A summary of beach grades is published weekly before the weekend. The 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 and www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666.
Compared with the grading released last week, South Bay Beach has been upgraded from Grade 2 to Grade 1 and Clear Water Bay Second Beach has been changed from Grade 2 to Grade 3. Since its last grading (Grade 4) earlier this week, Butterfly Beach has been upgraded to Grade 3.
"The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches," the EPD spokesman said.
"For Butterfly Beach, we observed that temporary deterioration of water quality was largely due to heavy rain. The latest samples taken show that the water quality of the beach has improved."
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.
