Abstract Regular monitoring of microbial quality of water used for drinking is an important aspect of public health. Microbiological quality, using a novel microbial water quality test kit – Compartment Bag Test (CBT; AguaGenX, LLC, Chapel Hill, NC, USA), and physical parameters (pH, dissolved oxygen, turbidity, temperature and electrical conductivity) of 94 different water sources used by communities in the Ahenema Kokoben area of Ghana for drinking were tested. Using the WHO drinking water quality risk categories for the presence of Escherichia coli indicator bacteria, only 56% (53/94) of the water sources were safe for drinking, while 29% (27/94) of the water sources were classified as high risk and unsafe for human purposes. Some of the physical parameters were also higher than guideline values and could have been a contributing factor to poor water quality. Overall, the CBT proved to be a reliable alternative to traditional and laboratory-dependent microbial drinking water quality tests which can be easily used by water authorities to make sure that water is safe to drink.

Water Quality And Quantity

The need for water quality research on the Tibetan plateau has arisen after the rangeland was allocated and leased as pasture grounds to individual nomadic families in the 1990s. These policies changed the access to water sources. The imposed fencing of the pasture tenures makes the situation even more delicate. Nomadic families are now obliged to use only water sources existing on their own site. The restrictions have caused the urge to use all available water, which resulted in increasing water quality and quantity problems. In the past, natural water sources were in common use. During the Collective era, machine-dug wells near the collective settlements facilitated the procurement of drinking water. Based on recent investigations in Dzoge county (Sichuan province), the nomadic families of some regions considered the availability of adequate drinking water for humans and animals as their biggest problem. For this study, eight water samples were collected from the Dzoge county area. All samples were from different kinds of sources, but all in continuous use by humans and animals. The samples were analyzed for typical potable water quality factors (hygienic and technique-aesthetic). The results show that the Chinese national guideline values were exceeded for NO4-N and PO4-P in most open sampling locations. Those parameters do not spoil the water by themselves, but together with suspended solids and organic materials produce a great environment for bacteria like E. coli and fecal streptococci to grow. The result analysis and pictures seen from the location reveal that bacterial growth may be the biggest problem in water quality. Even primitive protection around the water source (i.e. concrete rings, wooden barriers around edges, covers) seem to have a great impact on water quality.

Quality Status

This study assesses the rural drinking water quality status in Central Development Region of Nepal. With a total of 250 samples collected from 15 districts of the region, drinking water quality of spring water and ground water representing hill and Terai (lowland) regions were tested and compared for their physicochemical parameters and faecal coliform contamination.None of the spring samples as well as ground water samples violated National Drinking Water Standards (NDWS) for electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), appearance, chloride and nitrate. Similarly none violated the standards for total hardness (TH) indicating soft nature of the water. The spring samples were within the NDWS for manganese (Mn) and iron (Fe) whereas 15.4% and 39.0% of the ground water samples violated the standards for manganese and iron, respectively. Gravity water is found to be more alkaline than ground water. Faecal coliforms were the most problematic in both types of sources followed by Ammonia (NH3) and pH in spring sources and by iron, Mn, pH and ammonia in ground water sources, respectively. Spring sources were more contaminated by bacteria than ground water sources. Correlation and regression analysis revealed highly significant correlations between EC and TDS (r=0.979) and between CaH and TH (r=0.988) in ground water suggesting that aquifer chemistry of ground water to be mainly controlled by EC, TDS, TH, and CaH. Similarly, highly significant correlations were found between the following pairs in gravity water: EC and TDS (r=0.983), TA and TDS(r=0.853), CaH and TDS (r=0.912), TH and TDS (r=0.955), EC and CaH (r=0.898), and between CaH and TH (r=0.951).DOI: http://dx.doi.org/10.3126/hn.v9i0.7074 Hydro Nepal Vol.9 July 2011 52-56

Qualitative composition of the drinking water from underground sources of the decentralized water-supply of the Polissya region with intensive agriculture has been analysed. The sanitary inspection of water sources was conducted. Monitoring of underwaters quality testifies the admissible content of chlorides which are within the normative limits, but fluorides are considerably less than physiological requirements. High level of iron was registered in all studied districts but the nitrate-ion is in Naroditscky and Popylyansky districts. In Naroditscky and Ovrutsky districts the quality of drinking water may be characterized as moderately polluted. Advices on the improvement of the drinking water quality are proposed.

Background Clean water is an essential part of human healthy life and wellbeing. More recently, rapid population growth, high illiteracy rate, lack of sustainable development, and climate change; faces a global challenge in developing countries. The discontinuity of drinking water supply forces households either to use unsafe water storage materials or to use water from unsafe sources. The present study aimed to identify the determinants of water source types, use, quality of water, and sanitation perception of physical parameters among urban households in North-West Ethiopia. Methods A community-based cross-sectional study was conducted among households from February to March 2019. An interview-based a pre-tested and structured questionnaire was used to collect the data. Data collection samples were selected randomly and proportional to each of the kebeles’ households. MS Excel and R Version 3.6.2 were used to enter and analyze the data; respectively. Descriptive statistics using frequencies and percentages were used to explain the sample data concerning the predictor variable. Both bivariate and multivariate logistic regressions were used to assess the association between independent and response variables. Results Four hundred eighteen (418) households have participated. Based on the study undertaken,78.95% of households used improved and 21.05% of households used unimproved drinking water sources. Households drinking water sources were significantly associated with the age of the participant (x2 = 20.392, df = 3), educational status (x2 = 19.358, df = 4), source of income (x2 = 21.777, df = 3), monthly income (x2 = 13.322, df = 3), availability of additional facilities (x2 = 98.144, df = 7), cleanness status (x2 = 42.979, df = 4), scarcity of water (x2 = 5.1388, df = 1) and family size (x2 = 9.934, df = 2). The logistic regression analysis also indicated that those factors are significantly determining the water source types used by the households. Factors such as availability of toilet facility, household member type, and sex of the head of the household were not significantly associated with drinking water sources. Conclusion The uses of drinking water from improved sources were determined by different demographic, socio-economic, sanitation, and hygiene-related factors. Therefore; the local, regional, and national governments and other supporting organizations shall improve the accessibility and adequacy of drinking water from improved sources in the area.

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.

Microbiological Characteristics

This study evaluates the effects of gas flaring on the physico-chemical and microbiological characteristics of water sources at Egbema, Imo State, Nigeria. Surface and ground water samples from the area were compared with samples from Ihiagwa Autonomous Community in Owerri West, a non-gas flared community. Both water sources were then compared with WHO standards for drinking water. The results revealed that water sources from the gas flared area have high levels of temperature, total chlorine, nitrate, nitrites, sulphates, calcium, and zinc, chromium with a very acidic pH when compared with water from non-gas flared sources. Also, microbial load increased the farther the distance from the flare site. The human health imparts of the presence of heavy metals and microorganisms in drinking water had been reported. In conclusion, gas flaring can pollute water sources within oil and gas facilities, thereby making them unsuitable for human consumption. Oil and gas industries should therefore treat water within their areas of operations before discharged into water bodies in addition to other remediation measures as part of their social responsibility.

The study was undertaken to assess the existing status of drinking water quality of Madhyapur-Thimi. A total of 105 water samples comprising 50 (47.61%) wells, 45 (42.82%) tap water and 10 (9.52%) stone spouts were randomly collected. The physicochemical and microbiological parameters were analyzed following standard technique. The pH (1.9%), conductivity (34.28%) and turbidity (16.19%) of water samples had crossed the permissible guideline values as prescribed by WHO and national standard. All samples contained nitrate values within the WHO permissible value as well as national standard but hardness (2%), chloride (2.85%), iron (26.66%), ammonia (11.42%), and arsenic content (1.90%) crossed the WHO guideline value but none of the water samples crossed the national standard for arsenic. Arsenic having 0.025mg/l (25ppb) was detected from two well water samples, Makanani well and Ajimanani well. Total coliform count showed 64.76% of samples crossed the WHO guideline values. Eleven different kinds of enteric bacteria were isolated from different sources, Enterobacter spp. being the predominant. Isolates were subjected for antibiotic susceptibility pattern using ten antibiotics. Among total isolates, resistance was directed to 79.5% Erythromycin, 62.67% Penicillin G, 61.9% Amoxycillin, 34.5% Ampicillin, 21.1% Tetracycline, 15.4% Ceftriaxone, 14.7% Amikacin, 14.7% Cephotaxine, 5.6% Chlorophenical and 5.6% Ofloxacin respectively.Key words: Coliform; Enteric bacteria; Permissible value; Physicochemical; Antibiotic resistanceDOI: 10.3126/njst.v10i0.2955Nepal Journal of Science and Technology Vol. 10, 2009 Page: 167-172

Large dams play an important role in promoting economic and social development in many countries. However, the construction of such dams can have a detrimental effect on the environment. The aim of this study was to investigate perceptions of drinking water quality among inhabitants of selected communities within the Bui Dam environs. With the help of questionnaires, 100 respondents from communities “near to the dam” were randomly selected and interviewed. Their responses were compared with another 100 respondents selected from “far from the dam” communities. These were augmented with in-depth interviews, focus group discussion, and personal observation. Analysis of the results showed that, there were greater proportions (31%) of the participants who lived in “near communities” within the age category 20–25 compared to 19% of their “far communities” counterparts. There were significantly greater proportions of female respondents in the “near to the dam” (57%) compared to respondents in the “far from the dam” communities (52%). The study further showed that the perception of risk of consuming contaminated drinking water was more common among “far from the dam” communities (odds ratio = 4.57). The perception of the quality of water based on some physical properties was investigated as part of our study. Analysis of the results showed that significantly greater proportion of the “far from the dam” communities (35%) perceived their water had an objectionable smell compared to 7% of inhabitants of their other counterparts (p value = 0.001). The study further showed that significantly greater proportion of the study participants in the far from the communities perceived that their water had colour (65%) and they did not drink water from any other source (63%) apart from their stream. The study demonstrated that generally, inhabitants within the study communities perceived the construction of the Bui Power Project has negatively affected their drinking water quality.
