Total organic carbon, mg/L

If this parameter is below 0.5 mg/L, biofouling is unlikely. Above 2 mg/L, biofouling is very likely.

UV₂₅₄, cm^-1

If this value is below 0.5 cm^-1, the saline source water has low potential for organic fouling and biofouling.

Specific UV absorbance

If this is greater than 4, the source water is dominated by aquatic humic matter and biofouling is unlikely. If it is less than 2, the source water is experiencing algal bloom and biofouling is likely.
