Diarrheal diseases associated with inadequate supply of potable water are the leading causes of mortality among children under five years in developing countries. In Nigeria, women are the water managers in most households. However, there is dearth of information on the effect of women’s handling practices on drinking water quality. Therefore, this study was aimed at assessing the drinking water quality and handling practices among women in selected rural households in Oshimili North Local Government Area of Delta State, Nigeria. Paired drinking water samples from available sources and Household Storage Containers (HSC) were assessed for physico-chemical and bacteriological parameters using standard methods. The data obtained were compared with the WHO guideline limits. Water samples with 0, 1-10, 11-50 and > 50 E. coli/100 mL were graded as A, B, C, and D corresponding to excellent, acceptable, unacceptable, and grossly polluted quality, respectively. Pre-tested semi-structured interviewer-administered questionnaire was used to elicit information from the respondents. A 30-point scale was used to assess water handling practices. Handling practice scores greater or equal to mean handling practice score were grouped into good and those less than that were grouped into bad handling practices. Data were analyzed using descriptive statistics and One-way ANOVA at α = 0.05. The results showed physico-chemical parameters for both sources and households within WHO guideline limits. The mean total coliform counts for all sources and household containers exceeded permissible limits. E. coli  was not detected in harvested rain water while counts for borehole was 10.2 ±2.2 (A) and for stream sources was 44.6±33.3 EC/100 mL (B); drinking water stored in HSC had 36.8±32.3 (A) EC/100 mL, borehole had 62.31±33.2 (C) and stream had 30.00±33.2 (B). Mean handling practice score was 19.4+6.6. Majority (60.0%) practiced some water handling technique. Drinking water from assessed sources was of poor microbial quality and it significantly deteriorated when stored in household storage containers. Therefore, there is a need to improve the microbial quality of drinking water at sources and household level through the supply of simple, acceptable, low-cost treatment methods and hygiene education.

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

Bottled water is generally considered safe for drinking. However, several studies have reported the substandard quality of bottled water. Physico-chemical assessment of ten different brands of bottled water distributed in Bhaktapur Municipality was carried out from January 2018 to March 2018. In total, one hundred bottled water samples consisting of ten different brands were collected randomly from various retail outlets. Eight selected physico-chemical and microbiological parameters were analysed following standard methods, and the results were compared with the Nepal Drinking Water Quality Standard (NDWQS) (2005). Out of one hundred samples, sixty-nine samples did not comply with the standard pH limit. Other physico-chemical parameters were found to comply with the standard though variations were observed in the concentrations among different brands. Microbial contamination was not found in any brands of the bottled water samples considered in this study. However, it is necessary to examine other contaminants such as heavy metals, minerals, and chemicals to know the overall quality of water. Moreover, the regulatory bodies are required to strictly monitor water processing companies for the maintenance of the quality of bottled water.

Abstract Despite its importance, legal regulations and official guidelines regarding the quality of livestock drinking water are rather unspecific. The study aimed to investigate biological livestock drinking water quality considering influences of risk factors and relations to biofilm development and hygiene status of dairy troughs. On 24 dairy operations in Western Germany, 105 troughs were sampled. Water and biofilm were analyzed for aerobic total viable count (TVC), coliform count (CC), Escherichia coli, methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum beta-lactamases building bacteria (ESBL). 33 possible influences on biological water quality for each trough were either recorded or inquired. The troughs surface was examined with protein- and adenosine triphosphate (ATP)-rapid tests for hygiene. A mixed model and Spearman rank correlations (SAS 9.4) were used for estimating the probability of quality impairment in relation to recorded influences. Average TVC in water samples was 4.4 log10 cfu/ml. Coliforms were detectable in 94.3% of all troughs and E. coli in 48.6%. CC seems to be a more sensitive and suitable indicator to check fecal contamination because 16 water samples were positive for CC (>2.0 log10 cfu/ml) but negative for E. coli. MRSA were found in livestock drinking water of a single, and ESBL on three farms, suggesting that troughs might contribute to an exchange of antibiotic resistant bacteria in some dairy farms. Risk factors (P < 0.05) for at least one quality criteria (TVC, CC or E. coli) were water origin, trough type, degree of trough soiling, visible biofilm, ambient temperature and distance to the milking parlor. Water CC (r = 0.46; P < 0.001) and E. coli (r = 0.31; P < 0.01) correlated with their equivalent in biofilm and with hygiene tests on trough surfaces (0.31 >r >0.19; P < 0.05). Biological livestock drinking water quality can be improved by addressing the risk factors and be monitored with hygiene tests.

Chattogram is the second most populated city in Bangladesh. This port city faces a serious threat mainly due to the lack of safe drinking water. This study was conducted for determining drinking water quality of groundwater sources in Chattogram city. The study was performed in the BCSIR laboratory, Chattogram. It was carried out for a period of six months from 1st July, 2018 to 31th December, 2018. Total six water samples were collected from three different locations (Baluchora, C&B colony and Khulshi area). Each sampling location consists of two separate sampling points. Physicochemical parameters of the collected samples like Temperature, pH, Electrical Conductivity (EC), Total dissolved solid (TDS), Hardness, Turbidity and concentration of Cl, As, Mn, Fe, Pb, Cr and Cd were examined. Microbial parameters like Total Coliform (TC) were also measured. All the analyzed parameters compared with BSTI and WHO drinking water quality standards to understand the overall ground water quality status of the study area. The results reveal that water samples in almost all locations were contaminated with microbial contamination and that the range of physico-chemical parameters was not adequate for consumption. Preliminary treatments like boiling, filtering etc are required before using groundwater for drinking and the necessary measures must be taken for a safe alternative source of drinking water.

This case study characterizes the drinking water quality by using the multivariate technique. The spatial variation of the physico-chemical and heavy metals parameters toxicity with the drinking water quality based on 28 water treatment plants in Selangor, Malaysia from 2009 to 2012 was evaluated. The objectives of this study are to analyze the physio-chemical activities and heavy metals activities in the collected drinking water samples from the treatment plants, and to detect the source of pollution for the most revealing parameters. The discriminant analysis (DA) and the principal component analysis (PCA) are the chemometric techniques used to investigate the spatial variation of the most significant physico-chemical and heavy metal parameters of the drinking water samples. The classification matrix accuracy for standard mode of DA, forward stepwise and backward stepwise for the physico-chemical and heavy metal parameters are excellent. PCA highlighted 13 significant parameters out of 18 physico-chemical water quality parameters and 14 significant parameters out of 16 heavy metal parameters. PCA was carried out to identify the origin and source of pollution of each water quality parameters. For that reason, this study proves that chemometric method is the principle way to explain the characteristic of the drinking water quality.

The quality of drinking water and its health implications for school children were examined at schools in the Santarém region, Amazon, Brazil. In this region, the population is fully supplied by groundwater from the voluminous Alter do Chão aquifer. Drinking water samples from three schools in Santarem city and from one school at the rural Mojuí dos Campos town were subjected to microbiological and physicochemical compositional analyses. The health risk of human exposure to chemical compounds through water intake was also evaluated. The results indicated that most water samples were contaminated with total coliform and with E. coli, which could cause serious intestinal disorders for school children. Drinking water was acidic and most of the chemical element concentrations were within Brazilian water potability recommended levels. One exception was the high aluminium content in schools from Santarem served by shallower wells, suggesting that further epidemiological studies are necessary and the monitoring of exposed school children should not be discarded. Elevated nitrate concentrations were also noted in schools from Santarém with shallower wells, indicating lack of sanitation and the importance of periodic monitoring of drinking water to prevent adverse health effects. Quantification of human health risk indicated a hazard in schools served by shallower wells, with aluminium as the main pollutant, followed by nitrate. The results showed that most drinking water quality parameters are in accordance with Brazilian legislation. However, microbiological contamination, water acidity, aluminium and nitrate concentrations must be taken into consideration for local governments in order to prevent related diseases among school children.

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
