據(jù)外媒報(bào)道,，加拿大政府一項(xiàng)最新調(diào)查顯示,，目前有數(shù)百萬(wàn)加拿大人仍在飲用不衛(wèi)生的自來(lái)水,。加拿大每年有30多萬(wàn)人因飲用市政供應(yīng)的自來(lái)水而感染急性腸胃炎,，有些人甚至需住院治療,。

       據(jù)報(bào)道,，安大略省Walkerton小鎮(zhèn)在2000年發(fā)生大腸桿菌污染飲用水事件,，造成7人死亡和2,300人患病,，政府曾多次發(fā)布警告,，但數(shù)以百萬(wàn)計(jì)的加拿大人仍飲用市政及私人系統(tǒng)提供的不達(dá)標(biāo)生活用水,。

       加拿大公共衛(wèi)生署（PHAC）及加拿大衛(wèi)生部（HC）的調(diào)查人員認(rèn)為，整體上看加拿大人因飲用水患病的風(fēng)險(xiǎn)仍然很低,。

       但他們建議,，更多的城市要考慮實(shí)施多重自動(dòng)防護(hù)屏障水處理程序，這是經(jīng)過(guò)證明保證水質(zhì)的有效方法,。實(shí)際上多數(shù)加拿大人用的自來(lái)水就是這種水源,。

       調(diào)查人員稱，有近150萬(wàn)加拿大人仍然飲用市政系統(tǒng)提供的只經(jīng)單一水處理程序或未經(jīng)處理過(guò)的飲用水,，而且是易受污染的地表水,。

       部分原文報(bào)道如下：

       More than 300,000 Canadians contract an acute stomach bug every year from the municipally-supplied water that comes out of their taps, some likely ending up in hospital or even dying, a new government study suggests.

       The research also concludes millions of people are still getting their drinking water from substandard municipal and private systems - despite repeated safety warnings after the tainted-water disaster in Walkerton, Ont.

       The authors at Public Health Agency of Canada and Health Canada argue the overall figures show the risk of getting sick from drinking water in Canada remains low.
