What is an example of a point source of pollution?
A pipe spilling chemicals from a factory into a river is an example of a point source of pollution. Drip irrigation can reduce the amount of water used on a farm. The addition of any substance to water that has a negative effect of living things is called recycling.
What are the main causes of water pollution?
| | |. Chemical runoff is a major source of water pollution. It occurs when there is more water than land can absorb. In extreme cases, the excess flow of liquid can cause irreversible damage to everything in its path.
What are the main sources of nutrient and sediment pollution?
While these activities are the dominate sources of nutrient and sediment pollution, other agricultural activities – such as banana, horticulture and grains production – as well as intensive land uses that have point source emissions – such as sewage treatment plants, aquaculture and mining activities – also contribute to poor reef water quality.
What are the direct and indirect sources of water pollution?
The direct sources include outfall from factories, waste treatment, plants, refineries, etc... then, indirect sources are contaminants that enter the water such as, runoff from farmlands and acid rain from the atmosphere.
