Groundwater is the most important natural resource used for drinking by many people around the world, especially in arid and semi-arid areas. Groundwater is the major source of drinking water in rural as well as in urban areas and over 94% of the drinking water demand is met by groundwater. The study was carried out to assess the ground water quality and its suitability for drinking purpose in Darulaman, Kabul Afghanistan. For this purpose, four water samples collected from bore wells of villages of study area were analyzed for different chemical parameters such as pH,total, magnesium hardness, sodium, chloride, nitrate, fluoride, cyanide. The results of analysis carried out showed the following concentration ranges: pH value in this research found from (7.423 to 7.45, calcium hardness from (96.19 to 192.3) mg/L. Magnesium hardness varied from (40.2 to 90.14) mg/L and chloride from (0.02 to 17) mg/L. Values of nitrate concentration varied from (0.5 to 3.5) mg/L and fluoride from (0.22 to 0.41) mg/L., cyanide from ranges (0.002 to 0.007. The study reveals that almost all parameters were exceeding the permissible limits. As per the desirable and maximum permissible limit for fluoride, nitrate, total dissolved solids and chloride in drinking water, determined by WHO standards, groundwater sources are unfit for drinking purposes respectively. After evaluating the data of this study, it is concluded that drinking water of Darul Aman is not potable and there is an instant need to take ameliorative steps in this region to prevent the population from adverse health effects.

Abstract Periodic quality assessment of drinking water sources is necessary to guarantee the quality and security of water supply to people. Accordingly, this study assessed the drinking water quality of spring water of some villages located in Barwari Bala region of Duhok Governorate, Kurdistan region, Iraq, using the water quality index (WQI). To realize this objective, 120 spring water samples were collected from ten villages during the dry and wet seasons in 2018 and were analyzed for major physicochemical characteristics, including: calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), chloride (Cl−), sulfate (SO42−), nitrate (NO3−), pH, total dissolved solids (TDS), turbidity, total hardness (TH) and total alkalinity (TA). The results for pH, turbidity, sodium, potassium, chloride, sulfate and nitrate showed that the water samples at all the sampled springs were suitable for drinking and within permissible limits based on given standards. However, TDS, TA, calcium and magnesium exceeded the permissible limits at some sites. It was also observed that, except for SO42−, at almost all the sites, the majority of parameters were significantly greater during the wet season compared to the dry season. With reference to all the parameters, the WQI values ranged from 10.76 to 18.13 during the dry season and from 17.10 to 20.45 during the wet season, indicating that all water samples are classified as having “excellent” water quality for drinking purposes. The calculation of WQI based on specific parameters, where values were close to or exceeded the maximum acceptable limits, showed that the water quality status of all water samples was “good” quality, except for sites S6 and S8, which were classified as “poor” quality and are not considered suitable for drinking purposes without treatment. Water from almost all the sampled spring sites can be considered as suitable for drinking purposes, although some parameters exceed permissible limits. Simple filtration treatment of the sampled spring water before use is desirable for ensuring good quality and security of the water supply to people of these areas.

The present study was carried to evaluate the physico-chemical parameters and microbial contamination of drinking water in the area of Saggiyan, Lahore. The tested water samples (S1-S30) were found to contain 199.6-402 mg/L TDS, 196-260 ppm EC, 196-260 ppm Hardness, 0.8-17 NTU turbidity, 169-290 mg/L alkalinity, 0-0.1 ppb arsenic and 0-0.1 ppm fluoride contents. 95% of the water samples were found contaminated with fecal coliforms while 27% of the samples had shown the presence of E. coli. Though the physico-chemical parameters of most water samples were found in the safe limits of WHO, however, the presence of microbial contamination rendered it non-suitable for drinking purposes.

In the current study, the quality of ground water (GW) from an area of western part of Jorhat district of Assam (India) was assessed in order to ensure the safety of its use in irrigation and drinking purposes. The physico-chemical parameters of the collected GW samples were evaluated and compared the data with the Indian Standards (IS) for drinking purposes. The investigation was mainly emphasised on the evaluation of Water Quality Index (WQI) and different parameters for the quality measurement of water for drinking and irrigation purposes, respectively. Correlations among the physico-chemical parameters were evaluated through statistical analysis. The physico-chemical parameters revealed that almost all the parameters except iron were within the permissible limit. Arsenic was found to be present in few water samples in both seasons (pre and post monsoon). In both the seasons, the WQI of the majority of collected water samples were observed to be falling under the poor category for drinking. Almost all the collected water samples were found to be fit for irrigation purposes. However, based on sodium percentage (Na %), Kelly’s ratio (KR), and Magnesium ratio (MR), few of the water samples are classified to be doubtful and inappropriate for irrigation.

Monsoons provide Bangladesh with ample rainwater. However, many regions, both rural and urban, suffer from shortage of safe drinking water. While arsenic contamination of ground water affects many rural areas, some urban areas, including Dhaka City, also lack of sufficient potable water supply due to shortage of surface water. This research explored the quality of stored rainwater as well as the feasibility of harvesting monsoon rainwater as a source of drinking water. Rainwater had been experimentally harvested at Bangladesh University of Engineering and Technology in Dhaka using a simple traditional technology. The rainwater was collected using a small catchment area (4.57 m × 4.57 m) made of water-proof cloth and a 3.2 m3 capacity ferro-cement storage tank, attached with an automatic initial flushing device, for a family having five members for four months. Initial test results indicated that the stored rainwater had a slightly higher pH value (8.1 to 8.3) and presence of total coliform after three months of storage. The traditional filtering system removed contaminants completely and the total coliforms up to 60%. This research supports the viability of traditional filtering of harvested rainwater as a promising solution to potable water shortage in Bangladesh.

AbstractThe genus Klebsiella is seemingly ubiquitous in terms of its habitat associations. Klebsiella is a common opportunistic pathogen for humans and other animals, as well as being resident or transient flora (particularly in the gastrointestinal tract). Other habitats include sewage, drinking water, soils, surface waters, industrial effluents, and vegetation. Until recently, almost all these Klebsiella have been identified as one species, ie, K. pneumoniae. However, phenotypic and genotypic studies have shown that “K. pneumoniae” actually consists of at least four species, all with distinct characteristics and habitats. General habitat associations of Klebsiella species are as follows: K. pneumoniae—humans, animals, sewage, and polluted waters and soils; K. oxytoca—frequent association with most habitats; K. terrigena— unpolluted surface waters and soils, drinking water, and vegetation; K. planticola—sewage, polluted surface waters, soils, and vegetation; and K. ozaenae/K. rhinoscleromatis—infrequently detected (primarily with humans).

The article presents the results of studies of osmolality and pH of 0,9 % sodium chloride of various manufacturers. To obtain data on the pH value, the data used in the passports are used, and the indicators of its osmolality are de- termined using laboratory tests. 0,9 % sodium chloride from different manufacturers has different pH and osmolality. Knowing the actual values of physico-chemical parameters can increase the accuracy of the results of future clinical studies, which compare the pharmacokinetics and pharmacodynamics of modern plasma-substituting solutions and a solution of 0,9 % sodium chloride.

Well field management in urban areas faces challenges such as pollution from old waste deposits and former industrial sites, pollution from chemical accidents along transport lines or in industry, or diffuse pollution from leaking sewers. One possibility to protect the drinking water of a well field is the maintenance of a hydraulic barrier between the potentially polluted and the clean water. An example is the Hardhof well field in Zurich, Switzerland. This paper presents the methodology for a simple and fast expert system (ES), applies it to the Hardhof well field, and compares its performance to the historical management method of the Hardhof well field. Although the ES is quite simplistic it considerably improves the water quality in the drinking water wells. The ES knowledge base is crucial for successful management application. Therefore, a periodic update of the knowledge base is suggested for the real-time application of the ES.
