Water Resources

 

Meeting Surface And Groundwater Challenges

 
Surface and groundwater supply and quality issues can be complex and are surrounded by a variety of compliance regulations. Using our experience and technology, Norwest’s hydrology experts assess your situation and create a cost-effective, efficient strategic plan to address these challenges.
 
Norwest uses analytical and numerical modeling to evaluate surface and groundwater flow and quality. Using these techniques, Norwest professionals are able to analyze existing hydrogeologic conditions, and predict impacts of engineered interventions such as dewatering yield and drawdown. Modeling can be used for urban and rural stormwater runoff and water quality sampling.
 
Our internationally based team of experts has extensive experience in:

Water Resources

Surface water and groundwater investigations are critical components required for environmental assessments of resource development projects. Our services include baseline characterization and impact evaluation, soil and groundwater remediation, baseline monitoring, and groundwater fate and transport modeling. With combined strengths in hydrology and engineering, we look for cost effective measures to reduce or eliminate unfavorable impacts.
 
Norwest has provided Phase 1 and Phase 2 environmental site assessment services on behalf of both sellers and potential purchasers of industrial property since the mid-1980s. Our involvement with such clients includes carrying Phase 1 and Phase 2 assessments forward into remediation design and implementation. This broad background allows us to offer a deeper perspective on environmental assessments than many consultants focused solely on documentation alone.

Norwest has supported clients in developing site-wide water management plans that minimize operational delays associated with the need for an adequate water supply, storage or disposal of a surplus of water, management of storm runoff events and compromised water quality.
Norwest also designs and supervises construction of stream diversions and stabilized stream channels. Design procedures involve the application of geomorphic regime theory and the use of various surface water hydrology and erosion and sediment transport computer simulation programs.
 
Sophisticated hydrogeologic modeling provides projections on the effects of an operation on water supply, water quality and water use.
