A. D. Envirotech Microbiological Assessment Background
Microbiological contamination assessments are conducted to elicit whether or not mould or bacteria growth is present on a given surface or within a specified area. While mould and bacteria are a naturally occurring part of our environment, there can be marked impacts upon occupant health when present within a built environment. As such, caution should be taken whenever:
- Visible mould growth is present
- Odours are present
- Flooding or storm water overflow takes place
When any of these factors are detected, early action is required to ensure that rapid mould growth does not ensue, limiting the escalation of further damage both to the built environment and human health.
What is Microbiological hazard?
As a result of a mould or bacteria outbreak, a broad range of symptoms and health problems have been reported as being related to mould and bacterial exposure, including infections, fatigue, allergies, skin irritation and a range of toxic effects. Extra precautions should be adhered to if vulnerable people, such as young children, the elderly, the ill or those persons with chronic inflammatory disease (asthma or allergies) are potential exposed to such microbiological hazards. As well as these health hazards, additional problems associated with mould in the built environment include:
- Building material deterioration
- Structural deterioration
- Occupant dissatisfaction
The findings of the investigation will be compared against the threshold levels published in the:
- Guidelines for the investigation, assessment and remediation of mould in workplaces, March 2001 (Canada, Workplace Safety and Health Division Manitoba Department of Labour & Immigration)
- Guidelines for the NSW Site Auditor Scheme, NSW DEC, 2006
- Standards Australia. 1989. AS3666, air-handling and water systems of buildings, microbial control. Standards Australia. Sydney

ADE provides a team of qualified, experience and highly trained individuals that address the full spectrum of fungal, mould and microbiological problems using both air and swab sampling methods during inspections and clearance sampling programs.
The samples collected during the investigation works are collected, handled and delivered to our NATA accredited lab for analytical testing which is mediated by quality assurance and quality control (QA/QC) replicates.
The information collected during the investigation works is collated and a microbiological report is prepared detailing the results, outcomes and recommendations for remediation or management.
