From the tests conducted above, the values obtained for hardness, chlorine, sulphate and alkalinity for all samples ie, well samples as well as surface water samples are within the permissible limits. But the values of iron, DO, BOD and COD are not within the acceptable limits. The iron and DO showed lower variations from the permissible limits, but COD and BOD shows higher variations. In case of well water samples, higher values are at the near areas to the rice mill. Also, for surface water samples highest values are at the discharge point and downstream when comparing with the upstream sample. So it is apprehended that surface water as well as groundwater may get polluted by the waste water from the rice mill and not suitable for drinking considering iron, BOD, COD and DO as criteria.
