Stack Testing

Exposure Science Consulting offers a range of point source and stack emissions monitoring in line with US EPA methodology. We help industries and organisations measure and manage the particulates, gases and pollutants they release into the environment because of their processes. We call this “stack emissions,” which refers to the gases that are released from chimneys, exhausts, or other sources.

Our main goal is to make sure that these emissions are within the limits set by environmental regulations. We do this by conducting tests and measurements to accurately determine the types and amounts of pollutants being released which is often required for resource consent purposes. One of the techniques we use is called “isokinetic sampling,” which involves taking representative samples of the contaminants being emitted.

Our environmental team is accredited to assist with discharge to air resource consent monitoring requirements. Utilising the latest isokinetic and real-time detection technology, our team can assist with the following methods:

• Filterable Particulate Monitoring – USEPA Method 5, Method 17, or ISO 9096:2017

• Carbon Monoxide – USEPA Method 10

• Hydrogen Sulfide – USEPA Method 14

• Sulphur Dioxide – USEPA Method 6C

• Nitric Oxide – USEPA Method 7E

• Nitrogen Dioxide – USEPA Method 7E

• Hydrogen Halides – USEPA Method 26A

• Metals – USEPA Method 29

• PM2.5 & PM10 – USEPA Method 201A

• Condensable Particulate – USEPA Method 202

• VOCs – various methods

• Formaldehyde - Method CI/WP-98.01

• PFAS - SW-846 Test Method 0010

• Specialty methods as required
