Turbidity is a measure of the suspended inorganic and organic particulate matter in the water. Turbidity measures how much the matter scatters and absorbs light.
	Turbidity is increased by increasing mineral concentration and plankton biomass in the water.
	Color: Measured by the amount of light scattered by organic and particulate matter in the water.
	Conductivity: The ability of water to conduct electrical current
	Dependent on the concentration and dissociation of dissolved ions in the water.
