Spokane Valley - Rathdrum Prairie Aquifer



Greenacres Landfill Closure
 
Several old landfills (dumps) exist around the periphery of the Spokane aquifer system.  All have shown evidence of contamination of the nearby ground water, and today steps are being taken to "close" the sites and preclude anymore degradation of the water quality in the aquifer.

The most recent landfill undergoing closure is the Greenacres site.  Check out the Spokane County Utilities web page describing this work.
