Summary of the investigation and clean-up:
  • During Phases 2 and 3 of the investigation, the Council determined that land at Denman Drive, Mayfield Close and Caroline Court is not contaminated land due to ground gases, groundwater pollution or sulphate attack on foundations.

  • This completed the investigation, by September 2009, for all but a handful of properties at the estate.

  • During the Phase 4 investigation, additional soil sampling was done at a small number of properties and two areas of open space. The conclusion of Phase 4 was that the land at these properties is not contaminated land, as defined by Part IIA of the Environmental Protection Act 1990.

  • Land at one area of public open space at the green in the centre of Denman Drive has been determined by the Council, on the basis of the work by our consultants, to be Contaminated Land in accordance with Part IIA of the Environmental Protection Act 1990. The land was contaminated by virtue of elevated levels of cyanide in shallow soils. These soils could have caused serious harm to young children if accidentally ingested. The contamination is from black ashy sand material deposited before the housing was built and the land was part of a landfill tip. The contaminated material is likely to have been waste from the manufacture of town gas at a gas works site.

  • The contaminated land was subject to clean-up in August 2011. Shallow soils were dug out and new clean soils placed over a special plastic layer. Unfortunately two trees had to be removed during the work, but these were replaced with young saplings. Turf has been laid and the site re-opened in early September 2011 once the turf had become established.
