EIS Support

Hydrogeologic expertise for projects that require an EIS or an EA


M&A has extensive experience investigating the impacts — direct, indirect, and cumulative — to the quantity and quality of water resources. We typically work as part of a multidisciplinary team to meet NEPA-mandated requirements for clients who want to develop new facilities or expand existing ones. We have prepared the water resource portions of EIS submittals for recreational facilities and proposed developments, often using hydrologic models, innovative field characterization approaches, and remote sensing to document existing or historical conditions and assess impacts. M&A is also a valuable asset to the public input process; we interface with federal, state, local, and tribal agencies, as well as with special interest groups. Our public presentations are clear, objective, and defensible, communicating complex concepts to a range of audiences.

  • Designing methods for assessing impacts
  • Designing and implementing data-collection programs
  • Preparing reports, submittals, and responses to public comments
