The mighty Gulf of Mexico would have no problem assimilating any quantity of brine that we could possibly produce. The Gulf reaches a depth of 12,000 feet at its deepest point, and covers about 700,000 square miles. It has a salinity level of about 36 parts per 1,000 in open water. It holds 709,322,058,966,230,885 gallons of water. OK, I made that number up, but you get the point.
Desalination is the most environmentally-friendly solution to our water needs.
We take saltwater from the bay, and return it to the Gulf as salt and water in the exact same ratio. All we need to do is give the salt and the water a little time and space to remix. If done correctly, desalination will maintain a perfect natural balance and provide us with an inexhaustible supply of fresh water. This is a pretty unpopular view according to local talk radio callers, informal polls, and my water cooler discussions. Almost everyone thinks they did it.
