LJ <br />L <br />• <br />crushing and screening levels. <br />o Three at the contact of the fan level fill with <br />the natural ground surface. <br />The locations of all borings and test pits are indicated <br />on Plate 2, P].ot Plan. <br />The borings were advanced using four-inch diameter <br />continuous-flight augers. "Undisturbed" samples and Standard <br />Penetration Test ("split spoon") samples were taken at se- <br />lected intervals throughout the borings. <br />Monitoring wells were constructed by installing slotted <br />1", 2" or 2z" PVC casing in borings B-3, B-4, B-5, B-6 and <br />B-7, as indicated on the logs of these borings. Details of <br />the construction of the monitoring wells are shown on Plates <br />A-19a through A-19d. <br />The drilling program was supervised by experienced GEO- <br />HYDRO engineer/hydrologists, who classified the soils en- <br />countered by visual and textural examination in the field and <br />maintained a complete log of each boring. These field class- <br />ifications were supplemented by subsequent office inspection <br />and laboratory classification. <br />The nomenclature used to describe the various soil <br />types is described on Plate A-1, Unified Soil Classification. <br />The key to the logs of borings is shown on Plate A-2, and <br />the logs of borings and test pits are presented as Plates <br />A-3a through A-18. <br />Field permeability (falling head) tests were performed <br />in borings B-3A (a shallow boring approximately 20 feet deep <br />offset some 15 Eeet east of boring B-3), B-5, B-6, and B-7. <br />These tests give a measure of the permeability of the <br />soil and fill materials in their natural conditions.
