The Environmental Protection Department (EPD) today (June 6) released the latest grading of water quality for 38 gazetted beaches that are open for swimming and one non-gazetted beach (i.e. Discovery Bay*).

*: Discovery Bay is a non-gazetted beach without lifeguard service.

Compared with the grading released last week, Lower Cheung Sha Beach has been upgraded from Grade 4 to Grade 2; Kiu Tsui Beach and Trio Beach from Grade 2 to Grade 1. Pui O Beach, Shek O Beach and Stanley Main Beach have been changed from Grade 1 to Grade 2; Ting Kau Beach from Grade 2 to Grade 3; Big Wave Bay Beach from Grade 3 to Grade 4.

"The deterioration of water quality in Big Wave Bay Beach was due to the frequent heavy rain since late May, while the changes in other beaches 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.  The latest beach grades based on the most current data may be obtained from the department's website on Beach Water Quality (www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666.
