Unit Definitions

cfs stands for cubic feet per second. 1 cfs equals about 7.5 gallons per second.

°C stands for degrees Celsius, which is the metric system's unit for temperature. 0°C is the freezing point of water, and 100°C is the boiling point.

mg/l means "milligrams per liter". In the metric system, one liter of water weights 1,000,000 mg, so this measurement is the same as saying "parts per million".

µS/cm means "micro siemens per centimeter". A "siemen" is a measure of electrical conductivity, so the unit indicates how well the water conducts electricity through a centimeter of water.

NTU stands for "nephelometric turbidity unit" and is a measure of how cloudy, or turbid, the water is. The lower the number the clearer the water.
