Section 33.1-18-02-07 - Borehole and monitoring well documentation1. A written log must be kept which records the depth below ground surface of the boundaries of all strata encountered when drilling a borehole. Each stratum encountered must be described using generally accepted geologic terminology.2. The certified monitoring well contractor must provide a monitoring well completion report to the board of water well contractors on forms available from or acceptable to the board within thirty days after the well has been installed. A completed report must include project and location, date of drilling, logger's name and title, well number or borehole number, drilling method and fluids used, borehole diameter, total depth, decontamination procedures, and a lithologic description as provided by subsection 1. Additional information, the availability of which is dependent upon the drilling method used, should also be provided and includes moisture content, fractures, and depth at which water was first encountered. A completed report must also include certified monitoring well contractor's name and license number; riser material; screen material and screen slot size, length, and placement; filter pack materials; riser and screen cleaning and installation procedures; sealing materials, placement and installation procedures; well development procedures; and any installation conditions which affected well construction.3. When completion reports are required by the department as a matter of fulfillment of its regulatory functions, the reports must include the information required by subsections 1 and 2; a detailed drawing of each well, including dimensions, as part of the well driller's report; and a map drawn to a specified scale showing the locations of all monitoring wells with an accuracy of three feet [0.914 meter]. The map must include manmade structure boundaries, any pertinent property boundaries, a north arrow, the location coordinates and elevation of all permanent benchmarks, the horizontal position of each monitoring well and its survey coordinates, the vertical elevation of the top riser referenced to the nearest benchmark to an accuracy of 0.01 feet [0.003 meter], and the respective identification number for each well.N.D.
