Grading of beach water quality released

     The Environmental Protection Department (EPD) today (September 8) released the latest grading of water quality for 37 gazetted beaches and one non-gazetted beach (Discovery Bay) that are open for swimming.

     Twenty-two beaches were rated as Good (Grade 1) and 16 as Fair (Grade 2).

Grade 1 beaches are:
Cheung Chau Tung Wan Beach Lower Cheung Sha Beach
Chung Hom Kok Beach Middle Bay Beach
Clear Water Bay First Beach Repulse Bay Beach
Clear Water Bay Second Beach Shek O Beach
Deep Water Bay Beach South Bay Beach
Discovery Bay St Stephen's Beach

Approach Beach Hoi Mei Wan Beach
Big Wave Bay Beach Kadoorie Beach
Butterfly Beach Lido Beach
Cafeteria New Beach Ma Wan Tung Wan Beach
Cafeteria Old Beach Pui O Beach
Casam Beach Silverstrand Beach
Castle Peak Beach Ting Kau Beach

     Compared with the grading released last week, Clear Water Bay First Beach and Discovery Bay have been upgraded from Grade 2 to Grade 1. Cafeteria New Beach, Golden Beach and Ma Wan Tung Wan Beach have been changed from Grade 1 to Grade 2. 

     "The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches," 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.

     The EPD spokesman also warned that many beaches were likely to be temporarily affected during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a storm 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 department's websites on Beach Water Quality ( and or the beach hotline, 2511 6666.
