Water Resources
Where will the water come from, and how much will be needed?
Status: 🟡 Partially Answered
Current Information
The proposed facility plans to use groundwater in its cobalt sulfate production process.
Earlier project documents estimated total water demand at approximately 140,000 m³/month, or about 37 million gallons/month. The project’s more recent July 27, 2026 announcement states that approximately 70% of process water is expected to be recycled and reused, resulting in estimated net freshwater consumption of approximately 34 acre-feet/month, or 408 acre-feet/year.
These figures appear to describe different measures: total process-water demand versus net freshwater consumption after recycling.
The project site is located within the Wellton-Mohawk Subbasin of the Lower Gila Aquifer, and groundwater remains the proposed source of make-up water. According to the Yuma Sun (May 31, 2026), WMIDD contributed approximately $95,000 toward drilling and evaluating the project’s test well.
Remaining Questions
- What is the expected actual groundwater withdrawal rate from the production wells during normal operation?
- What is the expected maximum/peak pumping rate?
- How does the approximately 840-gpm requirement identified in the groundwater investigation relate to the 408 acre-feet/year net-freshwater figure?
- Does the 408 acre-feet/year estimate apply only to the initial production capacity?
- If production capacity increases in the future, what would the corresponding groundwater withdrawals be?
- Could higher water-recycling rates be technically and economically feasible?
- What role, if any, will WMIDD have during facility operations?
Groundwater Protection
How will the aquifer be protected?
Status: 🟡 Partially Answered
Current Information
- The Arizona Department of Water Resources (ADWR) Well Registry confirms that the proposed project is located within an area containing numerous registered groundwater wells serving a variety of uses, including irrigation, domestic, livestock, industrial, and other groundwater users.
- The Well Registry identifies registered wells (55-240408, 55-302618, 55-303321) and their reported uses but does not determine whether the project’s wells are hydraulically connected to surrounding groundwater users. Establishing hydraulic connectivity requires hydrogeologic analysis beyond the scope of the Well Registry.
- ADEQ has stated that an Aquifer Protection Permit (APP) is required for any facility with discharges that have the potential to impact an aquifer.
- To date (7-20-2026), ADEQ has confirmed that no APP application has been submitted for the proposed EVelution Energy facility. ADEQ has also confirmed that no Determination of Applicability has been requested to that date.
- Groundwater investigations for the proposed project are ongoing.
Remaining Questions
- What are the results of the groundwater investigation?
- Is the aquifer hydraulically connected to groundwater used by agriculture, municipal users, or other groundwater users in the region?
- Will wastewater be discharged, evaporated, transported off-site, or retained in waste materials?
- How will water-treatment residuals (such as concentrated brine or other treatment by-products) be managed and disposed of?
- What is the anticipated geochemistry of the tailings and other process waste materials that could affect groundwater?
- How will changes in recycled process-water chemistry be monitored and managed over time?
- What groundwater monitoring will be required?
- What spill prevention and containment measures are planned?
- Which groundwater protection permits have been submitted or approved?

Methodology and Assumptions
Preliminary estimates are based on publicly reported revenue, assumed operating margins, and general tax-revenue assumptions. They are not official company, county, or state fiscal-impact figures.
The purpose of this question is not to determine whether the project has value, but to better understand how long-term public benefits compare to the scale of investment, public support, resource use, risks, and community involvement associated with the project.
Additional discussion is available on the Who Benefits? page.
What long-term benefits will remain in Yuma County?
Status: 🟡 Partially Answered
The proposed facility is expected to receive considerable public support through permitting, infrastructure, public services, groundwater evaluation, public financing mechanisms, and other forms of government involvement.
What measurable long-term benefits will remain in Yuma County and surrounding communities, including permanent jobs, wage levels, tax revenues, community investment, workforce development, and other economic benefits?
Current Information
Publicly available information references:
- Approximately 60 permanent direct jobs
- Approximately 300 indirect jobs (earlier estimates)
- Approximately 1,225 construction jobs
- Approximately $55 million in construction income
- Up to $300 million in construction and development impact
- More recent reports reference approximately 3,300 direct, indirect, and induced jobs and more than $750 million in economic-development impact.
Public sources reference approximately 60 permanent direct jobs at the processing facility.
Additional jobs may be associated with:

But the number of long-term local positions has not yet been clearly documented.
These figures represent broader economic-impact estimates that include construction activity, supplier spending, and multiplier effects throughout the economy.
They should not be interpreted as permanent employment, direct local government revenue, or direct community benefit.
Remaining Question
- How many of the reported indirect jobs are expected to be permanent local positions in Yuma County after construction is complete?
- Some may be associated with operating and supporting the facility itself,
- while others may reflect broader economic benefits to the surrounding community.
