Subd. 20a. Water supply well.
"Water supply well" means a well that is not a dewatering
well or monitoring well and includes wells used:
(1) for potable water supply;
(2) for irrigation;
(3) for agricultural, commercial, or industrial water supply;
(4) for heating or cooling;
(5) as a remedial well; and
(6) for testing water yield for irrigation, commercial or industrial uses, residential supply, or
public water supply.
Subd. 21. Well.
"Well" means an excavation that is drilled, cored, bored, washed, driven,
dug, jetted, or otherwise constructed if the excavation is intended for the location, diversion,
artificial recharge, or acquisition of groundwater. Well includes monitoring wells, drive point
