VERY INFORMATION GATHERED IN HONG KONG DURING RECENT BATHING SEASONS.

THE SUMMER. THIS OF BATHING LESS POLLUTION

THE GRADING OF SOME BEACHES MAY VARY DURING REPRESENTS A NATURAL FLUCTUATION IN THE BACTERIAL QUALITY WATERS IN MOST CASES, AS RAIN AND TIDES BRING MORE OR TO THE BEACHES.

DURING BATHING WATERS COMMONLY BECOME WORSE DUE TO HEAVY USAGE

PICTURE OF THE THE SUMMER. HOWEVER, THE GRADES GIVE A GOOD GENERAL

OF REPORTING AND FORM WATER QUALITY AT BATHING BEACHES AT THE TIME THE BEST AVAILABLE FORECAST FOR THE IMMEDIATE FUTURE.

THE SYSTEM FOR GRADING BEACH WATER QUALITY IS AS FOLLOWS:

THE IS GOOD. "A" GRADE INDICATES THAT THE WATER QUALITY

HEALTH RISK IS LESS BEACH SO GRADED, AND THE EXPECTED SEVEN CASES OF MINOR ILLNESS PER 1,000 SWIMMERS.

"B" GRADE INDICATES THAT THE WATER QUALİTY IS MEAN E. COLT COUNT IS LESS THAN 1,000 PER EACH BEACH 80 GRADED, AND THE EXPECTED HEALTH RISK IS LESS THAN T8 CASES OF MINOR ILLNESS PER 1,000 NWIMMERS.

POOR. THE MEAN "C" GRADE INDICATES THAT THE WATER QUALITY IS

I'ER 100 MILLILITRES AT E. COLI COUNT IS 1,000 OR MORE

EACH IS 18 OR MORE BEACH SO GRADED, AND THE EXPECTED HEALTH RISK CASES OF MINOR ILLNESS PRR 1,000 SWIMMERS.

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

CONSIDERED

NORMALLY, A RECOMMENDATION ON CLOSURE WOULD ONLY BE BY THE URBAN OR REGIONAL COUNCIL IF A "C" GRADING OCCURRED REPEATEDLY, SEASON EXCEEDED 15 SO THAT THE AVERAGE HEALTH RISK OVER THE BATHING
