22 interesting facts about drinking water

A lot of water is wasted because so many people give little thought to where water comes from and where it goes after they use it.  Yet less than 1% of the Earth’s water is available for human consumption.  And there is no “new” water on Earth.

Excess Logic continues reposting interesting articles about hi-tech, startups and new technologies to draw attention to e-waste recycling of used computer, lab, test, data center, R&D, computer and electronic equipment. Please stop disposing of used equipment into a dumpster. Recycle used electronics with Excess Logic for free.

The water we use comes from surface water (reservoirs, lakes,etc.) or ground water (aquifers).  In drier areas water is pumped from deep aquifers, underground reservoirs formed over many centuries by water trickling down until it meets solid rock.  This water is now pumped out far faster than it can be replenished, causing the ground to contract and sink. This is called subsidence.  Along with water shortage problems, many cities worldwide are being faced with subsidence problems.
