Calculated Langelier Saturation Index (LSI) Langelier Saturation Index, LSI = -0.46. If the LSI is: Negative: the water is corrosive (i.e., will tend to dissolve metals). 0.0: the water is neither corrosive nor scaling. Positive: the water is scaling (i.e., will tend to deposit calcium carbonate). The Langelier index (LI) is the difference between the actual (measured) pH and the calculated pH of water.
