There’s a reason Valdosta’s water wells are 400 feet deep. Its earlier, shallower wells were sucking up Withlacoochee River water that still leaks into groundwater. Should we risk a fracked methane pipeline digging under that same river and possibly causing more sinkholes and underground movement of contaminants, some perhaps coming from the pipeline itself or its demands for pressure testing water?

The Connection Between Surface-Water Quality and Ground-Water Quality in a Karst Aquifer

The Upper Floridan aquifer, which is the sole source of water supply for Valdosta, Georgia, and much of the surrounding area, receives large volumes of direct discharge from the Withlacoochee River through sinkholes in the streambed or off-channel. A highly interconnected conduit system has developed Continue reading →
