Grade 3 beaches are：
Clear Water Bay Second Beach
Hoi Mei Wan Beach
Ma Wan Tung Wan Beach
Ting Kau Beach
Compared with the grading released last week, Discovery Bay has been upgraded from Grade 2 to Grade 1, Casam Beach from Grade 3 to Grade 2. Big Wave Bay Beach, Deep Water Bay Beach, Kwun Yam Beach and Stanley Main Beach have been changed from Grade 1 to Grade 2; Clear Water Bay Second Beach, Ma Wan Tung Wan Beach and Ting Kau Beach from Grade 2 to Grade 3.
“The changes are generally within the normal range of fluctuation of the bacteriological water quality of the beaches,” an EPD spokesman said.
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.
While the ratings represent the general water quality at the beaches, the EPD spokesman reminded members of the public that water quality could be temporarily affected during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a storm or heavy rainfall.
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.
