- Abstract:
- The aim is a conceptual model of water and potential contaminant fluxes from land surface to rivers via the Chalk aquifer, to underpin future basin management and risk analysis. First principles suggest that what protects Chalk rivers, springs and wells from contamination derived from the land surface is diffusion of solutes from fractures into the porous matrix. Using artificial and environmental (CFC) tracers to mimic contaminants, we shall find the proportions of flow in LOCAR catchments that have short residence times and little potential attenuation by diffusion while flowing through voids greater than about l mm wide, and what proportion passes slowly through smaller voids, with maximum attenuation and thus protection to resources and river ecology.
