How do you find water underground?
We asked our guest Richard Davies
All rocks, all sedimentary rocks contain water. What we’re really looking for is rocks that have porosity and permeability. So you can look at outcrops to find out which are the right suitable rock types and you can drill holes and hopefully intersect those rock types. All sediments contain water and it’s actually when they’re buried that you’re actually squeezing the water out very slowly. It’s really a matter of looking for the suitable rock types. For example, chalk beneath London is a suitable aquifer. It has been historically, anyway.
yeldas asked the Naked Scientists: hi This is Yeldas. I am very much interested in how you find underground water? What do you think? yeldas, Thu, 8th May 2008
Actually, for a hard rocker, ( it is my taste in music, not geology) you did quite well. I see nothing that needs to be added.
More like tracing indicator elements in groundwater to try to find deposits. Bass, Fri, 9th May 2008
OK, much more sophisticated stuff than I realized. Bravo - you know what a sand is !!! JimBob, Sat, 10th May 2008
