Abstract:
Water is important for hydration and ,
consequently, for life. It is also essential in food
preparation and cooking, sanitation and hygiene and
for different uses. The safe drinking water must be
free from all hazardous materials and contaminant.
Nature has provided enough drinking water
resources for living organisms through rain, springs,
rivers, lakes/ponds and subsurface resources.
However, due to non availability of safe drinking
water at all places and limited drinking water supply,
people started opting commercial products for
treating their water supply at domestic and
community level without knowing much about its
technologies adopted in these commercial products
and assuming that the treated water from these
products are a symbol for high purity potable water.
Different chemicals such as pesticides, disinfection
by product are the subject of interest while some
other constituents are out of focus. There are certain
elements which play an important role in human
health, representing essential elements for human
body activities. Calcium and magnesium are major
representatives of these types of constituents.
