What is water quality?

• It describes the condition of the water

• It is the continuous movement of water on, above, and below the surface of the Earth

• It is the property of containing salt

• It is the total amount of suspended solids.

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
