Water Pollution Definition

Water pollution occurs when substances or elements are introduced into water, causing imbalance and harm to the environment and ecosystem.
Polluted water is unusable for drinking, agriculture, and livestock.

Sources of Water Pollution

Point sources: single, identifiable source of pollution, e.g., oil spill or wastewater discharge into a river.
Non-point sources: pollution from a wide area with many possible sources, e.g., pollution from a town or agricultural area.

Classification of Water Pollution

Natural: pollution caused by natural phenomena or natural processes, e.g., animal corpse decomposition or volcanic eruption.
Anthropogenic: pollution caused by human activities, e.g., hospital wastewater discharge into a river.

Types of Water Pollution

Surface water pollution: alteration of surface water bodies, e.g., rivers, lakes, and oceans, through harmful substances.
Groundwater pollution: introduction of substances that alter the composition of groundwater, compromising its quality.

Surface Water Pollution

Examples of surface water bodies: rivers, creeks, lakes, ponds, seas, and oceans.
Anthropogenic sources: domestic wastewater, industry wastewater, livestock wastewater, and agricultural wastewater.
Pollutants: organic matter, pathogens, heavy metals, pharmaceuticals, hydrocarbons, and nutrients.
Effects of pollution: decrease in dissolved oxygen, increased turbidity, sedimentation, eutrophication, and expansion of pathogen bacteria.

Groundwater Pollution

Introduction of substances that alter the original composition of groundwater, compromising its quality.
Accessibility to groundwater is difficult, making pollution harder to detect.
Characteristics: diverse origin of pollutants, high spectrum of distribution, and localized or widespread contamination.
Risks: similar to surface water pollution, except for eutrophication due to lack of sunlight.
