THE SYSTEM FOR GRADING BEACH WATER QUALITY IS AS FOLLOWS:

E.

COLI COUNT IN BETWEEN

"A" GRADE INDICATES THE MEDIAN

0-99 PER 100 MILLILITRES, AND THE WATER QUALITY IS GOOD.

"B" GRADE INDICATES THE MEDIAN

E.

COLI COUNT 13 BETWEEN 100-999 PER 100 MILLILITRES, AND THE WATER QUALITY IS ACCEPTABLE.

"C" GRADE INDICATES THE MEDIAN B. COLI COUNT IS 1,000 OR MORE

PER 100 MILLILITRES, AND THE WATER QUALITY IS POOR.

THE DECISION WHETHER OR NOT TO CLOSE A BRACH TO SWIMMERS 18 BASED ON A JUDGEMENT OF WHAT DEGREE OF POLLUTION IS ACCEPTABLE.

NORMALLY, A RECOMMENDATION ON CLOSURE WOULD ONLY BE CONSIDERED BY THE URBAN OR THE REGIONAL COUNCIL IF A "C" GRADING OCCURRED REPEATEDLY. SIMILARLY, A RECOMMENDATION TO REOPEN A CLOSED BEACH WOULD ONLY BE CONSIDERED IF A "B" GRADE OR BETTER WERE CONSISTENTLY OBTAINED.

AT PRESENT, FIVE BATHING BEACHES HAVE BEEN DECLARED UNSUITABLE FOR SWIMMING PURPOSES, BASED ON THE WATER QUALITY DURING PAST SEASONS.

THESE BEACHES ARE ANGLERS* CASTLE PEAK,

*

SILVERMINE BAY, OLD CAFETERIA AND ROCKY BAY. THEY ARE POLLUTED BY FAECAL WASTES AND FAILED TO ACHIEVE CONSISTENTLY THE WORLD HEALTH ORGANISATION AND HONG KONG STANDARDS. THE PUBLIC ARE ADVISED NOT TO SWIM IN THESE FIVE BEACHES. THEY ARE IDENTIFIED BY AN "X" IN THE FOLLOWING TABLE.
