What are Senior Stack Testers?

Senior Stack Testers are experienced professionals responsible for conducting tests and inspections on emission sources, such as industrial stacks, to ensure compliance with environmental regulations. They use specialized equipment to collect and analyze samples of gases, particulates, and other pollutants released into the atmosphere. Senior Stack Testers typically lead testing teams, oversee safety protocols, interpret test results, and generate detailed reports for regulatory agencies. This role requires strong technical knowledge, attention to detail, and familiarity with environmental standards like the EPA’s Method 5.
