Water Chemistry
Dissolved Oxygen ____________ ppm Turbidity
___________ NTUs
Temperature Temperature determines the rate of chemical and
metabolic reactions in fish and other organisms. Warm water speeds up reactions, therefore, warm water usually
contains more fish that grow bigger and faster. However, warm water holds less oxygen, so some organisms might
die if the water gets too warm.
pH Fish, frogs, and most other aquatic life can
tolerate a pH of 5 to 8.5 (neutral pH =
7.0;
pH < 7.0 is acidic and pH > 7.0 is alkaline or
basic.) The pH of rain is naturally
5.5 Causes of increased acidity of
water include: acid rain and industrial
wastes.
Dissolved
Oxygen (DO) Oxygen is essential for
aquatic organisms. Lack of oxygen in the water can cause many stream insects
and fish to die. Dead plants and animals or human wastes in the water require
oxygen to break down and decompose. Too
much of these wastes may use up all of the oxygen dissolved in the water. Dissolved oxygen (DO) concentrations should
not be less than 4.0 ppm for warm water fish and not less than 5.0 ppm for cold
water fish. Cold water can hold more DO than warm water.
Turbidity Turbidity, or cloudiness in
the water, is caused by soil particles eroding into the water, or lots of
microscopic plankton due to to much nutrients in the water. Soil erosion can bury fish eggs and other
larval insects living on the bottom of the pond, damage gills, block sunlight,
and interfere with the ability of fish to find food. Drinking water < 0.5 NTU; groundwater < 1.0 NTU.
