Well Development and Sampling <br /> After the wells were completeld, development was done <br /> with a teflon bailer. The bailer acts as a surge block to <br /> clear the slotted screen of silts that may have clogged the <br /> openings during completion. The bailer is used to remove <br /> most of the silt from the bottom of the casing and develop <br /> the water flow through the annular sand pack and machine <br /> slotted screen. <br /> Subsequent to development, water samples were collected <br /> from the monitoring wells using the teflon bailer. Collected <br /> samples were transported to California Water Labs of Modesto <br /> in an iced cooler under chain-of-custody control . <br /> VI. LABORATORY ANALYSIS <br /> A. Soil Analysis <br /> Equal amounts by weight of soil samples from each boring <br /> from three feet below ground surface were rapidly mixed and <br /> resealed in our laboratory. Samples were transported to <br /> California Water Labs - in an iced cooler under chain-of- <br /> custody. The composited sample was analyzed for EPA 608, EPA <br /> 624 and EPA 625 organics, 2,4-D, 2,4, 5-TP, and metals. <br /> Analytical results of soil testing were either non-detected <br /> within the limits of the test method or consistent with <br /> naturally occurring levels. <br />
