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

• pH
• Dissolved Oxygen
• nitrates
• eutrophication

Bioindicators measure the quality of water. What is a bioindicator?

• any living creature

• eutrophication

• An organism sensitive to its environment

• a turbidity tube

The specific bioindicator we used were macroinvertebrates.  What is a macroinvertebrate?

• large enough to be seen without a microscope with no backbone (bugs)
• any bioindicator
• nitrates
• pH

What is the healthiest combination listed?

• low pH, high nitrates, neutral temperature
• low temperature, neutral pH and low nitrates
• as many nitrates as possible, low temp and low pH
• high temp, high nitrates and high pH

High turbidity means.....

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

what is the biggest impact of run-off in urban areas on stream health?

• incised, steep banks and a narrow stream channel due to erosion
• high turbidity
• high nitrates due to fertilizer
• sewage leaks

What is the end result of eutrophication?

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