Levine•Fricke•Recon <br /> ENGINEERS,HVDROGEOLOGISTS S APPLIED SCIENTISTS <br /> The groundwater monitoring wells will be used to measure the depth to groundwater and to collect <br /> groundwater samples for subsequent laboratory analysis. One groundwater monitoring well will be <br /> installed adjacent to the pilot borings at a depth that will be determined based on an evaluation of <br /> pilot boring data (Figure 1). A second groundwater monitoring well will also be located in this <br /> parking lot at a location to be determined based on the results of the CPT/PIPP and pilot boring <br /> investigations. We will provide you with a proposed location and schedule for this second <br /> groundwater monitoring well before it is installed. <br /> The tops of the groundwater monitoring wells will be located below the existing parking lot <br /> surface. Traffic-rated well boxes, approximately 14 inches in diameter, will be installed to protect <br /> the new wells. The well boxes will be installed flush with the existing parking lot surface. Locks <br /> will be installed on the wells to prevent unauthorized access. <br /> Before field activities are conducted on the Subject Property, any buried utilities that are present in <br /> the parking lot in the vicinity of the proposed CPT/PIPP borings, soil-vapor borings, pilot borings, <br /> and monitoring wells will be located and marked on the asphalt to prevent any contact with utilities <br /> during drilling. At the end of each work shift, any waste materials generated during the field <br /> activities will be removed and the work area will be cleaned. The CPT/PIPP borings, soil-vapor <br /> borings, and pilot borings will be backfilled with a cement-grout mixture when drilling is <br /> completed. Upon completion of this field work, the asphalt surface surrounding these borings will <br /> be restored to its original condition. <br /> Field Equipment <br /> 1. CPT/PIPP Investigation <br /> Field equipment for the CPT/PIPP investigation will consist of a drilling rig and support vehicles. <br /> Two photographs of CPT/PIPP equipment used at a nearby location are presented in Figure 2. The <br /> work space at each location will be approximately 50 feet by 50 feet, covering an area of <br /> approximately 2,500 square feet. The work space will be cordoned off during the drilling period to <br /> prohibit access by unauthorized personnel. Vehicles will be moved off the Subject Property at the <br /> end of each work shift. <br /> 2. Soil-Vapor Investigation <br /> Field equipment for the soil-vapor investigation will consist of a pickup truck mounted with a <br /> hydraulic-push rig to collect soil-vapor samples and a mobile laboratory, towed by a pickup truck, <br /> to analyze the samples. Photographs of the soil-vapor truck and mobile laboratory are presented in <br /> Figure 3. The work space at each location will be approximately 20 feet by 20 feet, covering an <br /> area of approximately 400 square feet at each location. The hydraulic-push rig will be moved off <br /> the Subject Property at the end of each work shift. The mobile laboratory will be parked on the <br /> adjacent Lincoln Properties, Ltd. property, behind Trader Joe's, between work shifts. <br /> LC-ACCITLTR:IBA 3 <br />
