The site is situated immediately north of the Springwood Farm access road, to the north-east of Thorney. Archaeological monitoring was undertaken during the excavation of 3 trial pits within the site in April 2010, and during the subsequent groundworks carried out in March 2011. Each trial pit was machine excavated to a depth no greater then 3.5m in order to ascertain ground conditions. The main groundworks comprised the topsoil stripping of a 400m2 area to a depth of 0.5-0.8m, and the further excavation of a 44m2area to a depth of 1m for the new sewage treatment tank. Archaeological monitoring during the groundworks did not identify any evidence of human activity prior to the modern period. The entirety of material found is likely attributed to construction activity associated with the creation of the present sewage treatment works, and ground improvement activity adjacent to the road.
