M&A was hired by an energy company to identify a water supply for a proposed green hydrogen facility. We studied the hydrogeology of the underlying aquifer and evaluated water supplies that are physically and legally available in sufficient quantities.

Based on existing hydrogeologic data, we identified favorable locations on the project site for developing a long-term reliable groundwater supply.


Hydrogen production at a solar-powered green hydrogen generating facility is projected to be 120 metric tons per day. To meet projected water demands, the facility will need a long-term reliable water supply of 780 acre-feet per year.


Water Supply & Recharge

  • Compiled and analyzed existing hydrogeologic data
  • Assessed hydrogeologic conditions and potential for development of needed groundwater supply
  • Inspected existing well and sampled for water quality analysis

Water Policy & Water Rights

  • Assessed potential alternatives to local groundwater supply, including imported groundwater, long-term storage credits, Colorado River water, effluent, and storm water
  • Assessed legal and regulatory constraints for potential water sources
  • Compared potential alternatives in terms of cost and ease of water rights acquisition, need for wheeling contract with CAP, infrastructure, and long-term reliability

Groundwater Modeling

  • Estimated aquifer hydraulic properties based on well-specific capacity data and lithologic data
  • Conducted analytical modeling using AQTESOLV to project drawdown and sustainable pumping rate with image wells to represent negative boundaries
  • Adjusted projected drawdown for water table conditions, cyclical pumping, and well efficiency
  • Used model results for preliminary assessment of water supply
