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.
