Ryegrass Limited Purpose Landfill and Balefill Closed Landfill <br />Groundwater and Leachate Sampling and Analysis Plan <br />Kittitas County Solid Waste <br />2.5.1.1 Fief Sampling Data Sheet <br />A field sampling data sheet (example in Appendix C will be filled out for each sample point This sheet <br />contains information regarding Site and well conditions, sampling and purging procedures, and field <br />measurements. At a minimum, the following information must be documented: <br />1. Purging Information, including date, time, well number, casing volume, elapsed time, <br />discharge color (if different than for sampling), water level before and after purging. Note if <br />the well was dry, purged dry, or was otherwise impossible to sample. <br />2. Purging and Sampling Equipment, including pump type and tubing material. <br />3. Field Measurements, including fluid surface elevation (depth to groundwater or to leachate), <br />temperature, pH, dissolved oxygen, and specific conductance. <br />4. Additional Field Measurements, as necessary. <br />1. Note: Samples collected from springs do not have purging equipment. Field measurements are <br />taken by filling the instrument calibration cup and reading the measurements after the readings <br />have stabilized. <br />2. A .2 Fief Observations <br />The comments section on the field sampling data sheet will include such field observations as the following: <br />■ Weather condition: wind direction, speed, upwind activities (ensure that vehicles or gasoline - <br />engine generators or compressors are not upwind of sampling activities), temperature, and <br />barometric pressure (if required). <br />■ Sample appearance, including odor, color, and turbidity: <br />—• 9LLQC: (e.g., rotten eggs, earthy, strong, moderate, slight, metallic, landfill gas - do not <br />sniff sample). <br />—• Color: True "color" is the color after turbidity has been removed, if samples are filtered. <br />True color may be caused by metallic ions, humus, peat, or industrial chemicals. Hold the <br />sample up to the light and describe the true color in as much detail as possible (color <br />charts are acceptable descriptive methods). If samples are not filtered, then color may be <br />a function of turbidity. <br />—• Turbidity: <br />► None: sample is clear. <br />► Trace: sediment slightly clouds or colors sample; does not accumulate in bottle. <br />► Moderate: definite cloudiness, sediment accumulates at bottom of bottle. <br />► High: muddy or dark brown appearance. <br />When a turbidity -measuring device is used, measurements must be provided in <br />nephelometric units. <br />■ Reference point for well measurements (i.e., is it clearly marked on top of casing?). <br />■ Well/Location ID where the duplicate sample is collected. <br />■ Calculations for purge volumes and temperature conversions. Note when wells are purged <br />dry. <br />■ Duplicate field measurement results. <br />■ Other conditions, such as sample splits with regulatory agencies, potential safety or health <br />hazards (e.g., landfill gas in well). <br />April 2024 1553-1763-010 2-5 <br />Revised May 2024 <br />
