1 Introduction Groundwater and surface water levels have been recorded across the Blick Mead site, as part of the Applicant's commitment to ongoing monitoring at this location (as noted at paragraph 11.3.14 of the ES). This data is not required to inform the EIA. Levels have been recorded both manually using a dip meter or gauge board and automatically using a data logger. A map of the site showing the locations of each monitoring point is given in Appendix A. A summary of manual dips collected thus far are given in the below tables. A series of graphs displaying the automatic logger data gathered to date are given in Appendix B, the manual dips are also displayed on these graphs to confirm the accuracy of the data loggers.

11 Summary This report provides the results of on-going groundwater recording and monitoring at Blick Mead, as requested by stakeholders, and reports results which are consistent with the findings of the Tiered Assessment presented in Annex 3 of Appendix 11.4 - Groundwater Risk Assessment [APP-282] and the ES.
It is noted that, while stakeholders with an interest in Blick Mead have requested that additional piezometers are installed in the same general area at more dense spacing, this is still under discussion.
