Emergency Water Supply Well

Seattle Childrens Hospital
Seattle, Washington

Hart Crowser located a groundwater source and developed an emergency water supply well for the hospital. The project involved finding a water supply in an urban environment with no traditional hydrogeologic data below 300 feet. A productive water-bearing zone was located at 650 to 700 feet. We used computer modeling to evaluate the capture zone of the well. Aquifer testing and water quality sampling indicated that the water source was of sufficient quantity and quality to meet the emergency drinking water and firefighting needs of the hospital.

 

Water Resources On-Call Services

Washington State Department of Ecology
Washington

Hart Crowser is assisting the Washington State Department of Ecology with water rights permit processing and other water resource-oriented consulting services. Projects have included developing a conceptual hydrogeologic model, assessing groundwater availability, and assessing impacts of additional water usage on existing water users and stream flows.

 

Groundwater Modeling Code and Input Parameter Evaluation

Washington State Department of Ecology
Hanford Reservation, Hanford, Washington

Ecology is evaluating the technical applicability of the US Department of Energy's proposed groundwater flow model code, STOMP, and the appropriateness of proposed input parameters for selecting cleanup remedies at the 200 West Area of the Hanford Reservation. Hart Crowser evaluated proposed groundwater infiltration rates based on lysimetry, numerical modeling, and chloride mass balance, and made recommendations to Ecology.


Private Ranch Aquifer Assessment

Washington

Hart Crowser completed a hydrogeological assessment and critical aquifer assessment of the proposed expansion of a private recreational development in the Cascade Mountain foothills. The development obtains drinking water from an area with poor water quality. We reviewed area water resources and suggested several alternatives sources that may provide water for the development without requiring special treatment.
