Why It Matters
Tens of thousands of residents in two eastern Oregon counties may soon have their day in court over years of drinking water contamination tied to industrial operations in the region. A federal judge’s ruling this week keeps alive a lawsuit that could hold a broad group of corporations accountable for what plaintiffs describe as long-running harm to their water supply.
What Happened
U.S. District Judge Michael Simon on Friday denied a motion to dismiss in Pearson v. Port of Morrow, allowing the case to advance as a class action. The lawsuit, originally filed in U.S. District Court in February 2024, was brought by eastern Oregon residents and has since expanded in scope and legal standing.
The suit names 17 defendants. Among those who sought to have the case thrown out were the Port of Morrow, Lamb Weston, Madison Ranches, Threemile Canyon Farms, Portland General Electric, and Columbia River Processing. Judge Simon denied those dismissal efforts, finding that plaintiffs adequately stated claims for negligence, trespass, and private nuisance under Oregon law. The court also found the case has standing under the federal Resource Conservation and Recovery Act.
At issue is nitrogen-rich wastewater released by industrial food processors and data centers operating at the Port of Morrow, which plaintiffs allege has contaminated drinking water sources for communities in Morrow and Umatilla counties. A jury trial is scheduled to begin May 3, 2027.
The named plaintiffs are Michael Pearson, Michael and Virginia Brandt, and James and Silvia Suter. The class action is sought on behalf of residents across both affected counties. Attorney Steve Berman, who represents the plaintiffs, estimates approximately 45,000 residents could ultimately be included in the suit.
“This ruling is a significant win for the thousands of residents in Morrow and Umatilla counties who have waited years for safe drinking water and for someone to be held accountable,” Berman said.
Amazon Settlement in Progress
Amazon, named as an original defendant in the case, has been separately negotiating a settlement since March. A $20.5 million settlement figure has been reported in connection with those talks. The company’s data center presence at the Port of Morrow made it one of the more prominent names in the litigation, drawing attention to the role of the tech industry’s infrastructure buildout in local environmental disputes. The question of how industrial-scale data center operations affect surrounding communities is drawing scrutiny across the Pacific Northwest — a topic Oregon’s utility sector is also grappling with as it reconfigures who bears the cost of expanded energy demand.
By the Numbers
- 17 — total defendants named in the lawsuit
- 45,000 — estimated number of residents potentially covered by the class action
- $20.5 million — reported Amazon settlement figure
- February 2024 — date the original lawsuit was filed
- May 3, 2027 — scheduled jury trial start date
Zoom Out
The Port of Morrow case reflects a broader pattern of rural communities in the Mountain West and Pacific Northwest challenging corporate and industrial actors over environmental damage that local governments have struggled to address. Morrow and Umatilla counties have seen rapid industrial expansion in recent decades, with agricultural processing and data center facilities drawing significant investment — but also generating concerns about the long-term toll on land and water resources.
As rural Oregon contends with infrastructure and environmental pressures, state and local governments face growing demands on limited resources. Rural Oregon hospitals are already navigating uncertainty tied to potential federal Medicaid changes, adding to the financial strain many smaller communities are experiencing simultaneously.
What’s Next
With the motion to dismiss denied, litigation will move into the discovery phase. Amazon’s separate settlement negotiations remain ongoing. The remaining 16 defendants will now face the prospect of preparing for a jury trial set to begin in spring 2027 — a proceeding that could carry substantial financial and regulatory consequences for industrial operators in the region.
