Water Contaminant Measurement Using Pollution Indexing in Case of ground water

One important factor in human life is the need for water used for bathing, washing, and others. Water quality is determined by the chemical, physical, biological, and radiological characteristics of water. It is a measure of water conditions that are based on the feasibility of use for example used by humans in their lives. Water pollution can be measured by analyzing water samples in physical, chemical and biological tests. Specific contaminants that lead to water pollution include chemical and physical changes such as temperature and discoloration. In this study, a water contaminant measuring instrument was made based on related sensors by utilizing water characteristics from pH, turbidity, temperature, Total Dissolved Solids (TDS) and Oxidation Reduction Potential (ORP) indicators. Calibration of the system is conducted manually by applying the pollution index (PI) method. The proposed system involves a sensor technology and a set of embedded processing systems that are able to make decisions in indication of water pollution. This system has 4 main features: (1) Making measurement with water quality sensors, (2) Data acquisition and pre-processing, (3) Intelligent processing units, (4) Data transmission and visualization. Three parts of the system are (1) Data acquisition unit, (2) Console Unit, and (3) Web visualization. We conducted an experimental study water contaminant measurement at groundwater source points (wells) using a Pollution Index. Based on the experiments, our proposed system measured water contaminants successfully; including can make decision of the water contaminants category. (paper)
