With a diminishing supply of safe freshwater in many areas, and increasing periods of drought that further limit that supply, we are facing a dilemma. According to the U.S. Department of Agriculture, farming uses consume nearly 80 percent of our available water. Now, producers and agricultural researchers are searching for alternative irrigation sources to limit this consumption and extend our water supply.
One solution is to irrigate crops using treated wastewater, otherwise known as reclaimed or recycled water. This recycled water, highly purified though perhaps not as pristine as drinking water, could be the key to a successful crop yield during times of drought when conventional freshwater is unavailable.
But, while recycled water is widely used in some countries — by 2012, 85% of the effluent in Israel was recycled — it has yet to be widely adopted in the U.S., due at least in part to concerns about consumer response. Read the full article on UDaily.
