Since water is essential to sustain life, its satisfactory supply must be made available to consumers. Despite the fact that the 'right to drinking water' is now a part of human rights, one-sixth of the world population still does not have access to safe drinking water. The World Health Organization (WHO) estimated that up to 80% of all sicknesses and diseases in the world are caused by inadequate sanitation, polluted water, or unavailability of water. In India, about 21% of all communicable diseases are water-borne, and among them, diarrhoea is responsible for 25-30% of deaths among children below the age of five years.
Keeping these points in view, the PAU's Department of Microbiology has developed a simple, portable, and inexpensive bacteriological water testing kit to determine the easy potability of drinking water. This kit is available in the Department of Microbiology for Rs40 only.
How to use kit:
Cut open the aluminum foil and keep the rubber stopper intact.
Open the kit near a water source and the water sample to be tested or screened for bacteriological potability should be aseptically dispensed in kit bottles up to the calibrated mark (approximately 15ml).
Allow the kit to stand at a warm place for 24 hours.
Bacterial contamination is indicated when the content of the kit bottle shows a change in colour, turbidity, sediments, pellicle, and popping of lid within 12 hours.
For disposal of the kit, add four drops of dettol/disinfectant in the kit before disposal.
Antibiotic susceptibility of consortia can be directly done.
Advantage of PAU kit:
It is the cheapest method known so far.
It is very handy to use.
To perform the test, one needs to add water to the kit and leave it aside.
No equipment is required.
Colour change denotes the presence of microbes.
