I <br /> - A traffic-rated housing was placed above the well casing and set in concrete The <br /> well housing was set approximately one-inch above the ground surface <br /> (the housing for MW-3R was flush mounted) A locking device was installed to <br /> minimize the likelihood of unauthorized access to the well <br /> t - The grout was allowed to cure for approximately 48 to 72 hours prior to monitoring <br /> well development <br /> - A well reference measuring point was placed on the north side of the monitoring <br /> well casing The location and elevation of the top of casing at the reference point <br /> of the newly installed well and existing well were surveyed relative to mean sea <br /> level by a licensed surveyor to second order accuracy <br /> The water level and depth to the bottom of the well were measured to the nearest <br /> 0 01-foot using an electronic water level indicator The presence of free-phase <br /> petroleum product was assessed <br /> Well Development Procedures <br /> A minimum of five well casing volumes of water was removed from the well <br /> during development The temperature, conductivity, and pH of the groundwater <br /> removed during development of the well were monitored Development continued <br /> until the measured groundwater parameters had stabilized and the turbidity of the <br /> water removed has decreased to a degree as fudged acceptable Well development <br /> activities were recorded on well development forms <br /> o Water removed from the well was contained in a portable Baker Tank The tank <br /> was stored at the site pending laboratory analysis of the groundwater <br /> Groundwater Sampling Procedures <br /> Field activities and equipment utilization were recorded on field report forms <br /> - A disposable polyethylene bailer was used for collection of each groundwater <br /> sample Polyethylene bailers were discarded after each sample is collected <br /> - New nylon rope was used to lower the bailers into the wells The nylon rope was <br /> discarded after each well <br /> - Groundwater samples were placed into laboratory-supplied containers containing <br /> preservatives, when appropriate <br /> - Groundwater was discharged from the bailer via a bottom-emptying device <br /> Discharge to the containers was conducted in a manner to minimize bubbling and <br /> agitation of the liquid The containers were filled to the top forming a meniscus to <br /> minimize the headspace <br /> SHAW ENVIRONMENTAL,INC <br /> 11SAr-RFP 11COMMONISACDPV0031PRJ188018800391 A 3AE DOC <br /> B-3 <br />
