Groundwater

There was an interesting post on BLDGBLOG yesterday that reminded me of one of the pages I added to the wiki on Thursday about the Great Miami Valley Buried Aquifer. The post refers to an article on New Scientist that's about the work UNESCO is doing related to groundwater resources. I figure it's a good excuse to do a post with a lot of maps in it...

These are the areas protected by various municipalites nearby:



Just for good measure, here are some more maps of groundwater resources for the whole state of Ohio:
