Contractor shall submit to the Engineer in the writing the following well <br />development data for each well development. Submittal shall be made within two <br />business days of completing well development. Engineer may request any other <br />data in the field. <br />1. Name of project, site, well identification number, date and time of development <br />and name of person developing the well. <br />2. Method used for development, to include size, type and make of equipment, <br />bailer, and/or pump used during development. <br />3. Depth to bottom of well pre and post development <br />4. Static water level before and after well development <br />5. Time spent developing the well by each method, to include typical pumping rate, <br />if pump is used in development. <br />6. Minimum purge volume <br />7. Amount of water purged. Provide physical character of water removed, to <br />include changes during development in clarity, color, particulates, and odor. <br />8. Volume and source of water added to the well, if any. <br />9. Volume and physical character of sediment removed, to include changes during <br />development in color orodor. <br />10. Readings of pH, specific conductance, turbidity, DO, oxidation / reduction <br />potential (ORP), and temperature taken before, during, and after development. <br />11.
