Water
u A commodity one cannot live without
u One of the elements of life
u One needs to make sure that the water being delivered in the
communities must be duly accredited as safe and potable.
u Those who are dealing with the determination of safe and potable
water should embrace the concept that water analysis is not for
commercial enterprise but for the assistance and maintenance of safe
and potable quality of water supply
