The Sieferts are the kind of environmentally conscious family who has solar panels atop their home. They use timers on their kids' showers and have planted drought-tolerant landscaping. But they feel kind of guilt. “I haven’t thought about the pool as much as I probably should,” said Annette Siefert.

As California's drought worsens, swimming pools have become a target for those who think the classic backyard greens waste water. Some water districts have banned new pools from being filled and have limited how much water existing pools can use.

But some of those agencies are walking back the rules as they make a surprising discovery: Pools aren't the water wasters some have made them out to be. Analyses by various water districts, along with scientific studies, conclude that pools and their surrounding landscapes use about the same amount of water as a lawn(草坪) of the same size. Over time, pools might even use less water. With pool covers, experts say water evaporation(蒸发)can be cut by almost half, making pools significantly less wasteful than grass and about as efficient as drought-tolerant landscaping.

Facing complaints over a recent ban on filling pools, the Santa Margarita Water District conducted its own water-use analysis. It found that pools require thousands of gallons of water to fill initially, but they use about 8,000 gallons less water than a traditional landscape after that. By the third year, the analysis found, the savings add up, and a pool's cumulative water use falls below that of a lawn.

Water agencies such as the Los Angeles Department of Water and Power have come to similar conclusions. Armed with new information, Santa Margarita Water District officials will reconsider their ban next week.

“We want to respect the people's rights to use their property. There are many families we know that have saved for pools,” said Jonathan Volzke, spokesman for the 155,000-customer district. “But at the same time, the reality around us is that we're in the third year of a serious drought, and we don't know if we're in the third year of a three-year drought or the third year of a 10-year drought.”

Americans get some of their news and entertainment from public television and radio. These public media receive money to operate from private citizens, organizations and government. Many of their programs are educational. But most of the American media are run by businesses for profit. These privately owned media have changed greatly in recent years. Newspapers, magazines and traditional broadcast television organizations have lost some of their popularity. At the same time, online, cable and satellite media have increased in numbers and strength. So have media that serve racial groups and those communicating in foreign languages.

In general, more media than ever now provide Americans with news and entertainment. At the same time, fewer owners control them. Huge companies have many holdings(股份). In some areas, one company controls much of the media. One dramatic change in American media is the increased success of cable television. It comes into most homes over wires. It does not use the public airwaves to present programs, as broadcast television does. Like broadcast television, most cable television programs perform advertisements. This is true although people must pay to see cable television in their homes. Thirty years ago, few people had cable. Today, about sixty-eight percent of American homes have cable television. Television by satellite also is gaining popularity.

Over the years, traditional broadcast organizations have tried to appeal to as many watchers as possible. Many cable companies, however, present programs for one special group of viewers. For example, there are cable stations for people who like books, cooking, travel, golf or comedy.
