Nutrients can be used to supplement freshwater. If done, aquatic plants show an abnormal increase in growth and this artificial process is eutrophication. Excess nutrients in water cause damage. The body of water will be choked with organic matter. And the microorganisms in the water are overpowered by the organic matter, which causes the rapid growth of algae. This adds more to the organic waste already present in the water. Dissolved oxygen is completely depleted from the water. As a result, ‘anaerobic’ organisms seize organic waste and release methane gas and hydrogen sulfide. These gases are harmful to aerobic lifestyles. Aerobic forms need oxygen to survive. The body of water produces a foul odor and causes suffocation. The stench that spreads throughout the region reminds us of our citizens and civic responsibilities. Individuals feel helpless, but a collective effort can and will produce some results.
Intensive use of chemicals and fertilizers, especially nitrates and pesticides, by farmers causes groundwater pollution. Unaware of this leaching process, farmers continue to contribute to the pollution of our groundwater.
Indiscriminate disposal of domestic and industrial wastewater adds insult to injury. Chemical compounds are abundant in industrial wastewater. These are easily identifiable. So are toxic wastes and organic pollutants. The food products industries and chemical industries have a large share in misusing the water body and denying a healthy normal life for humanity.
Industrial rich treatment facilities should be sufficient and should be made compulsory. Authorities, especially Leather processing industries, Sugar factories, Distillates, Thermal power plants etc. should regularly inspect such industries. Some of the major industries have shown great interest in solving the pollution crisis. The positive responses are quite encouraging. Unfortunately, most small-scale industries can’t afford to do anything about pollution control.
