Groundwater Hydrology
WHPA examines groundwater hydrology to evaluate the occurrence, distribution, movement, and quality of water in sub-surface geologic systems. Knowledge of groundwater is paramount in sustaining water supplies for drinking, agriculture, industry. A summary of our services include:
-
Hydrogeologic Characterizations - Aquifer Testing and Yield Analysis
- Wellfield Siting and Design
- Water Quality and Hydrochemistry
- Mining Impact Studies
- Pumping Impact Studies
- Conjunctive Use Evaluations
- Wellhead Protection Area Delineation
Watershed and Surface-water Hydrology
WHPA staff has expertise working with local governments and a comprehensive technical expertise in the areas of surface-water hydrology, water-quality sampling and analysis, and engineering. WHPA’s surface-water capabilities and services include:
- Watershed modeling and TMDL analysis
- Water-quality sampling and analysis
- Watershed management plans
- Contaminant assessment of receiving waters
- Evaluation of the increase in stormwater runoff due to future development
- Modeling to predict the effect of stormwater runoff on receiving water quality and recommend best management practices for improvement
Source Water Development and Wellfield Design
New sources of water need to be developed in areas already heavily tapped with competing users or with limited availability. Many utilities are seeing the treatment cost advantages of bank filtration and are converting from surface water intakes to groundwater, but now must ensure high volume groundwater yields to replace surface water.
WHPA hydrogeologists and engineers apply a comprehensive process to source-water development that combines geologic surveys, modeling, utility operation and maintenance considerations, and well-designed pump tests to fully characterize the aquifer and design a well field that will produce the maximum sustainable water yield at the lowest total cost.
