rtl <br /> • 3 ) Drill two (2) soil borings at the site to approximately 100-feet b g s <br /> using a cone penetrometer testing (CPT) drill rig (Figure 3) Collect <br /> a capillary zone soil sample and discrete depth groundwater samples <br /> from each soil boring <br /> 4 ) Analyze one (1) soil sample from each boring and up to three <br /> discrete depth groundwater samples from each boring at a CALrEPA <br /> certified analytical laboratory for TPH-G, benzene, toluene, ethyl <br /> benzene and total xylenes (collectively known as BTEX), the fuel <br /> oxygenates MTBE, TBA, TAME, DIPE and ETBE, the lead scavengers <br /> 1,2-di chloro ethane (1,2-DCA) and 1 ,2-dibromoethane (1,2-EDB), <br /> and the alcohols ethanol and methanol by EPA Method 8260 <br /> 5 ) Drill five soil borings to a depth of no greater than 20-feet bgs a n d <br /> install a groundwater monitoring well in each boring <br /> 6 ) Analyze two soil samples collected from each boring described i n <br /> task 5 for TPH-G, BTEX, the fuel oxygenates MTBE, TBA, TAME, DIPE <br /> and ETBE, the lead scavengers 1,2-DCA and 1,2-EDB, and the alcohols <br /> ethanol and methanol by EPA Method 8260 <br /> 7 ) Develop each monitoring well <br /> 8 ) Collect groundwater samples from each monitoring well f or <br /> analyses <br /> 9 ) Analyze the groundwater samples at a CAL-EPA certified <br /> environmental laboratory for TPH-G, BTEX, the fuel oxygenates <br /> MTBE, TBA, TAME, DIPE and ETBE, the lead scavengers 1,2-DCA a n d <br /> 1,2-EDB, and the alcohols ethanol and methanol by EPA Method <br /> 8260 <br /> 10) Survey the top of casing elevation of each well, and determine t h e <br /> groundwater flow direction and gradient beneath the site <br /> 11 Prepare a report detailing the methods and findings of the soil a n d <br /> groundwater assessment <br /> Details of the assessment are presented below <br /> 574 West Grant Line Road Report — October 2000 <br /> -3- <br />
