Grading of beach water quality released
The Environmental Protection Department today (August 25) released the latest grading of water quality of 33 beaches.
Nineteen beaches were rated as Good (Grade 1), eight were rated as Fair (Grade 2), five were rated as Poor (Grade 3) and one was rated as Very Poor (Grade 4).
Grade 1 beaches are:
Cheung Chau Tung Wan Beach Pui O Beach
Chung Hom Kok Beach Repulse Bay Beach
Deep Water Bay 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 Turtle Cove Beach
Lower Cheung Sha Beach Upper Cheung Sha Beach
Middle Bay Beach
Grade 2 beaches are:
Big Wave Bay Beach Kwun Yam Beach
Butterfly Beach Shek O Beach
Clear Water Bay Second Beach Silver Mine Bay Beach
Clear Water Bay First Beach Silverstrand Beach
Grade 3 beaches are:
Cafeteria Old Beach Kadoorie Beach
Castle Peak Beach Ma Wan Tung Wan Beach
Golden Beach
Grade 4 beach is Cafeteria New Beach.
The beach with an asterisk is a non-gazetted beach. All gazetted beaches are equipped with shark nets.
Beach grades are published weekly before the weekend. The information may also be obtained from the department's website at www.epd.gov.hk or the beach hotline, 2511 6666.
Compared with the grading released last week, Cheung Chau Tung Wan Beach and Lower Cheung Sha Beach have been upgraded from Grade 2 to Grade 1.
Kwun Yam Beach and Shek O Beach have been changed from Grade 1 to Grade 2, and Cafeteria New Beach has been changed from Grade 3 to Grade 4.
"The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches except for Cafeteria New Beach," a spokesman said.
"The very poor water quality of Cafeteria New Beach is due to the previous heavy rain which flushed pollutants from the beach hinterland into the water,” he added.
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.
Grade 4 is assigned to beaches whose last E. coli reading exceeded a threshold figure, irrespective of the geometric mean. Swimmers are advised to avoid these beaches until the water quality improves.
Seven gazetted beaches -- Anglers' Beach, Approach Beach, Ting Kau Beach, Casam Beach, Gemini Beaches, Hoi Mei Wan Beach and Lido Beach -- are closed to swimmers year round because of poor water quality.
People are advised not to swim at the closed beaches.
The spokesman 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.
