Grading of beach water quality released
     The Environmental Protection Department (EPD) today (July 21) 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), seventeen as Fair (Grade 2) and ten as Poor (Grade 3).
Grade 1 beaches are:
Discovery Bay South Bay Beach
Hap Mun Bay Beach St Stephen's Beach
Hung Shing Yeh Beach Stanley Main Beach
Kiu Tsui Beach Trio Beach
Lo So Shing Beach Upper Cheung Sha Beach
Repulse Bay Beach  
Grade 2 beaches are:
Anglers' Beach Lower Cheung Sha Beach
Cafeteria New 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 Silverstrand Beach
Deep Water Bay Beach Tong Fuk Beach
Kadoorie Beach Turtle Cove Beach
Kwun Yam Beach  
Grade 3 beaches are:
Approach Beach Castle Peak Beach
Big Wave Bay Beach Golden Beach
Butterfly Beach Hoi Mei Wan Beach
Cafeteria Old Beach Lido Beach
Casam Beach Ting Kau Beach
     Compared with the grading released last week, Trio Beach has been upgraded from Grade 2 to Grade 1, and Clear Water Bay Second Beach and Pui O Beach from Grade 3 to Grade 2. Chung Hom Kok Beach and Turtle Cove Beach have been changed from Grade 1 to Grade 2; Castle Peak Beach and Golden Beach from Grade 2 to Grade 3.
     "The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches," the EPD spokesman said.
     Under our 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 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.
     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.
