Phase 1, 2, 3 and 4 Contaminated Land Reports

Phase 1 - The Phase 1 contaminated land survey is designed to give an overview of the risks of contamination to end users and the immediate environment. The report includes a walkover survey and a detailed study of the site history and current setting. The report should be submitted to the relevant Local Authority for assessment prior to any further investigations/analysis taking place on the property. Following submission, further reports/investigations may be required in order to safely develop the property.

Phase 2 - Further reporting on a site with potential problems should be in the form of a Phase 2 Site Investigation Report. Should this demonstrate that the site is not contaminated then no further works will be required. If the Phase 2 report demonstrates that the site is contaminated, further reporting and additional testing may be required by the Local Authority and possibly the Environment Agency, before the site development can progress.

Phase 3 - On completion of all  Phase 2 on-site testing works and in conjunction with confirmation of the final site layout, a Phase 3 Remediation Strategy Report should be completed to demonstrate how the site can be safely developed in respect of the end users. This will detail the methods to deal with each risk in respect of the property development.

Phase 4 - Following acceptance of the Phase 3 report by the appropriate authority, a Phase 4 Verification Report will then be required as the final report. This will be issued upon completion of the development works in order to prove that the Phase 3 recommendations have been carried out satisfactorily.

Soil & Water Analysis Reports
ASI offers comprehensive analysis and reporting for soil and water. This can be as part of a Phase 2 report or as specific testing from a single sample up to multiple samples for larger sites. Detailed reports are produced with site maps, interpretation and recommendations.

Mine Search Reports
ASI can arrange historic desktop mining reports for properties throughout the South West. Sometimes these are referred to as metalliferous reports or mine search reports. Mining reports are considered mandatory for mortgage and insurance purposes for property conveyancing in former mining districts.
