This manual introduces the application of basic chemistry and chemical calculations to measure physical, chemical, and bacteriological parameters like turbidity and colour, dissolved oxygen, hardness, pH, alkalinity, organic content, Sulphates, Fluorides, Iron, Total Settle able solids, chloride, Suspended and Dissolved Solids, Ammonical Nitrogen, Bacteriological Analysis, chemical and biochemical oxygen demand of water and wastewater. Laboratory methods and interpretation of results with regard to environmental engineering applications such as design and operation of water and wastewater treatment processes, and to the control of the quality of natural waters are also explored. As a result of these tests, various remedies can be suggested to reduce the environmental pollution. The purpose of this laboratory manual is to make the people aware of the dangerous effects of environmental pollution
