Nearly all water in the world contains contaminants, even in the absence of nearby pollution-causing activities Many dissolved minerals, carbon compounds, and microbes find their way into drinking water as it comes in contact with air and soil When pollutant and contaminant levels in drinking water are high, they may affect household routines and be detrimental to human health The only way to ensure that your water supply is safe is to have a periodic laboratory water quality analysis done on your drinking water. Hach India is the leading provider of high end water quality analysis equipment in india

2. Why Test Your Water?
 Nearly all water in the world contains
contaminants
 Many dissolved minerals, carbon
compounds, and microbes find their
way into drinking water
 Pollutants in drinking water may affect
household routines and human health
 The only way to ensure safety of your
water supply is to have a periodic
laboratory water analysis done

3. Water Testing Parameters
 Color
Color in water may be due to the inorganic ions, such as iron and
manganese, humus and peat materials, plankton, weeds and industrial wastes.
 Odor
Odor is recognized as a quality factor affecting acceptability of drinking water. Most
organic and some inorganic chemicals contribute odor.
 Turbidity
The Turbidity in water is the reduction of transparency due to the presence of
particulate matter such as clay or silt, finely divided organic matter, plankton or
other microscopic organisms.

4. Water Testing Parameters
 Manganese
The intake of manganese can be high as 20 mg/day without apparent ill effects. It
should be noted that manganese may be objectionable to consumers if it is
deposited in water mains and causes water discoloration
 Iron
Anaerobic ground waters may contain iron up to several milligrams per liter without
causing discoloration or turbidity in the water.
 Calcium
Calcium is a major constituent of various types of rock. It is one of the most
common constituents present in natural waters ranging from zero to several
hundred milligrams per liter.

5. Water Testing Parameters
 pH value
pH value is the logarithm of reciprocal of hydrogen ion activity in moles per liter. In
water solution, variations in pH value are mainly due to hydrolysis of salts of strong
bases and weak acids.
 Alkalinity
Alkalinity of water is its quantitative capacity to react with a strong acid to a
designated pH. Excess alkalinity in water is harmful for irrigation which leads to soil
damage and reduce crop yields.
 Conductivity
Specific conductance yields a measure of water’s capacity to convey an electric
current.

6. Important Water Analysis Equipment
 Total Organic Carbon Analyzer (TOC)
A total organic carbon analyzer
determines the amount of carbon in a
water sample. There are two types of
analyzers. One uses combustion and
the other chemical oxidation.
 pH Analyzer
Water pH testers and analyzers help
analyze pH levels and detect faults in
systems with electronic pH meters.

8. Important Water Analysis Equipment
 Water Desalination Equipment
The parameters measured in
Desalination instruments include
Alkalinity, (COD), Conductivity, Dissolv
ed Oxygen, Water
Hardness, Iron, Manganese, Turbidity
in water etc.

9. Important Water Analysis Equipment
 ORP Meters
ORP meters measure the very small
voltages generated when the
measuring probe is placed in water in
the presence of an oxidizing agent.
