Environmental Groups, Tribes Sue Over Trump-Era Mojave Pipeline Approval
Environmental groups and tribes have sued to block renewed approval of a Mojave Desert water pipeline.
Why it matters: Legal conflicts over this pipeline highlight critical tensions in land use, environmental protections, and administrative policy reversals. The case signals ongoing challenges for legal professionals navigating these changing regulatory landscapes.
- On July 9, 2026, BLM approved Cadiz Inc.'s plan to convert a 220-mile gas pipeline into a water pipeline.
- Cadiz plans to extract up to 25,000 acre-feet of groundwater annually from the Mojave Desert aquifer.
- Environmental groups and Native American tribes filed suit citing harm to desert ecosystems and sacred tribal sites.
- This approval reverses the prior Biden administration withdrawal, reflecting sharp policy shifts in water resource management.
The Bureau of Land Management (BLM) approved on July 9, 2026, a controversial proposal by Cadiz Inc. to repurpose a 220-mile natural gas pipeline into a water pipeline. This water pipeline is designed to transport groundwater from the Mojave Desert, with plans to extract up to 25,000 acre-feet annually from the desert aquifer.
Cadiz Inc. hailed the approval as a significant milestone. Susan Kennedy, Cadiz Chair and CEO, said the project is now entering the construction stage after extensive planning and environmental review.
However, the renewed approval has reignited fierce opposition. Environmental groups and Native American tribes filed a lawsuit challenging the approval, arguing the project threatens the Mojave Desert’s delicate ecosystems and sacred tribal lands. Chance Wilcox, California Desert Associate Director at the National Parks Conservation Association, condemned the project as "groundwater mining" that would drain the desert’s rare springs and wildlife habitats.
This legal challenge underscores ongoing conflicts between federal land management policies and environmental conservation advocates. The approval under the Trump administration reversed earlier withdrawal actions taken by the Biden administration, reflecting deep administrative divisions on water resource exploitation in arid regions.
The case exemplifies the complex legal landscape around land use, federal oversight, and environmental protections, all playing out through repeated shifts in regulatory stance and subsequent litigation.
By the numbers:
- July 9, 2026 — BLM approval date for pipeline conversion
- 220 miles — length of Cadiz pipeline to be converted
- 25,000 acre-feet — proposed annual groundwater extraction from Mojave Desert aquifer
