BHA Consultings Commission

BHA were commissioned by Pigeon Investment Management Ltd & Landowners to prepare a Phase I Desk Study to assess the potential for contamination which might affect furfure residents and the environment.

A review of historical maps and local information identified that the site was developed in 1926 and formed the residential area of Felsted Sugar Beet Factory. Sugar production ceased in 1981 and on-site storage ceased in 1991, finally closing the factory. The wider area was remediated and decommissioned in 1999 to provide 50 acres of land for housing development.

The Conceptual Site Model and Qualitative Risk Assessment identified low risks to controlled waters based on the impermeable underlying Lowestoft Till and London Clay, which are both regarded as ‘non aquifers’ and the lack of surface water features associated with the site. Risks to future residents were also identified as low based on the known remediation of the wider area and lack of contaminative materials observed during the site walkover.

Therefore, a Phase II intrusive investigation was not considered necessary. However, due to the lack of topsoil, a 600mm layer of imported topsoil was recommended in garden areas to provide sufficient depth for regular gardening activities and as a suitable medium for plant growth.
