Environmental engineering technicians typically do the following:

• Set up, test, operate, and modify equipment used to prevent or clean up environmental pollution
• Maintain project records and computer program files
• Conduct pollution surveys, for which they collect and analyze samples such as air and ground water
• Perform indoor and outdoor work on environmental quality
• Work to mitigate sources of environmental pollution
• Review technical documents to ensure their completeness and conformance to requirements
• Review work plans to schedule activities
• Arrange for the disposal of lead, asbestos, and other hazardous materials

In laboratories, environmental engineering technicians record observations, test results, and document photographs. To keep laboratories supplied, they also may gather product information, identify vendors and suppliers, and order materials and equipment.

Environmental engineering technicians help environmental engineers develop devices used to clean up environmental pollution. They also inspect facilities for compliance with the regulations that govern substances such as asbestos, lead, and wastewater.
