The Lower Rio Grande Dilemma• Persistent drought and a permanent shift to a more
arid climate;• Highly interactive surface water and groundwater;• Long-term water policy issues;• Water is necessary for economic development.• Litigation: Texas and US v. New Mexico on the Rio
Grande Project.

Project Objectives:• Assess potential for brackish water desalination in
the Santa Teresa area;• Characterize source water and geohydrology,
treatment technologies, and disposal alternatives;• Integrate with prior and ongoing planning efforts;• Explore binational potential for water supply to San
Jeronimo in Mexico;• Produce a Preliminary Engineering report and plan
path forward.
