Grading of beach water quality released

     The Environmental Protection Department (EPD) today (November 12) released the latest grading of water quality for nine gazetted beaches that are open for swimming in November.

     Seven beaches were rated as Good (Grade 1) and two as Fair (Grade 2).
 
Grade 1 beaches are:

Clear Water Bay Second Beach Repulse Bay Beach
Deep Water Bay Beach Silverstrand Beach
Golden Beach Stanley Main Beach
Middle Bay Beach  

 
Grade 2 beaches are:

Big Wave Bay Beach Silver Mine Bay Beach

     Compared with the grading released last week, Golden Beach, Middle Bay Beach and Silverstrand Beach have been upgraded from Grade 2 to Grade 1, and Silver Mine Bay Beach from Grade 3 to Grade 2.
 
     Under the present grading system, beaches are classified into four grades, namely Good (Grade 1), Fair (Grade 2), Poor (Grade 3) and Very Poor (Grade 4), 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, an 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 EPD's website on Beach Water Quality (www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666.
