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. Investigations began in the mid
1970s when the mines were still active and continue now they have been
abandoned. As far as I'm aware there has been some limited success in
reducing the salinity with the prospect of extracting relatively 'fresh'
water from one mine.
