About Ground Water: Groundwater is an important part of the water cycle. Groundwater is the part of precipitation that seeps down through the soil until it reaches rock material that is saturated with water. Water in the ground is stored in the spaces between rock particles . Groundwater slowly moves underground, generally at a downward angle (because of gravity), and may eventually seep into streams, lakes, and oceans. It commonly contains less contamination than surface water because the rock tends to act as a filter to remove some contaminants. Ground Water is called as hard water due the presence of high mineral content.

A primary pollutant is an air pollutant emitted directly from a source.

A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.

these are harmful due to the fact that both are making the environment polluted and thus causing different disease like lung cancer, cholera, jaundice etc

The AQI measures five criteria air pollutants (particulate matter, sulfur dioxide, carbon monoxide, nitrogen dioxide, and ozone), and converts the measured pollutant concentrations in a community's air to a number on a scale of 0 to 500.
