APPENDIX D <br /> WASTE HANDLING AND DECONTAiv1INATION PROCEDURES <br /> Decontamination: Any drilling, sampling or field measurement equipment that comes <br /> into contact with soils or groundwater will be properly decontaminated prior tc its use <br /> at the site and after each incident of contact with the soils or groundwater being <br /> investigated. Proper decontamination is essential to obtain samples that are <br /> representative of environmental conditions and to accurately characterize the extent of <br /> soil and groundwater contamination. Hollow-stem auger flights and the drill bit will be <br /> steam-cleaned between the drilling of each well. <br /> All sample equipment, including the split-tube sampler and brass tubes, will be cleaned <br /> by washing with tri-sodium phosphate detergent, followed by sequential rinsing with tap <br /> water, and deionized water. <br /> Waste Handling: Waste materials generated during site characterization activities will <br /> be handled and stored as hazaroous waste and will be stored on site in appropriately <br /> labeled containers. Waste materials anticipated include drill cuttings, development and <br /> purge water, water g_nerated during aquifer testing, water generated during <br /> decontamination, and used personnel protection equipment stiolt as gloves and Tyvek. <br /> The site owner will be responsible for providing the storage containers and will be <br /> responsible for the disposal of the waste materials. Drill cuttings from individual <br /> borings will be stored separately in drums or coverea by plastic sheeting and the <br /> appropriate disposal procedure will be determined by the site owner or TPE following, <br /> receipt of the soil sample analytical results. Drums or plastic sheeting will be IaFeled <br /> to show material stored, known or suggested contaminant, date stored, expected <br /> removal date, company name, contact, and telephone number. ;+. <br />
