The Environmental Protection Department (EPD) today (January 13) released the latest grading of water quality of four gazetted beaches which are open all year round for swimming.
Four beaches were rated as Good (Grade 1).
Grade 1 beaches are:
Clear Water Bay Second Beach
Deep Water Bay 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 websites on Beach Water Quality (www.beachwq.gov.hk or www.epd.gov.hk/epd/beach) 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 suspected red tides have recently affected Deep Water Bay Beach in Southern District and Golden Beach in Tuen Mun District, the EPD spokesman advised the public to check the latest update from the Leisure and Cultural Services Department before swimming.
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.
