'Fossil' groundwater's modern secret
The world's oldest and deepest waters are not immune from contamination, warn scientists.
It had been assumed that "fossil" reserves found hundreds of metres underground would be largely untouched by modern water sources.
But sampling from some 10,000 wells shows this not to be the case.
The new study reveals that about half of the deep groundwater has had contact with rains and snows that fell in the past 60 years.
And that means these ancient aquifers are also at some risk from pollution if waste and land management practices are defective.
It is an issue of significance because fossil waters are an important resource, providing drinking supplies and irrigation for billions of people across the globe.
this thread is partially related to the current discussions on this thread: World's Biggest Coal Company Closes 37 Mines as Solar Prices Plummet
Fracking isnt safe - Even isolated sites, impermeable layers waffle etc the water will eventually drain leech into aquifers etc earthquakes aside :)
