Abstract. This work has arisen out of recent developments within the radioactive waste research programme managed by Her Majesty's Inspectorate of Pollution, UK (HMIP)*, to develop an integrated flow and transport model for the potential deep radioactive waste repository at Sellafield. One of the largest sources of uncertainty in model predictions, is the characterisation of the hydrogeological properties of the underlying strata, in particular, of the Borrowdale Volcanic Group (BVG) within which the repository is to be located. Analysis of the available borehole data (that released by the proponent company, Nirex, by December 1995) for the BVG formation has indicated a dual regime consisting of flow within faults and flow within the matrix (or an equivalent porous medium containing micro-fractures). Significant relationships between permeability, depth and the presence and orientation of faults have been identified; they account for a variation of up to 6 orders of magnitude in mean permeability measurements. This can be explained in part by the effect of the orientation of the current maximum principal stress directions within the BVG: however, it is likely that permeability is also dependent on the existence of fracture families, which cannot be effectively identified from the data currently available. These analyses have enabled considerable insight to be gained into the dominant features of flow within the BVG. The conceptual hydrogeological model derived here will have a significant effect on the outcome and reliability of future radionuclide transport predictions in the Sellafield area.

Set Up

Growing urban areas in the Latium volcanic domain has resulted in the increase of water demand. The uncontrolled increase in water withdrawals cause an inexorable reduction of springs discharges and progressive drawdown of groundwater levels. This emergency needs an urgent rationalization of groundwater management thorough understanding of qualitative and quantitative features of the aquifers. The main aim of this paper is to emphasize the importance of the method of study and the results obtained by researchers belonging to the Laboratory of Quantitative Hydrogeology (University of Roma Tre) to support the use and protection of groundwater resources. Therefore, we propose a summary of methods applied in previous hydrogeology studies that have contributed to legislation on groundwater resources management in the volcanic aquifers. The study area corresponds to the Latium volcanic domain and covers approximately 6500 km2. About 3000 stratigraphic data and about 2600 water points have been collected in order to set up a conceptual hydrogeological model. The conceptual model has been validated by the resolution of the hydrological budget. Detailed evaluation of the water supply is essential for the correct setting of the hydrological budget, in fact it represents the main output of the budget. These analysis highlight the condition of the resource. Critical areas have been identified for reshaping of water supply in order to increase environmental remediation and economic development.
