MARK YINGER, P.G.
Hydrogeologist

Mr. Yinger is a hydrogeologist specializing in water resource evaluation and development. He has extensive experience in hydrogeologic assessment from the scale of an entire drainage basin to the issues associated with a single well. Clients for this work have included the State of Washington in its effort to inventory state water resources, public and privately owned drinking water suppliers, and individual corporate water well owners. Mr. Yinger is capable of bringing the most effective technologies available to address the needs of a client.

Project Experience:

  • WRIA-29 -- Groundwater resource study, Envirovision: Responsible for the evaluation of groundwater resources in the Wind River, Little White Salmon and White Salmon Rivers basin of Washington. These three basins constitute Region-29 as defined by the Washington State Water Resource Inventory Act.
  • Irrigation well, Paul Limmeroth, Limmeroth Ranch: Specified the location for a new irrigation well in the Eightmile Creek area south of The Dalles, Oregon. The well is very productive and will be used to irrigate a cherry orchard and alfalfa. When developed the well will yield 2,000 to 2,500 gallons per minute.
  • Groundwater resource study, SDS Lumber Company: The purpose of this project was to evaluate the availability of groundwater for a planned natural gas fired steam-turbine electrical generation plant. The study involved the development of a conceptual hydrogeologic model based on: geologic field mapping, interpretation of area well logs, published and unpublished geologic literature, aerial photographs, and satellite images.
  • Geothermal well, North Bonneville Hot Springs Resort: Involved in a study to select a location for a geothermal well to replace an old shallow well that appears to have been damage by a large natural gas explosion. The challenge was to locate a probable fault zone buried beneath the Bonneville Landslide deposits. To date the work involved: interpretation of published and unpublished geologic and geothermal exploration literature, extensive geologic field mapping and a seismic survey.
