Section 3 • <br /> Ah Surveying and Sampling <br /> 3.5.1 QUALITY ASSURANCE/QUALITY CONTROL <br /> All data collection will be in accordance with proper sampling and field measurement procedures <br /> as outlined below. The QA/QC program components for the field include: <br /> • Decontamination of field sampling equipment <br /> • Calibration of all field measuring equipment <br /> • Sample logging and chain of custody procedures <br /> • Sample labeling <br /> • Ensuring that all samples are obtained, maintained, and shipped according to QA/QC <br /> procedures <br /> All equipment used to obtain field measurements (pH meter, specific conductance meter, etc.) <br /> will be calibrated according to manufacturer's directions. Calibration will be performed prior to <br /> the beginning of the sampling event. <br /> 3.5.2 DECONTAMINATION <br /> Non-dedicated sampling equipment will be cleaned by hand and on polyethylene sheeting or in <br /> contained bins. Cleaning will include: <br /> 1. If necessary, removing adhered soil particles by scrubbing with a hand brush in solution <br /> of potable water and a non-phosphate detergent(Alconox). <br /> 2. Rinsing with free-flowing potable, deionized, or distilled water. <br /> 3. Rinsing with chlorine solution prepared with potable, deionized, or distilled water. <br /> Dedicated hand bailers will be rinsed with potable water. If this does not result in an acceptable <br /> cleansing of the bailer (e.g. soil particles adhere to the bailer), decontamination will follow that <br /> of non-dedicated equipment. <br /> 3.5.3 FIELD FORMS/SAMPLE IDENTIFICATION <br /> All field forms for activities conducted during the field program will be maintained. Information <br /> concerning sample collection procedures, sample identification, and any other pertinent <br /> information or observations will be recorded on the field forms. Copies of the field forms will <br /> become part or the project file for further reference. <br /> A sample identification system will be used to identify each sample location and sample type <br /> collected from the facility. This will provide a tracking system to allow for retrieval of <br /> information and to insure that each sample is uniquely numbered and will be provided on both <br /> the sample label and chain of custody. The sample identification will consist of the following <br /> minimum information: <br /> • Site identification; <br /> • Sampler's initials; <br /> • Applicable Preservatives; <br /> • Date and time sampled; and, <br /> April 2007 City of Ripon Wastewater Treatment Facility <br /> 3-4 Groundwater Monitoring Well Installation Workplan <br />
