Phase 1 Contamination Assessments

Phase 1 Contamination Assessments comprise a desk study and walkover survey. These are core services provided by Ruddlesden geotechnical and form the fundamental and underpinning part of all contamination assessments.

Based on a combination of the desk study, including historical, environmental and geological information, and walkover survey information, a conceptual site model (CSM) is produced, identifying the likely contamination source-pathway-receptor linkages.

Depending on the findings of the preliminary/ Phase 1 contamination risk assessment, no further action or remedial measures might be necessary, or a Phase 2 (intrusive) investigation might be recommended to identify which of the contamination source source-pathway-receptor linkages exist and whether any remedial measures are required.

Case Study

Pre-Purchase Phase 1 Contamination Assessment

Phase 1 Contaminated Land Assessment for the proposed redevelopment of a brownfield site in Devon, as part of the pre-purchase appraisal for the construction of a new supermarket.

The site had numerous historical industrial land uses, including an iron foundry, gas works and an engineering works, as well as documented evidence of historical contamination of the ground, associated with an adjacent gas works.

The production of the Phase 1 was crucial to understanding the potential development (and cost) constraints at this site for the client, prior to purchasing, and formed the basis of the scope of works for the Phase 2 Contamination Investigation.
