Press Release
Grading of beach water quality released
The Environmental Protection Department today (November 7) released the latest grading of water quality of eight beaches open for swimming. Other beaches have been closed to swimmers from November 1, 2008 for the winter season.
Seven beaches were rated as Good (Grade 1) and one was rated 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
Silverstrand Beach
Stanley Main Beach
Grade 2 beach is:
Golden Beach
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 website on Beach Water Quality or the beach hotline, 2511 6666.
Compared with the grading released last week, there was no change in the grading for these beaches.
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, Casam Beach, Gemini Beaches, Hoi Mei Wan Beach, Lido Beach and Ting Kau 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.
