Because it is more difficult to access
What is the main difference between direct and diffuse pollution of groundwater?
Direct pollution occurs through direct entry into the subsoil, while diffuse pollution occurs through the natural recharge of the aquifer
What is a characteristic of groundwater that makes it difficult to prevent or eliminate contamination?
It moves very slowly and responds with great inertia to external actions

Eutrophication
What is the primary way to classify the sources of water pollution?
By the activity or entity responsible for the pollution
What is an example of natural pollution?
An animal's corpse decomposing in a lake
What is a consequence of eutrophication in a water body?
An overgrowth of algae that blocks sunlight
What is a result of surface water pollution that affects humans?
Alteration of the water's smell and taste
What is the state of the environment in its natural state?
In balance
What can contaminated water bodies become due to pollution?
Useless
What is the purpose of identifying the sources of water pollution?
To solve the problem of water pollution
What is characteristic of non-point sources of water pollution?
They occur over a wide area with many possible sources
What can be used to determine the status of water quality?
Chemical analysis of small samples of water and aquatic organisms
What is the main reason why groundwater pollution is difficult to fix?
Because of the inertia of groundwater movement
What is a factor that affects the level of contamination of groundwater?
The type of soil the water passes through
What is a source of direct pollution of groundwater?
Septic tanks used to treat wastewater
What is the primary source of water for human activities?
Surface water and groundwater
Why is groundwater pollution a concern for all forms of life?
Because it can affect the entire food chain
How does the terrain affect the movement of groundwater?
It slows down the movement of groundwater
What is the result of the decomposition of an animal's corpse in a body of water?
Introduction of bacteria to the water
What is the effect of rainwater runoff on surface water bodies?
Carries pollutants and affects the composition of water
What is the purpose of testing water samples for fecal coliform bacteria?
To conclude if the water is polluted or not
Why is it difficult to use polluted water for human activities?
Because of its altered smell, taste, and color
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.
