CONCERNS

• The karst here is treated as discrete points in
  need of protection
• The entire area is susceptible and unique.
• We shouldnt be identifying point features to
  protect we should be identifying large areas to
  protect.

AQUIFER COMPARISON

• SAND AND GRAVEL
• Small pore size mechanically filters
• Torturous flow paths slow water
• Contaminants dont travel far
• Remediation possible

• KARST
• No filtration takes place
• Fractures and conduits yield fast water
  velocities
• Contaminants are quickly broadcasted over large
  distances

  predicted to continue.

• Multiple jurisdictions with no coherent plan or
  vision for the region

• TxDOT and River Authorities building
  infrastructure without local accountability
