Water Review February 2021

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 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 end result of eutrophication?

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

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
