' Nat, Well Installation - After completion of the soil boring, a monitor well will be constructed in the boring. Fifteen feet of 2-inch OD, schedule 40 PVC, 0.002-inch slot screen will be used with approximately 60 feet of 2-inch OD schedule 40 PVC blank casing. The PVC screen and blank casing will be threaded together and inserted down the interior of the hollow stem auger. A clean #3 Monterey sand will be used to pack the screen interval. As the sand is packed around the screen the augers are removed from the boring. Sand packing will continue to approximately 2 feet above the top of the screen. A surge block will be used to ensure the quality of the sand pack and additional sand will be added if needed. Approximately 2 feet of bentonite pellets will be placed above the sand pack and hydrated with clean de-ionized water. A neet cement slurry with approximate three to five percent bentonite gel additive will be mixed and used to grout the remainder of the boring. The well will be finished with a lockable cap and a water-tight flush-mount fl- inch well cover. A quick setting concrete mixture will be used to set the well cover. i Well Development - Development of the newly constructed well will begin approximately 18-hours after its installation. Development will consist of surging combined with removal of water from the well. Groundwater will be removed from the well until suspended sediment concentrations are adequately reduced, or until a maximum of 25 well volumes (approximately 50 gallons) have been extracted. Waste Containment - Waste soils and water produced by the drilling and well development activities will be placed in 55-gallon drums supplied by ICF Kaiser. The drums will be labeled and placed at appropriate locations on the subject property as to not interfere with vehicular traffic flows. It is understood that Union Ice Company will be considered the generator of these wastes. ICF Kaiser will assist Union Ice Company in evaluating disposal options after receiving analytical results. It is anticipated that the waste soils and water generated will be non-hazardous; it may be possible to dispose of the purge water to the storm drain, and the soils might be of suitable quality to use as fill , at the 1320 West Weber facility. Groundwater Sampling - One to two weeks following well development and purging, water samples will be collected using disposable bailers and transferred to appropriate containers. The samples for BTEX analysis will be collected first, and care will be taken to minimize aeration. Sample containers will be laboratory cleaned and prepared with appropriate preservatives. Appropriate chain-of-custody procedures will accompany all samples. The water samples from the wells will be analyzed for the possible presence of TPH extractables (diesel, oil, kerosene) and benzene, toluene, ethylbenzene, and xylenes (BTEX) by American Environmental Network, a California certified laboratory located in Pleasanton, California. jmflunioniceladdend.wpl ICF KAISER 2
