Zoning and qualitative analysis of drinking water in the villages around the Urmia lake

From The biological aspects consumption of water containing Soluble salts and harmful metals that amount of it determined by total disolved solids (TDS) and the electrical conductivity (EC) affects the Cellular metabolism of the body s cells [1]. All societies need water and can not live without it. Surface waters, are not suitable for drinking becaese they are not clear and generally havent suitable pH, contain different organic materials Contaminated with microorganisms Ammonia, phenol, nitrate and phosphate. Groundwater Usually have Low suspended solids, very low organic materials pH (6.9-7.9) and may have sand. Microorganisms usually are absent in deep wells and may present in Semi-deep wells [2]. The number of water wells used for drinking In terms of water type, facies, Water Quality Index, and The other usual physicochemical parameters examined. And some typical results showed in the table.As it is clear from the results Some parameters are suitable for drinking water and some others higher than Standard level [3], we also tried to reduce pollutions using absorbing agents like Eggshell, Sycamore tree bark and their activated carbons and satisfactory results were found compared with other absorbers reported in scientific resources.
