***************************************
The Environmental Protection Department (EPD) today (April 30) released the latest grading of water quality of 39 beaches.
Thirty-four beaches were rated as Good (Grade 1) and five were rated as Fair (Grade 2).
Grade 1 beaches are:
Big Wave Bay Beach Kiu Tsui Beach

Grade 2 beaches are:
Anglers' Beach Shek O Beach
Approach Beach Ting Kau Beach
Lido Beach
The beach with an asterisk is a non-gazetted beach. All gazetted beaches are equipped with shark nets.
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.
Compared with the grading released last week, Castle Peak Beach, Clear Water Bay First Beach and Stanley Main Beach have been upgraded from Grade 2 to Grade 1. Lido 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.
Noting that a suspected red tide has recently affected Turtle Cove Beach in Southern District, the EPD spokesman advised the public to check the latest update from the Leisure and Cultural Services Department before swimming.
Under our 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.
Grade 4 is assigned to beaches whose last E coli reading exceeded a threshold figure, irrespective of the geometric mean. Swimmers are advised to avoid these beaches until the water quality improves.
People are advised not to swim at the closed beaches.
The EPD spokesman warned that many beaches were likely to be more polluted than their grades suggested during and after periods of heavy rain. Bathers should avoid swimming at beaches for up to three days after a storm or heavy rainfall.
Meanwhile, the department has published the report "Beach Water Quality in Hong Kong 2014". The report summarises the water quality of gazetted beaches in 2014 and is accessible online at www.beachwq.gov.hk and www.epd.gov.hk.
