Bio-Indicators

a measure of the cloudiness of a substance

• turbidity

• cloudy with a chance of meatballs

• NTU

• hydrocloudiology

the results of turbidity are

• temperature increase caused

  by increase of sunlight absorption;

  darker water holds more heat

• water that is crystal clear

• water that precipitates as it condenses

• dirty rain

levels on the pH scale range from

• Close to neutral (7). Levels range from

  1 to 14 with acids at the lower

  numbers and bases higher

• the measure of acidity

  acid example: lemon juice

  base example: baking soda

• 15-22

• natural conditions (especially in

  swamps) dumping waste and farm

  runoff

what can cause a change in pH?

• natural conditions (especially in

  swamps) dumping waste and farm

  runoff

• turbulent water, depth, and

  plant growth

• High levels of variety = healthy aquatic

  ecosystem

• increased levels of phytoplankton,

  sediment, erosion, water algae
