Monitoring well development
Cite as N.D. Admin. Code ยง 33.1-18-02-09
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.
