Temperature readings are used in the calculation of various forms of alkalinity, in studies of saturation and stability with respect to calcium carbonate, in the calculation of salinity, in a number of colorimetric tests, and in general laboratory operations. In limnological studies, knowledge of water temperatures as a function of depth often are required. Elevated temperatures resulting from discharges of heated water may have significant ecological impact. The source of water supply, such as deep wells, often can be identified by temperature measurements alone. Industrial plants often require data on water temperature for process use or heat-transmission calculations.
