     The Environmental Protection Department (EPD) today (June 17) released the latest grading of water quality for 39 beaches.

Grade 4 beach is:

     The beach with an asterisk is a non-gazetted beach. All gazetted beaches are equipped with shark nets.

     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 department's websites on Beach Water Quality ( and or the beach hotline, 2511 6666.

     Compared with the grading released last week, Clear Water Bay Second Beach and Lower Cheung Sha Beach have been upgraded from Grade 2 to Grade 1, and Silver Mine Bay Beach from Grade 3 to Grade 2. Middle Bay Beach has been changed from Grade 1 to Grade 2, and Big Wave Bay Beach from Grade 2 to Grade 4.

     "The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches. The very poor water quality of Big Wave Bay Beach is largely due to the recent heavy rainfall," the EPD spokesman said.

     Under the present grading system, beaches are classified into four grades 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.

     Grade 4 is assigned to beaches whose last E coli reading exceeded a threshold figure, irrespective of the geometric mean. Swimmers are advised to avoid these beaches until the water quality improves.

     People are advised not to swim at the closed beaches.

     The EPD spokesman warned that many beaches were likely to be more polluted than their grades suggested during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a storm or heavy rainfall.
