Examples of Water Pollutants and Their Sources in Your Community

📚 Quick Study Guide

• 🌊 Water Pollutants: Substances that contaminate water sources like rivers, lakes, and groundwater.
• 🏭 Point Source Pollution: Pollution from a single, identifiable source (e.g., factory discharge pipe).
• 🌱 Non-Point Source Pollution: Pollution from diffuse sources (e.g., agricultural runoff).
• 🧪 Common Pollutants: Include chemicals, pathogens, nutrients, and heavy metals.
• 🍎 Nutrient Pollution: Excess nitrogen and phosphorus can cause algal blooms.
• 🦠 Pathogens: Bacteria and viruses that can cause diseases.
• ⚖️ Regulation: Laws like the Clean Water Act aim to reduce water pollution.
