Two areas of interest are considered, that is the chalk blocks around Eastbourne/Beachy Head, and Folkestone/Dover, in order to assess the potential for using surplus winter chalk water to recharge deeper formations. The chalkitselfis not considered as a potential ASR formation. The two areas are geologicallyvery differentand are described separately; possibleaquifers are listed, and relevant features drawn together in Table I. The following descriptions focus on possible ASR formations, and do not describe the aquicludes between these. This study should be regarded as a first pass, with the information drawn mainlyfrom published maps and memoirs, with additionalboreholedata where readilyavailable. It should be noted that, particularlyfor the deeper formations, informationis very sparse. Where no data were available for these areas, information has been drawn from outside the area, and highlighted as such in Table 1. It should also be noted that transmissivity values defined for formations at outcrop or near surface, may not be applicable to the same formations when buried at depth This is likely to be a particular problem for limestones which rely on solution enlargement of fractures for much of their transmissivity development, although all formations will be affected dueto the pressure of overlying rocks.
