PARETO DIAGRAM
• A pareto chart, also called a pareto distribution diagram, was named after vilfredo pareto has both lines graph and bars.
• The bars represent the individual values in the decreasing order from left to right and the line represents the cumulative total.
• The pareto chart provides a graphic depiction of the pareto principle, which states that 80% of the output is produced by 20% of the input.
• In simple words 80% of total problems are caused by only 20% of input factors.
• Applications of Pareto Chart: Used to analyze data about the frequency of problems
or causes in a process. Used when there are many problems or causes and
you want to focus on the most significant. Used while analyzing broad causes by looking at their
specific components.
SURFACE WATER CONTAMINATION
Waste that end up in water bodies negatively change the chemical
composition of the water. Technically, this is called water pollution. This will
affect all ecosystems existing in the water. It can also cause harm to animals
that drink from such polluted water.
SOIL CONTAMINATION
Hazardous chemicals that get into the soil (contaminants) can harm plants when
they take up the contamination through their roots. If humans eat plants and
animals that have been in contact with such polluted soils, there can be negative
impact on their health.
POLLUTIONBad waste management practices can result in land and air pollution and can cause respiratory problems and other
adverse health effects as contaminants are absorbed from the lungs into other parts
of the body.
LEACHATE Liquid that forms as water
trickles through contaminated areas is called Leachate. It forms
very harmful mixture of chemicals that masy result in
hazardous substances entering surface water, groundwater or
soil.

LEARNING’S
We learned the concept of ‘vital few and the useful many’, according to which one need to focus on those 20% factors which contribute to the 80% of the output.
We came to know about the major source of pollution and garbage in the city.
We also realized on which factors we need to focus in order to lower down the garbage level in the city.
We realized how important is ‘Pareto Chart’ as a quality tool.
Very helpful in decision making.
Pareto Analysis not only shows us the most important problem to solve, it also gives us a score showing how severe the problem is.
