			This report describes the metadata generated during the creation of a 3D geological model for the Environment Agency (EA) in the Knowsley area in NW England. Knowsley Industrial Park, NW England and its buried sewerage network presents a potential source of pollution to the underlying Triassic Sherwood Sandstone Group aquifer. Weakly permeable superficial deposits beneath the site may provide a barrier to potential pollution of groundwater in the aquifer. The aim of the study was to develop and apply a 3D model of the superficial deposits beneath the park to a qualitative assessment of the vulnerability of the underlying aquifer to potential pollution. The study also aimed to devise a method for the integration of the 3D geological model of the shallow sub-surface with the buried utility network.

			The 3D model revealed 7 superficial units. Glacial till, comprising clay and silt, was the only weakly permeable deposit identified. Other deposits were interpreted as permeable. The underground utility network was integrated in 3D with the geological model. Those utilities overlying less than 2.5 m of till were interpreted to represent the most vulnerable parts of the underlying aquifer. The greatest relative vulnerability to the aquifer occurred in the south and south-west of the project area.
