As an environmental monitoring technician, your responsibilities are to collect samples from potential pollution sources and return them to a lab where you identify any environmental issues or violations. Your duties are to conduct investigations at job sites and manufacturing facilities, such as chemical or pharmaceutical production plants, where you perform surface testing on equipment, personnel, water sources, and processing areas. When you are not collecting samples in the field, you work in a lab setting, running pollutant identification tests on your samples and analyzing your findings to ensure that the company is following FDA and EPA regulations related to pollution control.
