Areas of Emphasis

Wellhead Protection Plan

Cover221pxThe Spokane Aquifer Joint Board developed a comprehensive wellhead protection plan that includes a technical characterization and assessment of the hydrogeologic setting of the Spokane Aquifer and provides the basis for wellhead protection areas. The wellhead protection areas serve as the foundation of the program, defining the areas for contaminant source inventory, risk assessment, contingency management, public education and possible groundwater protection ordinances. The report was prepared January 2000, by CH2MHill and funded in part by the Washington State Department of Ecology Centennial Clean Water Fund Grant No. G9600216, and the Spokane County Water Quality Management Program.

Education and Awareness

SAJB develops and implements a long-term education and awareness campaign targeted at citizens living and working over the Aquifer.  Aqua Duck, Defender of the Aquifer, can be found at school and community events with his six adventure comic books and new activity book.  The SAJB Program Manager accompanies Aqua Duck at local events, talks with citizens about things we can all do to protect the aquifer and distributes a variety of educational publications such as the Aquifer Atlas.

SAJB works with West Valley Outdoor Learning Center and KSPS to provide aquifer curriculum and lessons to public and private school teachers and students across the Spokane Valley Rathdrum Prairie Aquifer region in both Washington and Idaho.  Try one of our Virtual Tours or contact us for an upcoming event.

Household Contaminant Disposal

SAJB provides information to residents about the proper disposal of household contaminants, options for safer alternative products and collection locations provided by the Spokane Regional Solid Waste System.

Proactive Business Assistance

SAJB partners with eight local agencies and non-profits to sponsor the Spokane EnviroStars program which provides technical assistance and information to small businesses for contaminant disposal methods and procedures. If your business generates less than 200 pounds of dangerous waste or 2.2 pounds of acute hazardous waste per month, you are considered a small quantity generator (SQG).  SQGs who properly manage their hazardous and dangerous wastes are eligible for EnviroStars certification and recognition.  Contact us to request Local Source Control technical assistance and EnviroStars certification or go to to get more information.

If your business generates more than 200 pounds of dangerous waste or more than 2.2 pounds of acute hazardous waste per month your business is considered a medium or large quantity generator MQG or LQG. For technical assistance call the Washington State Department of Ecology at 509-329-3409 or visit their website.

Potential Contaminant Source Inventory

SAJB develops and maintains a regional potential contaminant source inventory database. Under current Washington State regulations for wellhead protection, every two years water purveyors are required to notify potential contaminant sources (businesses) that are located within defined wellhead protection areas. This is a reminder to the business owners of their location over our “sole-source” Aquifer, and the need for everyone to protect this precious resource.
