The Contractor shall inject 55 gallons of sodium hypochlorite and 10 gallons of MP – 2000 (phosphate replacement) followed by a calculated amount of water to displace the chemicals to an appropriate radius in the well. The amount of water to displace chemicals shall be three times the volume of water in the well casing based on static water level, casing diameter, and well depth. The chemicals will then be surged for four hours and pumped off after neutralization. Contractor will then perform a specific capacity test to monitor progress of treatment. The results of the chemical treatments will determine if further treatment is needed. The Department’s deep wells/pumps technician or their representative will advise if additional treatments are needed. The Contractor shall perform a video inspection of the well as specified in this procedure. Submit video log to Engineer on portable electronic media or through file transfer system approved by Engineer.

Contractor will then reinstall the department’s well pump, motor, and pump column after it has been cleaned at the Contractor’s facility.

Conduct a Specific Capacity Test After All Treatments. The specific capacity (discharge rate per foot of drawdown) shall be determined by performing a step test ending at the rated capacity of the bowl in each particular well. The steps shall be 25%, 50%, 75%, and 100% of rated capacity of pump bowl assembly, Each step of the test shall be at least 15 minutes in length and no longer than 30 minutes in length. This test shall be performed with the permanent bowl, pump, and column installed. The results will help show the effectiveness of the treatments. Submit results to Engineer.
