Clogged "pores" are keeping the Ogallala Aquifer down
March 2, 2009
An organization called the Playa Lakes Joint Venture
is promoting its work throughout the Great Plains aimed at protecting the temporary lakes and seasonal wetlands called playas
that help channel rainfall into the groundwater table, which throughout their region serves to recharge the Ogallala Aquifer. The organization is working to raise public awareness of the problem of sedimentation, through which soil and sand runoff is clogging the "pores" in the ground by which that precipitation makes its way to the groundwater table. Sedimentation can be the result of poor agricultural land management, as well as the result of runoff from construction sites, roadways, and other urban features. Products like turbidity curtains
can help prevent sedimentation and protect natural waterways.
