Conduct wire-brushing and bailing of sediment fill from the bottom of the casing. 4. Conduct an interim video survey of the entire well casing. 5. Conduct chemical treatment of the well using Herc Chem Tech LLC (HCT) solutions. Add additional chemical treatment with acid. 6. Perform mechanical redevelopment via simultaneously swabbing and airlifting of the chemical solutions from the well. Fluids generated during this process shall be treated prior to discharge to the local storm drain system. 7. Perform an interim video survey to help ensure the effectiveness of the chemical and mechanical rehabilitation operations. 8. Perform a caliper survey to verify the casing diameters of the well. 9.

Remove the test pump and perform a final video survey to check the casing liner for possible damage from installation and/or removal of temporary test pump, and to determine the amount of sediment fill at the bottom of the casing liner; bail the accumulated sediment. 16. Re-install the new pump components in the well and conduct vibration testing, and trim balance; disinfect the pump components during installation. 17.
