The paper proposes fuzzy logic model that deals with the physico-chemical water analysis of ground water of Chikhli town for determination of Water Quality Index (WQI). The study was carried by collection of ground water samples from about eleven hand pumps located in this town. Ground water quality is studied by systematic collection and analysis of samples. The fuzzy logic is used for the deciding the water quality index on the basis of which, water quality rankings are given to determine the quality of water. The Water Quality Index presented here is a unitless number ranging from 1 to 10. A higher number is indicative of better water quality. Around 81% of samples were found suitable for drinking purpose. It is also observed that all the parameters fall within the permissible limits laid by WHO, ISI, and ICMR, except Total Hardness, Calcium and Magnesium. The quality parameters were compared with standards laid by the World Health Organization (WHO), Indian Standards Institute (ISI) and Indian Council of Medical Research (ICMR) for drinking water quality.

The objective of the research was to apply the methodology for the determination of the ICA-PE water quality index in the Escalera river of the Huachocolpa district in the periods of 2015 and 2018, the samplings carried out were given 2 points (REsca1 and REsca2), For data collection, it was based on mathematical simulation, documentary analysis and registration, at the sampling points the concentrations of aluminum, arsenic, cadmium, copper, iron, manganese, lead and zinc were determined, these parameters exceeded the environmental quality standards. Water (ECA-AGUA) was later categorized according to the ICA-PE water quality index, of which for 2015 it was of good quality obtaining a value of 73.14 and for 2018 its quality decreased to regular reaching a value of 61.85 . The results obtained show that the quality of water is decreasing in its path that runs through the Escalera river, due to the different anthropogenic activities that take place around it, altering its quality and reducing its capacity for self-purification.

Bandung Metropolitan Area (BMA) region is the upper watershed of Citarum with an area of ± 2338 km2. The status carried by BMA as a National Strategic Area from the perspective of economic encourage the increasing migration flows to BMA. These circumstances lead to an imbalance between supply and demand, in which on the one hand, demand for clean water is increasing. The potency of Saguling Reservoir as an alternative of raw water of BMA region in terms of quantity in this research was determined based on the determination of mainstay discharge. In this study, the intake site selection 11 monitoring posts will be carried out by reviewing the concentration of all parameters in Government Regulation No. 82 Year 2001 on any division of discharge grade using 5-grade Makov Discrete method (very dry, dry, normal, wet and very wet). In addition, the calculation of the value of Water Quality Index (WQI) was done at each monitoring station for each division of discharge grade that has been done. The series of data flow and concentration parameters used in this study start from the year 1999 to 2014. The allocation of raw water discharge calculation for Saguling Reservoir in order to fulfill the needs of raw water in Bandung Metropolitan Area is 46,92m3/second (R5 dry for irrigation raw water supply and 29,53 92 m3/second (R10 dry for drinking water supply). Based on the assessment of the concentration of measured parameters and determination of Water Quality Index, it can be found that around Muara Ciminyak location is the most qualified location to be used as drinking raw water intake for Bandung Metropolitan Area. Based on this study, it also notes that the determination of the concentration of pollutant parameters needs to be done on the each division of discharge grade occurred.
