It’s World Water Day! Have you wondered where YOUR drinking water comes from?

The answer may be —from under your feet— if you live in Madison or one of the 30 other towns that drink water from wells drilled into the Buried Valley Aquifer. These wells produce high-quality inexpensive water from porous glacial sediments that were deposited in valleys that extend like tentacles across parts of Morris, Essex, Somerset, and Union Counties.

With all these towns pumping water out of this aquifer, why hasn’t it been used up?
