Imagine this: If all the water in the world were somehow inside a water cooler, like the kind at your office, the amount of fresh, drinkable water would be one tablespoon.
And Americans are the world’s biggest water consumers, chugging, drinking, washing, flushing and irrigating without a second thought until most of us have used about 150 gallons a day each.
Compare that to the British who consume only 40 gallons a day, to the Chinese who average just 22 gallons a day, or to Kenyans, who scratch out a dry existence on less than 13 gallons a day.
In our soon-to-be-released Green Living Pulse study, we found that Americans’ engagement with water concerns actually fell a little bit from last year. About the same number of Americans say they’re concerned about the fresh water supply (69 percent), but fewer said they feel a sense of personal responsibility (64 percent, down from 75 percent).
This is serious point of concern. Water supplies are increasingly under pressure -- not only for drinking water, but also for generating power. We also use lots of water to power hydro-electric dams like Hoover Dam in Nevada. Lake Mead and Hoover Dam supply power to 2 million homes and businesses in Nevada, Arizona and California -- but Lake Mead is drying up. There’s a ring of mineral residue that’s 130 feet high all around the lake. Several scientists say there’s a good chance that Lake Mead will become a “mud pool” in the next dozen years or so if current trends continue.
Since 1998, the lake has lost more than half its water, more than 5.6 trillion gallons or enough to provide water for the entire country for about six months. The minimum water elevation needed to operate the generators is 1050 feet. As of last week, the water elevation level was 1088 feet, only 38 feet above the critical level.
Water conservation efforts aren’t making a big enough dent, perhaps because some cities in rain-scarce regions have some of the lowest residential water rates and the highest levels of water use. There’s no financial imperative. According to a recent study by Circle of Blue, a water news organization, a family of four using 400 gallons a day (100 gallons per person) will only pay $34.29 in Phoenix, but that number almost doubles to $65.47 in Boston. By the way, Boston gets about 10 times the amount of rain as Phoenix.
