Geuroverlast

Geuroverlast is a Dutch term for odor nuisance, referring to unpleasant smells that interfere with the use and enjoyment of outdoor or indoor spaces. Odour nuisance is a form of environmental nuisance, often linked to human activities but can also arise from natural processes. The severity is somewhat subjective and depends on odor strength, duration, frequency, wind direction, and the sensitivity of nearby inhabitants.

Common sources include livestock operations (manure storage and spreading), wastewater treatment plants, composting facilities, landfills, food processing, and industrial plants that release volatile compounds. It can occur in rural or urban settings and may be exacerbated by temperature inversions or atmospheric conditions.

Assessment and regulation: Odor is typically measured in European odor units (ou_E) per cubic meter and determined via dynamic olfactometry (EN 13725). Many jurisdictions require odor assessments as part of environmental permitting; complaints to local authorities can trigger odor investigations, modelling, and potential permit adjustments. Regulations aim to minimize nuisance while balancing industrial and agricultural activities.

Mitigation: Odor control measures include process modifications, enclosure and leak prevention, air treatment such as biofilters, scrubbers, or activated carbon, wastewater covers, misting or mist suppression, and scheduling to reduce peak emissions. Buffer zones, vegetation, and community engagement also help.

Impact: Odor nuisance primarily affects comfort and quality of life, with potential indirect effects on sleep and property values; direct health effects are uncertain and mostly related to stress or exposure to irritants at high concentrations.
