Shieldaig : borehole drilling and testing

Abstract

Three trial boreholes for potential public water supply were drilled near Shieldaig, in September- October 2004. The target aquifer was Torridonian sandstone. The boreholes were commissioned by Scottish Water. The project was managed by Galliford Morgan Joint Venture. Advice on borehole siting, construction and testing was provided by the British Geological Survey (BGS). The boreholes were drilled and pumping tests carried out by Drilcorp. This report presents geological and hydrogeological data collected during borehole drilling and testing and assesses the hydrogeological characteristics of the borehole and its suitability to provide a public water supply
