20 August 2002 <br /> AGE-NC Project No 01-0827 <br /> Page 2 of 5 <br /> • TPH-d and/or TPH-mo were detected in remaining soil samples at low concentrations <br /> On 08 and 15 July 2002, a total of five soil borings were advanced at the site Based on the soil and <br /> ground water data collected, AGE concluded <br /> • Silt and clay with a tan or gray color, apparently depending on hydrocarbon impact, was <br /> encountered from a depth of approximately 5 feet to 28 feet bsg Gray to tan sand with gravel <br /> was present at depths of 28 feet to 30 feet bsg Silt and clay was encountered again at depths <br /> of 30 feet to 50 feet bsg A stratigraphic cross section is depicted in Figure 3 <br /> • The maximum hydrocarbon concentrations in soil were detectedin.the area of the former burn <br /> pit area,sample##2 south The maximum concentrations of TPH and BTEX compounds were <br /> detected in samples collected above 20 feet bsg <br /> • Approximately 311 kg of diesel and 509 kg of fuel oil remain in the soil at the site, to an <br /> approximate depth of 20 feet bsg <br /> • The vertical and lateral extent of the impacted soil were delineated by the soil samples <br /> . analyzed <br /> • Ground watei was encountered at a depth of 30 feet bsg during drilling Ground water <br /> samples were not impacted by hydrocarbons <br /> 3.0. SCOPE OF WORK <br /> The proposed scope of work will include the following tasks <br /> • Planning and pre-field work activities <br /> • Soil excavation and sample collection/analysis <br /> • Excavation backfilling <br /> • Soil disposal <br /> • Report preparation <br /> 3 1 PRE-FIELD WORK ACTIVITIES <br /> A health and safety plan will be prepared in accoi dance with Occupational Safety and Health <br /> .
