	Significant fracture inflows occur at up to 100 m below ground level, and smaller inflows have been measured to at least 13 m depth.

	Groundwater flow paths are likely to be complex, due to the naturally layered nature of the aquifers, which tends to impart preferential horizontal flow, and the predominance of fracture flow. Groundwater may be present under unconfined or confined conditions, at various depths, and different groundwater heads are seen in different aquifer layers. Groundwater residence times are often in excess of 60 years (Ó Dochartaigh et al., 2011<ref name="Doch 2011">Ó Dochartaigh, B É, Smedley, P L, MacDonald, A M, Darling, W G, and Homoncik, S. 2011.

	Groundwater flow paths are likely to be even more complex than in Carboniferous aquifers not extensively mined for coal, due partly to preferential flow in the naturally layered aquifers, and partly to mining impacts. Groundwater may be present under unconfined or confined conditions, at various depths, and different groundwater heads are seen in different aquifer layers and/or mining levels. Groundwater residence times are often in excess of 60 years (Ó Dochartaigh et al., 2011<ref name="Doch 2011"></ref>).
