Grading of beach water quality released
     The Environmental Protection Department (EPD) today (August 4) released the latest grading of water quality of 37 gazetted beaches and one non-gazetted beach (Discovery Bay) that are open for swimming.

     Eleven beaches were rated as good (grade 1), 22 as fair (grade 2), four as poor (grade 3) and one as very poor (grade 4).

Grade 1 beaches are:
Hap Mun Bay Beach South Bay Beach
Hung Shing Yeh Beach St Stephen's Beach
Kiu Tsui Beach Tong Fuk Beach
Lo So Shing Beach Trio Beach
Lower Cheung Sha Beach       Upper Cheung Sha Beach
Repulse Bay Beach  

Grade 2 beaches are:
Anglers' Beach Golden Beach
Butterfly Beach Hoi Mei Wan Beach
Cafeteria New Beach Kadoorie Beach
Cafeteria Old Beach Kwun Yam Beach
Casam Beach Lido Beach
Castle Peak Beach Ma Wan Tung Wan Beach
Cheung Chau Tung Wan Beach Middle Bay Beach
Chung Hom Kok Beach Pui O Beach
Clear Water Bay First Beach Shek O Beach
Clear Water Bay Second Beach Stanley Main Beach
Deep Water Bay Beach Turtle Cove Beach
Grade 3 beaches are:
Approach Beach       Silverstrand Beach
Big Wave Bay Beach Ting Kau Beach

Grade 4 beach is:
Discovery Bay  

     Compared with the grading released last week, Hung Shing Yeh Beach and Lower Cheung Sha Beach have been upgraded from grade 2 to grade 1; Butterfly Beach, Cafeteria Old Beach and Hoi Mei Wan Beach from grade 3 to grade 2. Chung Hom Kok Beach has been changed from grade 1 to grade 2; Silverstrand Beach from grade 2 to grade 3; Discovery Bay from grade 1 to grade 4.

     "The deterioration of water quality in Discovery Bay was due to heavy rain, while the changes in other beaches are generally within the normal range of fluctuation of the bacteriological water quality,” the EPD spokesman said.

     The EPD spokesman also said 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.

     Under the present grading system, beaches are classified into four grades according to the geometric mean of the E coli counts on the five most recent sampling occasions. Grade 4 is assigned to beaches whose E coli readings show abnormalities that may affect bathers' health. Bathers should avoid swimming at these beaches until their water quality improves.

     A summary of beach grades is published weekly before the weekend. Latest beach grades based on the most current data may be obtained from the department's websites on Beach Water Quality (www.beachwq.gov.hk or www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666.
