Land Contamination Surveys

Have you been asked for a Land Contamination Survey or Desktop Study but are not sure what is involved? Castledine Environmental are a well-established, nationwide and experienced company specialising in producing Land Contamination Reports to support planning applications or to satisfy Planning Conditions. We work throughout the country and our reports are written to comply with both Local Authority Standards and Industry best practice.

When planning permission is sought on a brownfield site, it is likely that the planners will ask for a Phase 1 Desk Top Study (also known as a Desk Study, Desktop Survey, Preliminary Site Investigation, Stage 1 Survey). This report collates information on contaminant sources, potential receptors, and pathways between them which shows whether the land is likely to pose a significant risk to human health or the wider environment.

Sometimes this will show that harmful contamination is unlikely, and that no further action is required however if the Phase 1 Study shows that there is a credible risk of potential contamination, then a Phase 2 Intrusive Investigation will be required to further assess the risk. This can involve sampling soils and water, laboratory analysis and sometimes monitoring of gas.

If contaminants are identified, a Phase 3 Remediation Strategy will be required, which outlines the options for preventing the contaminants impacting receptors. On completion of the remediaton a Phase 4 Validation Report will be required to demonstrate that the remediation has been done to an acceptable standard.
