The Environmental Protection Department (EPD) today (March 3) released the latest grading of water quality of eight gazetted beaches that are open for swimming.
Among them, Clear Water Bay Second Beach, Deep Water Bay Beach, Golden Beach and Silverstrand Beach are open to swimmers all year round.
Four other beaches, namely Big Wave Bay Beach, Middle Bay Beach, Repulse Bay Beach and Stanley Main Beach in the Southern District, are open for swimming since March 1.
Seven beaches were rated as Good (Grade 1) and one as Fair (Grade 2).
Grade 1 beaches are:
Big Wave Bay Beach
Clear Water Bay Second Beach
Deep Water Bay Beach
Middle Bay Beach
Repulse Bay Beach
Stanley Main Beach
Grade 2 beach is:
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.
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.
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.
People are advised not to swim at the closed beaches.
The EPD 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.
