Agar plates - laboratory assessment for microorganismsteria

Mould & Bacteria

Mould and bacteria occur naturally in our environment, and are responsible for a wide range of naturally occurring processes. However, property owners, building managers and/or occupants should act when one or more of the following occurs:

  • Visible mould growth is observed
  • Odours are present
  • Flooding or water ingress takes place

Following an event that causes water damage, high moisture levels can lead to mould growth on building materials and building contents.  Mould levels can rapidly escalate and this can have a severe impact on occupant health.  It is important that as soon as mould is suspected, an investigation is conducted to determine the extent of damage, the potential cause, the risk associated to occupants and or visitors, and the potential for remediation. Detailed scientific risk assessment can prevent expensive demolition and delay to re-occupation.

Mould within the built environment, can be responsible for:

  • Adverse impacts on occupant health and wellbeing, particularly for sensitive individuals
  • Building material deterioration
  • Structural deterioration
  • Occupant dissatisfaction
  • Occupant outrage
  • Reduced productivity

CETEC has a wide range of highly skilled scientists and engineers to assist with mould and bacteria issues. CETEC will first attempt to establish the source of the mould or bacterial growth and then adopt a disciplined sampling methodology.  This may include airborne sampling and swabbing of representative affected areas. In many instances, speciation may be necessary as some species are more hazardous to human health than others. Importantly, action is required in a timely manner, as water damage can result in rapid mould growth and escalate to further ongoing damage and impacts on human health.

Following appropriate testing and analysis for mould species and bacterial growth, CETEC can provide recommendations and devise a remediation plan, including project management, if required.  The team at CETEC has risk assessed, analysed and remediated a number of complex mould investigation projects throughout Australia. We work with our clients to meet both their immediate risk requirements and achieve long term project outcomes.
