An analytical FIS model to check the quality of drinking water

The quality of water is an important aspect of today's time. The standard for drinking water has always been a debatable issue as there are various attributes affect this standard. This paper observes various attributes of water and works with three important attributes such as conductivity, pH value and hardness of water. A fuzzy model is proposed that requires three said inputs and is then simulated in MATLAB. The model gives the percentage of quality of water. A data set consisting of three said attributes is created from various water samples collected from different parts of Uttar Pradesh, India. The result is quite satisfactorily and is validated through government data. The present work may be embedded with several other applications also such as crop sowing and farming etc.
