Water Quality

Color

• Every day water you see contains dissolved minerals or suspended materials.
• an example of dissolved substances tannin.
• tannin is caused by organic matter
• Soil runoff produces variety of yellow,red,brown and gray colors.
• Water rich in phytoplankton and other algae usually appears green.

Dissolved oxygen

• You cant tell how much oxygen is in the water by looking at it.
• Rapidly moving water contains lots of oxygen.
• The dissolved oxygen is breathed by fish.
• Water at the bottom does not have enough oxygen for fish to survive.

PH

• Ph is the measure of how acidic/base water is.
• The range goes from 0-14
• 7 is nutral
• Less than 7 is acidity
• Greater that 7 is a base.

Turbidity

• is the measure of relative clarity of a liquid.
• The higher the intensity of scattered light,the higher the turbidity.
• Turbidity makes the water cloudy or opaque.

Sediment

• Sediment in rivers can also shorten the lifespan of dams and reservoirs.
• Rocks as small as tiny clay particles and as large as boulders moved by the water are called sediment.
• Sediment can make the river muddy.

Hardness

• The amount of calcium and magnesium determines its hardness.
• Hard water can damage equipment
• water hardness varies throughout the united states.
• Hard water can damage fabrics.

Temperature

• The temperature can determine the organisms that live in the water.
• If there are more chemical reactions then the temperature will most likely be higher.
• The aqua life don't get concerned about the water unless it is changed by human then they start to worry.
