GEOSYNTEC CONSULTANTS <br /> Mr. Michael L. Frey <br /> 9 April 2003 <br /> Page 5 <br /> for 10 hour days . The labor included in the budget estimate assumes that the groundwater <br /> sampling fieldwork will require approximately four days (40 hrs) for monitoring well <br /> sampling (four wells per day) . Also included under this task is two days ( 16 hrs) for <br /> database management and data evaluation. <br /> Waste characterization will also be necessary under this task; however, the budget <br /> estimate for this task does not include the cost for waste characterization analyses . <br /> GeoSyntec assumes that Indian River County will contract directly with Test America for <br /> this laboratory analysis . Disposal will be handled by Indian River County as discussed <br /> below. With respect to IDW generated during GeoSyntec ' s groundwater sampling <br /> fieldwork at the site, GeoSyntec will drum the purge water, stage the drums on-site, and <br /> mark each drum to indicate the source of the waste (e . g. , monitoring well numbers , etc . ) <br /> contained within each drum, the generation date, and contact information . These drums <br /> will be sampled with the drums generated during the second semi-annual plume <br /> monitoring sampling event for the plume monitoring network at the site . The results of the <br /> analyses will be used to assess whether or not the IDW is characteristically hazardous and <br /> to evaluate the feasibility of discharging the purge water to the on-site treatment system. <br /> These drums will be marked as indicated earlier, placed on wood pallets, and stored at <br /> an on-site location designated by the SWDD . If the IDW characterization supports <br /> disposal of the liquid IDW through the on-site treatment system, it may be possible to <br /> discontinue characterization sampling after one to two sampling events . Any required <br /> transport and disposal of wastes from the site would be arranged by the SWDD . <br /> Task 1. 4. Soil Sampling <br /> Under Task 1 .4, GeoSyntec proposes to conduct one day of soil sampling to evaluate <br /> if source material is bound in the organic-rich, silty layer that has been identified in many <br /> borings at the site between 5 ft to 20 ft BLS (thickness of this layer is generally 2 ft to 6 ft) . <br /> The budget estimate includes laboratory analysis of up to ten soil samples for EPA Method <br /> 8021 and analysis of up to six soil samples for fraction organic carbon (foc) by the <br /> Walkley Black method . This information will be critical in evaluating the appropriateness <br /> of source removal activities for the Remedial Action Plan (RAP) to be submitted to FDEP <br /> during summer 2003 . <br /> XR03035/R030082 .DOC <br /> r, RECYCLED AND RECYCLABLE � r <br />
