The investigation of contaminated land issues can be sub-divided into four phases:
- Phase I – Desktop Study & Walkover Survey – A review of historical information and other environmental searches, to establish the potential risk of contamination associated with previous or neighbouring land uses.
- Phase II – Intrusive Site Investigation – Soil / groundwater testing to better characterise the on-site ground conditions and establish the level of any risk to future site users.
- Phase III – Options Appraisal & Remediation Strategy – The choice of remediation approach / methodology to clean up the site or otherwise protect potential ‘Receptors’ from hazardous ground conditions.
- Phase IV – Verification / Validation – The process of documenting the remedial works and certifying the final condition of the site.
The Government is committed to bringing more Brownfield-land back into sustainable use. Concentrating development on Brownfield-sites can help to make the best use of existing services such as transport and waste management. It can encourage more sustainable lifestyles by providing an opportunity to recycle land, clean up contaminated sites and assist environmental, social and economic regeneration. It also reduces pressure to build on Greenfield-land and thereby protecting the countryside.
Land contamination poses a number of potential ‘risks’ to the UK Developer. It is therefore essential to identify and quantify these risks at the earliest stage. A comprehensive and detailed site assessment provides the client with a basis on which to forecast costs.
