North Cal Construction proposes to install one (1) groundwater <br />monitoring well to determine ground water hydrocarbon content. <br />Plat 2 shows the proposed boring location. We will: <br />*Drill one boring with a truck mounted 10 inch to a 12 inch <br />diameter hollow -stem auger. <br />*Extend the boring 10 feet into groundwater. <br />*Log the boring. <br />*Convert the boring to monitoring well with a four (4) inch <br />PVC casing which is screened from the bottom of the boring to <br />approximately five (5) feet above the groundwater level (Plate <br />3 shows completion detailed for a typical monitoring well <br />installation). <br />*Develop the wells (minimum of four well volumes of water) and <br />take groundwater samples with stainless steel bailer. <br />*Collect the samples in two (2) liter glass bottles with <br />— teflon lined caps. <br />7 <br />
