The measure of the amount of salt dissolved in water.

What is salinity?

100

Using living things to remove contaminants from water

What is bioremediation?

100

In this step, Wastewater undergoes a biological treatment process where micro-organisms break down organic matter.

What is step 2 in the wastewater treatment process?

100

You can test this using a thermometer.  A high result is a sign of poor water quality.

What is temperature?

100

These are the highest areas of land on Earth.

What are continental divides?

200

97% of the water on earth is of this type

What is salt water

200

Road salt is an example of this

What is a chemical contaminant?

200

In this step, Wastewater is disinfected with chlorine to kill harmful organisms.

What is step 4 in the wastewater treatment process?

200

You can test this by lowering a black and white disk into a water source.

What is turbidity?

200

These are the areas between the divides.

What are watersheds?

300

Grams/Litre

What unit of measurement is used for salinity

300

Wastes from animals, and parasites are examples of this.

What is a biological contaminant?

300

In this step, Wastewater is screened and moved into the grit tank.  It then moves to the settling tank for a few hours.

What is step 1 in the wastewater treatment process?

300

You can test this by using a pH test paper.

What is acidity?

300

There are 36 of these in Ontario.  They are organizations that manage and protect watersheds.

What is a Conservation Authority?

400

Salt is removed from salty water leaving fresh, drinkable water.

What is desalination?

400

This occurs when warm water is dumped into a river by factories.

What is thermal pollution?

400

In this step, Wastewater then moves to the clarifier where any remaining solids settle to the bottom.

What is step 3 in the wastewater treatment process?

400

This describes water that is very cloudy.

What is turbidity?

400

All of this from within a watershed leaves the watershed at the same exit.

What is runoff?

500

Only 3% of Earth's water is this type and most of it is frozen in glaciers and polar ice.

What is fresh water?

500

Salt, sediment, animal waste, fertilizers, and pesticides/herbicides can all enter a water source by this method.

What is runoff?

500

In this step, Solids from the settling tank and the clarifier are processed.

What is step 5 in the wastewater treatment process?

500

Conductivity apparatus can indicate the presence of this in  water.

What is salt?

500

This is an area surrounded by high land and drained by a river and its tributaries.

What is a watershed?
