Chlorine is a naturally-occurring chemical element. Although it occurs naturally on earth, it exists chiefly in compounds, bound to other types of atoms such as sodium. Chlorine is highly reactive, so it bonds easily with other elements. More than 2,000 naturally-occurring chlorine-based compounds have been identified in all kinds of organisms. Example: If a chlorine gas concentration of 15 ppm were added to a storage tank holding 2.5 MG, how many lbs of chlorine would be needed? (Gas) lbs = (Vol, MG) x (Dosage, mgl) x (8.34 lbs/gal) Chlorination -box 2 2.

Since there are so many types, many of us in the industry just refer to all of these compounds and DBPs as chloramines. Combined chlorine is measured by subtracting free available chlorine from the total available chlorine. The equation looks like this
