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.

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 pollution is one of the significant dangers to general wellbeing in Bangladesh. Drinking water quality is inadequately overseen and checked. Bangladesh positions at number 86 among 142 countries with respect to drinking water quality. Drinking water sources, both surface and groundwater are debased with coliforms, harmful metals and pesticides all through the nation. Different drinking water quality parameters set by WHO are every now and again damaged. Human exercises like uncalled for transfer of civil and mechanical effluents and aimless utilizations of agrochemicals in agribusiness are the principle factors adding to the crumbling of water quality. Microbial and substance contaminations are the primary elements mindful solely or in mix for different general medical issues. This paper presents a detailed layout of water quality in Bangladesh with unique accentuation on significant poisons, sources and causes of pollution. The information introduced in this paper are extracted from different surveys and reports distributed in national and global journals. Likewise reports discharged by the government and NGO associations are incorporated.BIBECHANA 15 (2018) 97-112

Quality Status

In the present study, an attempt has been made to investigate the drinking water quality status of various surface and ground water sources and the supplied water from two water filtration plants supplying drinking water to Doda town and its adjoining areas by using Arithmetic Water Quality Index (WQI) and geospatial mapping techniques. Doda is fluoride endemic district of Jammu and Kashmir State where groundwater fluoride concentration upto 7.0 mg/L is recorded. Water samples collected from about twenty two drinking water sources from two blocks of Doda district (Bhagwah and Doda blocks) were analyzed at pre-determined locations marked using handheld GPS(Montana 650). These locations formed the attribute database for the study based on which fluoride distribution maps have been derived and integrated with Arithmetic WQI through Inverse distance weighted (IDW) interpolation technique. Prepared thematic maps have confirmed the vulnerability of the drinking water sources and water supply systems in the study area, thus, posing a serious public health concern. Based on the WQI, water quality status of Beoli filtration plant (WQI=43.26) falls under the category of good water whereas that of Moochan filtration plant (WQI=157.41) has been classified as unfit for drinking. The geochemical evolution of the water studied using Piper’s diagram has shown mixed type of hydrochemical facies. Coefficient of correlation(r) between different parameters has indicated significant correlation between several parameters.  The study urges the concerned government authorities to make provisions for providing safe drinking water to public which is free of turbidity and low in fluoride concentration.

Associations between water sources, socio-demographic characteristics and household drinking water quality are described in a representative sample of six coastal districts of Ghana's Central Region. Thirty-six enumeration areas (EAs) were randomly chosen from a representative survey of 90 EAs in rural, semi-urban and urban residence strata. In each EA, 24 households were randomly chosen for water quality sampling and socio-demographic interview. Escherichia coli per 100 ml H2O was quantified using the IDEXX Colilert® system and multi-stage regression models estimated cross-sectional associations between water sources, sanitation and socio-demographic factors. Almost three quarters, 74%, of the households have >2 E. coli /100 ml H2O. Tap water has significantly lower E. coli levels compared with surface or rainwater and well water had the highest levels. Households with a water closet toilet have significantly lower E. coli compared with those using pit latrines or no toilets. Household size is positively associated, and a possessions index is negatively associated, with E. coli. Variations in community and household socio-demographic and behavioural factors are key determinants of drinking water quality. These factors should be included in planning health education associated with investments in water systems.

Abstract Water is an indispensable commodity for the survival of all living beings and for their well-being. The objective of this work is to evaluate the level of pollution of different drinking water sources consumed and its link with health in Pelengana commune, Mali. Samples of water were taken from various sources, namely, hand pumps, boreholes, dug wells, and shallow wells for physical, chemical, heavy metals, and bacteriological analyses, using American Public Health Association (APHA) Standard Techniques. Results revealed that the nitrate-nitrogen (NO3−N) values of the water samples from the different water sources had concentrations exceeding the United States Environmental Protection Agency's (US-EPA) regulation of 10 mg/L, as well as World Health Organization Guideline for Drinking Water Quality (WHO GDWQ) (11 mg/L). The same applies to heavy metals such as Cd, Pb, and Fe, in which, concentrations exceed their allowable limits in certain locations. Moreover, apart from water samples from some different boreholes, total coliform, and Escherichia coli have been detected in all selected water sources, which indicates fecal contamination. In all, there is a pressing need to stop the consumption of drinking water from contaminated sources and to effect appropriate treatment.

Public awareness about safe drinking water plays a significant role in household choices for drinking water sources and the prevention measures of water contamination. The present study was aimed to explore the awareness of households about groundwater quality and investigate the incidence of waterborne diseases in comparison with urban and rural households. Primary data were collected from 600 households by using the stratified random sampling technique. To analyze the outcomes descriptive and graphical approaches were used, however, to check the association between water sources and waterborne diseases bi-variate techniques were employed. It was found that the households belonging to urban localities were more aware about health risks associated with drinking water quality. Outcomes disclosed that on an average 48.8% of the household’s get affected from drinking water quality and face waterborne diseases, however, the incidence were greater (49.7%) in rural households compared to (48.0%) urban households. Findings also revealed that on an average 58.8% of the households suffered from belly pain and stomach problems and its incidence were 60.4% and 57.4% in rural and urban areas, respectively. Results disclosed that household’s income and medical expenditures were significantly associated with drinking water facility. It is suggested that the awareness about water quality should be disseminated among households in order to reduce the incidence of waterborne diseases.
