Hello Hussein,This discussion ...

Hello Hussein, This discussion is very critical because it defines exactly the situation as it is in some of our rural areas where the profession is predominantly agriculture. Of course with increase in population world-wide and the need for food production at large scale to meet the food challenge, different strategies have been employed ranging from mechanization and the use of agro-chemicals. All these are washed into pond and other forms of stagnant water which the rural people unknowingly fetch for their domestic uses; be it drinking or cooking etc. Added to what you earlier mentioned, there is a purification system that is called slow sand filtration which is less expensive and can be adapted in rural areas to purify such water apart from the use of chemicals.
