Industrial waste can be defined as waste generated from industrial factories, especially through manufacturing or industrial processes. There are different types of industrial wastes, some of them can be considered as hazardous wastes like cleaning fluids, paints or pesticides discarded by commercial establishments which can contain dangerous chemical substances. These industrial wastes can be extremely toxic and can pose a dangerous threat to public health and the environment. 

Water is the spring of life. Every animal and plant is on this planet, surviving due to the blessing of water. Safe water is crucial for a healthy ecosystem and livelihood. Even though 71% of the earth’s surface is covered with water, water that is suitable for drinking and safe usage is very scarce as there are limited fresh water sources. But even these limited water sources are under threat from the pollution resulting from industrial wastes. Toxic industrial discharges seriously affect the water quality.

Some physical indicators of water pollution caused by chemical discharges can be the following-

• Sharp chemical odors (similar to petrol)

• Discoloration of water

• Foaming on water surface

• Multicolored sheen on the water 

• Increasing filth and dirt and pollution results into death of fishes and aquatic life. Accumulation of solid wastes, chemicals cause mass destruction of aquatic life. 

• Reduced oxygen level in rivers, making it biologically dead. It causes extinction of indigenous organisms.
