fir+ <br /> CAM BRIA <br /> conditions at the time of drilling. Please note that the well designations (names) may be <br /> modified depending on the final screen intervals in the completed wells. <br /> Soil and groundwater sampling intervals for the CPT boring will be determined in the field based <br /> on the soil types identified by the electronic logs. Moderate to high permeability soils identified <br /> in the borings will be targeted.for soil and groundwater sample collection. At a minimum, we <br /> will attempt to collect soil and groundwater samples at five different intervals <br /> (e.g., 30,45� 65, 85, and 100 fbg). Groundwater samples from the CPT borings will be collected <br /> using Hydropunch sampling equipment. —` <br /> Soil samples designated for chemical analysis will be retained in stainless steel or brass sample <br /> tubes. The tubes will be covered on both ends with Teflon— sheets and plastic end caps. <br /> Groundwater samples will be contained in appropriate sample containers. Groundwater and soil <br /> samples will be labeled, entered onto a chain-of-custody record, and placed into a cooler with ice <br /> for transport to a State of California certified laboratory for analysis. <br /> The wells will be secured with a locking cap under a traffic-rated well box. A licensed surveyor <br /> will survey the wellhead relative to mean sea level. The surveyor will also survey the well <br /> longitude and latitude per State of California guidelines. <br /> Well Development and Sampling: The newly installed wells will be developed prior to <br /> sampling. After well development,Blaine Tech Services, Inc. (Blaine)will sample the wells and <br /> submit the samples to a state-certified laboratory for chemical analyses. <br /> Chemical Analyses: Groundwater and soil samples will be analyzed for total petroleum <br /> hydrocarbons as gasoline, benzene, toluene, ethylbenzene, xylenes,, methyl tertiary butyl ether, <br /> tertiary butyl alcohol,and 1,2-dicholorethane by EPA Method 8260. <br /> Report Preparation: Within 60 days of the receipt of the groundwater monitoring report from <br /> Blaine, Cambria will prepare a written report which will include field procedures, laboratory <br /> results,boring logs, conclusions, and recommendations. <br /> 0778 4 <br />
