Swim Water Quality - Algae and Bacteria

The video discusses the importance of water safety, focusing on swim advisories due to poor water quality caused by bacteria and harmful algal blooms. It explains how algal blooms deplete oxygen, affecting ecosystems and human health. The video also highlights the role of human activities in exacerbating these issues and provides practical solutions to reduce runoff and improve water quality.

What are the two main issues that can lead to swim advisories?

• Cold water temperatures and strong currents

• Too many swimmers and high tides

• Excessive salt and sand in the water

• High levels of bacteria and harmful algal blooms

What is an algal bloom?

• A flower that blooms in water

• A rapid increase in algae that can be harmful

• A type of seaweed that grows on rocks

• A type of fish that feeds on algae

How do algal blooms affect marine life?

• They increase the water temperature

• They clean the water by filtering impurities

• They block sunlight and deplete oxygen

• They provide extra food for fish

What is a common source of bacteria in water?

• High salt content

• Runoff carrying fecal matter

• Excessive sunlight

• Cold water temperatures

What is one of the most extreme types of bacteria found in water?

• Algae-eating bacteria

• Salt-resistant bacteria

• Heat-loving bacteria

• Flesh-eating bacteria

Which of the following is a way to reduce runoff and improve water quality?

• Using more fertilizers

• Using low phosphorus soaps

• Washing cars on paved driveways

• Increasing pavement on properties

What should you do if you see many dead fish along the shoreline?

• Collect them for research

• Feed them to other animals

• Ignore it and continue swimming

• Report it to your community
