Water Quality Booklet

Point & Non-point Source Pollution

pH

Temperature

Dissolved Oxygen

Phosphates

& Nitrates

Bio-indicators

Turbidity

(Color, Sediments & Hardness)

Slide3

Point & Non-point Source Pollution

Create a Venn diagram that compares and differentiates between point and nonpoint source pollutions. Make sure your Venn has

2

similarities and at least 4 differences on each side.

Slide4

pH

What is it?

Why is it important?

Acceptable level/conditions

What causes water to become too acidic? Why?

What causes water to become too basic (alkaline)? Why?

How does the pH level of a body of water influence what organisms live there?

Slide5

Temperature

What is it?

Why is it important?

Acceptable level/conditions

Explain 3 other indicators that are affected by temperature.

Why is colder water generally better for aquatic life?

Slide6

Dissolved Oxygen

What is it?

Why is it important?

Acceptable level/conditions

Does cold water hold more or less dissolved oxygen? Is this good or bad? Explain.

What 3 factors can influence dissolved oxygen levels?

Slide7

Phosphates & Nitrates

What is it?

Why is it important?

Acceptable level/conditions

Slide8

Bio-indicators

What is it?

Why is it important?

Acceptable level/conditions

Give 3 examples of bio-indicators and explain how each one tells us about the health of the environment.

Slide9

TurbidityColor, Sediments & Hardness

What is it?

Why is it important?

Acceptable level/conditions

What are 2 causes of increased turbidity?

Explain how dissolved oxygen decreases with increased turbidity.

Draw a diagram of 3 samples of water with different turbidities.
