GRADING OF BEACH WATER QUALITY
THE ENVIRONMENTAL PROTECTION DEPARTMENT (EPD) TODAY (THURSDAY) ANNOUNCED THE LATEST GRADES ON THE BACTERIAL 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 BACTERIAL POLLUTION AT VARIOUS BEACHES.
THE GRADING IS BASED ON THE E. COLI DATA OBTAINED BY THE EPD IN ITS ROUTINE BEACH WATER QUALITY MONITORING PROGRAMME.
THE E. COLI DATA USED FOR GRADING ARE BASED ON THE MEDIAN VALUES OF THE MOST RECENT FIVE RESULTS, OBTAINED OVER A TWO AND A HALF MONTH PERIOD ACCORDING TO THE USUAL SAMPLING FREQUENCY.
THE GRADES FOR SOME BEACHES MAY FLUCTUATE. THIS REPRESENTS A NATURAL FLUCTUATION IN THE BACTERIAL QUALITY OF THE BEACHES IN MOST CASES, AS RAIN AND TIDES BRING MORE OR LESS POLLUTION TO THE SWIMMING AREAS.
NEVERTHELESS, THE GRADES GIVE A GOOD GENERAL PICTURE OF THE BACTERIAL WATER QUALITY OF BEACHES, AND FORM THE BEST AVAILABLE FORECAST OF BEACH WATER QUALITY IN THE IMMEDIATE FUTURE.
THE SYSTEM FOR GRADING BEACH WATER QUALITY IS AS FOLLOWS:
'A' GRADE INDICATES THE MEDIAN E. COLI COUNT IS BETWEEN
0-99 PER 100 MILLILITRES, AND THE WATER QUALITY IS GOOD.
/'B' GRADE
