To ask Her Majesty's Government what assessment they have made of any risk posed by drilling near the contaminated land site at Newyears Green Bourne, including any associated risks such as the potential closure of the Blackford pumping station.

The site adjacent to Newyears Green Bourne (between Harvil Road and Harefield No.2 Lake) where High Speed 2 (HS2) is to be constructed is not designated as ‘Contaminated Land’ under the Environmental Protection Act 1991 (EPA). However, the Newyears Green Lane landfill site, located 400 metres to the North East of the site adjacent to Newyears Green Bourne is ‘Contaminated Land’.

HS2 have reviewed the potential for contamination to be present on the site adjacent to Newyears Green Bourne by referring to historic mapping, a site walkover and the sampling of groundwater. This investigation has not highlighted any previous activities likely to have caused contamination of the ground or the presence of any contamination attributable to activities on the site.

HS2 contractors are currently assessing risks associated with test piling at this site as part of an application for approval under Schedule 33 of the High Speed Rail (London – West Midlands) Act 2017. The Environment Agency will then review their risk assessment, which includes consideration of impacts on public water supply abstraction at Blackford pumping station.
