Immediately after sampling, stabilize the water sample with 10 ml nitric acid (1.40 g/ml) per 1000 ml sample solution. 

The occurrence of zinc in drinking water is frequently a result of corrosion in galvanized water pipes. Soft water containing carbon dioxide, and also waters rich in chlorides and sulphates, pick up zinc from galvanized pipes particularly easily, gradually destroying the pipes in the process.
