Surface Thermocouple is a surface temperature sensor designed to reduce error in atmospheric applications where air currents cause instability in temperature accuracy. The surface thermocouple assembly includes thin layers of disparate noble metal compositions deposited on the reactive metal layer.

Surface treatment is a chemical or electrochemical treatment applied to the surface of a metal. Such treatments include pickling, etching, conversion coating, Phosphating, and chromating. Surface treatment baths are usually followed by a water rinse. The rinse may consist of single or multiple stage rinsing. For the purposes of this part, a surface treatment operation is defined as a bath followed by a rinse, regardless of the number of stages. Each surface treatment bath, rinse combination is entitled to discharge allowance

Surface water management includes a wide variety of activities that protect the natural functions and beneficial uses of surface waters. The main uses of surface water management include controlling erosion from construction sites, controlling the quantity & quality of storm water runoff from development, gathering & analyzing data through water quality monitoring & stream gauges, protecting & restoring fish habitat and comprehensive land use planning.
