bạn có uống nước vệ sinh không? California chấp thuận nước thải có thể cho người uống...
-----
When a toilet is flushed (phun ra) in California, the water can end up in a lot of places: an ice-skating rink (sân trượt băng) in Ontario, ski slopes (dốc trượt tuyết) around Lake Tahoe, farmland (đất nông nghiệp) in the central valley.
And – coming soon – kitchen faucets (vòi bếp).
California regulators (cơ quan quản lý) on Tuesday approved rules to let water agencies (cơ quan) recycle wastewater (nước thải) and put it into the pipes (đường ống) that carry drinking water to homes, schools and businesses.
It’s a big step for a state that has struggled for decades (thập kỷ) to secure reliable sources (nguồn đáng tin cậy) of drinking water for its more than 39 million residents (cư dân), and it signals a shift (báo hiệu một sự thay đổi) in public opinion on a subject that as recently as two decades ago prompted backlash (gây ra phản ứng dữ dội) that scuttled (làm đắm chìm) similar projects.
Since then, California has been through multiple extreme droughts (hạn hán), including the most recent one, which scientists say was the driest (khô nhất) three-year period on record and left the state’s reservoirs (hồ chứa của bang) at dangerously low levels.
“Water is so precious (quý giá) in California. It is important that we use it more than once,” said Jennifer West, the managing director of WateReuse California, a group advocating (ủng hộ) for recycled water.
California has been using recycled wastewater for decades. The Ontario Reign minor league (giải đấu nhỏ) hockey team has used it to make ice for its rink in southern California. Soda Springs ski resort near Lake Tahoe has used it to make snow. And farmers in the central valley, where much of the nation’s vegetables (rau củ), fruits (trái cây) and nuts (quả hạch) are grown, use it to water their crops (cây trồng).
