Grading of beach water quality released

     The Environmental Protection Department (EPD) today (January 4) released the latest grading of water quality for four gazetted beaches which are open all year round for swimming. 
   
     Four beaches were rated as Good (Grade 1).
 
Grade 1 beaches are:

Clear Water Bay Second Beach  
Golden Beach  
Repulse Bay Beach  
Silverstrand Beach  
 
     Compared with the grading released last week, there was no change in the grading for these beaches.
      
     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, 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 department’s website on Beach Water Quality (www.epd.gov.hk/epd/beach) or the beach hotline, 2511 6666. read more

Red tide sighted

     Three red tides have been sighted, an inter-departmental red tide working group reported today (January 4).
 
     One red tide was spotted by staff of the Leisure and Cultural Services Department at Stanley Main Beach, Hong Kong Island, on January 2. The red tide has dissipated.
 
     In addition, mariculturists spotted two red tides at Long Harbour and Sham Wan fish culture zone on January 2 and 4 respectively. The red tides still persist.
 
     No associated death of fish has been reported so far in all three red tides.
 
     A spokesman for the working group said, “Three red tides were formed by Mesodinium rubrum, which is commonly found in Hong Kong waters and is non-toxic.”
 
     The Agriculture, Fisheries and Conservation Department (AFCD) urged mariculturists at Lo Tik Wan, Sok Kwu Wan, Po Toi, Tap Mun, Kau Lau Wan and Sham Wan fish culture zones to monitor the situation closely and increase aeration where necessary.
 
     Red tide is a natural phenomenon. The AFCD’s proactive phytoplankton monitoring programme will continue monitoring red tide occurrences to minimise the impact on the mariculture industry and the public. read more
