You need a bachelor's degree in a science-related field to become an environmental technician. Your responsibilities in this career require extensive knowledge of chemistry, biology, and water ecosystems. Anthropology, archaeology, and paleontology are also areas that prepare you for collecting samples, running tests, and reviewing the results. Your duties require you to do fieldwork and conduct laboratory testing, so you must be familiar with the equipment and have an understanding of the effects of waste on the health of the environment. Other qualifications include completed OSHA training, analytical skills, and certifications relevant to your area of study.
