QUALITY ASSURANCE / QUALITY CONTROL <br /> PROTOCOLS <br /> The following licensed professional people will be involved in <br /> this project. <br /> Geologist: John Cussen Registered Geologist #6506 <br /> Environmental Assessor: John Cussen , REA 1979 <br /> Drillers: Will be Frontier Drilling , C-57 License C57-673504. <br /> Laboratory: Will be Sherwood Labs , Hilmar, CA . <br /> Protocols <br /> Drilling Monitoring Wells: <br /> All downhole equipment will be decontaminated using steam, to clean off all soil prior to use. <br /> Wells will be drilled with a continuous flight hollow stem auger. All wells will have a diameter at <br /> least 4 inches greater than the casing diameter (OD) . <br /> Core samples will be taken every 5 feet. A core of the capillary fringe will be obtained . The well <br /> will be logged geologically and the blow counts will be recorded . Also the odor of each sample will <br /> be noted and the presence of any free hydrocarbon product. <br /> Prior to removing any equipment from the hole the TD will be measured . Once the casing is <br /> placed in the hole an accurate measurement of the total amount of casing must be made. The <br /> difference between the two figures will be explained by the well logger. <br /> All drill cuttings will be placed in drums, sealed and the drilling intervals for the cuttings in each <br /> drum will be marked on the drum . The drums will remain stored at the site until the contamination <br /> can be assessed through the laboratory sampling . <br /> Completion : <br /> Slotted casing (0. 02 inch slots) will be capped with a bottom plug . The slots will extend 5 feet <br /> above the estimated water table indicated during drilling . Clean # 3 sand will be placed opposite <br /> the slotted casing and 1 foot above the last slot. At this time the well will be surged for 5 minutes <br /> to attempt to eliminate any voids in the sand pack. At the end of the surging the top of the sand <br /> will be measured and additional sand will be added if necessary. Directly above the sand a 3 foot <br /> plug of hydrated bentonite chips will be placed. Above the plug a seal of cement grout will be <br /> placed to the surface. The top of the casing will be capped and a traffic box will be cemented in <br /> place around and above the top of the casing . <br /> The cement or bentonite grout will be placed in the annulus by the use of a trime pipe if the total <br /> annulus seal distance is over 30 feet.
