Groundwater is an essential source because of its high quality and continuous availability characterize this water resource. Therefore, the study of groundwater has required more attention. The present study aims to assess and manage groundwater quality's suitability for various purposes through the Geographical Information System GIS and the Water Quality Index WQI. The study area is located in the city of Baghdad in central Iraq, with an approximate area of ​​900 , data were collected from the relevant official departments representing the locations of 97 wells of groundwater in the study area for the year 2019, as it included physicochemical parameters such as  pH, EC, TDS, Na, K, Mg, Ca, Cl,  , and  . It used (kriging method) in the geographic information system to generate the groundwater physical and chemical parameters' spatial distribution and the water quality index map. To estimate the water quality index, ten parameters were considered  pH, TDS, Na, K, Mg, Ca, Cl,  ,  , and  . The estimated WQI value for groundwater samples in the study area ranges from 50 to 300. Based on the analysis, most of the area under study falls approximately 70% in poor water class and 30% in good water class, where the distribution of the groundwater samples with respect to their quality classes such as excellent, good, poor, very poor and unfit for human drinking purpose, was found to be 3 %, 30 %, 33 %,  12 %, and 20 %, respectively.

Quality Of Water

The present investigation is an extensive study of surface and ground water quality of Madathukulam taluk, Tiruppur District, Tamil Nadu, India, to estimate the quality of water using Modified Water Quality Index (MWQI) and Geographic Information System (GIS) technique. In this study 35 water samples from Open well, Bore well, River, Lake and Pond were analysed for the physicochemical parameters like pH, temperature, total phosphate, total nitrate, turbidity, total dissolved solids, dissolved oxygen, biological oxygen demand, faecal coliform, electrical conductivity, total hardness, chloride, fluoride, sodium and potassium. The resulting values were computed to investigate the quality of water using geographic information system and water quality index and compared with the standard drinking water guidelines proposed by the WHO (2017) and BIS (2012) for drinking and agricultural purpose. Inverse distance weighted (IDW) interpolation technique was used for preparing the spatial distribution maps for each physiochemical parameter. The analytical result signifies that 40% of the study areas are slightly acidic. GIS based water quality index shows that 63% of the area has recorded with good quality water, while the remaining 37% are of medium quality of water. The MWQI proved to be a useful method to classify the water similar to NSF-WQI in Madathukulam Taluk.

Maluku is one of the archipelago province in Indonesia that has small pelagic fish resources with widespread distribution, such as lompa (Thryssa baelama Forsskål). One of lompa habitat in Mollucas is in Apui coastal areas. The presence of lompa depends on physical and chemical parameters in the waters. This study aims to determine the influence of physical and chemical parameters on the presence of lompa in Apui coastal area Central Mollucas. This study was conducted in June - July 2015. This research is ex-post facto using the value of Environmental Water Quality Index which refers to US-National Sanitation Foundation-Water Quality Index (NSF-WQI). Physical and chemical parameters measured include temperature, velocity, depth, brightness, salinity, pH and dissolved oxygen. The results of calculations with the Indeks Mutu Lingkungan Perairan (IMLP) are 95.61; 92,15; 88.61; 96,37; 93,76; 79.57. And the results of lompa fishing were 181, 162, 205, 173, 184, and 97 respectively. The research conclusion is that the Apui coastal areas are in good condition and potential as lompa habitat.
