The first comprehensive study in the UK of
meiofauna within the HZ and their association
with the benthic community occurred during the
late 1980s (Rundle, 1990; Rundle and Hildrew,
1990). The growing international interest in surface
water-groundwater interactions coincided with
concerns regarding the physical and ecological
health of many groundwater-dominated rivers in
the UK. These concerns centred on lowland streams
dominated by groundwater (primarily chalk) and
the impact of a protracted drought (1990-1992)
and increased groundwater abstractions to meet
water supply needs on the salmonid fisheries and
wider riverine biodiversity (Castella et al. , 1995;
Marsh et al ., 2007). A range of inter-disciplinary
research projects centred on the HZ examined
surface water-groundwater hydrological exchange
and thermal characteristics of water within the
HZ (Evans et al ., 1995, Evans and Petts, 1997),
and the impact of sedimentation on fish spawning
and benthic macroinvertebrate habitat (Sear, 1993;
Acornley and Sear, 1999; Wood and Armitage,
1999).
The EC Water Framework Directive (Council
of the European Communities, 2000) and the
Groundwater Directive (Council of the European
Communities, 2006) specifically encouraged
regulatory authorities to consider groundwater
dependent ecosystems and groundwater ecology.
The Water Framework Directive (WFD) stimulated
a wider European interest in groundwater
ecology through the EU-funded Protocol for
the Assessment and Conservation of Aquatic Life
