All monitoring wells must be developed as follows:

1. The waiting period for monitoring well development after completion of well installation shall allow setup of sealants.

2. The monitoring well must be developed utilizing procedures that are compatible with the monitoring objective and that do not adversely impact well integrity. Development of the monitoring well must include at least three cycles or last for approximately one hour until the water is free of sediments or stabilizes, whichever occurs first. Stabilization occurs when successive measurements of indicator parameters, such as instrument readings for turbidity or specific conductivity, taken from separate well volumes, are within ten percent.
