RPI’s broad natural resources expertise combined with a focus on quantitative analyses by highly experienced staff allow us to bring a unique and rigorous approach to ecological and environmental assessment projects. In undertaking projects, RPI combines interdisciplinary skills that include applied sciences, geospatial analyses, and resource knowledge to better understand and help solve specific environmental issues.

Our Services:

  • We develop approaches and tools that integrate stakeholder input and participation into innovative solutions to specific issues in urban, rural, coastal, and marine settings
  • We conduct robust ecological and geomorphological field surveys and interpret the results to inform and provide answers and solutions to the end users
  • We formulate and implement methodologies for assessing ecological and environmental impacts from spills or legacy contamination (e.g., heavy metals, priority contaminants) providing the scientific basis that supports site evaluations and inform appropriate actions

We have demonstrated experience in the following areas:

  • Ecological surveys in aquatic and terrestrial environments
  • Environmental Impact Studies and Assessments
  • Design and Implementation of Environmental Monitoring Programs
  • Non-Point Source Impairment Analysis and Remediation
  • Chronic and Emergency Marine Debris Mapping and Remediation
  • Vessel Grounding Impacts and Remediation
  • Water Resources and Floodplain Management
