Environmental Scientist

Environmental science concerns itself with the impact of human activity on the environment and deals with subjects such as chemistry and biology, both in the field and in the lab.

They gather up samples and observational data in the field and conduct tests in the lab. For example, they often analyse water and soil for pollutants caused by industry and agriculture. They will test water, soil or air samples to find the type, concentration and source of the pollution. The environmental scientist will then undertake a rigorous assessment to identify if that contaminant source has the potential to affect or harm individuals and communities.

  • Water Quality Scientist

What the job involves 

  • Conduct field surveys: collecting data to establish a baseline condition for levels of pollution or contamination for a site or area of consideration
  • Conduct lab tests on water, air and soil
  • Interpreting data to identify whether contamination exists in accordance with environmental laws
  • Build conceptual models that identify the potential contaminant sources that could potentially have an adverse impact on the environment
  • Write detailed scientific reports
  • Communicate the results

How your career can develop

A career as an environmental scientist offers the opportunity for a structured professional path with the potential to specialise in an area of interest such as lab manager, project manager, field scientist, environmental consultant or environmental engineer.

Why it matters?

The world is becoming more crowded, more consuming, and more connected. Growing populations and higher standards of living have placed increasing pressure on the environment. Growing environmental problems like water scarcity and fossil fuel consumption are in dire need of intelligent solutions.  Environmental scientists have a huge role to play in ensuring a sustainable environment.
