SOIL SAMPLING PROCEDURES <br /> Drilling Details <br /> Drilling Method <br /> The boring(s) will be advanced with a hydropunch rig (typically truck mounted). The soil cuttings <br /> brought to the surface will be examined and placed in 5 gallon buckets. Disposal will be based on the <br /> analytical results of the cuttings. The soil samples will be collected into clean disposable tubes, sealed <br /> with Teflon,and capped. However,up to 8 soil samples are anticipated to be retained for analysis. <br /> If groundwater is encountered,a grab water sample will be collected. The water samples will be placed in <br /> laboratory approved containers,placed on ice and transported to the laboratory. <br /> Boring Abandonment <br /> All borings will be sealed and abandoned in accordance with EHD requirements. <br /> Quality Assurance/Quality Control(QA/QC) Procedures <br /> Quality Assurance/Quality Control (QA/QC) procedures will be used to minimize the potential for <br /> contamination of soil samples. The QA/QC procedures may include the use of single-use sampling <br /> equipment, decontamination of drilling and sampling equipment by washing with a solution of potable <br /> water and Liqui-Nox solution or equivalent between borings, changing latex protective gloves after each <br /> sample, and recording sample information on chain-of-custody forms. <br /> Sample Laboratory Tests <br /> Groundwater samples will be transported to a California state certified analytical laboratory where the <br /> following Environmental Protection Agency(EPA)tests will be performed:total petroleum hydrocarbons <br /> as gasoline (TPH-g) by 801513, total petroleum hydrocarbons as diesel (TPH-d), VOCs by 8260, and <br /> metals by EPA 6010/7000(arsenic,barium, cadmium,chromium,lead,mercury, selenium,and silver). <br /> 5. PROPOSED TIME SCHEDULE FOR WORK <br /> Assuming approval of this workplan, we propose to perform the work as soon as scheduling allows. <br /> Standard laboratory turn-around is ten business days. We will forward the results of the work to the <br /> Client within one week of receipt of the laboratory results. <br /> ©ENVIRO ASSESS ENVIRONMENTAL•ENGINEERING•GEOLOGY <br /> PO BOX 1154,BONNERS FERRY,ID 83805 PHONE(877)629-6838 FAX(877)623-5493 <br />
