CONCLUSION




Water is important in sustaining life however,
provision of safe drinking water is a challenge all
over the world due to :
The presence of microorganisms in drinking water
which could give rise to waterborne infections such
as typhoid fever, diarrhoea, hepatitis E, cholera .
The presence of chemicals that could arise from
water treatment & cleaning of equipment, packaging
materials, source of water supply etc. This could lead
to organ diseases in consumers.
3

Trade in packaged water has increased
globally due to water shortage and the
recognition that traditional drinking water
supplies such as public and private
waterworks may not always be able to
guarantee the microbiological, chemical and
physical safety of water to the extent
previously thought possible.

1. Borehole Water
 The depth of the drilled borehole must not be
below the sea level and it should be equipped
with a submersible, pump to pump out water.
 The
borehole must be suitably positioned
topographically from the septic tank and there
must be a good distance (e.g . 30 metres)
separating the two of them.
 The minimum depth of the borehole should be
150ft. (depends on the topography).
Note: Well water is not acceptable
5
2. Public Mains Water
The water must be running freely in the factory
lifting of water with tankers from another
location to the factory is not acceptable, in order
to avoid cross contamination of the water.
3. Spring water:
Collected into a reservoir at the shortest possible
distance from the source to prevent
environmental pollution. There should be no
need to subject this source of water to chemical
treatment.

The Nigerian Industrial standard(NIS) i.e standards
organization of Nigeria (SON) standards cover physical and
chemical characteristics namely:
Physical &organoleptic colour, taste, odour, temperature and
turbidity.
Chemical characteristic: maximum permitted levels of
inorganic constituents such as chloride, fluoride, copper,
iron, nitrate, manganese, magnesium, zinc, sulphide, total
dissolved solids, PH, hardness( as caco3) & conductivity.
Organic constituents : maximum permitted levels of
polynuclear aromatic hydrocarbons such as 3,4benzfluoranthene,11,12,-3,4Benzpyrene indeno (1,2,4-cd-pyrene)

NAFDAC Guidelines on Production and
Registration of Packaged Water stipulates
that:
 No packaged water shall be manufactured,
advertised, sold or distributed in Nigeria
unless it has been registered in accordance
with the provisions of Act Cap F33 LFN 2004
and the accompanying regulations &
guidelines.



All
sourced
water
require
some
form
of
treatment
before
consumption, the treated water must be controlled constantly to
ensure that the quality of water reaching consumers are not
compromised along the treatment networks.

It is important that drinking water is monitored regularly to
ascertain
the
level
of
quality
characteristic
first
and
the
presence/nature of any pollution within the treatment network.

Any information desired from quality monitoring will subsequently
be used in determining the type and degree of treatment required or
control measures to be effected to make the water portable again
and to guarantee its safety to the consumers.
11

The water quality criteria that determine portability are
basically
classified
as
physical,
chemical
these
parameters
and
microbiological.

Constant
monitoring
of
by
manufacturers help to detect accidental critical events
including their sources that may result in quick and
unusual amounts of contaminants into the source or
drinking water.


The importance of safe drinking water cannot be over
emphasized because of the serious health implications and
the effect on morbidity and mortality of any nation.
Water producers must therefore improve on their Good
Manufacturing Practices (GMP) to gain consumer confidence
which will increase productivity, job creation and improved
earnings.
There is need for collaboration with NAFDAC to safeguard
the health of Nigerians.
