The contamination of water bodies such as Seas, Ocean, Lake, Rivers, Ground Water etc is known as water pollution. Everyday, garbage such as plastic, paper, aluminum, food, glass, or rubber are deposited into the sea. Algae occur from an abundance of nutrients and (nitrogen and phosphorous) heat in the water. Unfortunately, water pollution is created when fertilizer, animal and human waste, plastics, and toxic industrial chemicals enter these sources. If the pollution comes from many sources, it is called nonpoint-source pollution. Collect the Water Pollution Analysis Data form with the turbidity and dissolved oxygen results. Here the student will get to know what are the main causes, effects and preventive measures to control water pollution.
