Spokane Aquifer

  • In Spokane Valley, the aquifer and the river are almost one and the same.  
  • The aquifer draws from the river.  Between the state line and the eastern Spokane Valley city limits, there are places where the river practically disappears during dry months as the aquifer draws what it needs.  http://www.spokaneaquifer.org/

  • Every day 7 plants discharge tens of millions of gallons of polluted waste water into the Spokane River, which drains into the aquifer.  Among these plants, 5 are sewage and 2 are industrial.  
What You Can Do
  • Request that signs be posted along the Spokane River warning people of the danger of swimming in and eating fish caught in the river?  Should people be informed of the water and soil’s dangerously high levels of PCB’s, lead, dioxins, arsenic, phosphorous, sewage, lead and cadmium?  Should people know that the Spokane Regional Health District encourages people to avoid the dusty soils along the Spokane River between Plantes Ferry Park and the Idaho state line that could be breathed in, or mud that could cling to clothing, advising river users to wash their hands and face thoroughly before eating, and to wash anything that comes in contact with shoreline soils before entering a residence?   (For more information, see the Spokane River and Aquifer under Environment on this website.)  
  • Do your part to protect The Spokane River and Aquifer.  Pollutants from many sources are robbing the water of oxygen, making it difficult for fish and aquatic plants to survive.  
  • Volunteer to change your habits and make a difference.  
  • Hook up homes on septic tanks to sewer when possible.
  • Dish Washing Detergent.  Do not use phosphorous-laden automatic dish-washing detergent—which was banned July 1, 2008.  A non-phosphorous powder dish washing detergent is acceptable.  
  • Washing Your Car.  Wash your car on your lawn using a biodegradable soap, so the water is absorbed by the lawn.  
  • Lawn Fertilizers.  Use environment-friendly lawn fertilizers.  You may purchase 50# bags of non-phosphorous fertilizer from the Greenacres Plant Food Center’s shop at 4301 W. Seltice Way in Post Falls; or Liberty Lake residents may purchase it from the Liberty Lake Sewer and Water District.
