Our contaminated land specialists can undertake site investigations to support planning applications, due diligence for land acquisition and to assess pollution risk(s) from accidental spills /loss of containment.
A site investigation is undertaken to provide a risk assessment of potential pollutant source-pathway-receptor relationships at a site. The information gathered is used to develop a Conceptual Site Model (CSM) which informs subsequent stages of investigation. If a site is indicated to be contaminated then we can design a remediation strategy and methodology to mitigate this risk.
Site investigations may include:
The data obtained from the site investigation is assessed to establish the level of risk to human health, property, protected species, soils, and /or the water environment based off site specific data.
We carry out site investigations which consider (but are not limited to) BS 10175:2011, BS 5930:2015, BS 8485:2015, BS 8576:2013, and CIRIA C665:2007.
We assess publicly available environmental, geological, historical, and hydrogeological databases to inform the environmental setting of a site and to identify the presence of potential pollutant-source-pathway relationships.
Our assessment also includes an on-site reconnaissance survey (or walkover survey) which considers the current site condition.
The information gathered is used to develop an initial Conceptual Site Model (CSM) which informs subsequent stages of investigation.
A Phase 2 site investigation may be required if potential risks to human health, property, protected species, or the environment is identified from the Generic Quantitative Risk Assessment (GQRA).
If the GQRA identifies significant risks then a further Detailed Quantitative Risk Assessment (DQRA) may be required.
The GQRA and DQRA uses site-specific information to estimate the level of risk from an identified active pollutant source-pathway-receptor relationship.
Once the pollution risk has been established we can design a suitable remediation strategy.
