APPENDIX D <br />' WASTE HANDLING AND DECONTAMINATION PROCEDURES <br /> Decontamination: Any drilling, sampling or field measurement <br />' equipment that comes into contact with soils or groundwater will <br /> be properly decontaminated prior to its use at the site and after <br /> each incident of contact with the soils or groundwater being <br />' investigated. Proper decontamination is essential to obtain <br /> samples that are representative of environmental conditions and <br /> to accurately characterize the extent of soil and groundwater <br /> contamination. Hollow-stem auger flights and the drill bit will <br />' be steam-cleaned between the drilling of each well . <br /> All sample equipment, including the split-tube sampler and brass <br />' tubes, will be cleaned by washing with tri-sodium phosphate <br /> detergent, followed by sequential rinsing with tap water, and <br /> deionized water. <br />' Waste Handl_ina: Waste materials generated during site <br /> characterl7ation activities will be handled and stored as <br /> hazardous waste and will be stored on site in appropriately <br />' labeled containers. Waste materials anticipated include drill <br /> cuttings, development and purge water, water generated during <br /> aquifer testing, water generated during decontamination, and used <br /> personnel protection equipment such as gloves and Tyvek. The <br /> site owner will be responsible for providing the storage <br /> containers and will be responsible for the disposal of the waste <br /> t materials. Drill cuttings from individual borings will be stored <br /> separately in drums or covered by plastic sheeting and the <br /> appropriate disposal procedure will be determined by the site <br /> owner or TPE following receipt of the soil sample analytical. <br />' results . Drums or plastic sheeting will be labeled to show <br /> material stored, known or suggested contaminant, date stored, <br /> expected removal date, company name, contact and telephone <br />' number. <br /> 1 <br />
