ENVIRONMENTAL ASSESSMENT SERVICES

 

Our Environmental Assessment services focus on a wide range of topics, including various aspects of air, water, and soil pollution. These assessments have been conducted at locations throughout the United States. See some of our environmental assessment projects.

Climate & Air Quality

E&S Environmental provides services in many aspects of climate, air quality, and related effects on natural ecosystems. Our research and assessment activities focus on the following agents of climate change and air pollution stressors:

    • Carbon dioxide, methane, and nitrous oxide emissions
    • Atmospheric deposition of acidifying substances
    • Atmospheric deposition of nutrients
    • Particulate concentrations in the atmosphere
    • Ground-level ozone formation


We examine the effects of these stressors on a wide range of sensitive receptors, including those in remote wilderness and federal Class I areas. We monitor, assess, and/or model effects of climate change and air pollutants and investigate related topics areas, including:

    • Greenhouse gas emissions budgeting
    • Nature-based carbon dioxide removal (CDR)
    • Climate change vulnerability assessment
    • Soil and surface water acidification
    • Nutrient enrichment (eutrophication) of aquatic and terrestrial systems
    • Ozone impacts on vegetation

Water Quality

E&S Environmental provides water quality services for virtually all aspects of water quality work, from study design and protocols development to field sampling, data analysis, quality assurance, modeling, and interpretation. We assess the relative importance of point and nonpoint source pollutants and evaluate differences between natural conditions and ambient conditions, as influenced by human activities. Our water quality services include:

    • Watershed assessments and analyses
    • Monitoring
    • Mathematical modeling
    • Risk assessments
    • Watershed planning
    • Pollutant source identification
    • Temporal trends analysis
    • Interactions among water quality, land use, and watershed condition


We provide water quality services for lakes, streams, rivers, reservoirs, and estuaries. Our focus is on aquatic systems that range from pristine wilderness settings to surface waters that are influenced by urban, industrial, agricultural, and/or silvicultural land uses. We examine effects of the following types of water pollutants:

    • Nutrients
    • Acidifying substances
    • Bacteria
    • Sediment
    • Heat
