Apparently the Florida Department of Environmental Protection complained to FERC that any drilling under our blackwater rivers would leak contaminants into the karst limestone that contains our drinking water Floridan Aquifer:

Update 2015-04-03: Additions now that FERC eLibrary is working, including third point below.

• Sabal Trail underestimated karst features—additional, more recent data available from agencies including LiDAR, potentiometric surface maps, and cave maps.
• Highest agency concern is associated with likely loss of drilling fluid associated with HDDs in limestone bedrock including at the Suwannee, Santa Fe, and Withlacoochee rivers.
• Drilling fluid loss would have an environmental impact; risk and magnitude of impact on groundwater, wells and springs should be based on updated, site-specific information.
