Water Supply Development and Evaluation/Aquifer Testing

The Montana Department of Environmental Quality and Montana Department of Natural Resources each have certain regulatory requirements in association with water supply development and aquifer testing.  Core Water can assist in locating, designing, developing, and providing construction supervision of groundwater wells and surface water diversion systems along with performing step and long-term aquifer testing, bringing pre-regulation water sources into compliance with modern DEQ standards, public water supply design, drawings, technical specification preparation, permitting, source water delineation and assessment report preparation, and construction oversight.  In difficult groundwater development areas, groundwater source identification can be investigated utilizing very low frequency (VLF) geophysics or resistivity and inverted-polarization geophysics.
