Water pollution affects both plants and animals and leads to a severe impact on the aquatic ecosystem. Our ocean and waterways are polluted with a wide variety of marine debris, ranging from tiny microplastics, smaller than 5 mm, to derelict fishing gear and abandoned vessels. Water is of fundamental importance for life on earth. Loading of contaminants to surface waters, groundwater, sediments, and drinking water occurs via two primary routes: (1) point-source pollution and (2) non-point-source pollution. This will ensure that all bacteria and other microbes are killed and will make the water safe for drinking, cooking and ice making. In the majority of cases this type is caused by rainfall or snow meltdown. ” 42 U. Although the merits of industrialization are innumerable, it has been identified as a major threat to the environment as it releases various toxic chemicals, gases, solid wastes as well as microbes of various kinds into our immediate environment—land, air, and water. Our ocean is being flooded with two main types of pollution: chemicals and trash. Definition. e. Water pollution occurs when pollutants (particles, chemicals, or substances that make water contaminated) are discharged directly or indirectly into water bodies without enough treatment to get rid of harmful compounds. Groundwater gets polluted when contaminants—from pesticides and fertilizers to waste leached from landfills and septic systems—make their way into an aquifer, rendering it unsafe for human use. Water systems maintain more than 2. , arsenic Leading Cause of Air Pollution. The wastewater and sewage that is produced by every home is treated with chemicals and then released into the sea.
