  1. Nonrenewable Groundwater Management Fundación Marcelino Botín Side Event – 5th World Water Forum Istanbul, Turkey, 20 March 2009 Michael E. Campana (aquadoc@oregonstate.edu) Director, Institute for Water and Watersheds Professor of Geosciences Oregon State University , USA and National Ground Water Association (www.ngwa.org) American Water Resources Association (www.awra.org) ICIWaRM – International Center for Integrated WaRM

  2. What Is Nonrenewable Groundwater? • Limited replenishment (recharge) • Limited replenishment, large • storage • Replenished, but over long time • scales • Water is being mined (extraction > • recharge) • ‘Decoupled’ from hydrological • cycle

  3. What Is Nonrenewable Groundwater? A Proposed ‘Definition’ “Nonrenewable groundwater is like pornography. I can’t define it, but I know it when I see it.” M. Campana (apologies to former US Supreme Court Justice Potter Stewart)

  4. (Non) Management of Nonrenewable Groundwater – New Mexico USA • In some USA states, NR GW often falls outside the realm of ‘renewable’ groundwater and eludes regulation. • Case in point: state of New Mexico, where non-potable groundwater deeper than 800 m that is isolated from drinking water aquifers cannot be regulated by state water officials. • Developers want this water, which will have to be desalted. One estimate:18,500 km3! • Rush to pump this water (>370 MCM/year) before New Mexico decides to regulate it. Chaos?

  5. Management of Nonrenewable Groundwater: New Paradigm? Unitization “…government-mandated unitization of groundwater … is a solution to excessive access and drawdown … a single “unit operator” extracts from and develops the reservoir. All other parties share in the net returns as share holders.” – Gary Libecap (2005) http://www.u.arizona.edu/~libecapg/downloads/ TheProblemOfWater.pdf

  6. Management of Nonrenewable GroundwaterUnitization - More The unitization concept, borrowed from the reservoir (petroleum) engineering field, is currently being developed by Todd Jarvis and Gary Libecap for groundwater resources. Stay tuned!
