Water Quality

What is salinity?

• The property of containing salt

• The amount of suspended solids

• Describes the condition of the water

• Describes how acidic or basic water is

What is dissolved oxygen?

• The property of containing salt

• The amount of suspended solids

• The measure of the amount of oxygen that is dissolved

• Describes how acidic or basic water is

Where are nitrates and phosphates found?

• Fertilizer

• Manure

• Detergent

• All of the above

Why are too many nutrients (like nitrates and phosphates) bad for our waters?

• Nutrients decrease the pH of the water, causing it to become increasingly acidic

• Nutrients change the salinity of the water

• Wetlands filter out runoff that may contain nutrients

• Nutrients in the water cause too much algae growth, which decrease the level of oxygen in the water

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 defines a macroinvertebrate?

• large enough to be seen without a microscope with no backbone (bugs)

• any bioindicator

• nitrates

• pH

High turbidity means.....

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

What is the end result of eutrophication?

• More algae
• decreased oxygen and fish kills
• less turbidity
• a new pond
