Physicochemical characteristics of groundwater and municipal water in Amalner town by taking water samples from five different stations. The study was carried out by collecting four groundwater samples (Two open well, two bore well) and one municipal water sample during November 2007-February 2008. The results were compared with standards prescribed by WHO and ISI 10500-91. Total 15 parameters were analysed. It was found that the underground water was contaminated at few sampling sites namely Shirud Naka, Cotton Market and Shivaji Nagar. The sampling sites Dekhu road showed physicochemical parameters within the water quality standards and the quality of water is good and it is fit for drinking purpose. The correlation coefficients were calculated for water quality assessment.

Factor analysis was conducted to explain the characteristics and variation in the quality of water during the disassembly of oyster frames and fishery boxes. The result shows that the most important latent factors in the Tapeng Lagoon are the ocean factor, the primary productivity factor, and the fishery pollution factor. Canonical discriminant analysis is applied to identify the source of pollution in neighbouring rivers outside the Tapeng Lagoon. The two constructed discriminant functions (CDFs) showed a marked contribution to all the discriminant variables, and that total nitrogen, algae, dissolved oxygen, and total phosphate combined in the nutrient effect factor. The recognition capacities in these two CDFs were 95.6% and 4.4%, respectively. The water quality in the Kaoping river most strongly affected the water quality in the Tapeng Lagoon. Disassembling the oyster frames and fishery boxes improved the water quality markedly. However, environmental topographic conditions indicate that strengthening stream pollution prevention and constructing another entrance to the ocean are the best approaches for improving the quality of water in the Tapeng Lagoon by reducing eutrophication. These approaches and results yield useful information concerning habitat recovery and water resource management.

A comprehensive study for the spatial distribution of drinking water quality had been conductedfor residential area of Lahore, Pakistan. The study had made use of the geographic information system(GIS) for geographical representation and spatial analysis of groundwater quality. Physicochemicalparameters including electric conductivity, pH, TDS, Cl, Mg, Ca, alkalinity and bicarbonates from 73 ofthe water samples had been included in the analysis. Water quality data had been geo-referenced followedby its interpolation using inverse distance weighted (IDW) for each of the parameters. Very high alkalinityand bicarbonates values were observed in most parts of the area. For the comprehensive view, water qualityindex map had been prepared using weighted overlay analysis (WOA). The water quality index map wasclassified into five zones of excellent, good, poor, very poor and unfit for drinking as per WHO standardsof drinking water. 21% region had excellent quality of the underground water and 50% was found goodfor drinking. Poor quality of water was found in southeastern part, covering 27% of the study area. Only2% of the area was found under the very poor and unfit water quality conditions for drinking.

At present, the condition of surface water is much declining and the quality of water is a vital concern for mankind. It is directly linked with human security. Greater part of people is still not aware of it. So, improvement of the condition of surface water is a crying need. Surface water is often physically contaminated due to unhygienic practices. Discharges from various contaminated sources are very common thing in city life which deteriorates the water quality and necessary treatment is required to make water usable. The investigation is based on laboratory tests on water samples obtained from seven Ponds and three Charas of Sylhet City Corporation. The selected parameters for assessing the water quality are PH, Biochemical Oxygen Demand (BOD) and Dissolved Oxygen (DO). The present condition of Ponds and Charas water are not up to the mark and it is declining day by day. Proper initiatives need to take regarding the control of surface water pollution in Sylhet.

One can assess the quality of water by water quality index method and it is a mathematical method to evaluate the water quality based on physical or chemical parameters, using WQI one can evaluate the water quality of both ground water and surface water, while determining the WQI one can use the standards or guidelines provided by some standard organizations like WHO (world health organization), National Standard Body of India (BIS), ICMR (Indian Council for Medical Research) etc. To assign grade to the water samples under study, apart from the WQI there are some other popular techniques used to evaluate water quality they are statistical methods, multivariate statistics, neural networks, fuzzy logic and machine learning algorithms. The aim of this study is to give insight into various methods used or developed to evaluate water quality of both ground and surface water by earlier research works.

The modelling of water quality is an integrated source of good management, which benefits the environment and its people. In the present study, the quality of water was measured in terms of physicochemical analysis and WQI. This analysis facilitates the eco-management study of the water. In this article, we have measured the quality of the water in Taladanda canal and river Mahanadi nearby Paradip area in terms of WQI for the year 2017. Five different sampling stations were selected from Taladanda canal and nine sampling points were selected from river Mahanadi. It was found that the water quality index in most of the areas was much higher, however, the water is of poor quality. But in PPL site areas, the quality of water was found to be very poor and not suitable for human use. The pollution load was found to be much higher in the Taladanda canal and moderate in Mahanadi River near the Paradip area.

In this paper, the authors analyze the drinking water quality of Peshawar city due to which authors concluded that water quality assessment of 18 locations inside Peshawar of various union council. Groundwater samples were collected from a tube well and subjected to physical, chemical and biological analysis to check their suitability for the purpose of drinking. Results exposed that out of 18 samples 10 samples of water were found unfit for drinking purposes. In the 10, samples most of the effect on the water quality was from the chemical and biological contamination. It is concluded that the old defective supply system, infrastructure and storage, as well as their lack of maintenance are the reason behind the pollution of drinking water in Peshawar.

The paper presents the results of the physicochemical parameters of the springs of Andros which were studied to evaluate the chemistry of the major ions and solute acquisition processes, which control the chemical composition and the suitability of the quality of water for drinking use. Forty two samples were taken for physicochemical analysis almost at the end of the summer period, in September 2014. The Piper plot was used for the hydrogeochemical classification of groundwater which also indicated that the majority of groundwater samples belong to the Ca-Na-HCO3-Cl type. According to the Durov plot the majority of samples, can be positioned in field 2 in which a process of cation exchange is in progress. Also, the HCO3 /(HCO3 +SO4) ratio indicates a weathering process from carbonic acid. In general, the majority of samples can be characterized as potable.

Quality Of Water

Abstract Knowledge of uncertainty in analytical results is of prime importance in assessments of compliance with requirements set out for the quality of water intended for human consumption. Assessments of drinking water quality can be performed using either a deterministic or a probabilistic method. In the former approach, every single result is referred directly to the parametric value, while in the probabilistic method uncertainty related to analytical results is taken into account during the decision-making process. In the present research, laboratory uncertainty and uncertainty determined on the basis of results of analyses of duplicate samples collected in two Polish cities were compared and used in the probabilistic approach of water quality assessment. Using the probabilistic method, more results were considered to be “above the parametric value”. Most excesses were observed when the maximum allowable uncertainty as set out in the Regulation of the Minister of Health of 7 December 2017 was used, which is due to the highest values of these uncertainties. The lowest values above parametric values in the probabilistic approach were observed when measurement uncertainty was considered.
