Study Notes
Water Pollution Definition
- Water pollution occurs when non-water substances are introduced into water, causing potential imbalance and damage to the environment.
- Polluted water is unusable for drinking, human use, irrigation, and livestock.
- Main water pollutants include bacteria, viruses, parasites, fertilizers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, fecal waste, and radioactive substances.
Sources of Water Pollution
- Sources of pollution can be categorized into two: point sources and non-point sources.
- Point sources: pollution occurs from a single, identifiable source (e.g., oil spill, pipe discharging wastewater).
- Non-point sources: pollution occurs over a wide area with many possible sources (e.g., town, industries, agricultural area).
Classification of Water Pollution
- Water pollution can be classified into two categories: natural and anthropogenic.
- Natural pollution: caused by natural phenomena or natural processes (e.g., animal decomposition, volcanic eruption).
- Anthropogenic pollution: caused by human activities (e.g., hospital wastewater, industrial waste).
Types of Water Pollution
- Water pollution can be classified into surface water pollution and groundwater pollution.
- Surface water pollution: alteration of surface water bodies through harmful substances (e.g., rivers, lakes, seas).
- Groundwater pollution: introduction of substances that alter the original composition of groundwater.
Surface Water Pollution
- Surface water pollution is easier to detect and remedy due to accessibility.
- Anthropogenic sources of surface water pollution include domestic wastewater, industry wastewater, livestock wastewater, and agricultural wastewater.
- Pollutants in surface water include organic matter, pathogens, heavy metals, pharmaceuticals, hydrocarbons, and nutrients.
- Effects of surface water pollution include a decrease in dissolved oxygen, increased turbidity, sedimentation, eutrophication, and expansion of pathogen bacteria.
Groundwater Pollution
- Groundwater pollution is more difficult to detect and remedy due to inaccessibility.
- Groundwater pollution can be direct or diffuse, depending on the characteristics of the terrain.
- Characteristics of groundwater pollution include diverse origin and distribution of pollutants, localized or widespread contamination, and slow movement of groundwater.
- Risks of groundwater pollution are similar to those of surface water, except for eutrophication.
