To ensure the land is suitable for building homes on we have carried out extensive intrusive ground investigation works across the whole site in consultation with Environmental Health Officers at South Northamptonshire Council and Northampton Borough Council. These works have helped us determine the extent of any contamination and the required remediation works needed before we start construction.
The findings from this work identified areas of landfill across the southern part of site and some associated small pockets of contamination, known as ‘hotspots’. With the exception of these hotspots, the remainder of the site registered normal readings for residential land use.
None of the contaminants recorded as hotspots exceed the relevant thresholds for residential land and would not pose a risk to future residents of our proposed development. However, we have developed a remediation strategy as part of our application which sets out how we will clear away these areas of contamination ahead of any homes being built. The likely strategy will involve removal of material to suitable landfill sites or capping with clean soil.
