-assurance that accepted procedures

available for determination of STANDARD

-adherence to the procedures allowscomparability of results of analysis within asingle laboratory and between laboratories.

technical aspect:physical bacteriological,

chemical,biological and radiological examinations of water ,

should be a registered: pharmacist,medical technologist,or chemist.

must have been trained and musthave at least 1 year experience.

may supervise not more than two

skilled workers .


14/49

Laboratory support personnelsuch as;laboratory aides - are needed to clean glassware's, assist in thepreparation of media.

Each service must therefore be operated by at least oneregistered professional, one laboratory aide .

Bacteriological service-----handle at most 30 samples/day

Chemical service -----5 samples for routine chemistry .


15/49

Work rooms must be:house in a permanent buildingWell-ventilated

correlate with the volume and type of workA bench height of 90 cm providesconvenience for workers

adequate running water.Adequate physical provisions for the safetyof the laboratory personnel must beprovided.

Quality -to meet the levels of sensitivity,reliability and should only need

minimum service repair.Increased workloadEfficiency and effectively.Highest grade of quality media andreagent are to be used

In every glass of water we drink, some of the water has already passed through fishes, trees, bacteria,

worms in the soil, and many other organisms,including people...Living systems cleanse water and

make it fit, among other things, for humanconsumption.
