GRADING OF BEACH WATER QUALITY
4.
(THURSDAY}
THE ENVIRONMENTAL PROTECTION DEPARTMENT (EPD) TODAY ANNOUNCED GRADES ON THE BACTERIOLOGICAL WATER QUALITY OF ALL BATHING BEACHES IN HONG KONG.
THE PURPOSE OF THE GRADING SYSTEM IS TO INFORM SWIMMERS AND THE GENERAL PUBLIC ABOUT THE STATE OF BACTERIOLOGICAL POLLUTION AT VARIOUS BEACHES.
AN EPD SPOKESMAN SAID THE GRADING WILL BE ANNOUNCED AT BIWEEKLY INTERVALS DURING THE BATHING SEASON, то COINCIDE WITH THE FREQUENCY AT WHICH BEACH WATERS ARE USUALLY SAMPLED.
THE GRADING IS BASED ON THE MOST RECENT E. COLI DATA OBTAINED BY THE EPD IN ITS ROUTINE MONITORING PROGRAMME.
AS WITH LAST YEAR, THE GRADING ALSO INCLUDES AN ESTIMATE OF THE RISK OF SUFFERING SOME MINOR SKIN OR GASTROINTESTINAL COMPLAINTS AS A RESULT OF SWIMMING AT A BEACH THAT HAS SOME DEGREE OF POLLUTION.
THE ESTIMATE IS BASED ON A VERY LARGE BODY OF STATISTICAL INFORMATION GATHERED IN HONG KONG IN RECENT BATHING SEASONS.
