MRPC cleanup continues at sinkhole that flows to Ha Ha Tonka Spring
Some 15,340 pounds of garbage was removed from the Goodwin sinkhole in Laclede County during a volunteer cleanup weekend, held Nov. 3 and 4, as the effort to clean the sinkhole continues.
A dye trace performed by the Missouri Department of Natural Resources (MDNR) Division of Geological Land Survey showed water from the sink drains into Ha Ha Tonka Spring, which empties into Lake of the Ozarks.
“The main reason we are trying to clean it out is because of the water quality issues that affect Ha Ha Tonka,” said Tammy Snodgrass, Meramec Regional Planning Commission (MRPC) Environmental Programs Manager.
According to Snodgrass, this is because the sinkhole has been used as an illegal dumping ground for decades. As water filters through trash and garbage, it picks up contaminants, which is referred to as nonpoint source pollution. When nonpoint source pollution occurs in Missouri’s unique Karst topography–characterized by sinkholes and caves where the land has been shaped by underground springs–portions of that pollution travel through the groundwater system and find their way to Missouri’s lakes, streams and, sometimes, drinking water sources.
MRPC staff setup a display board with educational information about non-point source pollution for volunteers to view during the most recent cleanup effort.
