Water is maybe the most valuable regular asset after the air. However, the outer layer of the earth is generally comprised of water, just a little piece of it is usable, which makes this asset exceptionally restricted. This valuable and restricted asset, consequently, should be utilized with reasonability. As water is expected for various purposes, its reasonableness should be checked previously use. Likewise, wellsprings of water should be checked routinely to decide if they are in strong well-being or not. The poor state of water bodies is not just the indicator of natural corruption, it is additionally a danger to the environment. In ventures, the inappropriate nature of water might cause risks and extreme monetary misfortune. Subsequently, the nature of water is vital from both ecological and financial perspectives. Hence, water quality examination is fundamental for involving it in any reason. Following quite a while of examination, water quality investigation is currently comprised of a few standard conventions. There are rules for inspecting, safeguarding, and examination of the examples. Here the standard chain of activity is examined momentarily so it very well might be valuable to the examiners and scientists. The current review is centered around the assurance of physio-substance boundaries, like temperature, pH, EC, hardness, chlorides, alkalinity, DO, BOD5, COD, phosphate, and sulfate of water tests from various examining focuses. Increment in contamination focus shows an expansion in the contamination load because of homegrown sewage and modern effluents and anthropogenic exercises and the release of squanders to the release into the stream in Erode region. In the current review, water tests were gathered from the entire city and were separated into four locales for efficient inspection and understanding. The outcomes uncovered that the normal pH esteem was examined as 7.86, Electrical Conductivity was 920 µS/cm-1, boundaries incorporate Total Solids 1580 mg/l, Total Dissolved Solids 1004 mg/l, complete suspended solids was 690 mg/l, absolute hardness was 340 mg/l, chloride was 380 mg/l, broke up oxygen was 5.59 mg/l, BOD5 was 38 mg/l, COD was 304 mg/l, phosphate was 6.0 mg/l and sulfate was 60 mg/l of the stream water test. In this way, the review uncovered how the Cauvery stream water is sullied by effluents from limited scope enterprises and unloading of wastages from business sectors and homegrown use wastages. So, water quality the board is direly expected to accomplish the water quality norms not entirely set in stone by WHO. The correlation coefficient showed an exceptionally critical positive what's more, negative relationship.
