• The annulus above the bentonite will be grouted with a cement slurry placed by tremmie if significant water is present in the boring. The cement grout should extend to a depth of approximately 1 foot below the ground surface. • A traffic -rated housing will be placed above the well casing and set in concrete. The well housing should be set approximately one -inch above the ground surface. The well number will be recorded on the well monument. A locking device will be installed to minimize the likelihood of unauthorized access to the well. • The grout will be allowed to cure for approximately 48 to 72 hours prior to monitoring well development. • A well reference measuring point will be placed on the north side of the monitoring well casing. The location and elevation of the top of casing at the reference point of the newly installed well and existing well will be surveyed relative to mean sea level by a licensed surveyor to second order accuracy. • The water level and depth to the bottom of the well will be measured to the nearest 0.01 -foot using an electronic water level indicator. The presence of free -phase petroleum product will be assessed. Well Development Procedures • Well development will be conducted by initially surging the well with a surge block, followed by removal of water with a pump and/or bailer. Surging will be conducted over 5 -foot intervals of the screened well casing, beginning at the bottom of the well. Surging should be conducted at least twice over the entire length of the well screen. Well development activities will be recorded on well development forms. • A minimum of five well casing volumes of water will be removed from the well during development. The temperature, conductivity, and pH of the groundwater removed during development of the well will be monitored. Development should continue until the measured groundwater parameters have stabilized and the turbidity of the water removed has decreased to a degree as judged acceptable. • Water removed from the well will be contained in a portable polyethylene tank. The tank will be transported and stored at the IT office pending laboratory analysis and disposal of the groundwater. • Groundwater Sampling Procedures • Field activities and equipment utilization will be recorded on field report forms.
