The geology, hydrogeology and geochemistry of the Needle`s Eye natural analogue site

Technical Report:

Abstract

The British Geological Survey has been carrying out a research investigation of the Needle`s Eye site at Southwick on the Solway coast in south-western Scotland. This study of a naturally radioactive geochemical system has the aim of improving our confidence in using predictive models of radionuclide migration in the geosphere. This summary report describes results from the integrated use of hydrogeological, mineralogical and geochemical techniques applied to the study of the transport and distribution of uranium. Pitchblende veins exposed in the cliffs are a major source of soluble uranium in ground-waters flowing into organic-rich post-glacial flood plain and intertidal mudflat deposits. Organic matter both living and dead has played a key role in the retardation of uranium in these sediments. Chemical transport modelling of the uranium dispersion/retardation is described and the implications for performance assessment work are discussed. Computer codes used: CHEMVAL (thermodynamic data base constants). CHIMERE (chemical equilibrium code). METIS (flow code). PHREEQE (chemical equilibrium code). STELE (coupled chemical transport code).
