Recharge plays an important role in the investigation of groundwater resources and knowledge of the spatial variability of recharge is important for the vulnerability of aquifers to pollution and management of diffuse pollution in groundwater. Many different techniques to estimate recharge exist, however recharge when drift is present is not well understood. The aim of this research is the estimation of local potential recharge through glacial till and alluvial deposits in the Upper Eden valley by means of different techniques including Chloride Mass Balance (CMB) in both unsaturated and saturated zones, nitrate in pore water, two applied tracer experiments and one dimensional unsaturated zone modelling. The experimental methodology consisted of field sampling and laboratory analysis to quantify the presence of tracers (i.e. chloride, nitrate and bromide) in the pore water extracted from drift cores.
