Environmental science and environmental engineering are the geoprofessions commonly associated with the identification, remediation, and prevention of environmental contamination. These services range from phase-one and phase-two environmental site-assessments – research designed to assess the likelihood that a property is contaminated and subsurface exploration conducted to identify the nature and extent of contamination, respectively – up through the design of processes and systems to remediate contaminated sites for the protection of human health and the environment. Environmental geology is one of the principal geoprofessions engaged in assessing and remediating contaminated sites. Environmental geologists help identify the subsurface stratigraphy in which contaminants are located and through which they migrate. Environmental chemistry is the geoprofession that encompasses the study of chemical compounds in the soil. These compounds are categorized as pollutants or contaminants when introduced into the environment by human factors (e.g., waste, mining processes, radioactive release) and are not of natural origin. Environmental chemistry assesses interactions or these compounds with soil, rock, and water to determine their fate and transport, the techniques to measure the levels of contaminants in the environment, and technologies to destroy or reduce the toxicity of contaminants in wastes or compounds that have been released to the environment. Environmental engineering is often applied to assess contaminated sites, but more often is used in the design of systems to remediate contaminated soil and groundwater. Hydrogeology is the geoprofession involved when environmental studies involve subsurface water. Hydrogeology applications range from securing safe, plentiful underground drinking-water sources to identifying the nature of groundwater contamination in order to facilitate remediation. Environmental toxicology is a geoprofession when used to identify the source, fate, transformation, effects, and risks of pollutants on the environment, including soil, water, and air. Wetlands science is a geoprofessional pursuit that incorporates several scientific disciplines, such as botany, biology, and limnology. It involves, among other activities, the delineation, conservation, restoration, and preservation of wetlands. These services are sometimes conducted by geoprofessional specialists called wetlands scientists. Ecology is a closely related environmental geoprofession involving studies into the distribution of organisms and biodiversity within an environmental context. Numerous geoprofessional disciplines contribute to the redevelopment of brownfields, sites (typically urban) that are underused or abandoned because they are or are assumed to be contaminated by hazardous materials. Geoprofessionals are engaged to evaluate the degree to which such sites are contaminated and the steps that can be taken to achieve the sites' safe reuse. Environmental engineers and scientists work with developers to identify and design remediation strategies and exposure-barrier designs that protect future site users from unacceptable exposure to environmental contamination resulting from previous uses of the site. Because these previous uses often resulted in degraded soil conditions and the presence of abandoned, underground structures, geotechnical engineers often are needed to design special foundations for the new structures.
