The aim of the approach is to have a common framework that can scale to any number of activities that might take place prior, pre, during or post development. The key aims are to have a stepwise approach to enable effective screening of potential areas of concern; encourage appropriate and sufficient data collection and site investigation to support robust decision making; facilitate timely identification and understanding of risky activities and identify the point where mitigation and further Quantitative Risk Assessment is necessary to protect vulnerable on and off site receptors.

This protocol provides a draft outline of a potential activity-based sampling approach for the testing of asbestos fibre release potential from residential garden soil as part of a staged investigation strategy for land being investigated under Part 2A of the Environmental Protection Act 1990. The primary objective of the Activity-Based Sampling (ABS) protocol is to provide a reasonable worst-case estimate of current and future fibre-release and subsequent localised airborne fibre concentrations that might be possible as a result of soil disturbance.

This protocol provides a draft outline of a potential sampling approach developed by the SoBRA Asbestos-in-soil sub-group. It aims to strike a balance between traditional soil survey sampling strategies and soil sampling strategies designed specifically for known asbestos containing soil, made ground and aggregate.
