Are the “Kits for Field Tests”, available in market, useful to determine the chemical potability of water?
The commercial kits for tests of chemical parameters such as Chlorides, Fluoride, Hardness, Nitrate, Iron, Residual chlorine etc. are available in the market may be used for field level analysis, and they can show the present/absent status and certain quantity range of constituents of your water and can suggest a guideline of the status of water as safe, marginal safe or unsafe. But detail quantitative chemical analysis can be done in the Laboratory only.
