APES Unit 8 Exam Review

Front

What is the impact of sewage overflow on water quality?

Back

Sewage overflow leads to low dissolved oxygen (DO), high biochemical oxygen demand (BOD), and high fecal coliform levels.

Front

What legislation mandates the protection of the nation's waters?

Back

The Clean Water Act mandates maintaining the integrity of the nation's waters.

Front

Which water quality test measures the clarity of water and can indicate disruption of photosynthesis?

Back

Turbidity is the water quality test that best determines the disruption of photosynthesis caused by cloudy water conditions from sedimentation.

Front

What pollutant is mitigated by electrostatic precipitators?

Back

Electrostatic precipitators are used to mitigate PM2.5 (particulate matter less than 2.5 micrometers in diameter).

Front

When does smoke from forest fires affect air quality over larger areas?

Back

Smoke from forest fires affects air quality over larger areas for many days when a persistent atmospheric inversion exists in the region.

Front

What is Biochemical Oxygen Demand (BOD)?

Back

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) and why is it important?

Back

Dissolved Oxygen (DO) is the amount of oxygen available in water, essential for the survival of aquatic organisms.

Front

What is Turbidity and how does it affect aquatic life?

Back

Turbidity refers to the cloudiness of water caused by suspended particles, which can inhibit photosynthesis and harm aquatic ecosystems.

Front

What is the Clean Drinking Water Act?

Back

The Clean Drinking Water Act establishes standards for drinking water quality to protect public health.

Front

What is Acid Deposition?

Back

Acid deposition refers to the falling of acids from the atmosphere to the ground, often as rain, snow, or dust, which can harm ecosystems.
