水質監測 水質監測是確保食水安全的基本工具。我們實施全面的水質監 測計劃，對從水源* 到用戶水龍頭所收集的食水樣本進行一系 列的物理、化學、細菌、生物和輻射檢測，以監測整個供水系 統的水質。本年我們總共收集約17 萬個水質樣本並進行約60 萬個檢測，以確保食水水質完全符合香港食水標準。 * 水源包括東江水、本地集水區收集的雨水，以及將軍澳海水化淡廠引進的海水。 Water Quality Monitoring Water quality monitoring is a fundamental tool to drinking water safety. We undertake comprehensive programmes through a series of physical, chemical, bacteriological, biological and radiological examinations of samples collected from sources* to consumers’ taps to monitor water quality in the entire water supply system. During the year, some 600 000 tests were conducted involving about 170 000 water samples to ensure drinking water quality in full compliance with the HKDWS. * Water sources include Dongjiang water, rainwater collected from local water gathering grounds and seawater from the inlet of Tseung Kwan O Desalination Plant. 監測整個供水系統的水質 原水由木湖抽水站的東江水接收點、集水區與相關設施、水塘、 濾水廠、海水、海水化淡廠，途經配水庫、食水缸、分配系統 到達用戶水龍頭 （用戶包括商場、診所、社區設施、運動場、 街市、政府辦事處及屋邨管理處等）。 Monitoring Water Quality in the Entire Water Supply System From the reception point of Dongjiang water at the Muk Wu Raw Water Pumping Station, catchment areas and related facilities, impounding reservoirs, water treatment works, seawater, desalination plant, to service reservoirs, fresh water tanks, distribution systems and consumers’ taps (e.g. taps in shopping centres, clinics, community facilities, sports grounds, markets, government offices and estate management offices). 收集原水和食水樣本作全面測量 Collecting Raw and Drinking Water Samples for Comprehensive Examinations 使用氣相色譜串聯質譜聯用儀檢測水樣 本中有機化合物的痕迹。 Measure trace organic compounds in water samples using a gas chromatograph with tandem mass spectrometer. 使用微生物菌落計數器檢測水樣 本的細菌質量。 Examine the bacteriological quality of water samples through a microbial colony counter. 使用濁度計檢測水樣本 的混濁度。 Measure turbidity in water samples with a turbidimeter. 使用低本底阿爾法 - 貝他粒 子計數系統檢測水樣本的總 α 和總 β 活度。 Monitor gross alpha and gross beta activity in water samples with a low-level alpha-beta counting system. 使用電感耦合等離子體質譜儀 檢測水樣本中的微量金屬含量。 Measure trace metal contents in water samples using an inductively coupled plasma mass spectrometer. 測量食水樣本的餘氯 含量。 Examine residual chlorine levels in drinking water. 65 水務署 二零二三至二四年年報 WSD Annual Report 2023/24 Enhance 提升 Menu 目錄
