Sampling & Testing Services

Comprehensive surface, wastewater, and indoor air quality testing for healthier, safer environments and compliance assurance.

Dunbar Services can perform surface swab plus airborne sample tests, checking for mould, fungi & bacteria,

  • Building surfaces
  • Air Conditioning systems
  • Occupied spaces
  • External locations

Dunbar’s calibrated air sampling unit draws a measured quantity of air across a sampling plate which is then analysed for microbial counts plus species identification. Testing is performed at the state’s leading NATA and AQIS certified, independent laboratory.

Dunbar provide a comprehensive report on the findings and recommendations for remediation if necessary.

Indoor Air Quality Assessment

Dunbar Services will attend the agreed locations to conduct an Indoor Air Quality Assessment and provide an in-depth report based on the parameters below. We interpret the results based on the information provided and industry standards to ascertain whether the Indoor Air Quality (IAQ) is suitable for occupancy at the time of testing as per AS/NZS 3666.2 and DA19 standards.

EVM7 used to conduct indoor air quality assessment The Airmet EVM7 is calibrated equipment designed to measure several different airborne containments or air pollutant applications including:

  • Particulates PM10
  • Total VOC
  • Carbon Monoxide
  • Carbon Dioxide
  • Temperature
  • Humidity

The EPA (Environmental Protection Agency) conducted a study over 25 years (1975- 2000) and determined that 107 measurable air pollutants, specifically carcinogens, exist in working environments. Combined with the advent of closed windows, modern office buildings and various cleaning solvents, the outcome has been energy efficient buildings and homes which contain levels of carcinogens. At high levels, this is known as “Sick Building Syndrome” and can cause acute effects such as headaches, eye/nose/throat irritation, dry cough or itchy skin, fatigue, and trouble concentrating just to name a few.

Area monitoring or spot checking for high levels of pollutants, such as particulates, VOC’s, and toxins, should be a common practice to ensure good indoor air quality exists in your environment. If poor air quality is determined, engineering controls such as proper air ventilation and the removal of toxic gases, would be put into place in order to provide an adequate working/living environment.
