Grading of beach water quality released
***************************************

     The Environmental Protection Department (EPD) today (May 19) released the latest grading of water quality for 37 gazetted beaches and one non-gazetted beach (Discovery Bay) that are open for swimming.

     Twenty-three beaches were rated as Good (Grade 1), fourteen as Fair (Grade 2) and one as Poor (Grade 3).

Grade 1 beaches are:
Casam Beach Lower Cheung Sha Beach
Cheung Chau Tung Wan Beach Middle Bay Beach
Chung Hom Kok Beach Pui O Beach
Clear Water Bay Second Beach Repulse Bay Beach
Discovery Bay Silverstrand Beach
Golden Beach South Bay Beach
Hap Mun Bay Beach St Stephen's Beach
Hung Shing Yeh Beach Tong Fuk Beach
Kiu Tsui Beach Trio Beach
Kwun Yam Beach Turtle Cove Beach
Lido Beach Upper Cheung Sha Beach
Lo So Shing Beach  

Grade 2 beaches are:
Anglers' Beach Deep Water Bay Beach
Approach Beach Hoi Mei Wan Beach
Big Wave Bay Beach Kadoorie Beach
Butterfly Beach Ma Wan Tung Wan Beach
Cafeteria New Beach Shek O Beach
Cafeteria Old Beach Stanley Main Beach
Clear Water Bay First Beach Ting Kau Beach

Grade 3 beach is:
Castle Peak Beach

     Compared with the grading released last week, Silverstrand Beach has been upgraded from Grade 2 to Grade 1. Big Wave Bay Beach, Cafeteria New Beach, Cafeteria Old Beach, Clear Water Bay First Beach, Ma Wan Tung Wan Beach, Shek O Beach and Stanley Main Beach have been changed from Grade 1 to Grade 2, and Castle Peak Beach from Grade 2 to Grade 3. Since their last grading (Grade 4) on May 16, Butterfly Beach and Kadoorie Beach have been upgraded 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.

     "For Butterfly Beach and Kadoorie Beach, we observed that the earlier temporary deterioration of water quality (sampled on May 15) was due to heavy rain. The latest samples taken show that the water quality of the beaches has improved."

     The EPD spokesman also 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.

     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. The 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 and www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666.
