Water Resources & Hydrogeology

Our expertise in evaluating complex hydrological systems has earned us the respect of clients and regulatory agencies.

The services we provide include all aspects of water resource investigations for both surface and groundwater systems, water rights, and public water supply design and certification. We also provide client support to develop new supply sources or to expand existing systems. Our engineering staff can design, cost, and oversee construction of pumps, lift stations, piping, and other aspects of distribution systems. Our team is experienced with Montana’s regulatory requirements and the Montana DEQ and DNRC staff in Helena and regional offices.

Sampling groundwater to assess the performance of the Point Ruston site cap.

Our experience ranges from basin-wide groundwater investigations to siting and construction of individual wells and includes over 100 sites with contamination problems such as metals, arsenic, petroleum products, pesticides, PCBs, solvents, cyanide, and a variety of other organic and inorganic compounds. These investigations have been conducted at abandoned mine sites, oil refineries, smelters, railroad facilities, pipelines, manufacturing sites and waste contaminant facilities. A number of these sites are CERCLA/RCRA (Superfund) sites.
