AN EPD SPOKESMAN SAID THE GRADING IS BASED ON THE E. COLI DATA ROUTINE BEACH WATER IN ITS

QUALITY MONITORING OBTAINED BY EPD PROGRAMME. THE E. COLI DATA USED FOR GRADING ARE BASED ON THE VALUES OF THE MOST RECENT FIVE RESULTS, OBTAINED OVER A PERIOD OF AND A HALF MONTHS ACCORDING TO THE USUAL SAMPLING FREQUENCY.

THIS REPRESENTS A THE GRADES FOR SOME BEACHES MAY FLUCTUATE.

BEACHES IN MOST NATURAL FLUCTUATION IN THE BACTERIAL QUALITY OF THE

SWIMMING CASES, AS RAIN AND TIDES BRING MORE OR LESS POLLUTION TO THE AREAS.

FORM THE BEST AVAILABLE BACTERIAL WATER QUALITY FORECAST OF BEACH WATER QUALITY IN THE IMMEDIATE FUTURE.

THE SYSTEM OF GRADING BEACH WATER QUALITY IS AS FOLLOWS:

IS BETWEEN 0-99

"A" GRADE INDICATES THE MEDIAN E. COLI COUNT PER 100 MILLILITRES, AND THE WATER QUALITY IS GOOD.

"B" GRADE 100-999 ACCEPTABLE.
