RESUMO
Drinking water samples was collected from lake and silver cascade water falls in Kodaikanal were analyzed for physico- chemical characteristics. Vetiveria zizaniodes and Terminalia chebula plant extract were examined as natural alternative materials for drinking water treatment. The results was compared with the WHO standards of drinking water quality parameters namely pH, electrical conductivity, COD, magnesium, alkalinity, and sulfate, total dissolved solids and total hardness, dissolved oxygen, iron, fluoride. The result showed that, V. zizaniodes enhanced the water quality than T. chebula in terms of (denoted values). Therefore, the use of plant materials with low cost natural absorbents is recommended for eco-friendly, nontoxic, simplified water treatment.
