Lake water quality assessment using spatial interpolation and the development of the WQI on an educational campus, Assam, India

Abstract Monitoring water quality metrics is essential for managing and safeguarding aquatic life. The NIT Silchar Lake has been a place survival many plants migratory birds. lake typically used on campus horticultural purposes. However, the peasants living close to use drinking during situations like floods or famine. At four separate locations of lake, samples were collected evaluation seven indicators. circumstances life determined be favourable, with temperatures between 22.4 30.5 °C dissolved oxygen levels 8 13 mg/l, respectively. measured values (six parameters) combined create index (WQI), which unifies parameters into single number indicate overall status quality. regions that ranged from good excellent identified using ‘weighted arithmetic index’ technique. Further we have compared another method. A comparative analysis done by developing simple codes help python programming language. IDW (Inverse Distance Weighted) interpolation method in GIS was applied spatial distribution WQI.
