Explore environmental careers.
Environmental geologists study the earth with the specific focus of understanding human interactions with the land, particularly as a means to predict or anticipate geological issues and provide information to help minimize impacts on the environment. They work on a variety of projects and can be involved in studying earthquakes, erosion, watershed management, mineral resources, and landfills. Environmental geologists also examine the effects of urban and industrial expansion and are vital to finding successful strategies for minimizing the negative effects of growth.
At a glanceImagine you are standing on the bank of a shallow, fast-moving creek, watching carefully as one of your colleagues manoeuvres a mechanized auger to extract a core sample from the bank. You are an environmental geologist working on a project to construct a 300-kilometre underground pipeline that will carry crude oil from northern wells to refineries farther south.The pipeline must cross a number of environmentally sensitive areas, such as this creek, and the regulatory process requires that all environmental issues be addressed before construction begins. In order to do this, the pipeline’s builders have assembled a multidisciplinary team of geologists, biologists, and geographers to study the proposed pipeline route and determine its potential impact on the environment. The team will also make recommendations on ways to mitigate the pipeline’s impact and avoid serious problems.As an environmental geologist, you specialize in the rock and soil that this pipeline will be buried under, and the team will rely on your expertise to evaluate geological conditions along the proposed route. Hundreds of core samples will be taken from sites along the route and analyzed for particular characteristics. For example, you will take the core sample from the creek bed to your lab and analyze its soil and rock composition. You will look at particle size and porosity, which is a measure of the space taken up by pores in rock and soil.You will also measure the core samples’ hydraulic conductivity. This very important measurement gives you an idea of how quickly liquid moves through the soil or rock around the pipeline. Should crude oil ever leak from the pipe, you can estimate how far and how quickly the leak will seep before it is contained. This is particularly important around sensitive areas such as the creek: if the hydraulic conductivity of these samples is too high, barriers must be installed to ensure that a crude oil leak doesn’t seep into the creek. You may also recommend that barriers and extra fill be used in areas where stability is an issue so the pipeline isn’t cracked by pressure or movement in the earth. Before the 1.5-metre trench is dug, you will be responsible for making certain geological conditions for the route are mapped and assessed so any environmental concerns can be properly addressed.
Job dutiesDuties vary significantly from job to job, but the following list includes typical job duties one might encounter as an environmental geologist:
- Conduct geological surveys and field studies.
- Collect and analyze rock and core samples from field studies, drilling, and test programs.
- Collect soil and sediment samples for geochemical analysis.
- Study the effects of erosion, sedimentation, and tectonic deformation.
- Record and interpret geological information from maps, reports, boreholes, aerial photos, satellite imagery, and geochemical surveys.
- Assemble and operate environmental cleaning apparatus, for example soil vapour extraction systems.
- Assemble and calibrate air analyzing instruments.
- Collect samples of contaminated soils.
- Study and identify natural risks such as volcanoes, earthquakes, and mudslides.
- Prepare geological maps, cross-sectional diagrams, and reports based on fieldwork and laboratory research.
- Supervise geological technicians and other staff.
