Water is an essential component of human living and crucial in metabolism, substrate transport across membranes, cellular homeostasis, temperature regulation, and circulatory function. Access to quality water is a critical concern of any society. However, water shortage remains the central problem of many households across the universe, prompting people to depend on water sources that are considered unhealthy for human consumption. The primary purpose of this study was to examine the bacteriological compositions of water sources in Kogi State based on seasonal disparities. Water samples were obtained from streams and hand-dug wells within the Ankpa and Obajana areas during the rainy and dry seasons. The analysis conducted on the samples revealed that the water sources were heavily contaminated with bacteria at both seasons.

Lack of access to safe and adequate domestic water supplies contributes to poverty levels through the economic costs of poor health and the high proportion of household expenditure on safe water supplies. Gwallameji, a community on the outskirts of Bauchi town has no access to municipal water supply from Bauchi town, groundwater water, mainly hand dug wells are used as domestic water sources. The quality of water available from these hand dug wells  in the community were determined by the physical, chemical and biological parameters of the water samples collected from domestic water points in the community. The results from the water samples were compared with World Health Organization (WHO) Standards for Drinking Water. High levels of Nitrate and Chromium above recommended levels from the standard were found in all water samples. Concentrations of Calcium highest value of 213mg/l and Magnesium a highest value of 22.02 mg/l at levels higher than recommended levels for drinking water were also obtained in all samples. It was recommended that restrictions on farming activities with use of fertilizers and location of latrines around domestic water sources should be enforced. Hand dug wells should be at a distance of at least 30m from soak away pits and pit latrines. Well lining and cover should be provided for all hand dug wells to reduce contamination of water from these sources. Increased and continued environmental interventions through public health education by community based health workers, awareness and sensitization campaigns should be carried out for improved household and community sanitation in the area.

Assessment of the efficacy of Water-Care in the treatment of water to safe health level was carried out on water samples from different water sources within six populated communities of Makurdi Metropolis. Thirty six (36) water samples were collected and treated with WaterCare based on the product manufacturer’s instructions. Treated water stored for 30 minutes and 24 hours were tested for coliforms using Multiple Tube Fermentation technique. Analysis of variance (ANOVA) was used with the Tukey Honestly Significant Difference (HSD) for multiple comparisons of the data variables. Most probable Number (MPN) of coliforms /100mL of sampled water ranged from 43 to >1,100cfu/100ml. Mean MPN of treated water for30 minutes and 24 hours interval was 37.7±33.0cfu/100ml and 16.17±14.8cfu/100ml respectively. Improved/deep sources such as boreholes show 3cfu/100ml and 0cfu/100ml respectively for 30 minutes and 24 hours treatment while unimproved/shallow sources such as wells show ≤120 cfu/100ml and ≤53 cfu/100ml respectively for 30 minutes and 24 hour interval. A significant difference between treated samples and the untreated was observed (F = 6.321, P = 0.005). Tukey multiple comparison test revealed that MPN index/100ml in the water samples was significantly lower (P =0.015, P =0.009) after treating for 30 minutes and 24 hour time interval respectively as compared to untreated water. But there was no significant difference between the 30 minute and 24 hour time interval (P =0.970). The study found that, drinking water sources in Makurdi Township were heavily contaminated, and that 30 minutes and 24 hours’ time interval was not a sufficient time for total elimination of bacteria contaminants after treatment with WaterCare. Future research should ascertain the actual treatment time for inactivation of all bacteria in water treated with WaterCare.

In the tropics, there are too few studies on isolation ofBlastocystissp. subtypes from water sources; in addition, there is also an absence of reported studies on the occurrence ofBlastocystissp. subtypes in water during different seasons. Therefore, this study was aimed to determine the occurrence ofBlastocystissp. subtypes in river water and other water sources that drained aboriginal vicinity of highly endemic intestinal parasitic infections during wet and dry seasons. Water samples were collected from six sampling points of Sungai Krau (K1–K6) and a point at Sungai Lompat (K7) and other water sources around the aboriginal villages. The water samples were collected during both seasons, wet and dry seasons. Filtration of the water samples were carried out using a flatbed membrane filtration system. The extracted DNA from concentrated water sediment was subjected to single round polymerase chain reaction and positive PCR products were subjected to sequencing. All samples were also subjected to filtration and cultured on membrane lactose glucuronide agar for the detection of faecal coliforms. During wet season,Blastocystissp. ST1, ST2 and ST3 were detected in river water samples.Blastocystissp. ST3 occurrence was sustained in the river water samples during dry season. HoweverBlastocystissp. ST1 and ST2 were absent during dry season. Water samples collected from various water sources showed contaminations ofBlastocystissp. ST1, ST2, ST3 and ST4, during wet season andBlastocystissp. ST1, ST3, ST8 and ST10 during dry season. Water collected from all river sampling points during both seasons showed growth ofEscherichia coli and Enterobacter aerogenes, indicating faecal contamination. In this study,Blastocystissp. ST3 is suggested as the most robust and resistant subtype able to survive in any adverse environmental condition. Restriction and control of human and animal faecal contaminations to the river and other water sources shall prevent the transmission ofBlastocystissp. to humans and animals in this aboriginal community.

A study of the water sources from Bibiani and its environs was conducted between November, 2009 and April, 2010 to determine whether contamination (of water sources) from (these parameters) physical, chemical and trace metal in Bibiani is as a result of mining or geochemicaland biochemical processes within the environment. This was done by collecting water samples from two streams, two rivers, three boreholes (BHs) and three hand dug wells (HDWs). These were analysed in the laboratory. Levels of Arsenic (As), Iron (Fe), Manganese (Mn), pH, TotalDissolved Solids (TDS), Electrical Conductivity (EC), Temperature, Alkalinity, Hardness, Phosphate (P) and Cyanide (CN) in water sources were determined. Mining related contaminants detected in water samples were As, CN, Mn and Fe. It was observed that surface water pH values were generally higher than that of groundwater samples. As concentrations in surface water samples were higher compared to that of groundwater samples. Also, CN concentration in ground water samples was higher than that of surface water. Ground water contained higher concentration of Mn than surface water; the opposite can be said of Fe concentration in surfacewater which was higher than that of ground water. The study also observed that pH, TDS, EC, total alkalinity, total hardness , Arsenic and total cyanide levels in the HDW and BH samples showed 100% compliance with the WHO and EPA limits while Mn and Fe levels indicated traces of non – compliance. Compared to WHO / EPA guidelines, few water sources had one or moretrace metal (Fe, As and Mn) levels outside acceptable limits for drinking. However, most of the levels were safe for human consumption.Keywords: Surface, gold mining, quality, degradation, Bibiani

Hepatitis E virus (HEV) is a common cause of water-borne acute hepatitis in areas with poor sanitation. In 2004 an outbreak of HEV infection affected around 2,000 people in Eastern Chad (Dar Sila). This paper describes the decrease in the incidence of acute jaundice syndrome (AJS) from 2004 until 2009 when a mean incidence of 0.48 cases/1,000 people/year was recorded in the region. Outbreaks of AJS were identified in some of the camps in 2007 and 2008. Moreover, water samples from drinking water sources were screened for human adenoviruses considered as viral indicators and for hepatitis A virus and HEV. Screening of faecal samples from donkeys for HEV gave negative results. Some of the samples were also analysed for faecal coliforms showing values before disinfection treatment between 3 and >50 colony forming units per 100 mL. All water samples tested were negative for HEV and HAV; however, the presence of low levels of human adenoviruses in 4 out of 16 samples analysed indicates possible human faecal contamination of groundwater. Consequently, breakdowns in the treatment of drinking water and/or increased excretion of hepatitis viruses, which could be related to the arrival of a new population, could spread future outbreaks through drinking water.

Water remains the most abundant and critical commodity for guaranteeing the continuity of human lives on earth. Ensuring cleanliness of water for human consumption is of paramount importance. The 222Rn concentration has been assessed in drinking water samples collected from various water resources used by communities around Sokoto Cement Company, with the view of assessing the radiological risk, if any, to human health. The sources of collected water samples were hand pumps and hand dug wells and water seepages. Determination of radon concentration was conducted using liquid scintillation counter (Model: Tri-Carb-LSA1000) following standard procedures. The overall mean value of 222Rn concentration was found to be 34±3.7 Bq/L The resulting mean annual effective doses due to inhalation of radon in the water samples was 41 μSvy-1, while ingestion for adults, children and infants were 248±27 μSvy-1, 372±40 μSvy-1 and 434±47 μSvy-1 respectively. These values are above the recommended benchmarks prescribed by UNSCEAR, WHO, European commission and USEPA guiding the utilization of water for drinking and domestic purposes. This indicates that the water resources around the cement company are not safe for drinking and domestic purposes from the radiological point of view.

Abstract IntroductionWater should comply with standard/regulatory physio-chemical and biological parameters to ensure that it is safe for domestic use. We therefore sought to assess the physico-chemical and biological quality of groundwater sources in Kadama subcounty, Kibuku district, Eastern Uganda. MethodsA cross-sectional quantitative study was conducted. We collected water samples from twenty-three functional water sources. We assessed the turbidity, pH and presence of Escherichia coli (E. coli) using the turbidity meter, pH meter and membrane filtration technique, respectively. Furthermore, physical sanitary inspection of the water sources was done using a standard pretested observational checklist to assess existing risk factors.ResultsThe majority, 69.5% of the water sources included in the study were boreholes, with about 43.5% of them from Nandere parish. Majority of the water sources 86.9% (20/23) had clogged/blocked drainage channels, about a third of water sources 60.9% (14/23) did not have fences/protection around them and majority of the water sources, 82.6% (19/23) had stagnated apron. Some water sources 8.7% (2/23) had open defecation around them. The water samples had a mean pH of 6.87 (SD 0.920) with 4.4% acidic, 86.9% normal/acceptable pH level and 8.6% in alkaline state. About two-thirds (65.3%) of these water sources had turbidity levels less than 5 NTUs. In addition, boreholes had a better turbidity score of 81.2% (13/16) compared to the water wells 71.4% (5/7). About half, 43.5% of the water sources were above the WHO recommended range of zero coliforms. ConclusionsSome ground water sources had sanitary risk factors and significant levels of E. coli which makes them unfit for human consumption, though they can be used for other domestic purposes including washing clothes. This calls for urgent need to keep surrounding water sources clean and continuously disinfect drinking water from groundwater sources before human consumption.

The study found that, drinking water sources in Makurdi Township were heavily contaminated, and that 30 minutes and 24 hours’ time interval was not a sufficient time for total elimination of bacteria contaminants after treatment with WaterCare. Future research should ascertain the actual treatment time for inactivation of all bacteria in water treated with WaterCare.

Water from ten hand-dug wells from Assin North Municipality in Ghana were analysed at Ghana Water Company Limited Quality Assurance Laboratory, Ho in Ghana for various physico-chemical parameters. The analyses used standard methods with chemicals of AR grade; pH was measured with the Horiba Compact B-122 and Inolab 7300 Conductivity/TDS portable meter. Colour, turbidity, aluminium, copper, sulphate and total iron were analysed by spectrophotometry using Hach DR/2500 following standard methods. Flame photometer was used for determination of metal ions Na+, K+ and Ca2+. Silver nitrate method was used to estimate chloride, sulphate was determined by turbidimetric method. Total hardness was calculated by complexometric titration using EDTA. The results of the analyses show pH 6.0 to 7.2 with a mean of 6.5, conductivity from 300 to 800 μS/cm, TDS range from 90 to 400 mg/l. Piper Trilinear diagram revealed three main water types - calcium bicarbonate (Ca+Mg-HCO3) possibly sourced from Ca-plagioclase, biotite and amphibole; sodium chloride (Na-Cl) from Na-plagioclase, muscovite and chlorite; and mixed water types which may be due to the combined effect of Birimian metasedimentary rocks, Belt granitoid and pegmatites that released into the water through cation exchange and accounted for Na+ in the Na-Cl water type. Chloride in a few hand-dug wells may be linked to mineralogy crystallised from marine deposited sediments and infiltration of rainwater along fractures in the rocks. Hence most of the water samples have Na/Cl ratios<0.86. The rainwater in the area with weak acidity possibly infiltrated into the soil to cause appreciable concentration of HCO3- in the studied water. The total coliform values in water were less harmful as there was no faecal coliforms, though total microbial values in hand-dug wells X4 and X10 with total coliform values of 2.2 and 5.1 MPN/100ml respectively exceed the WHO guidelines. Hand-dug wells X4 and X6 in the study probably ended in aquifers in the weathered zone with the rest of the wells in fresh fractured horizons of the granitoids. Na/Cl ratios>1 (for water samples X1, X7 and X8) might have been due to contamination from anthropogenic sources. Pearson correlation indicates strong and positive correlation of TDS<Mg< Na with conductivity. All the water samples were safe for human consumption.
