Danny Kipp, Bob Moline and <br />Mark Quincy all of Coors Energy were present during the inspection, as was Eric Jacobs of the Colorado <br />Department of Health and Environment (CDPHE). Skies had high clouds, and temperatures reached the low 70 <br />degrees F. This inspection focused on groundwater sampling. <br />HYDROLOGIC BALANCE- Rule 4.05 <br />General Requirements 4.05.1; Ground Water Monitoring 4.05.13; <br /> <br />Groundwater monitoring is typically carried out in April and September. The September 2016 sampling of the 6 <br />ground water monitoring wells was observed. Two samples are collected from each well. A Hanna multi meter <br />was utilized for sampling the following field parameters: <br />1. Temperature in degrees Celsius (C). <br />2. Electrical Conductivity <br />3. pH <br />4. Static water level <br /> <br />The monitoring procedure followed is outlined below: <br /> <br />1. Measure static water elevation in well. <br />2. Bail the well five times using a one liter bailer and rinse sampling equipment (funnel and field sample <br />bottle) with the fifth bailer volume. <br />3. Clean probe for field sample parameters with distilled water. <br />4. Sample for field parameters, and fill lab sample bottles on sixth bail. <br />5. Evacuate the well with the submersible pump. <br />6. Measure static water elevation. <br />7. Bail the well five times, rinse apparatus and sample for field parameters on sixth bail. <br />8. Fill out chain of custody and transport sample to office refrigerator for storage until taken to lab. <br />No washing of the pump, pump hose and bailer took place between sampling. <br />The monitoring protocol is described in Section 2.04.03 of the permit document.
