A geophysical survey was carried out by Archaeological Surveys Ltd along the route of a new water pipeline between Lark Hill reservoir and Childrey Warren Water Treatment Works to the south of Wantage in Oxfordshire. The results of the survey indicate widespread magnetic contamination introduced during soil conditioning/manuring within the majority of the survey areas, which could have obscured weaker features if present. However, several areas of archaeological potential have been located which include a positive linear anomaly associated with a former boundary within Area 6, negative linear anomalies and magnetic debris associated with possible 19th century or earlier structural remains in Area 9 and a number of ditches, enclosures and pits within Area 10. Further enclosures, linear ditches, pits and a possible ring ditch have also been located at the western end of the survey corridor within Area 13. LiDAR data analysis reveals a landscape containing a series of long, linear boundary banks forming a widespread field system, with several of these banks existing within many of the survey areas. They do not, however, have a corresponding magnetic response.
