Estimation of Hardness of Water in Selected Areas in East Godavari Dist. Andhra Pradesh, India

Water is most essential thing than after the air, sustained on the earth surface of living things and non living things based on the availability of water. This concludes no water – no life. Availability of water depends on the type of source water. Source water is useful for all purposes are called drinking water, not useful for domestic, industrial and agricultural is called waste water. It may classify based on the purpose of use and containing compounds into two types i.e. 1) Soft water 2) Hard water. Salts of magnesium and calcium is present in the water is the reason for hardness. Hardness water again two types permanent hard water and temporary hard water based on the presence of salts. So need to estimate the hardness of water is fit or not according to the standard guidelines by BSI, ICMR. In this experimental Titrimetric analysis, concludes the hardness of the testing sample water in the selected area, containing industrials so my experimental / analytical study may help to study the type of water hardness to be determine. Titrimetric method is used to determine the hardness by using EDTA (Ethylene Diamine Tetra Acetic acid) complexometric compound. For this study to be observe different types of water like ground (bore / well) water, surface (river) water, drinking water.
