Sinkholes are an essential part of our groundwater system. Sinkholes are like kitchen sinks, basins that will hold water, but
usually only for a short time. The water finds its way to the drain (conduit) then flows through the underground drainage system
toward the outlet, a spring. Because sinkholes drain rapidly, and because they have a direct connection with our groundwater (and
often our drinking water), we need to be careful what goes into them.

Sinkhole Facts - Inlets for the Underground Water Systemn (PDF) by the Watershed Committee of the Ozarks.
Karst Topography and Sinkholes are specifically mentioned by the EPA as locations to limit pesticide use. The EPA CAFO
rule also prohibits land application of manure within 100 feet of anydown gradient to a sinkhole. The Missouri Department of
Natural Resources requires that land application of manure must have a 300 feet separation distance from sinkholes, caves,
losing streams or any other connection between surface and groundwater.
