' MW-1 through MW-5 were completed as ground water monitoring wells with slotted screen <br /> iinstalled from approximately 15 to 35 feet bsg in bonngs MW-1 through MW-4 and from <br /> approximately 69 to 74 feet bsg in boring MW-5 Locations of the monitoring wells are illustrated <br /> ' on Figure 2 <br /> Results of the well installation and subsequent sampling delineated the dissolved hydrocarbons and <br /> ' indicated direction of ground water flow generally towards the northeast Ground water monitoring <br /> enabled delineation of the dissolved hydrocarbon plume The vertical assessment of the dissolved <br /> ' hydrocarbon plume Analytical data is presented on the attached tables <br /> ' STRATIGRAPHY AND DEPTH TO GROUND WATER <br /> Silt, with a tan, brown or gray color, apparently depending on hydrocarbon impact, was generally <br /> t encountered from a depth of approximately 5 feet to 35 feet bsg in the shallow well bonngs, the <br /> coarsest maternal was silty sand,collected at a depth of 25 feet bsg in boring MW-2 Silty sand was <br /> generally encountered to a depth approximately of 40 feet to 45 feet bsg Generally poorly graded <br /> 1 sand and silty sand was encountered between 60 and 75 feet bsg 1n boring MW-5 Ground water was <br /> encountered at a depth of 30 feet bsg during drilling <br /> 1 <br /> 1 <br /> t <br /> � 1 <br />
