Table 1 <br /> Scope of Work - Phase II Site Assessment <br /> (continued) <br /> Task Description <br /> Task 6 Field Screening Program <br /> A-zone Groundwater sample Collect one A-zone groundwater sample upgradient of <br /> facilities using HydroPunch <br /> B-zone Groundwater samples Collect 13 B-zone groundwater samples using <br /> HydroPunch to assess lateral extent of B-zone impacts <br /> C-zone Groundwater samples Collect 16 C-zone groundwater samples using <br /> HydroPunch to assess vertical and lateral extent of <br /> C-zone impacts <br /> Task 7 Exploratory Boring and Well <br /> Installation Program <br /> Well Installation Install B-zone and C-zone monitoring wells at <br /> locations determined following review of CPT and <br /> field screening data for confirmation and monitoring of <br /> B-zone and C-zone impacts. Monitoring wells to be <br /> installed using air-rotary with casing driver equipment <br /> and will be 2-inch-diameter PVC <br /> Well Development Develop and sample B- and C-zone monitoring wells <br /> installed under Subtask 7.1 <br /> Task S Laboratory Analysis <br /> Review Analytical Data Review Results of June 1993 quarterly monitoring <br /> event to determine extent of B-zone impacts <br /> Hydropunch Sample Analysis Analyze 30 HydroPunch samples collected under <br /> Task 5 for TPHG. BTEX, and TPHD on 24-hour <br /> turnaround; dissolved lead on normal turnaround <br /> Analysis of B-zone and C-zone Analyze groundwater samples from B-zone and <br /> monitoring well samples C-zone monitoring wells for TPHG, BTEX, and <br /> TPHD; dissolved lead on normal turnaround <br /> Task 9 Biodegradation Assessment Evaluate current environmental conditions and <br /> Potential enhancement techniques <br /> Sampling and Analysis Sample six A-zone and two B-zone wells for biologic <br /> parameters <br /> Evaluation of Biodegradation Evaluate analytical data to determine biologic <br /> data conditions, potential biodegradation activity, and <br /> techniques which may enhance the natural <br /> biodegradation rates <br /> SAC/PR9,P93W9304031.be-93 Ima5 <br />
