Developers propose produced and brackish water options; residents press for testing and protections

Developers speaking to Brewster County officials described multiple water options for cooling and operations, including treated produced water from oilfields, brackish groundwater and testing the locally cited Hobie trough aquifer. Pacifico said it would avoid municipal water supplies and that initial fills for closed‑loop cooling systems often use purified water followed by periodic top‑ups.

"We'd like to look into produced water, cleaning up the produced water because that's not a—that's not a whole lot for us and using that if we can," a presenter said while outlining options for water sourcing and treatment. He added that proving subsurface resources would require drilling and testing and that the team had noted existing wells on the candidate ranch parcels.

Residents asked for specifics: how many test wells would be drilled, what quantity of groundwater would be used for construction and operations, and whether any pumping could reduce flows to springs or wells used for ranching and tourism. At least one commenter pointed to studies done elsewhere (San Angelo was cited) suggesting recharge may exist in local formations but said independent verification is needed.

Why it matters: Brewster County is arid and relies on groundwater and tourism; any large consumptive use or the permanent presence of infrastructure (roads, man camps) could have lasting effects. Developers said they would design to minimize impacts and that some project water demands can be lower than other regional industrial uses, but multiple residents urged rigorous, independent hydrologic review before any approvals.

The court noted it would take public input and further information as surveys and tests are completed.
