Odour Assessments: How to Identify, Understand and Manage Odour Issues
Odour can quickly become a significant issue for businesses operating near homes, workplaces, or other sensitive environments. What begins as an occasional smell can lead to repeated complaints, compliance concerns, and strained relationships with surrounding communities.
Professional odour testing and assessment provides businesses with objective information to better understand where an odour is coming from, how significant it is, and what action may be needed.
At Verum Group, we provide professional odour assessments across New Zealand, the Pacific and Asia, helping organisations investigate odour concerns and manage them more effectively.
When Is an Odour Assessment Needed?
Odour issues can arise from many different industries and activities, including:
Wastewater treatment
Landfills and waste facilities
Composting operations
Agriculture
Food processing
Manufacturing and industrial processes
An odour assessment may be useful when complaints are being received, operations are changing, a new development is being planned, or a business needs to better understand the impact of odour beyond its site boundary.
The earlier an issue is investigated, the easier it can be to understand its source and determine appropriate management measures.
What Is a FIDOL Assessment?
One method used to assess odour impacts is the FIDOL approach.
FIDOL considers five key factors:
Frequency – How often does the odour occur?
Intensity – How strong is it?
Duration – How long does it last?
Offensiveness – How unpleasant is the odour?
Location – Where is the odour occurring and who may be affected?
Considering these factors together provides a more complete picture than simply determining whether an odour is present.
Finding the Source of an Odour
Knowing that an odour exists is only part of the investigation. Understanding where it is coming from is critical to managing it effectively.
Verum Group’s experienced odour scouts can undertake structured field observations, recording factors such as odour intensity, location, and wind direction.
This information can help trace an odour back to its likely source and identify which activities or processes may be contributing to the problem.
Turning Odour Assessments Into Action
Once an odour issue is better understood, businesses can make more informed decisions about how it should be managed.
An assessment may help organisations:
Investigate community complaints.
Identify likely odour sources.
Understand when and where impacts occur.
Review the effectiveness of existing controls.
Support resource consent or environmental requirements.
Develop practical odour management measures.
Objective information also gives businesses a stronger basis for communicating with regulators and surrounding communities.
Professional Odour Assessments
Odour issues can be complex because they are influenced by the source, weather conditions, site operations, and the surrounding environment.
Verum Group provides professional odour assessment services across New Zealand, the Pacific and Asia, helping businesses move from complaints and uncertainty to clear evidence and practical next steps.
