问题       Remember the drinking f0untain,that once ubiquitous,and free,source of H2O? It seems quaint now. Instead, bottled water is everywhere. It’s refreshing, calorie-free, convenient to carry around, tastier than some tap water and a lot healthier than sugary sodas. But more and more, people are questioning whether the water, and the package it comes .in, is safe, or at least safer than tap water and if the convenience is worth the environmental impact.
     Evocative names and labels depicting pastoral scenes have convinced people that the liquid is the purest drink around. Yes,some bottled water comes from sparkling springs and other pristine (清新洁净) sources. But more than 25 percent of it comes from a municipal supply. The water is treated, purified and sold to us, often at a thousand-fold increase in price. Most people are surprised to learn that they’re drinking glorified tap water, but bottlers aren’t required to list the source on the label.
     The controversy isn’t simply about tap vs bottled water; most people drink both, knowing the importance of plenty of water. What they may not know is that some bottled water may not be as pure as they expect. In 1999 the Natural Resources Defense Council (NRDC) tested more than 1,000 bottles of 103 brands of water, which is the most recent major report on bottled water safety. While noting that most bottled water is safe, the organization found that at least one sample of a third of the brands contained bacterial or chemical contaminants, including carcinogens(致癌物质) ,in levels exceeding state or industry standards. Since the report, no major regulatory changes have been made and bottlers haven’t drastically altered their procedures, so the risk is likely still there.
     Besides, bottled water also affects the health of the planet. A big part of the appeal of bottled water is those convenient single-serving bottles. Yet fewer than 20 percent of them ever make it to a second life, according to estimates by the Container Recycling Institute. The rest are tossed onto beaches and roadsides and into landfills, where they could be around for a thousand years. Nestle Waters and other bottlers are trying to be greener, introducing lighter-weight bottles that use up to 30 percent less plastic. It’s a good start, but more needs to be done.
At least one sample of a third of bottled water brands tested by NRDC failed to meet
选项
答案state or industry standards
解析 原文第三段倒数第二句提到，NRDC进行的抽样检测显示，尽管多数品牌的瓶装水没有问题，但是三分之一的品牌送检的样品中至少有一瓶样品的细菌或化学污染物(包括治癌物质)超出国家或行业标准。题干中的 failed to meet意为“未能达到…标准”，是对原文in levels exceeding...standards的转述，故答案为state or industry standards。
