Abstract:		 The geomagnetic survey was carried out using a Bartington Grad 601-2 dual gradiometer system which utilises two sensors set 1m apart. The survey was undertaken within a system of 30m by 30m grids which were delineated across the site using temporary grid markers. The grids were set out and recorded using a Trimble R8 with an accuracy of up to 0.10m. The survey was undertaken using a zig-zag traverse pattern, utilising a sample interval of 0.25m and a traverse interval of 1m, providing 3600 sample measurements per full survey grid. Measurements were recorded on the Bartington’s on-board datalogger which was downloaded at regular intervals and backed up appropriately. Wardell Armstrong LLP (WA) was commissioned by Miller Homes to undertake a geophysical survey at Land to the south east of Rainford, St Helens, Merseyside centred at National Grid Reference (NGR): SD 48793 00161 The geophysical survey was required to inform a forthcoming planning application. The geophysical survey was undertaken in accordance with a Written Scheme of Investigation (WSI) produced in response to advice given by Alison Plummer, acting as the archaeological planning advisor on behalf of Merseyside Environmental Advisory Service. The objective of the geophysical survey was to determine the presence/absence, nature and extent of potential archaeological features within the study area, and the presence/absence of any known modern features within the survey area, which may affect the results. The survey was undertaken over five days between the 7thFebruary and the 11thFebruary 2022 and comprised of two fields of arable farmland. The investigation revealed several former field boundaries as illustrated on the Ordnance Survey 1st Edition map published in 1850. The survey results were quite ‘noisy’ suggesting that there has been spreads of demolition materials deposited and ploughed into the soil over the years, the likely source of this noise being the former cottages (HER MME7038), the former Rookery railway station (HER MME17445) and the possible coal mine (HER MME20595). Furthermore, a cluster of potential circular cut features were identified, possibly dating to the prehistoric period. The presence of further ephemeral features cannot be ruled out where masked from the geomagnetic noise.
