Water – Water content found in the system. This may be a freshwater source e.g. tap water, or saline water (with sodium), or coolant (with sodium and/or potassium and possibly glycol / antifreeze). In water based fluids, the water content needs to be within certain concentrations to maintain fire-resistance properties. If water is a contaminant in the system then it needs to be prevented from entering or removed after ingress (see Section on symptoms and corrective actions for details on how).
Glycol – this is an analysis linked to the water content. Glycol contamination suggests a coolant leak, incorrect sampling or use of a dirty top-up can.
