SOP for Surface Water Sampling — Hansen Project 1 <br />1. INTRODUCTION <br />The purpose of this document is to define the standard procedure for collecting surface water samples for water <br />quality analysis. This Standard Operating Procedure (SOP) serves as a supplement to the Quality Assurance <br />Project Plan (QAPP) prepared for the Baseline Hydrologic Monitoring Plan. This procedure gives descriptions <br />of equipment, field procedures, and Quality Assurance /Quality Control (QA/QC) procedures necessary to <br />collect surface water samples. The sample locations and frequency of collection are specified in the Baseline <br />Hydrologic Monitoring Plan. <br />2. EQUIPMENT <br />Certified clean sample bottles will be obtained from the analytical laboratory. Several extra sample bottles will <br />be obtained in case of breakage or other problems. <br />Equipment used during surface water sample collection: <br />• Swing sampler and pole <br />• pH meter (with automatic temperature compensation) <br />• Specific conductance meter <br />• Thermometer (or combined T /pH/SC meter) <br />• Dissolved oxygen (DO) meter <br />• Oxidation reduction potential (ORP) meter <br />• Decontaminated, 1 -liter polyethylene bottle for sample collection and filtering <br />• Sample bottles, labels, and preservatives <br />• Plastic squeeze or spray bottle filled with deionized or distilled water <br />• Cooler with ice <br />• Chain of custody (COC) forms, surface water field sampling data sheets, and custody seals <br />• Pocket calculator <br />• Fieldbook and (optional) field sampling forms <br />• Appropriate health and safety equipment (personal protective equipment) <br />Equipment used during sample filtration: <br />• Disposable 0.45 micron filters (1 per sample) <br />• Tygon (or other flexible, laboratory- grade) tubing (approx. 18 inches per sample) <br />• Electric peristaltic pump or electric drill powered pump <br />Equipment used during decontamination: <br />• Liquinox® or Alconox® soap (or equivalent) <br />• Potable tap water <br />• Deoonized or distilled water <br />• Large sponges <br />• Decontamination buckets /pails <br />• Several "spray" or "squirt" bottles <br />4153A.140129 Whetstone Associates <br />
