Grading of beach water quality released
     The Environmental Protection Department (EPD) today (June 14) released the latest grading of water quality for 38 gazetted beaches that are open for swimming and one non-gazetted beach (i.e. Discovery Bay*).

     Fourteen beaches were rated as Good (Grade 1), 15 as Fair (Grade 2), nine as Poor (Grade 3) and one as Very Poor (Grade 4).
Grade 1 beaches are: 
Cheung Chau Tung Wan Beach Repulse Bay Beach
Chung Hom Kok Beach South Bay Beach
Discovery Bay St Stephen's Beach
Hap Mun Bay Beach Stanley Main Beach
Hung Shing Yeh Beach Tong Fuk Beach
Kiu Tsui Beach Trio Beach
Lo So Shing Beach Upper Cheung Sha Beach
Grade 2 beaches are:
Cafeteria New Beach Lower Cheung Sha Beach
Cafeteria Old Beach Middle Bay Beach
Castle Peak Beach Pui O Beach
Clear Water Bay First Beach Shek O Beach
Clear Water Bay Second Beach Silver Mine Bay Beach
Golden Beach Silverstrand Beach
Kadoorie Beach Turtle Cove Beach
Kwun Yam Beach  
Grade 3 beaches are:
Anglers' Beach Hoi Mei Wan Beach
Approach Beach Lido Beach
Butterfly Beach Ma Wan Tung Wan Beach
Casam Beach Ting Kau Beach
Deep Water Bay Beach  
Grade 4 beach is:
Big Wave Bay Beach**  

* Discovery Bay is a non-gazetted beach without lifeguard service.
** Big Wave Bay Beach has been temporarily closed since June 4 due to urgent works by the Drainage Services Department at a nearby stream and the very poor (Grade 4) water quality measured by the EPD. The beach will be closed until further notice.

     Compared with the grading released last week, Stanley Main Beach has been upgraded from Grade 2 to Grade 1, and Silver Mine Bay Beach from Grade 3 to Grade 2. Kwun Yam Beach has been changed from Grade 1 to Grade 2, and Deep Water Bay Beach from Grade 2 to Grade 3.

     "Big Wave Bay Beach has been rated as Very Poor (Grade 4) since June 5, which was largely due to the recent unsteady weather and frequent heavy rain. 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 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 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 website on Beach Water Quality (www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666.
