Most important public water supply aquifer in
southwest Missouri
Nearly all of the major water use in
southwest Missouri is from the Ozark aquifer
High-yield wells may be from 600 to gt1,700 ft
deep and typically contain 250 to 550 feet of
casing

Summary and Conclusions.

• Southwest Missouri has a lot of groundwater.
• Combined, the Springfield Plateau aquifer, Ozark
• aquifer, and St. Francois aquifer in the 13
  county
• area contain an estimated 116 trillion gallons.

• Major water users in the 13 county area report
• using about 25 billion gallons per year.

• Groundwater-level declines have occurred in the
• Ozark aquifer in areas where usage greatly
  exceeds
• recharge.
