The water resources group provides world-class expertise using innovative approaches and solutions to help clients understand complex water resource issues. RESPEC scientists and engineers conduct holistic and comprehensive physical, biological, and chemical evaluations. We identify sources of pollution and their impacts; develop practical, cost-effective goals and strategies; and assess progress toward goals after implementation. Modeling and statistical analyses are part of the many tools RESPEC uses to enhance the understanding of the watershed process and to enhance our client’s decision-making process. They are useful in quantifying contributors, including point sources for industry and municipal effluent, urban runoff, agricultural lands, and forested lands. Historic and geospatial data regression and nonparametric analysis are used to develop an understanding of the critical processes within the watershed. Models can be developed using existing programs. The models are calibrated and validated with historic data. The models can then be exercised to predict future conditions and test effectiveness of BMPs. RESPEC takes full advantage of emerging technology, models, geospatial information, and hardware to perform cost-effective, credible, and easy-to-understand analysis of the watershed.

Dewey-Burdock Uranium ISR Permitting, Edgemont, South DakotaRESPEC was involved in multiple aspects of the permitting process of Powertech’s Dewey-Burdock project. As part of baseline investigations, RESPEC produced stand-alone reports about meteorology, surface water hydrology, groundwater hydrology, water rights, and geology, in addition to many other permit ... |
City of Sioux Falls TMDL Project A bacteria Total Maximum Daily Load (TMDL) assessment is being completed on four reaches of the Big Sioux River from Dell Rapids to Brandon, South Dakota. The project area is unique in that it encompasses a mixture of rich agricultural land as well as the densely populated area within and ... |
Cheyenne River TMDL Project The Cheyenne River in western South Dakota is currently listed as impaired for total suspended solids (TSS) and fecal coliform bacteria. A Total Maximum Daily Load (TMDL) assessment project for the Cheyenne River Watershed in western South Dakota was initiated in the spring of ... |
Rapid City Stormwater Quality Designs and Planning Preparation Training The city of Rapid City is a Phase II National Pollutant Discharge Elimination System (NPDES) community, required to have an MS4 permit. As part of their NPDES permit activities, the City sponsored training sessions for local engineers, home builders, developers, and City staff focused on erosion control, primarily for construction ... |
Dewey-Burdock, SD - Groundwater Characterization & Modeling RESPEC has worked on several aspects of groundwater characterization for a proposed in situ recovery uranium facility in the southwestern Black Hills. As in situ mining occurs in the saturated Inyan Kara aquifer, used for drinking water throughout the area, groundwater became the most important aspect of this permitting project. ... |
Black Hills Development Suitability MappingA slope stability analysis was performed to create factor-of-safety maps to assess slope failure susceptibility because of future land development in the Hermosa NW and Hermosa 7.5 minute quadrangles in Pennington County.... |
