Water pollution isA. Addition of undesirable substances into water bod...
Water pollution is the addition of undesirable substances into water bodies. It can result from various sources such as industrial waste, agricultural runoff, and sewage discharge. The contaminants introduced into the water can have harmful effects on the environment and human health.
In conclusion, water pollution is the addition of undesirable substances into water bodies, which can have detrimental effects on the environment, aquatic life, and human health. It is crucial to take preventive measures and implement proper waste management practices to minimize water pollution and protect our water resources.

Causes of Water Pollution:
- Industrial Waste: Discharge of chemicals, heavy metals, and toxins from industries can contaminate water bodies.
- Agricultural Runoff: Pesticides, fertilizers, and animal waste from agricultural activities can enter water sources, causing pollution.
- Sewage Discharge: Improperly treated or untreated sewage can release pathogens and pollutants into water bodies.
- Oil Spills: Accidental release of oil into water bodies can have catastrophic effects on aquatic life.
- Urban Runoff: Stormwater runoff from urban areas can carry pollutants like oil, heavy metals, and trash into water bodies.
- Improper Waste Disposal: Dumping of waste materials, including plastics and chemicals, into water sources contributes to pollution.
Effects of Water Pollution:
- Ecological Damage: Water pollution can harm aquatic ecosystems, leading to the decline of fish and other aquatic species.
- Human Health Risks: Contaminated water can cause waterborne diseases, including diarrhea, cholera, and dysentery.
- Loss of Biodiversity: Pollution can disrupt the balance of aquatic ecosystems, resulting in the loss of biodiversity.
- Economic Impact: Water pollution can negatively affect industries such as fishing, tourism, and agriculture, leading to economic losses.
- Drinking Water Contamination: Polluted water sources can contaminate drinking water supplies, posing a risk to human health.
Prevention and Control of Water Pollution:
- Treatment of Industrial Wastewater: Industries should implement proper treatment processes to remove pollutants from their wastewater before discharging it into water bodies.
- Proper Waste Disposal: Waste materials should be disposed of correctly, following regulations and guidelines to prevent pollution.
- Agricultural Best Practices: Farmers can adopt sustainable agricultural practices to minimize the use of pesticides and fertilizers, reducing agricultural runoff.
- Sewage Treatment: Proper treatment of sewage is essential to remove harmful pathogens and pollutants before releasing it into water bodies.
- Environmental Education and Awareness: Spreading awareness about the importance of clean water and promoting responsible water usage can help prevent water pollution.
- Regulatory Measures: Governments should enforce strict regulations and policies to control pollution sources and ensure compliance with environmental standards.
In conclusion, water pollution is the addition of undesirable substances into water bodies, which can have detrimental effects on the environment, aquatic life, and human health. It is crucial to take preventive measures and implement proper waste management practices to minimize water pollution and protect our water resources.

Understanding Water Pollution
Water pollution refers to the contamination of water bodies such as rivers, lakes, oceans, and groundwater. It is primarily caused by human activities that introduce harmful substances into these ecosystems.
Key Aspects of Water Pollution
- Addition of Undesirable Substances
- This is the most direct definition of water pollution. It involves introducing harmful chemicals, waste, or pathogens into water bodies, leading to degradation of water quality.
- Removal of Desirable Substances
- While this aspect is less commonly discussed, removing essential nutrients and minerals from water can also lead to pollution. For example, the removal of oxygen in water due to excessive algal blooms can harm aquatic life.
- Change of Temperature
- This refers to thermal pollution, which occurs when industries discharge heated water into natural water bodies. This temperature change can disrupt aquatic ecosystems and affect species survival.
- Addition of Desirable Substances
- Although adding beneficial substances can be seen as improving water quality (e.g., nutrients for plants), if done excessively or inappropriately, it can lead to problems like eutrophication.
Conclusion
The correct answer to the question about water pollution is option 'C', which states that all provided choices (a, b, and c) are correct. Each point highlights different dimensions of how water quality can be compromised, either through harmful additions or detrimental changes to the water's environment. Understanding these concepts is crucial for effective water management and pollution prevention strategies.
