Basic Water Quality Measurements

The amount of oxygen in the water, measured in parts per million (ppm)

• pH
• Dissolved Oxygen
• nitrates
• eutrophication

High turbidity means.....

• very clear water
• neutral pH
• very murky or cloudy water
• high nitrates

If water temperature goes UP, what happens to the level of Dissolved oxygen?

• It goes up
• It goes down

Which water quality indicator will be most impacted by burning fossil fuels and air pollution?

• nitrates
• pH (water will be more acidic)
• Dissolved oxygen
• turbidity

Describes the chemical, physical and biological attributes of water as it is fit for drinking, fishing, swimming, farming, etc

• Water Quality
• Water Sheds
• Dissolved oxygen
• nitrates

We used bioindicators to measure the quality of water.  What is a bioindicator?

• any living creature
• eutrophication
• An organism sensitive to its environment
• a turbidity tube

What is salinity?

• The property of containing salt

• Describes the condition of the water

• The amount of suspended solids

• Describes how acidic or basic water is

What is pH?

• The property of containing salt

• The measure of the amount of oxygen that is dissolved in water

• The amount of suspended solids in water

• The measurement of the acidity or basicity of water

pH value of less than 7 is considered to be

• polluted.

• basic.

• like drain cleaner.

• acidic.

pH greater than 7 is considered to be

• neutral.

• basic.

• acidic.

• polluted.
