Study Notes
Types of Water Pollution
- Point-source pollution: pollution from a single, identifiable source (e.g. industrial waste, sewage)
- Non-point-source pollution: pollution from multiple, diffuse sources (e.g. agricultural runoff, urban stormwater)
Causes of Water Pollution
- Industrial activities: chemicals, heavy metals, and other pollutants from industrial processes
- Agricultural activities: fertilizers, pesticides, and manure from farming
- Sewage and wastewater: untreated or partially treated sewage from households and businesses
- Urban runoff: pollutants from urban areas, such as oil, grease, and heavy metals
- Mining activities: heavy metals and other pollutants from mining operations
Effects of Water Pollution
- Human health: exposure to pollutants can cause illness, disease, and even death
- Environmental damage: harm to aquatic ecosystems, loss of biodiversity, and disruption of food chains
- Economic impacts: costs associated with cleaning up pollution, loss of recreational and commercial uses of water
Common Water Pollutants
- Chemical pollutants: heavy metals, pesticides, fertilizers, and industrial chemicals
- Biological pollutants: bacteria, viruses, and other microorganisms from sewage and animal waste
- Physical pollutants: sediment, heat, and excess nutrients from human activities
Prevention and Mitigation Strategies
- Regulation and enforcement: laws and regulations to control pollution from industrial and agricultural activities
- Wastewater treatment: treating sewage and industrial waste to remove pollutants
- Best management practices: practices to reduce pollution from agricultural and urban activities
- Public education and awareness: educating individuals and communities about the importance of water conservation and pollution prevention
Types of Water Pollution
- Point-source pollution comes from a single, identifiable source, such as industrial waste or sewage.
- Non-point-source pollution comes from multiple, diffuse sources, such as agricultural runoff or urban stormwater.
Causes of Water Pollution
- Industrial activities release chemicals, heavy metals, and other pollutants into water.
- Agricultural activities introduce fertilizers, pesticides, and manure into water.
- Sewage and wastewater from households and businesses can pollute water if left untreated or partially treated.
- Urban runoff carries pollutants like oil, grease, and heavy metals from urban areas into water.
- Mining activities release heavy metals and other pollutants into water.
Effects of Water Pollution
- Exposure to pollutants can cause illness, disease, and even death in humans.
- Water pollution harms aquatic ecosystems, resulting in loss of biodiversity and disruption of food chains.
- Cleaning up pollution and losing recreational and commercial uses of water can be costly.
Common Water Pollutants
- Chemical pollutants include heavy metals, pesticides, fertilizers, and industrial chemicals.
- Biological pollutants include bacteria, viruses, and other microorganisms from sewage and animal waste.
- Physical pollutants include sediment, heat, and excess nutrients from human activities.
Prevention and Mitigation Strategies
- Regulations and laws can control pollution from industrial and agricultural activities.
- Wastewater treatment removes pollutants from sewage and industrial waste.
- Best management practices reduce pollution from agricultural and urban activities.
- Public education and awareness promote water conservation and pollution prevention.
pH of Water
- pH is a measure of the acidity or basicity of water, ranging from 0 to 14
- pH 7 is neutral, below 7 is acidic, and above 7 is basic
- Clean water typically has a pH between 6.5 and 8.5
- Polluted water can have a pH outside this range, indicating contamination or disturbance in the ecosystem
- Highly acidic water (pH < 4) can be harmful to aquatic life, while highly basic water (pH > 9) can also be toxic
