Caver's feet as he squeezes through passage

A high proportion of Appalachian agricultural production occurs on karst lands. The sinkholes and extensive cave systems of karst areas present water managers a challenge to protect water quality for the numerous small-farm families and rural communities of the region.  AFSRC is well known for its expertise in karst hydrology and water quality. In this photo from the 1990’s Dr. Gary Pasquarell (formerly, AFSRC Hydraulic Engineer) leads the way into a small, muddy cave passage that leads to a subterranean water sampling location.
