A magnetometry scanning survey was conducted on land at Springfield Park, Grantham in advance of a proposed expansion of Springfield Industrial Park. The aim of the survey was to determine whether detectable archaeological remains exist within the proposed expansion area and to determine their nature and extent. Scanning suggested the background levels of response over the majority of the site were quite high, and probably due to either demolition rubbish or magnetic material which had washed downslope and accumulated in a flat area. The southern, sloped area was magnetically quieter. The scanning survey was done in conjunction with a more detailed and refined magnetometry survey (ELI4346). {1}
