Amazon's $20.5 Million Nitrate Settlement: The First Big Tech Data Center Water Payout

The Lower Umatilla Basin in northeastern Oregon has one of the worst nitrate problems in the western United States. The state designated it a Groundwater Management Area decades ago, and nitrate levels have kept rising since. The primary historical sources are well documented and have nothing to do with computing: chemical fertilizer from large irrigated farms and wastewater from food processing plants, applied to land and leaching into the aquifer. Nitrates in drinking water are dangerous to infants and are linked to cancer risk in adults, and many residents of Morrow and Umatilla counties have relied on bottled water for years.

Amazon arrived in 2011, opening its first Morrow County data center in Boardman, and grew to 13 facilities in and around the basin. Data centers use large volumes of water for cooling, and the cooling process concentrates whatever is in the water. The plaintiffs' theory, as reported, was that Amazon sent concentrated wastewater to disposal systems run by the Port of Morrow, which applied it to farmland, adding to the nitrate load reaching the groundwater. In legal analysis of the case, the claims were framed under the federal Clean Water Act.

That framing matters. The plaintiffs did not argue that Amazon created the nitrate problem. They argued that a new industrial user layered its discharge onto an aquifer that was already failing, in a basin the state had already flagged. That is a theory available to neighbors of any data center that discharges to land or to a municipal system in a stressed watershed.

On March 31, 2026, plaintiffs' counsel filed a motion for preliminary approval of a $20.5 million settlement with Amazon Data Services in the U.S. District Court for the District of Oregon, Pendleton Division. Hagens Berman led the plaintiffs' team. Amazon denied wrongdoing and, according to reporting, agreed to settle to avoid protracted litigation.

The structure is the part communities should study. The funds are earmarked for private well and public water infrastructure projects in the basin: improving access to clean water for property owners, renters, and the broader community rather than cutting individual checks. That is common in environmental class settlements where the harm is shared across a region and the most useful remedy is fixing the water, and it is worth understanding before anyone near a data center imagines a settlement as a lottery ticket. The case continues against the remaining defendants, including the Port of Morrow, food processor Lamb Weston, and several large agricultural operations. In August 2026, one of those, Madison Ranches, agreed to a separate $6.2 million settlement.

Until this settlement, the tracker's water entries were mostly disputes rather than payouts. The Dalles records case forced Google's water use into the open but paid no one. The Louisa County suit against Amazon in Virginia is a single homeowner's pending well claim. The Newton County suit against Meta in Georgia, filed in late August 2026, is four families alleging construction fouled their wells. The Oregon case is different in kind: a certified-class-scale claim, a defined geographic harm, a federal forum, and a settlement with a dollar figure attached.

It is also different in mechanism. The Georgia and Virginia cases are about construction and site disturbance. The Oregon case is about operations, specifically what happens to cooling water after it leaves the building. As data centers multiply in water-stressed regions, that operational discharge question, where does the concentrated wastewater go and what is already in the aquifer it reaches, is likely to generate more claims than construction ever will. Our guide to data center water contamination claims covers both mechanisms.

If you live in a basin with a known groundwater problem and a data center is discharging into it, the Oregon case is the template, and its lessons are practical:

• Find out where the water goes. Discharge permits, port and utility agreements, and land application records are public. The Oregon plaintiffs' case was built on the Port of Morrow's disposal arrangements.
• Know your basin's status. A state groundwater management designation or a history of nitrate advisories is the context that turns a data center's discharge from a footnote into a claim.
• Test your well and keep the results. Nitrate tests are inexpensive, and a series of them over time is far more persuasive than one.
• Think regionally. The Oregon case was a class action because the harm was shared across two counties. If your neighbors' wells show the same trend, the case is bigger than your house.
