Stack Emission Testing

Periodic Monitoring of air emission using DOE approved methods

What is Stack Emission Testing? 

Stack Emission Testing, also known as source emissions testing, involves measuring pollutant levels in waste gas streams released into the atmosphere. These waste gas streams can contain various pollutants such as liquid, gas, solid, organic, and inorganic compounds. Different pollutants require specific testing methods. Stack Emission Testing is mandated under the Environmental Quality (Clean Air) Regulations, 2014. Industrial premises are required to conduct stack emission testing to evaluate the characteristics and concentration of waste gas stream emissions.
