project name and location, the date and time, and the samplers <br /> initials. Samples will then be placed in Zip-Lock type plastic bags, <br /> sealed, and placed on ice in a cooler Information noted on the label <br /> will be recorded on a chain-of-custody form. After completion of <br /> drilling, the samples will ether be shipped or delivered to the <br /> laboratory. <br />' Drill cuttings from each boring will be placed in DOT approved 55- <br /> gallon drums. After each drum is filled, it will be sealed, then <br /> labeled. <br /> -Monitofm Wellq <br /> Monitoring wells will be constructed using 2-inch diameter, schedule <br /> 40 PVC flush-thread casing and screen. The well screen will have a <br /> nominal length of 5 feet and will have a slot size of 0.01 inch. The <br /> bottom of the screen will be closed with a schedule 40 PVC flush- <br /> threaded plug. The top of the well will be capped with a lockable <br /> expandable plastic plug and covered with a slip cap. All casing <br /> materials will be cleaned and decontaminated, prior to placement, by <br /> the use of steam. <br /> The annular space between the borehole wall and well screen will be <br /> backfilled with clean Lone Star, or equivalent, 0/30 mesh sand. The <br /> sand will be supplied to the job site in sealed paper sacks. The sand <br /> pack will extend from the bottom of the boring to approximately 2 feet <br /> above the top of the well screen. <br /> Above the sand pack, a nominal 2-foot layer of bentonite pellets will be <br /> placed. The pellets will be supplied to the fob site in sealed plastic <br />' pails <br /> The remainder of the boring will be backfilled with grout The grout <br /> will consist of Type I-II cement, well mixed with bentonite powder <br /> and sufficient water to create a fluid. Depending on the depth of <br /> space to be grouted, the grout may be tremied into place or poured. <br />' The wells will be covered with a utility box set flush with the ground <br /> surface. The box will have a steel cover and will be set in grout to <br /> secure it in place <br />' Both wells will be developed, then sampled The development will <br /> consist of removing a minimum of three well volumes of water <br />' Water levels will be checked before and after development, and the <br /> purged water will be monitored for conductivity, temperature, pH, <br /> and a visual estimate of clarity The purged water will be placed in <br /> DOT-approved 55-gallon drums. After development, the drums will <br /> be sealed and labeled <br /> 2-2 <br />
