     The Environmental Protection Department (EPD) today (September 15) released the latest grading of water quality for 39 gazetted beaches (see Note 1) and one non-gazetted beach (see Note 2).
     Twenty-one beaches were rated as Good (Grade 1), 17 as Fair (Grade 2), one as Poor (Grade 3) and one as Very Poor (Grade 4).

     Compared with the grading released last week, Clear Water Bay First Beach and Silverstrand Beach have been changed from Grade 1 to Grade 2, and Castle Peak Beach from Grade 3 to Grade 4.
     "The deterioration of water quality in Castle Peak Beach was due to the heavy rain throughout the week, while the changes in other beaches are generally within the normal range of fluctuation of the bacteriological water quality of the beaches," an EPD spokesman said.
     Under the present grading system, beaches are classified into four grades, namely Good (Grade 1), Fair (Grade 2), Poor (Grade 3) and Very Poor (Grade 4), according to the level of E. coli in the water. Grades are calculated on the basis of the geometric mean of the E. coli counts on the five most recent sampling occasions.
     While the ratings represent the general water quality at the beaches, the EPD spokesman reminded members of the public that water quality could be temporarily affected during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a tropical cyclone or heavy rainfall.
     A summary of beach grades is published weekly before the weekend. The latest beach grades based on the most current data may be obtained from the EPD's website on Beach Water Quality ( or the beach hotline, 2511 6666.
     In line with the vision to develop Hong Kong into a smart city, the EPD launched the Beach Water Quality Forecast System on August 15 to provide daily water quality forecasts for all gazetted beaches in Hong Kong that are open for swimming, to supplement the existing beach water quality monitoring programme and further enhance services to the public (see Note 3). From now on, members of the public can obtain the latest daily water quality forecast information for all beaches through the Beach Water Quality Forecast mobile application (available for download from: or the dedicated beach water quality forecast page ( on the EPD's beach thematic website.
