Major Categories of Pollutants

Point Sources: Direct, identifiable discharge pipes from factories, wastewater treatment plants, and sewer systems.
Non-Point Sources: Diffuse runoff from agricultural fields carrying fertilizers, urban streets bearing oil, and mining areas.
Organic Wastes: Sewage and animal manure that deplete Dissolved Oxygen (DO) levels, raising Biochemical Oxygen Demand (BOD).
Chemical Contaminants: Heavy metals (lead, mercury), synthetic pesticides, pharmaceuticals, and industrial plastics.

Ecological Consequences

Eutrophication: Nutrient overloading triggers massive algal blooms, blocking sunlight and creating aquatic “dead zones.”
Bioaccumulation: Toxins build up inside aquatic organisms and intensify as they move up the food chain.
Habitat Destruction: Sedimentation blankets riverbeds, destroying spawning grounds for fish and macroinvertebrates.

Modern Solution Frameworks

Phytoremediation: Utilizing specific aquatic plants to naturally absorb and break down heavy metals and excess nutrients.
Riparian Buffers: Planting vegetation strips along riverbanks to filter agricultural runoff before it reaches open water.
Effluent Treatment: Enforcing multi-stage industrial wastewater processing (primary, secondary, and tertiary treatments).
