Water pollution occurs when harmful substances from human activities enter bodies of water, making the water unpleasant and unsafe for drinking, swimming, and aquatic life. The main sources of water pollution are industries, agricultural lands, and homes. Polluted water can spread diseases, harm organs, accumulate toxins in the food chain, kill aquatic life, cause algal blooms, and threaten sea birds. To prevent further pollution, people should properly dispose of wastes, use fertilizers sparingly, avoid breaking water mains, clear drains, and quickly fix vehicle leaks.
WATER POLLUTION EVRS.pptx
Water pollution occurs when harmful substances are directly or indirectly discharged into water bodies without adequate treatment. There are two main sources of water pollution: point sources which discharge directly into water bodies like factories and power plants, and non-point sources which have no specific discharge location like runoff from agricultural fields and roads. Water pollution can have detrimental effects like encouraging algae growth which depletes oxygen levels, contaminating drinking water sources, and posing health risks to humans and aquatic life. Proper treatment of industrial effluents and domestic waste, public awareness, and established laws are needed to control water pollution.
Save rivers
River pollution occurs when chemicals, waste, and other pollutants are dumped into rivers from a variety of sources including industry, agriculture, and homes. Industry pollutes rivers through direct disposal of waste, toxic gas emissions that cause acid rain, and changes in water temperature from industrial runoff. Agriculture pollutes rivers when fertilizers and chemicals from farms are carried by rainwater runoff into waterways. Household trash and sewage systems can also introduce pollutants into rivers. River pollution has negative effects on wildlife, ecosystems, and human health. Prevention efforts include conserving soil, proper disposal of chemicals, cleaning up litter, reducing plastic use, and community involvement to address local polluters.

Prevention efforts include conserving soil, proper disposal of chemicals, cleaning up litter, avoiding plastic waste, and getting involved in monitoring local polluters.
Environmental pollution
Water pollution occurs when pollutants from human activities contaminate bodies of water. There are three main types of water pollution: physical, chemical, and biological. Physical pollution involves solid waste like plastics and garbage. Chemical pollution comes from fertilizers, oils, and sewage runoff from industrial plants and farms. Biological pollution involves disease-causing microorganisms. Other major causes of water pollution include oil spills, nutrient pollution from wastewater and fertilizers, disruption of food chains, and leaks from underground storage tanks. Water pollution destroys ecosystems, kills aquatic life, and poses health risks to humans who use contaminated water sources.

This document discusses water pollution, its causes, types, effects, and prevention methods. It defines water pollution as contamination of water bodies that makes water harmful to humans and aquatic life. The two main sources are point source pollution from specific locations like factories, and non-point source pollution from diffuse sources like agricultural runoff. Water pollution kills aquatic animals, disrupts food chains, spreads diseases, and destroys ecosystems. Prevention methods include proper waste disposal, reducing water and chemical usage, and wastewater treatment.
Water Pollution
This document discusses water pollution, including its causes, sources, types, effects, and methods of prevention. It defines water pollution as the contamination of water bodies by human and natural activities. The two main sources are point source pollution from single identifiable sources like factories, and non-point source pollution from multiple diffuse sources like agricultural runoff. Various types of water pollution are described, and effects include harm to aquatic life, disruption of food chains, diseases in humans, and destruction of ecosystems. Prevention methods center around proper waste disposal, reduced chemical usage, and wastewater treatment.
Water pollution
Water pollution occurs when harmful pollutants are discharged directly or indirectly into water bodies without adequate treatment. Pollution can come from point sources like oil spills or nonpoint sources like agricultural and residential runoff. Pollution can affect local areas or be transported long distances. Surface water pollution involves oceans, rivers and lakes and can result from oxygen depletion, nutrients, microbiological contaminants, suspended solids or chemicals from industry and agriculture. Groundwater can also be polluted from pesticides and other contaminants. While pollution harms aquatic life, simple individual actions like conserving water and properly disposing of household waste can help reduce pollution and protect water resources.
WATER POLLUTION.pptx
Water pollution arises from both natural causes and human activities that introduce dangerous chemicals and microbes into bodies of water. The main types of water pollution are pollution of oceans, surface water, and groundwater. Water pollution has negative effects on ecosystems by damaging plant and animal life and causing dead zones, and it also threatens human health by contaminating drinking water and making people sick. Key causes of water pollution include agriculture, industry, transportation accidents, and dumping of garbage. Prevention efforts include proper disposal of trash, chemicals, and spilled materials to keep pollutants out of waterways.
Water pollution
Water is essential for life on Earth but only a tiny fraction of water is available as freshwater for human use. While oceans hold 97% of the planet's water, only 0.003% is easily accessible as freshwater in lakes, rivers, soil and aquifers. Groundwater aquifers are an important source of freshwater but are vulnerable to pollution from agricultural, industrial and urban activities that can contaminate drinking water sources. Many forms of water pollution including disease-causing pathogens, oxygen-depleting wastes, excess nutrients, toxic chemicals, and radioactive substances threaten the limited freshwater resources and ecosystems upon which all life depends. Strategies are needed to protect this vital resource from overuse and pollution.

- 2. Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans , aquifers & groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.
- 3. Spread of disease: Drinking polluted water can cause cholera or typhoid infections, along with diarrhea. Affects body organs: The consumption of highly contaminated water can cause injury to the heart and kidneys. Harms the food chain: Toxins within water can harm aquatic organisms, thus breaking a link in the food chain. Causes algae in water: Urea, animal manure and vegetable peelings are food for algae. Algae grow according to how much waste is in a water source. Bacteria feed off the algae, decreasing the amount of oxygen in the water. The decreased oxygen causes harm to other organisms living in the water. Flooding: The erosion of soil into waterways causes flooding, especially with heavy rainfall. Harms animals: Birds that get into oil-contaminated water die from exposure to cold water and air due to feather damage. Other animals are affected when they eat dead fish in contaminated streams.
- 4. Disposal of waste: This waste includes sewage, garbage and liquid waste from factories and homes. Wastages from chemical factories contain many toxic or poisonous chemicals.. Chemical fertilizers and pesticides: Farmers use fertilizers for growth, and pesticides to kill insects that damage crops. Fertilizers and pesticides which are good for plants, may be harmful to human beings and animals.
- 5. Prevention of Water Pollution - - - - - - Pay and Pollute Prevention of Water Pollution - - - - - - don't Use too much Pesticides Prevention of Water Pollution - - - - - - Avoid Paint and Petroleum to Sinks
