Fe, Cr, Cu, Ni and Mn Concentration Determination from Matatilla Water System by Atomic Absorption Spectroscopy

Konjengbam Dayananda Singh


This study was conducted to assess the extent of heavy metal in the Matatilla Dam water systems. Water quality is effect by the many substance water contacts during its movement through the hydrological system. Water dissolves a wide variety of minerals, nutrients and other substance from soils, rocks and atmosphere carries them in water system. Lake streams and ground water accumulate these dissolve substance and reflect distinctive characteristic of this watersheds, soils and geology land used. Human activities also can change the composition of surface runoff and ground water. Water is vulnerable to contamination at all points in the hydrological cycle, and all pathways that transport water can also carry pollutants. A total of 10 monitoring stations were established along the dam water system, and water is collected from that sampling sites. Atomic absorption spectroscopy techniques were employed for the determination of heavy metal in water samples. Elemental concentration of Fe, Cr, Cu, Ni and Mn were measured. The trends of heavy metal in water of Matatilla water system are Fe, Mn, Cu, Cr and Ni. In concordance with these results and with international standards of water quality can established that Matatilla water system is second class surface water (medium clean fresh water resources used for consumption but passing an ordinary treatment process before used for agriculture).
