Description Procedure (MTDOT Soil Mechanics Bureau STP-2 dated May 1, 1975, as amended). Rock should be described using standard geologic terms for the rock type encountered in the borehole. Well_ v1 Contains basic information for each well and is required if the location EDD contains wells. Important information captured in this EDD include the well owner, measuring point elevation, depth of the well, whether or not the well includes a sump, pump information, stickup height, and installation date. Data Providers Field Personnel Once per location This EDD will include all wells installed at the site and shall be submitted when well installation is complete and when the datum value of the well is changed. For example, if a well is converted from stickup to flush-mount and the inside casing is cut down then the datum value (top of casing elevation in this case) has been changed and the Well EDD would be submitted to document this change. Following is a description of the fields in this section: WellConstruction_v1 Contains well construction information, such as casing length, screened interval, backfill information, and other construction details. Data Providers Field Personnel Once per location or when the surface completion or top of casing elevation or datum value is changed For each well on the Well_v1 EDD section multiple records describing the components of a well, such as the collar, casing, screen and materials used can be placed in the WellConstruction_v1 EDD section at their respective depths for each well. The following fields are required by MTDEQ for documenting well construction details in the WellConstruction_v1 EDD section: sys_loc_code – Sample location id for a well that must be unique within a facility
