Ecological Risk Assessments

EAS has an important role in the development and execution of ecological risk assessments on the Hanford Site. Our experts are highly regarded by the regulators and stakeholders as a resource for collecting unbiased environmental data to support the decision-making process. This expertise is also being applied to areas outside Hanford.

Our work includes:

  • designing sampling plans
  • collecting environmental samples
  • designing impact assessment databases
  • developing mitigation alternatives
  • supporting special research needs
