Nickel speciation in groundwater polluted with industrial wastes at Villa Farm, Warwickshire
In order to study the possible complexation of Ni, which as 63Ni is a significant radionuclide in the low-level radioactive waste inventory, the Villa Farm waste disposal site near Coventry has been examined. Nickel, together with a wide range of industrial organic compounds, has been deposited in a lagoon in hydraulic continuity with a shallow sand aquifer and the resulting pollution plume contains elevated Ni in association with dissolved organic carbon. Size exclusion and reversed phase HPLC techniques have been used to separate UV absorbing species present in groundwater samples. Ultra-filtration of Villa Farm groundwaters through membranes of various size also showed that the Ni was associated with relatively large molecular weight material.
