Desalination of Brackish Water in the Southern Mesilla Valley:

Preliminary Planning

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.

Desalination of Brackish Water

• US Bureau of Reclamation funding $400k + $478k cost share (NMWRRI), Jan 2019 – Dec 2020

• Co-PIs: Dr. Pei Xu, Dr. Sam Fernald, Dr. KC Carroll• Geohydrology: Dr. John Hawley, PG• Consultant: Ed Archuleta, PE

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.

What’s Next?

• Stakeholders meeting, project implementation; • Pilot testing, demonstration of concept• Student Capstone treatment plant design projects• Explore binational potential: USIBWC, Mexican

partners• Note to self: Get quarterly report to Cathy
