1 <br /> I <br /> ground level , it is felt that further excavation of the site of <br /> ' the LIST is not a vx ab 1 e option at this time. The water quality <br /> is already highly degraded by salts and other substances, and <br /> breaching the water table by removing additional spoil may <br /> exacerbate the situation. It as believed that hand-angered <br /> ' borings offer the best and most cost--effective method of <br /> determining the extend of the contamination. <br /> ' 1. Using a 4" hand auger, auger to a depth of approximately 10 <br /> feet, or into the capillary fringe or transition zone. Sail <br /> samples are to be collected from the teeth of the auger at b' & <br /> 10' , or total augered depth; the bottom soil sample to be taken <br /> ' from the transition zone of possible. Auger hole are to be <br /> located approximately as shown on Plate VII . <br /> ' 2. The soil samples will be collected by the geologist in <br /> properly prepared brass tubes supplied by FGL Environmental , <br /> sealed , labeled and placed on ice pending transfer to the lab for <br /> ' analysis. The auger will be thoroughly cleaned between each run <br /> by rinsing with TSP and then clean water. Samples will be <br /> transported to the lab under proper chain of custody, and <br /> analyzed for BTEX, TPH-S, and soluble lead. <br /> 3. Every effort will be made to avoid penetrating the water <br /> table. <br /> 4. All auger holes will be filled with grout immediately <br /> following final sampling. Removed spoils will be placed in <br /> properly labeled and sealed drums , and stored on site pending <br /> final completion of the project. <br /> A Health and safety plan is attached as Exhibit 0. <br /> Further investigative or remedial work will be proposed after <br /> reviewing the results of the laboratory analyses of the soil <br /> ' samples. <br /> Your prompt review and response to this workplan will be greatly <br /> appreciated; our client is currently marketing the property for <br /> sale, and wishes to have this matter resolved as quickly as <br /> possible. <br /> Yours tr ly, <br /> tiViLLM!
