Point Vs Non-point Source Pollution Notes Quiz

2.

True or false: Non-point source pollution is a larger problem than point source pollution.

True
False

Correct Answer

A. True

Explanation

Non-point source pollution refers to pollution that comes from multiple, diffuse sources, such as runoff from agricultural fields or urban areas. On the other hand, point source pollution comes from a single, identifiable source, such as a factory or wastewater treatment plant. The given answer, "True," suggests that non-point source pollution is a larger problem than point source pollution. This is because non-point source pollution is more widespread and harder to regulate and control compared to point source pollution, which can be more easily monitored and managed.

When the accumulation of rain flows over parking lots and roads in North Carolina, it washes pollutants into bodies of water. How is this pollution classified?

Primary
Secondary
Point source
Non-point source

Correct Answer

A. Non-point source

Explanation

When rainwater flows over parking lots and roads, it picks up pollutants such as oil, chemicals, and debris. This runoff is considered non-point source pollution because it does not come from a specific, identifiable source. Unlike point source pollution which comes from a single, identifiable source like a factory or sewage treatment plant, non-point source pollution is diffuse and comes from many different sources. It is challenging to control and manage non-point source pollution because it comes from various activities and areas, making it harder to regulate and mitigate its effects on bodies of water.

What is an example of point-source pollution?

Chemical runoff from roads
Beach trash that gets into the water
Sewage pipes draining into bodies of water
Fertilizer from lawns seeping into groundwater

Correct Answer

A. Sewage pipes draining into bodies of water

Explanation

Sewage pipes draining into bodies of water is an example of point-source pollution. This occurs when untreated or partially treated sewage is directly discharged into rivers, lakes, or oceans. It can lead to water contamination, harmful algal blooms, depletion of oxygen levels, and negative impacts on aquatic ecosystems. Sewage contains various pollutants, including bacteria, viruses, nutrients, and chemicals, which can pose a threat to both human health and the environment.

A landfill is most likely to directly pollute

Water vapor over the landfill
Precipitation about to fall on the landfill
Surface streams flowing to the landfill
Groundwater under the landfill

Correct Answer

A. Groundwater under the landfill

Explanation

A landfill is most likely to directly pollute groundwater under the landfill. Landfills are designed to contain waste materials, but they are not completely impermeable. As rainwater and other liquids seep through the landfill, they can pick up pollutants from the waste and contaminate the groundwater below. This polluted groundwater can then flow into nearby wells or surface water bodies, posing a risk to human health and the environment.
