br /> On July 27, 1996, BEM Systems,Inc. (BEM)performed a limited soil sampling and testing in the four <br /> areas outlined in Delta's March 8, 1995 report. This work was performed on behalf of a potential buyer <br /> of the property. A total of 13 soil borings were installed using a hand auger to a depth of eight feet bsg. <br /> Soil samples were screened in the field at two foot intervals from the surface to a depth of eight feet <br /> bsg. Field flame ionization detector(FID)values were not reported. Soil samples were submitted for <br /> laboratory analyses for several analytical parameters. A copy of the tables prepared by BEM outlining <br /> the sample location, sample depth, analyses performed, and analytical results are presented in <br /> Enclosure A. No volatile organic compounds(VOC)were reported exceeding the laboratory's practical <br /> quantification limit(PQL) with the exception of methylene chloride. Based on the reported compound <br /> and the concentrations, (0.016 to 0.019 milligrams per kilogram (mg/kg)), these values were attributed <br /> to laboratory contamination. Isolated low concentrations (15 to 94 mg/kg) of oil and grease and total <br /> petroleum hydrocarbons were reported in various soil samples. The location of the soil borings are <br /> presented in Figure 2 and the analytical results are attached in BEM's tables presented in Enclosure A. <br /> In mid September 1996, BEM installed four soil borings using a hollow stem auger drilling rig on-site. <br /> Soil samples were not analyzed from the borings. Ground water grab samples were collected from <br /> within the augers, and not according to standard protocols for ground water sampling, and analyzed for <br /> VOCs, semi-VOCs, TPH, metals, pesticides, and poly chlorinated biphenyl's (PCBs). <br /> Tetrachloroethene was reported in the water samples collected from soil borings B-1 and B-2 at 53.1 <br /> and 17.7 micrograms per liter(pg/L)respectively. Trichloroethylene was reported in the water samples <br /> from borings B-1, B-2, and B-3 at 25.2, 414, and 7.6 gg/L respectively. Neither compound was <br /> reported in the water sample from B-4. BEM's table presenting the complete analytical results from the <br /> four water samples are presented in Enclosure B and the locations of the borings are presented in <br /> Figure 2. <br /> Proposed Scope of Work <br /> Monitoring Wells <br /> At the request of BBA,Delta proposes to install six ground water monitoring wells at the site. Three of <br /> these wells are proposed to be installed along the northern property boundary. The remaining three <br /> wells will be installed at the southern and southeastern perimeter of the property. The location of these <br /> wells are shown on Figure 3. The intent of these wells is to evaluate upgradient ground water quality <br /> prior to the Holz site, and water quality downgradient of Holz. The monitoring wells will be installed <br /> and sampled using the methods described in Enclosure C(Field Methods and Procedures). <br /> During drilling, soil samples will be collected at a minimum of five foot intervals or at changes in <br /> lithology. Each soil sample collected will be screened in the field using a flame ionization detector <br /> (FID) or similar device. Soil samples will be logged by a geologist using visual and manual methods <br /> according to the Unified Soil Classification System. A minimum of four soil samples will be submitted <br /> from each boring to a California-certified laboratory for analysis of total petroleum hydrocarbons <br /> (TPH) as gasoline, TPH as diesel, benzene, toluene, ethyl benzene, and total xylenes (BTEX), volatile <br /> organic compounds (VOCs), and CAM 5 metals. Soil sample selection will be based upon the field <br /> screening results and stratigraphic location. One soil sample collected within a five foot interval from <br />
