[Solvents in drinking water from a thermostatic mixing battery].
In a hospital an odour of organic solvent could be smelled when a special thermostatic water mixer has been used. At no other water tap in the house a similar smell could be recognized. After stagnation overnight or after weekends the disgusting smell has been rather strong. The odour of organic solvent disappeared when the water had been running for some time. The organic compound in the drinking water has been identified and the thermostatic water mixer could be revealed as the source of the contamination. Further investigations of other thermostats showed a variety of alcoholic compounds which were used as thermostatic fluids.
