This study was done to determine the quality of water from hand-dug wells in Kuje, Federal Capital Territory Abuja Nigeria. The study area lies between latitudes 080 53’ 24’’N and 080 53’ 47’’N and longitude 070 14’ 24’’E and 070 14’ 35’’E. Water from twenty wells were randomly sampled. The physical properties investigated are pH, temperature, total dissolved solid (TDS) and electrical conductivity. The chemical analysis involved determination of the concentration of anions (SO42-, HCO3-, Fl-, CO3-, Cl-, NO3) and cations (Ca2+, Mg+, Na+,K+, Zn+, Fe2+, Cu2+. A piper diagram based on the relative percentages of the ions was plotted for classification according to hydrogeochemical facies of each water sample based on their dominant ions. The Piper diagram indicated Ca2+ and HCO3- as the dominant ions and therefore it is Ca−HCO3 water type. The physical properties of the water were found to be good based on World Health Organization (WHO) guidelines and National Drinking Water Quality Standard (NDWQS) and therefore water in the study area is safe for human consumption.KEYWORDS: groundwater, hydrochemical facies, anion, cation, piper diagram

Nitrate groundwater contamination is of major interest all over the world. This problem arises in agricultural regions across Morocco. An excess amount of nitrate causes a serious problem in urban water networks and human health. Because of these health risks, considerable attention has been paid to find effective treatment processes to reduce nitrate concentrations to safe levels. The World Health Organization has set an acceptable level for nitrate in drinking water at 50 mg/L. The aim of this study is to reduce the nitrate concentration from groundwater using two membrane processes: Electrodialysis (ED) and Nanofiltration (NF). Efficiencies of these two technologies are compared in respect to nitrate ions removal, cost process and final quality of water. The results of technologies show that, for electrodialysis standards level can be achieved for a demineralization rate of 15% and the physico-chemical quality of the produced water is satisfactory. For nanofiltration we obtain a nitrate removal of 90% but the produced water is very de-mineralized and must be remineralized.

The key to provide microbiologically safe drinking-water lies in understanding the various mechanisms by which water gets contaminated. This study assessed the risk of contamination and microbiological and chemical quality of water from protected dug wells in five selected Panchayats in Kollam district, Kerala state, southern India. Sanitary inspection was conducted for 70 protected dug wells using World Health Organization established procedures for risk of contamination scoring. Microbiological and chemical analysis of water samples was done. The areas with higher incidence of hepatitis A had a higher proportion of wells with high risk of contamination scores (p = 0.006). High risk of contamination scores for wells were associated with higher incidence of fecal pollution (odds ratio 11.80; 95% confidence interval 1.87–74.86). The study highlighted the need to make the wells safe in this area, for control of waterborne diseases.

Hydrochemical data of groundwater samples obtained from the mudstones, sandstones, and siltstones aquifer units that underlie the study area have been characterized. The aim of this study was to assess the suitability of groundwater for drinking, domestic, and agricultural purposes. The physico-chemical parameters were initially compared with the World Health Organization (WHO) standards for potable water. They were further subjected to various hydrochemical techniques to assess the overall water quality for drinking purposes. Conventional methods of assessing irrigation water suitability were also adopted. The results indicate that, with the exception of HCO3− characterized as unsuitable for drinking water, most of the parameters are within the WHO permissible limits and are thus characterized as suitable for drinking water. A few samples however show slight deviation. The results also show that the abundance of major cations in groundwater is in the order: Na+ > Ca2+ > Mg2+ > K+. However, the abundance of the major anions is in the order: HCO3− > Cl− > SO42−. Na-HCO3 is thus inferred as the dominant water type in the area. Analyses of the overall Water Quality Index (WQI) and irrigation water assessment indices suggest that groundwater in the area is generally suitable for drinking, domestic, and irrigation purposes.

This study shows the effect s of solid waste dumpsite on ground water quality in Farin-gida, Kaduna State Nigeria. Water samples were collected from six (6) different wells in three(3) strategic areas that have major dumpsites in Farin-gida. These samples were collected in November from both bore holes and hand dug wells within (0-50 meters) to the dumpsite. The following physico-chemical properties of well water was tested for, in the laboratory thus; Total Dissolve Solid, Total Alkalinity, Fluoride, PH, Turbidity and Electrical Conductivity. The results obtained as shown in table 1,2 and 3 respectively indicate that all the wells have varying levels of physico-chemical concentration that is different from the standard as recommended by World Health Organization (WHO) and Nigeria Standard for Drinking Water Quality (NSDWQ), which implies that the water from the study areas are not safe for drinking. Hence, should be treated.

Water is one of the vital needs of all living beings for daily activities like drinking, washing, bathing etc. It is the most important factor in shaping the land and regulating the climate. The quality of water for drinking and other activities if does not satisfy the standard conditions of physical, chemical and biological characteristics as prescribed it then becomes ineffective. The quality of water is usually described according to its. Hence it becomes necessary to find the suitability of water for various purposes like drinking, irrigation and Industrial purposes. Rapid industrialization and use of chemical fertilizers and pesticides in agricultural lands, discharge of voluminous municipal and industrial waste waters are causing deterioration of water quality vis-à-vis depleting of aquatic biota. This ultimately causes massive pollution not only to the rivers, ponds and wells but also drastically degrade the quality of groundwater. Research have been undertaken to use such type of waste water in different construction purposes. It is absolutely true that demand of fresh water by the construction sector is expected to increase due to high increase in the growth of construction activities in India (Dhanraj, 2017). Highly polluted Sutlej river in Punjab has been a constant encouragement to the environmentalists about reusing the contaminated water of the river. A total of 14 water samples from different point sources of pollution were collected and tested for physico-chemical parameters (pH, temperature, DO, BOD, COD, TSS, TDS), metals (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) and microbiological parameter using World Health Organization (WHO) and the Bureau of Indian Standards (BIS) standards to justify how the strength of concrete goes on varying with respect to using the river water directly. An attempt was made to justify the use of wastewater directly in preparing concrete for construction purposes by testing concrete cubes prepared by the untreated water and comparing them with the strength of standard cubes.

The industrial augmentation and unguided anthropogenic activities contaminate water sources in most parts of the world especially in developing countries like Pakistan. High concentration of pollutants in groundwater affects human, soil, and crop health badly. The present study was conducted to investigate groundwater quality for drinking and irrigation purposes in an industrial zone of Pakistan. A GIS tool was used to investigate the spatial distribution of different physico-chemical parameters. In this study, the average results exceeding World Health Organization (WHO) and National Environmental Quality Standards (NEQS) were found for pH 7.84, total dissolved solids (TDS) 1492 mg/L, phosphate 0.51 mg/L, dissolved oxygen (DO) 9.92% saturation, F-coli 6.48 colonies/100 mL, Na+ 366 mg/L, HCO3− 771 mg/L, sulfate 251 mg/L, chlorides 427 mg/L, total hardness (as CaCO3) 292 mg/L, electrical conductivity (EC) 2408 μS/cm, iron (Fe) 0.48 mg/L, chrome (Cr) 0.50 mg/L, arsenic (As) 0.04 mg/L, total phosphorus (TP) 0.17 mg/L, sodium adsorption ratio (SAR) 9.76 (in meq/L), residual sodium carbonate (RSC) 9.28 meq/L, % ion balance 14.4 (in meq/L), percentage sodium ion (% Na+) concentration 58.9 meq/L, and water quality index (WQI) 69.0. The trend of cations and anions were (in meq/L) Na > Mg > Ca > K and HCO3 > Cl > CO3 > SO4 respectively. Although the results of the present study showed poor conditions of the groundwater for drinking as WQI but and irrigation purposes as SAR, it needs to improve some more conditions for the provision of safe drinking water and irrigation water quality.

Abstract Njoro sub-county in Kenya suffers from constant water shortages causing the residents to rely on both improved and unimproved water sources in the area. The households in the sub-county also use different household storage containers to store drinking water in times when water is not readily available. This study was therefore undertaken to assess selective physico-chemical parameters of water used by the population for drinking purposes using standard assessment methods. A total of 372 water source samples and 162 storage container water samples were tested over a period of three months. Turbidity (0.70–273.85 NTU), iron (0.7–2.10 mg/L), fluoride (0.15–4.01 mg/L), manganese (0.01–0.37 mg/L), and nitrate (0.09–27.90 mg/L) levels in water samples were generally higher than the Kenya Bureau of Standards (KEBS) and/or the World Health Organization (WHO) water quality recommendations for safe drinkable water. The results from this study support the need for continuous monitoring and treating drinking water at the points of collection and of consumption to minimize the long-term health effects on communities consuming this water.

In this study, we aimed to assess the geographic inequalities in access to improved water and sanitation facilities among Nepalese households. We conducted this study based on cross-sectional data obtained from Nepal Demographic and Health Surveys. The quality of water sources and sanitation were defined by World Health Organization (WHO) guidelines. The geographic categories used in the analyses included developmental region, ecological zone, and urbanicity. Percentages of households having access to improved toilet (5.6% in 1996 vs. 40.5% in 2016) and water (19.3% in 1996 vs. 27% in 2016) facilities has been increasing steadily since 1996 with a great proportion of the households still lacking access to these services. The number of households sharing the same toilet and traveling time to reach water sources have also decreased at the same time. Households in Far Western and Mountains had the lowest odds of having access to improved toilet and water facilities. Noticeable progress has been achieved in improving WASH (water, sanitation, and hygiene) coverage at national level, however, it is uneven across developmental and ecological zones. Households in the Far Western and Mountain regions appeared to be the most geographically disadvantaged in terms of having access to improved water and sanitation facilities.

The drinking water quality was investigated in suspected parts of Perak state, Malaysia, to ensure the continuous supply of clean and safe drinking water for the public health protection. In this regard, a detailed physical and chemical analysis of drinking water samples was carried out in different residential and commercial areas of the state. A number of parameters such as pH, turbidity, conductivity, total suspended solids (TSS), total dissolved solids (TDS), and heavy metals such as Cu, Zn, Mg, Fe, Cd, Pb, Cr, As, Hg, and Sn were analysed for each water sample collected during winter and summer periods. The obtained values of each parameter were compared with the standard values set by the World Health Organization (WHO) and local standards such as National Drinking Water Quality Standard (NDWQS). The values of each parameter were found to be within the safe limits set by the WHO and NDWQS. Overall, the water from all the locations was found to be safe as drinking water. However, it is also important to investigate other potential water contaminations such as chemicals and microbial and radiological materials for a longer period of time, including human body fluids, in order to assess the overall water quality of Perak state.
