Water Quality Parameters

pH

  • Measures acidic or basic quality of water
  • Controls many chemical and biochemical processes in water
  • Most aquatic organisms are adapted to a specific pH level and may die if the pH value changes slightly
What can change water pH?
  • Type of rocks and soils in the watershed
  • CO2 production and use
  • Acid rain, municipal and industrial discharges

 

Typical range for pH = 7.2 to 8.8
Indiana Stream Average = 8.0
State Standard = between 6.0 to 9.0
