What the experts are saying: Dr. Joseph Cotruvo
“Water has been reused continuously throughout history, by means of natural processes. Otherwise the earth would have run out of water thousands of years ago! Nowadays we have the technology to simulate natural processes, only more quickly. And we can produce water that usually is better than water from conventional sources. The poorer the water source, the better the technology needed to produce water that is suitable and safe for its intended use, whether that is cooling, irrigation, or drinking."
"Some people—including a few regulators—think we should use all available technology at any expense to produce the equivalent of high-end distilled water. That is costly and doesn’t benefit the public. The rational, sustainable approach is to (1) apply the appropriate technology to produce water that meets scientifically verifiable quality specifications, and (2) appropriately monitor the process and results. That way everyone can be confident that water supplies will always be available at an affordable price for our various needs.”
