mho - A unit of conductance. The conductance of a conductor in mhos is the reciprocal of its resistance in ohms.

micromhos per centimeter (µmho/cm) - 1/1,000,000 mhos per centimeter.

Milligrams per liter (mg/L) - means the quantity of material present in the water expressed on the basis of the weight (milligrams) per unit volume of solution (liter).

N - elemental Nitrogen

NTU (Nephelometric Turbity Unit) - Measure of the clarity of the water.

P - inorganic Phosphorus

pH Units - The acidity or alkalinity of the water expressed as negative common logarithm of the hydrogen-ion activity in moles per liter (< 7.0 acidic; > 7.0 alkaline).
