優化食水水質監測 多年來，我們實施一套食水水質監測計劃，於濾水廠、配水庫、 食水缸、供水接駁點和公眾可達的用戶水龍頭（例如商場、診 所、社區設施、運動場、街巿、政府辦事處及屋邨管理處等地 方的水龍頭）抽取食水樣本，以監測食水水質，並建立全港食 水水質數據庫以檢討香港食水標準。 自二零一七年，我們便推出「水質監測優化計劃」，藉此加強 水質監測範圍至用戶水龍頭，透過在全港隨機抽出處所，並在 其用戶水龍頭收集食水樣本，檢測可能在內部供水系統出現的 六種金屬，即銻、鎘、鉻、銅、鉛和鎳。我們亦由二零二一年 五月起，從上述的用戶水龍頭額外收集食水樣本化驗餘氯和埃 希氏大腸桿菌。有關這六種金屬、餘氯和埃希氏大腸桿菌的水 質統計數據， 每周於水務署網站上公布。 Enhancing Drinking Water Quality Monitoring Over the years, we have implemented a drinking water quality monitoring programme to collect drinking water samples from water treatment works, service reservoirs, fresh water tanks, connection points and publicly accessible consumers’ taps (such as those in shopping centres, clinics, community facilities, sports grounds, markets, government offices and estate management offices) to monitor the quality of drinking water and facilitate the creation of a territory-wide database for reviewing the HKDWS. Since 2017, we have launched the “Enhanced Water Quality Monitoring Programme” (Enhanced Programme) to strengthen our water quality monitoring at consumers’ taps in randomly selected premises in Hong Kong, and collect drinking water samples from these drinking taps for testing six metals, namely antimony, cadmium, chromium, copper, lead and nickel that could be present in internal plumbing systems. Starting from May 2021, we have collected additional drinking water samples from these drinking taps for testing residual chlorine and Escherichia coli (E.coli). The water quality statistics for the six metals, residual chlorine and E.coli will be published every week on the WSD website. 政府不時檢討香港食水標準，以確保食水水質和安全。最新香港食水標準於二零二一年四月發布，包含了 60個水質參數。此外，政府亦制定了監察名單、觀察名單，以及感官準則，以全面監察香港的食水水質。 The HKDWS is reviewed from time to time by the Government to ensure the quality and safety of our drinking water. The latest HKDWS were released in April 2021 with 60 parameters. In addition, the Government estblished the Surveillance list, the Watch List, as well as the Aesthetic Guidelines for comprehensive monitoring of the drinking water quality in Hong Kong. 點滴話你知 Did you know? 現新 Innovate 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 43
