APPENDIX B<br />

Chemical application<br />

The solution will be applied in accordance with the following guidelines:<br />

Agitation<br />

If the dispersant is to be used for development of a shallow well, the Aqua-Clear PFD/water<br />

solution may be poured directly into the well.<br />

For deeper wells the Aqua-Clear PFD/water solution must be injected down the well using<br />

a tremie line with an isolating injection tool set at the depth of the desired screen interval to<br />

be treated. The injection tool will be flanged on both ends of the desired screened interval<br />

treatment length to isolate the area for treatment. This will ensure the solution is evenly<br />

distributed throughout the screen and that the desired concentration of the Aqua-Clear<br />

PFD/water solution is achieved.<br />

Set the injection tool at the desired treatment depth.<br />

Inject the solution into the tremie line under enough pressure to ensure the solution is<br />

dispersed into the filter pack. This can be accomplished using a transfer pump configuration.<br />

Repeat the treatment until the entire occluded screen interval has been treated.<br />

At a minimum, the PFD solution should remain in the well for 24 hours. During this time the following<br />

agitation activities should be implemented:<br />

Pumping<br />

After injection of the Aqua-Clear PFD/water solution is complete, immediately start<br />

agitation of the solution in the well. Agitation ensures the solution is thoroughly blended and<br />

dispersed into the filter pack and formation interface.<br />

Agitation activities using a surge and swab technique should be performed every 2 hours.<br />

The screen intervals will be agitated for approximately ½ hour and allowed to set for 1.5<br />

hours. This will be repeated every 2 hours throughout the day. The solution will then be<br />

allowed to set overnight. The agitation activities will then resume for another full day.<br />

These steps are repeated until the operator is satisfied that maximum benefit has been<br />

obtained.<br />

The pumping of the well is the same as described in the General Monitoring Well Development<br />

procedure if this is for a newly installed well. However, if the treatment is used to redevelop a well to<br />

increase flow rates then the following guidelines should be considered:<br />

1. If the well is a monitoring well then the purge water will be contained and the water quality<br />

monitored as described in the General Monitoring Well Development procedure. A test of<br />

the containerized water for parameters that are currently being monitored at the site will be<br />

performed.<br />

2. If the well being treated is a domestic/municipal well then the purge water can be discharged<br />

to the surface with the appropriate approvals and water quality parameters monitored as<br />

described in the General Monitoring Well Development procedure.<br />
