THE SYSTEM FOR GRADING BEACH WATER QUALITY IS AS BELOW:
A GRADE INDICATES THE MEDIAN E. COLI COUNT IS BETWEEN 100 MILLILITRES, AND THE WATER QUALITY IS GOOD.
0-99 PER
IS BETWEEN 100-999
B GRADE INDICATES THE MEDIAN E.COLI COUNT PER 100 MILLILITRES, AND THE WATER QUALITY IS ACCEPTABLE.
C GRADE INDICATES THE MEDIAN E.COLI COUNT IS 1000 OR MORE PER 100 MILLILITRES, AND THE WATER QUALITY IS POOR.
HE SAID THE DECISION WHETHER OR NOT TO CLOSE A BEACH TO SWIMMERS IS BASED ON A JUDGEMENT OF WHAT DEGREE OF POLLUTION
IS ACCEPTABLE. NORMALLY, A RECOMMENDATION ON CLOSURE WOULD ONLY NEED ΤΟ BE CONSIDERED BY THE URBAN COUNCIL OR REGIONAL COUNCIL IF A "C" GRADING OCCURRED REPEATEDLY. SIMILARLY A RECOMMENDATION ΤΟ REOPEN A CLOSED BEACH WOULD ONLY BE CONSIDERED IF A "B" GRADE OR BETTER WERE CONSISTENTLY OBTAINED. THIS IS IN LINE WITH THE RECOMMENDATIONS OF THE WORLD HEALTH ORGANISATION.
