sites on the Permo-Triassic Sandstone and Chalk aquifers to
assess the extent of chemical and microbiological contamination
emanating from unlined farm manure stores. Slurry along fracture
faces in the Chalk was found on cores taken from beneath two
stores. Porewaters from the Chalk sites and one of the Sandstone
sites were discoloured and showed high concentrations of
nitrate, ammonium and organic carbon to depths in excess of 10
m. Although Cryptosporidia and Escherichia coli O157 were found
in many of the cattle slurry lagoons, neit
