Rearding Peter's note:
" There was similar legacy with deep lead/silver/zinc mining in the
Iglesiente district, in the south-west of Sardinia. The coastal limestone
aquifier was contaminated with sea water."
A number of boreholes and wells located fairly close to the coast which
extracted water for public supply from the East Durham aquifer suffered the
same fate and started to draw saline water As far as I am aware the sources
were abandoned in all cases. The reasons for the pollution were usually
said to be due to be 'over-pumping'.
