Odour Monitoring

Overview

Odour is the environmental issue that generates the most community complaints—and the hardest to address with data alone. What's objectionable is inherently subjective. What constitutes a problem depends on who's experiencing it, when, and for how long. Assured Environmental brings rigour to odour monitoring across Australia. From field olfactometry that quantifies what instruments can't detect, to systematic observation programs that document character and extent, to community surveys that capture real-world experience—evidence that transforms subjective complaints into objective understanding.

Key Capabilities

• Field Olfactometry – Quantifying odour concentration in the field using calibrated dilution olfactometers. Objective measurement at the point of impact—data that establishes whether odour is present, at what intensity, and from which direction.
• Odour Observations – Systematic recording of odour character, intensity, duration, and extent by trained assessors. Capturing the qualitative dimensions that support impact assessment and source identification.
• Community Odour Surveys – Structured surveys that document how communities actually experience odour over time. Panel surveys, diary studies, and complaint analysis that track impact patterns and measure mitigation effectiveness.
• Source Identification Surveys – Tracing odour back to its origin through systematic field investigation. Walking the plume, characterising sources, and building the evidence that connects impact to cause.
• Odour Event Monitoring – Rapid-response monitoring when complaints occur or conditions suggest impact. Capturing evidence during events—not after they've passed.
• Baseline Odour Assessment – Documenting pre-existing odour conditions before new developments or changes. Establishing what communities already experience, so future impacts can be assessed in context.
