Water quality analysis is essential in assessing the suitability of different water sources used for various purposes, including industrial and domestic uses. This study was therefore aimed at determining the physicochemical and bacteriological quality of water samples from different storage facilities in a tertiary institution in Port Harcourt, Rivers State, Nigeria. The study involved eighty (80) water samples obtained from water storage tanks situated at 16 locations within the premises of the institution, to ascertain the physicochemical property, presence and population of different bacterial groups influencing the quality of these water sources. In-situ and ex-situ physicochemical analyses as well as bacteriological investigations were carried out on all samples, using standard laboratory procedures. Results of physicochemical analysis showed that the pH ranged from 4.15±0.14 to 7.16±0.08; conductivity, from 50.55±0.49 (µs/cm) to 364.00±2.83; salinity, from 0.02±0 (ppt) to 0.18±0; temperature, from 27oC to 28oC; Chloride, from 1.03±0.06 (mg/l) to 10.80±0.79; total alkalinity, from 4.00±0 (mg/l) to 11.00±1.41; Dissolved oxygen from 3.04±.020 to 7.36±0.08 (Mg/l) and BOD ranged from 0.81±0 to 4.23±0.09 (Mg/l). Results for bacterial population showed total heterotrophic bacteria ranging from 1.03±1.19 x 103   CFU/ml in water from reservoir tanks at the Faculty of Engineering, to 5.89±2.59 x 103   CFU/ml at Road A Block B; total coliform count ranged from 0 CFU/ml in most samples, to 10.00±2.36 x 102 CFU/ml in Block B reservoir tanks. Water reservoirs in clinic area recorded the highest Salmonella/Shigella counts (1.00±0.23 x 101   CFU/ml) with other stations having zero counts. Hall F (Hostel Ext) on the other hand had the highest counts for Vibrio (2.20±3.01 x 101 CFU/ml). The phenotypic characterization identified Citrobacter spp. as the most occurring (27.27%) bacterial isolate in the study, followed by Alcaligenes faecalis and Klebsiella spp. (18.18% each). Enterobacter spp., Edwardsiella spp., Erwinia psidii, Acinetobacter spp., Pseudomonas spp., Providentia spp. and Salmonella spp. all appeared as the least occurring, having a percentage of 4.55%, each. Tatumella spp. on the other hand had a percentage occurrence of 9.09%. This study has buttressed the need for increased water hygiene of reservoir tanks as well as water sources in these locations.

Compartment Bag Test

Abstract The aim of this study was to assess the bacteriological quality of water sources in the two rural areas of Uganda using the compartment bag test (CBT). In total, 200 water samples were collected from 69 different water sources and processed within 6 h of collection. Positive and negative controls were processed each day together with water samples. Physical parameters were measured in situ. Descriptive statistics were used to generate mean, minimum, maximum, standard deviations and percentages. The results indicated that 29% of the water sources met the National Standards and World Health Organization (WHO) Guidelines for drinking water. Sixty percent of the borehole, 44% of gravitational flow taps and 14% of roof rain water met the required standards. Of the open water sources, 75% of the rivers, 50% of open channels and 43% of unprotected dug wells plus 25% of protected springs and 9% of gravitational flow schemes had most probable number counts >100 Escherichia coli/100 mL of water. Most of the water sources in the study areas were not fit for human consumption without prior treatment. The CBT was found to be robust and easy to use in all field situations. The mean physical parameters of water sources were within the acceptable limits.

From August to September 2014 a water quality study was conducted on five popular public Danube beaches in Vojvodina, Serbia. To assess the safety of Danube water for bathing, physical, chemical, bacteriological tests were performed. While many parameters for monitoring the quality of water are regulated by law, there are neither national nor international legislations addressing the presence of viruses in recreational waters. In this study, we performed analyses that surpassed national requirements, and investigated if adenovirus, enterovirus or rotavirus genetic material was present in samples of recreational water collected for quality monitoring. Of 90 water samples obtained during the study, enterovirus material was not found in any sample, but adenovirus and rotavirus genetic materials were respectively detected in 60 and 31 samples. Statistical analyses showed a significant correlation between adenovirus DNA and total coliforms in the water. Even when water samples were adequate for recreational use, adenoviruses were detected in 75% (57/76) of such samples. Our results indicate that implementation of viral indicators in recreational water might be helpful to better assess public health safety. This might be particularly relevant in areas where urban wastewater treatment is insufficient and surface waters affected by wastewater are used for recreation.

Introduction: Safe water is a precondition for health and development and is a basic human right, yet it is still denied to hundreds of millions of people throughout the developing world. Water-related diseases caused by insufficient safe water supplies, coupled with poor sanitation and hygiene, cause 3.4 million deaths a year, mostly in children. Methodology: The present study was conducted on 1,317 drinking water samples from various water sources in Amritsar district in northern India. All the samples were analyzed to assess bacteriological quality of water for presumptive coliform count by the multiple tube test. Results: A total of 42.9% (565/1,317) samples from various sources were found to be unfit for human consumption. Of the total 565 unsatisfactory samples, 253 were from submersible pumps, 197 were from taps of piped supply (domestic/public), 79 were from hand pumps, and 36 were from various other sources A significantly high level of contamination was observed in samples collected from submersible pumps (47.6%) and water tanks (47.3%), as these sources of water are more exposed and liable to contamination. Conclusions: Despite continuous efforts by the government, civil society, and the international community, over a billion people still do not have access to improved water resources. Bacteriological assessment of all sources of drinking should be planned and conducted on regular basis to prevent waterborne dissemination of diseases.

The Impact

This paper presents the assessment of the impact of coal ash and slag from the ?Maljevac? dump on the quality of water of Paleski Creek, Montenegro. The obtained results confirm the negative influence of surface and groundwater from the dump on the water from the Paleski Creek. The results obtained by testing of the water samples, collected from Paleski Creek upstream of the dump, indicate that the water is qualified to be used for drinking, after simple physical treatment and disinfection. The results obtained for the water samples collected from the Paleski creek downstream from the dump indicate that the water could be safe for drinking only after the treatment that requires an intensive physical, chemical and biological processing, including some extended treatment.

Biodegradable Dissolved Organic Carbon

Total organic carbon (TOC) present in surface water consists of different fractions like dissolved organic carbon (DOC) or biodegradable dissolved organic carbon (BDOC). BDOC may have an impact on the bacteriological quality of water as it can be a source of carbon and energy for microorganisms. It is important to consider this parameter in case of the distribution of drinking water. The aim of this research was to compare the qualities of chosen surface water in Poland and Germany in terms of concentration of total organic carbon and its fractions. The samples were taken from the reservoir in Poland and Rhine River in Germany. The first one is a source of drinking water for humans. The research showed that, considering the analyzed compounds, the water from the river has better quality.
