A settlement totaling 20.5 million dollars has been reached in a class action lawsuit against Amazon Data Services, Inc. (ADS or Defendant). The claims state that millions of gallons of wastewater from ADS data centers and operations of other facilities in the Lower Umatilla Basin Groundwater Management Area (LUBGWMA) in Morrow and Umatilla Counties in Oregon contribute to nitrate pollution in the groundwater. The claims also state that nitrates pose dangers to human health and the environment, and that drinking nitrate-contaminated water creates serious health risks. Defendant denies the claims and any wrongdoing or liability.

The lawsuit is known as Pearson et al. v. Amazon Data Services, Inc., Case No. 2:26-cv-00633.

Who is included in the Settlement? The Settlement Class is defined as all Persons who currently own or rent property or reside in the Lower Umatilla Basin Groundwater Management Area.
