Front

What is a point source of pollution?

Back

A point source of pollution is a single, identifiable source of pollution, such as a factory smokestack or a sewage discharge pipe.

Front

What is a nonpoint source of pollution?

Back

A nonpoint source of pollution is diffuse and does not have a single point of origin, such as runoff from agricultural fields or urban areas.

Front

What is biological oxygen demand (BOD)?

Back

Biological oxygen demand (BOD) is a measure of the amount of oxygen that microorganisms will consume while decomposing organic matter in water.

Front

What is dissolved oxygen (DO)?

Back

Dissolved oxygen (DO) is the amount of oxygen that is present in water, which is essential for aquatic life.

Front

What is the significance of preserving wetland habitats?

Back

Preserving wetland habitats helps to protect against flooding, filter pollutants, and provide habitat for wildlife.

Front

What is the largest component of municipal solid waste in the US?

Back

The largest component of municipal solid waste in the US is paper.

Front

What health risks are associated with lead exposure?

Back

Exposure to high concentrations of lead can cause kidney and brain damage.

Front

How does urban runoff contribute to water pollution?

Back

Urban runoff can carry pollutants such as oil, heavy metals, and nutrients into water bodies, leading to water quality degradation.

Front

What role do mangroves play in coastal ecosystems?

Back

Mangroves provide critical habitat for marine life, protect shorelines from erosion, and act as natural water filters.

Front

What is the impact of excess organic matter on a stream's oxygen levels?

Back

Excess organic matter can lead to increased biological oxygen demand (BOD), resulting in lower dissolved oxygen (DO) levels, which can harm aquatic life.
