The Environmental Protection Department (EPD) today (August 10) released the latest grading of water quality of 38 gazetted beaches and one non-gazetted beach (Discovery Bay) that are open for swimming.
Twenty-three beaches were rated as good (Grade 1), 15 as fair (Grade 2) and one as poor (Grade 3).
Grade 1 beaches are:
| Cafeteria New Beach | Lower Cheung Sha Beach |
| Cafeteria Old Beach | Middle Bay Beach |

| Chung Hom Kok Beach | Repulse Bay Beach |
| Clear Water Bay Second Beach | Silverstrand Beach |

| Casam Beach | Silver Mine Bay Beach |
| Clear Water Bay First Beach | Stanley Main Beach |
| Discovery Bay | Ting Kau Beach |

Grade 3 beach is:

Compared with the grading released last week, Clear Water Bay Second Beach and Silverstrand Beach have been upgraded from Grade 2 to Grade 1; Ting Kau Beach from Grade 3 to Grade 2. Stanley Main Beach has been changed from Grade 1 to Grade 2.
"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. 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.
