Odours
Odours are challenging to assess, due to difficulties in measuring them and their inherently subjective nature.
Air Quality Consultants has experience over many years in this field. We apply a range of approaches, including a desk-based odour risk assessment, sniff tests and dispersion modelling. The dispersion modelling is supported by at-source monitoring of odour emissions when appropriate.
Projects have covered:
-
sewage treatment works
-
composting facilities
-
intensive livestock farming (pig, poultry and dairy)
-
anaerobic digestion plant
-
waste transfer stations
-
slurry handling on farms
-
abattoirs
-
commercial kitchens and catering outlets
-
various industrial operations
-
contributions to planning appeals
Services
Modelling
Odour dispersion modelling using ADMS and AERMOD software for a range of odour sources based on at-source odour emissions measurements or published/library odour emissions data.
Monitoring
Odour monitoring in the field is conducted using sniff testing, which a large number of the members of the AQC team are trained to undertake. Sniff testing involves odour observations using the human nose, following published procedures and protocol to ensure consistency.
Assessment
Production of odour impact assessments for planning and Environmental Permitting, and Odour Management Plans.
Guidance
Contributed to IAQM guidance on the assessment of odour for planning (2018)
Expert Witness
Members of the team have provided expert witness evidence on odours at Public Inquiries.
