Grading of beach water quality released
The Environmental Protection Department (EPD) today (November 18) released the latest grading of water quality of eight beaches open for swimming. Other beaches have been closed to swimmers from November 1, 2011 for the winter season.
All eight beaches were rated as Good (Grade 1).
The Grade 1 beaches are:
|
Big Wave Bay Beach
Clear Water Bay Second Beach
Deep Water Bay Beach
Golden Beach
|
Middle Bay Beach
Repulse Bay Beach
Silverstrand Beach
Stanley Main Beach
|
These are all gazetted beaches equipped with shark nets.
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.
Noting that a red tide has recently affected Deep Water Bay Beach in South District, an EPD spokesman advised the public to check the latest update from the Leisure and Cultural Services Department before swimming.
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.
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.
