Monument record NDG 015 - Semer Borehole Pipeline, Anglian Water, Nedging-with-Naughton, (Prehistoric and Post Medieval)

2015: Strip, Map, Record and Evaluation revealed one small pit, a post medieval ditch and struck flint dating from the Mesolithic to the Iron Age periods, as well as small quantity of Neolithic pottery (S1).

Further trench evaluation of a strip of land south-east of the original pipeline location, prior to the construction of a Water Treatment Works. After the topsoil had been stripped, two trenches totalling 136m2 were excavated through the subsoil. In this area, the natural silty deposits containing worked flints were not present, however quarry pitting dating from the late Medieval to post-Medieval periods was uncovered and investigated. This activity is may relate to road and pathway/surface construction, the quarrying being for large gravel and cobblestone extraction. A walk-over survey of the subsoil was carried out to check for the presence of struck flints (as found further to the north during Phase 1), and none were found to be present within this area. However, a small number of residual flints were recovered from within the quarry pits (S2).
