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.

Background: The present study was carried out to assess the antimicrobial effect of honey on bacterial isolates from sachet water sold within Eligbolo Community in Port Harcourt, Nigeria. Methodology: Five brands of sachet water commonly consumed by the people living in Eligbolo Community of Port Harcourt, Nigeria were purchased from different Vendors in the community. Nutrient and MacConkey agar plates were used for culturing of water samples using spread plate method. Ten-fold serial dilution and Most Probable Number (MPN) were among the methods used and the samples analyzed were according to standard procedures. Natural honey purchased from Ogbokolo in Benue State, Nigeria was used for susceptibility testing. Quality control, ant inhibition and water test methods were performed using the honey to confirm its originality before use. Antimicrobial sensitivity testing was done using the agar well diffusion method. Results: Results obtained showed the bacterial isolated from the 5 sachet brands of water. These include Bacillus species 5 (62.5%), Enterococcus faecalis 1 (12.5%), Staphylococcus epidermidis 1 (12.5%), and Escherichia coli 1 (12.5%). All of the 5 sachet water samples analyzed failed to meet the WHO drinking water standard of zero coliform per 100 ml making them unsuitable for human consumption. Faecal coliform was isolated from sample C indicating faecal contamination of the drinking water. The sensitivity of the isolates to the honey sample showed higher zone of inhibition compared to the standard antibiotic used as control. Staphylococcus epidermidis showed the highest zone of inhibition (39 mm), followed by Escherichia coli (37 mm), Bacillus species (35 mm) and Enterococcus faecalis (32 mm) respectively. Conclusion: The results revealed that honey has a broad antimicrobial spectrum against Gram positive and Gram negative bacteria and could provide alternative agent to overcome the problem of increasingly bacteria resistance to synthetic antimicrobial agents. It is therefore, recommended that further work should be encouraged for the extraction of the crude components of honey and their use for antibiotic production.

Packaged water, most especially sachet and bottled water, is one of the major sources of drinking water in Nigeria, especially for commuters, whose major way of quenching thirst is to buy from road side vendors and previous studies has shown that packaged water does not always measure up to standard. Aim: Investigations were done to determine adherence to physiochemical, microbiological standards. Antibiotic susceptibility profile and plasmid profiling of enumerated bacteria using disc diffusion method were carried out on vended packaged water samples. Location of Study: Eleven brands of sachet water and seven brands of bottled water samples vended in Akure, Ondo State were randomly selected. Methodology: Physiochemical analysis was carried out and the parameters were checked in line with standard organization of Nigeria (SON) specifications. Isolation of bacteria was carried out using standard procedures and isolates were identified by various biochemical tests.   Plasmid analysis and curing was conducted following standard protocols Results: Total bacterial counts of sachet water brands ranged from 0.2 × 102 to 4.5 × 102 CFU/ml while that of bottled water brands ranged from 0.1 × 102 to 4.2 × 102 CFU/ml. Bacillus subtilis, Corynebacterium diphtheriae, Enterobacter aerogenes, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Staphylococcus aureus, S. epidermidis and Shigella dysentariae.  Streptococcus pneumoniae was isolated from the samples. Conclusion: Most packaged water (Bottled water, sachet water) samples are improperly handled and produced, which could serve as a source for spread of antibiotic-resistant potential pathogens, a risk to public health. better surveillance should be done on packaged water sale and production, public health education is encouraged for safety of residents in the Metropolis.

Aeromonas hydrophila, a potential pathogen associated with cases of human diarrhea, was enumerated using a rinse method on broiler carcasses and in processing water at selected locations in a commercial processing plant. A. hydrophila was detected on 98% of all carcasses tested, and 92% of all chill water samples; scald and rinse water samples were negative for this organism. Mean numbers on carcasses ranged for 28 CFU/ml of rinse fluid, detected immediately after the chiller, to 580 CFU/ml of rinse fluid at the post-evisceration stage. Water chilling and washing resulted in a significant reduction in A. hydrophila numbers on carcasses, while refrigerated storage (48 h) resulted in a significant increase. Data suggest that isolates recovered from carcasses may likely have been of intestinal origin and that the evisceration step was a probable cause of contamination. A. hydrophila levels on carcasses and processing waters showed no correlation to other bacteriological parameters which might be used in a process evaluation program.

In developing nations of the world 80% of all diseases and over 30% of death are related to drinking water. Drinking water may become contaminated during collection, handling, storage and use. Since the introduction of factory based water, their consumptions have increased severely in Liberia. Therefore, it is essential to investigate the physiochemical and bacteriological parameters of sachet water brands sold in Central Monrovia in order to ascertain whether they conform to recommended standards of portable drinking-water by the World Health Organization (WHO). This study made used of random sampling. Six samples of seven brands of sachet water were purchased randomly from provision shops. The samples were transported to the National Standards Laboratory for physiochemical and bacteriological analyses. Physiochemical parameters such as calcium, fluoride, iron, lead, turbidity and pH were checked, while Total Viable Count, coliform, and Escherichia were checked as bacteriological parameters. The calcium level of the samples ranged from 4.60 – 17.8 Mg/L. All the samples had 0.00 Mg/L of fluoride. The iron level of the samples ranged from 0.11 – 0.39 Mg/L. The lead level of the samples ranged from 0.21 – 0.36 Mg/L. The pH range of the samples was from 7.00 – 7.01. The turbidity of the samples ranged from 0.00 – 3.74 NTU. Six of the samples showed to have 0.00 NTU for turbidity. Only sample 6 had value for turbidity. The level of turbidity measured 3.47 NTU. Sample 1, 2, 5 and 7 had no trace of viable count, coliform and Escherichia while sample 3, 4 and 6 show traces of viable count, coliform and Escherichia. Samples with Total Viable Count far above 0 Cfu/mL are considered unfit for portability. There were coliform and Escherichia detected in some samples, thereby making these samples not palatable. All of the samples had concentration of calcium. All of the samples had pH and fluoride that are in range with the reference standards of the World Health Organization (WHO) and Ministry of Health (MOH). All of the samples had lead and iron that were out of range of the reference standards. All of the samples showed a turbidity of 0.00 NTU except sample 3 which had turbidity of 3.74 NTU.

Adequate supply of potable water is a major challenge in most leper colony with emphasis often placed on water needs of “normal” people but little concern on the safe water source for the physically challenged and vulnerable lepers with limited mobility who cannot search for other sources of water outside designated colony. This study was designed to investigate the quality of water sources within a Nigerian leper colony. Periodic characterization of groundwater and rainwater samples was conducted using American Public Health Association (APHA) methods to determine physico-chemical parameters; appearance, odour, colour, taste, chloride, pH, sulphate, copper, zinc, iron, nitrate and bacteriological parameters; coliform organism and Escherichia coli (E-coli) against the world health organization (WHO) drinking water standard. Water samples were clear and odourless. Most of the parameters tested from both sources; groundwater and rainwater were within the recommended standard. Results from short term water quality parameters taken from 2010-2012 were relatively within the same range while the long-term decadal water quality parameters showed slight variation compared to the short term. Heavy metals showed remarkable variation in 2019 while bacteriological parameters from both water sources were above the permissible threshold. For potable use, water sources require adequate treatment. Boiling or disinfection is recommended until water samples have been retested to ascertain that contamination has been eliminated. In addition, home water-treatment through the use of filters, solar disinfection, or flocculants should be provided to make the water safe.

Abstract This study analyses the quality of sachet water consumed by university students in Metropolitan Kumasi, Ghana. Thirty sachet water samples from ten different brands were tested for their physical and bacteriological quality using meters and titrimetric method and most probable number method, respectively. Overall, one half of the sachet water samples were highly contaminated with total and faecal coliform. While the mean total coliform/100 mL concentration of ANG, NOV, IM, PD and DKN were 9.15 × 105, 2.35 × 106, 9.15 × 105, 4.15 × 105 and 9.15 × 105 respectively, we recorded faecal coliform counts of 2.3 × 105, 4.15 × 105, 2.3 × 105, 2.3 × 105 and 2.3 × 105, respectively for ANG, NOV, IM, PD and DKN. Moreover, samples from DKN brand showed Escherichia coli count of 4.0 × 104. The conductivity ranged from 2.24 μS/cm to 43.60 μS/cm while the mean total alkalinity of all samples ranged from 33.33 mg/L to 120 mg/L. The coliform contamination levels of the water samples violated the guidelines and standards of WHO for drinking water quality. Ghanaian regulatory agencies should intensify the monitoring and surveillance activities to ensure compliance with strict hygienic measures by sachet water producers.

Physicochemical and Bacteriological Parameters of Borehole and Hand dug well water of Michika town in Michika Local Government Area of Adamawa State, Nigeria and environs were assessed to determine their suitability or otherwise for drinking and domestic purposes. Ten (10) water samples, five each from boreholes and hand-dug wells, from five selected areas in Michika town, were collected during the months of January and February 2018. The water samples which are extensively used for drinking and other domestic purposes, were randomly collected and the results were compared with WHO and NAFDAC standards guidelines for drinking water. These samples were analyzed for their physicochemical characteristics (pH, temperature, electrical conductivity, TDS, Turbidity, hardness), heavy metals, Escherichia coli (E. coli) and coliform counts. The results of the investigation revealed that the physicochemical and bacteriological parameters falls within the maximum permissible limits of NAFDAC and WHO guidelines for drinking water. The physicochemical concentrations were higher in borehole water than in hand dug well water; Lead and Cadmium were not detected in all the samples. All the water samples were free from feacal contamination except in Barikin Dlaka hand dug well which contained 0.05 ± 0.001 MPN/100 ml total coliform count which is below the WHO/NAFDAC maximum permissible levels. The suitability of water for domestic and drinking purposes indicated that the water samples were within the standards prescribed for potable water. However, there is need for routine checks to ascertain the suitability or otherwise of these water sources so as to forestall outbreak of water born diseases.
