In addition, more localised Principal aquifers including the Corallian and Carboniferous Limestones were sampled. Additional samples were collected from Secondary aquifers; West Walton Formation, Coal Measures and the Millstone Grit Group (Table 5). The geology of the region and the location of these samples are shown in Figure 9. The Namurian Bowland Shale Group is also the target formation for unconventional gas exploration in this area (Andrews, 2013&amp;lt;ref name=&quot;Andrews 2013&quot;&amp;gt;&lt;del style=&quot;font-weight: bold; text-decoration: none;&quot;&gt;ANDREWS, I J. 2013.
