• i <br /> • QUALITY ASSURANCE/QUALITY CONTROL <br /> PROTOCOLS <br /> The following licensed professional people will be involved in <br /> this project. <br /> Geologist: Richard Merriam, Certified Engineering Geologist <br /> California Registration # 850 . <br /> Environmental Assessor: John Cussen, REA # 1979 <br /> Project Manager: Mr. John Cussen <br /> Drillers: Will have a current C--57 Drilling license. <br /> Laboratory: Will be a California State Certified Laboratory. <br /> Protocols <br /> Drilling Monitoring Wells : <br /> All downhole equipment will be decontaminated using steam, to <br /> clean off all soil prior to use. Wells will be drilled with a <br /> continuous flight hollow stem auger. All wells will have a <br /> . diameter at least 4 inches greater than the casing diameter (OD) . <br /> Core samples will be taken every 5 feet. A core of the capillary <br /> fringe will be obtained. The well will be logged geologically <br /> and the blow counts will be recorded. Also the odor of each <br /> sample will be noted and the presence of any free hydrocarbon <br /> product. <br /> Prior to removing any equipment from the hole the TD will be <br /> measured. Once the casing is placed in the hole an accurate <br /> measurement of the total amount of casing must be made. The <br /> difference between the two figures will be explained by the well <br /> logger. <br /> All drill cuttings will be placed in drums, sealed and the <br /> drilling intervals for the cuttings in each drum will be marked <br /> on the drum. The drums will remain stored at the site until the <br /> contamination can be assessed through the laboratory sampling. <br /> Completion: <br /> Slotted casing (0. 02 inch slots) will be capped with a bottom <br /> plug. The slots will extend 5 feet above the estimated water <br /> table indicated during drilling. Clean # 3 sand will be placed <br /> opposite the slotted casing and 1 feet above the last slot. At <br /> this time the well will be surged for 5 minutes to attempt to <br /> • eliminate any voids in the sand pack. At the end of the surging <br /> the top of the sand will be measured and additional sand will be <br /> Page 4 <br />
