What is Wastewater?

• wastewater it water that has been touched by humans

• wastewater is water that is flushed down the toilet and sent through pipes in the ocean

• wastewater is water that has already been used or water that has been polluted, and is non-drinkable water

• wastewater is water that people can drink and not die from

Is it better to have a bio-indicator in a narrow range or a wide range of conditions?

• a narrow range because the range of water quality you can find is more specific so less testing is necessary

• a wide range because it lets people test the water more so that they know it is really clean

How does the temperature affect bio-indicators?

• The temperature can freeze or fry the animals and life in the water that the bio-indicators are in

• Many bio-indicators will die if the temperature is really high, certain animals and life won't be able to survive if they are used to cooler temperatures.

• Many bio-indicators will die because of fast changes in the temperature that are too bad for other wildlife

• Certain organisms can only live in a certain range of water temperature. If the temperature changes quickly, there will be more/less of certain animals that need a certain temperature range.

What is a bio-indicator?

• robots that spy on the water

• an organism that will only live in a specific environment

• animals that live in water

• an organism that dies if its not in the correct environment

Which is the best description of the best water quality you could have?

• high temperatures = low turbidity with higher dissolved oxygen

• cool temperatures = high turbidity with lower dissolved oxygen

• cool temperatures = low turbidity with higher dissolved oxygen

• high temperatures = high turbidity with lower dissolved oxygen

What is eutrophication?

• when there is an excess amount of nitrates in water so there is an algal bloom, so plants die because of the lack of oxygen

• when there is too much oxygen that the plants grow too much

• when people dump too much garbage into the waters and the garbage kills plants

• when there is not enough nitrates, in water so there is plant growth, so plants grow and there is too much oxygen

Why does the water quality matter?

• if people litter and breath too much air the water gets polluted

• if there is too much trash we die

• when the water quality is healthy for us but when its not it creates illness and can cost lives because of the pollution in the water.

What is water stewardship?

• when people blame other people for the quality of their water

• when people take responsibility for their water, like taking the trash out, and not throwing garbage/trash into the water

• when people blame the government for their water being horrible

What are ways of "treating" water to make it fit for human consumption?

• giving the water to a plant so people can drink it

• giving the water to homeless people (just an example)

• by filtering it with something like a life straw, or have it be filtered by a plant that cleans the water with chemicals
