Water quality has become a serious issue to economic and social sustainable development, not only because of the imbalance between available scant water resource and dense population, but also the inefficiency of water resources regulation and management. This study is aimed at assessing the quality of borehole water at the study areas and to compare with standards, Water samples were collected from three stations (Mile 1 to 3) at nine points in oroworukwu area of Port Harcourt. Physicochemical parameters were analysed which includes pH, alkalinity, turbidity, temperature, salinity, total dissolved solid, conductivity, chloride, nitrate, and heavy metals. Bacterial analysis done included total coliform count, total fecal count and total heterotrophic bacteria. The results obtained showed a pH ranged of 4.8-5.9 which was below the permissible limit (6.8-7.8) of World Health Organization (WHO) and Nigeria Industrial Standard (NIS). All other physicochemical parameter results were within permissible limits. There were no bacteria detected in the water which indicated that the water was not contaminated. In any case there is a need to treat the water to raise the pH to the acceptable value of WHO and NIS.

Wastewater samples were collected from an oil industry at the point of discharge for a period of two years, from January 2018 – December 2019. The wastewater samples were analyzed for different physicochemical parameters such as temperature, turbidity, total dissolved solids (TDS), total suspended solids (TSS), conductivity, pH, alkalinity, salinity, total hydrocarbon content (THC), biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to examine their conformity to fulfill requirements as recommended by World Health Organization (WHO), Federal Ministry of Environment (FME) and Drinking Water Association (DWA). The results indicated that all the parameters in the discharged wastewater were within acceptable limits of the regulatory bodies. The field data showed that the investigated firm conformed to the law by carrying out proper procedures before discharging the effluents into the public drain and river. Therefore, the release of wastewater from the industry doesn't constitute a danger to the environment as well as aquatic organisms.

Water from boreholes and packaged commercial sachet water from different areas in a community in southern Nigeria was analyzed with membrane filtration for a snapshot of heterotrophic count and coliforms. Two boreholes out of the 20 analyzed had counts of over 500 Cfu/mL and 7 boreholes indicated the presence of coliforms. Sixteen samples out of 20 sachet water brands analyzed showed a regulatory product registration code, whereas 4 samples had no number or code indicating that they were not registered. The heterotrophic count of all sachet water was well within the limit for all samples analyzed, and coliform was detected in only two samples. The overall quality of borehole water in the community studied was rated D (65%), whereas the sachet water was rated C (90%) according to the World Health Organization (WHO) surveillance guidelines. Improvements in water quality structure in the community studied are required to help achieve WHO sustainable development goals on water sanitation. The etiology, virulence properties, epidemiology, and pathogenicity of bacteria associated with borehole and sachet water are also discussed.

Studies on physicochemical and microbial profiles of selected hotel swimming pools in Port Harcourt, Rivers State, Nigeria was carried out using standard methods. Six swimming pools of selected hotels within the Port Harcourt city that people use for recreational activity were selected for this study. The selection was done in such a way that all the zones within the city were considered. The hotels names were coded with alphabets for confidentiality. Each swimming pool was divided into up and down ends for this study. Average result obtained for both ends in each pool was taken as a sample value for each pool and was compared to World Health Organisation (WHO) standard for recreational water. Physicochemical results such as pH, alkalinity, calcium hardness, chlorine and residual chlorine of most of the studied pools were not within WHO standard. The microbial loads of the studied pools in terms of total coliform, faecal coliform and Escherichia coli were higher than WHO standard. There is no doubt that most of the studied hotel swimming pools fall short of WHO standard for recreational activity. This becomes important when the consequences of swimming in such pools to humans are considered. There is urgent need for the hotels hosting the studied swimming pools to adopt the important five keys to maintaining water quality in swimming pool, which include proper filtration, proper chlorination as well as adjustment of pH, total alkalinity and calcium hardness levels as stipulated by WHO standards. This study has shown the physicochemical and microbial profiles of selected hotel swimming pools in Port Harcourt, Rivers State, Nigeria.

The quality of harvested rainwater in Aule area of Akure, South western Nigeria was assessed in this study. Water samples were collected from 25 rain water storage tanks within the study area and a well was used as a control. The water samples were subjected to detailed laboratory analysis and the results obtained was compared with World Health Organization (WHO) standard for drinking water. The turbidity values ranged from 2.7 to 9.1 NTU for the harvested rainwater samples while the well water sample had a turbidity of 2.3 NTU. The conductivity values for the rainwater samples ranged from 101 to 1328 Ωs/cm. The conductivity value was lower in the well water (164 Ωs/cm) than in most of the harvested rain water samples. The pH of the harvested rainwater ranged from 6.1 to 7.4 with 36 % of the water samples having a pH less than the WHO minimum limit of 6.5. The pH of the well water sample was 7.4 and was within the WHO acceptable limits of 6.5 to 8.5. All the sampled rainwaters and well water had bacteria in them. The total bacterial content of the rain water samples ranged from 05 to 28 CFU/100 mL, while that of the well was 05 CFU/100 mL. The total coliform contents of the rainwater samples ranged from 03 to 18 CFU/100 mL, while that of the well was 02 CFU/ 100 mL. Based on the results obtained from this study, it is recommended that harvested rainwater be treated to kill contaminating microorganisms and to reduce the health risks associated with its consumption.

In the abattoir, large amount of water is being used in processing operations; and this produces huge amount of wastewater which empty into the surrounding water bodies. The cross-sectional study followed the conventional microbiological techniques of macroscopy, microscopy, isolation, and identification to assess the bacteriological and parasitological examination of water sources in selected abattoirs in Port Harcourt Metropolis, Rivers State, Nigeria. The result of microbial population showed Total Coliform ranging from 5 x 101cfu/ml – 2.80 x 102cfu/ml and Faecal Coliform bacteria of 2.80 x 101 cfu/ml -1.85 x 102 cfu/ml. Total Heterotrophic bacteria ranged from 7.8 x101cfu/ml to 4.2 x102cfu/ml. The mean microbial counts; 4.86 x101 cfu/ml Fecal Coliform, 9.65 x 101cfu/ml Total Coliform and 1.82 x 102cfu/ml Heterotrophic Count. The isolates identified were Klebsiella spp, Shigella spp., Salmonella typhymurium, E. coli, Proteus spp., Salmonella paratyphi, Vibrio cholera. Nkpor village abattoir recorded highest occurrence of bacteria isolate with a total of 50(22.03%) followed by Iwofe 48(21.15%). Water sample from ponds had a higher parasitic contamination while samples from the borehole were free from parasitic infestation. Water samples for parasitological assessment were filtered and examined for parasitic organism using standard methods. Four different parasites were identified in the study, they include Ascaris lumbricoides (32.5%), Entamoeba histolytica (22.5%), Giardia lamblia (17.5%) and the least Taenia spp (7.5%). Nkpor-village abattoir had the highest level of contamination with (30.0%) parasite occurrence, followed by Mgboshimini abattoir (15.0%). The use of unsafe water for meat processing by butchers, portends a serious public health risk to consumers who purchase the meat, from these abattoirs. Therefore, government should endeavour to make borehole water available to all the abattoirs in Port Harcourt.

In this study, health risk assessment of well water from twelve communities grouped into upland and riverine in Rivers State was carried out in several categories such as uses of water, skin infections and health assessment via questionnaire distribution. Malaria was recorded to be the most common disease related to water. Furthermore, water samples were collected and analysed for physiochemical, biochemical and pathological characteristics. The average pH was 7.52, an indication of neutrality. Several species of bacterial and fungal organisms were isolated and identified. The total heterotrophic bacteria (THB), total fungal and total coliform counts ranged from 14.0x104cfu/ml to 100.0x104cfu/ml, 3.2x103cfu/ml to 7.4x103cfu/ml and 4 cfu/100 ml to ≥2400 cfu/100 ml respectively. Morphological and biochemical observations revealed the presence of the following organisms: Aeromonas sp., Alcaligenes sp., Bacillus sp. Citrobacter sp. E. coli, Enterobacter sp, Klebsiella sp., Micrococcus sp., Proteus sp., Salmonella sp., Sarcina sp., Shigella sp., Staphylococcus sp., Streptococcus sp. and Vibrio sp. Staphylococcus sp. and Streptococcus sp. had the least percentage incidence of 8.3% while Vibrio sp had the most incidence of 100% in all the well water sampled. Well water is a source of pathogenic bacteria; hence, it is recommended that consistent water quality studies should be conducted on all the well water in the communities at least once in a year. Well water should also be treated before use to avoid the outbreak of water borne diseases.

The health and environmental risk associated with unlined open waste dumpsites are worrisome. This study, therefore, evaluated the leachate and its final fate on groundwater pollution at selected solid wastes dumpsites in Rivers State. Leachate samples collected near the dumpsites were analyzed to determine the physical and biochemical characteristics. The two studied dumpsites indicated that the computed TCB were 296.33±6.22 cfu/100 ml and 182.68±21.33 cfu/100 ml respectively which were within the permissible limits of 400cfu/100 ml specified by World Health Organization (WHO) and Federal Ministry of Environment (FMEnv); which suggest low quantities of disease-causing agents in the groundwater. The total heterotrophic bacteria (THB) were 21x104 cfu/ml and 17x104 cfu/ml. These high values of THB may not be an indication of contamination of groundwater but it indicates a gradual decline in raw water quality. The values of SO42-, PO43-, TDS, DO, BOD and COD at the dumpsites were 196.52±6.26 mg/l and 9.12±0.59 mg/l, 139.23±3.19 mg/l and 3.81±0.68 mg/l, 5952.23±72.52 mg/l and 12663.33±490.95 mg/l;1.51±0.42. mg/l and 2.02±0.16 mg/l; 31.22±4.12 mg/l and 21.33±3.51 mg/l, and313.30±6.57 mg/l and 270.33±26.16 mg/l respectively which exceeded the standards of the WHO and FMEnv. The high values of analyzed parameters were an indication of the groundwater contamination. Heavy metals in the Rumuosi dumpsite indicated 11.31±1.33 mg/l, 11.01±0.67 mg/l, 361.84±12.31 mg/l, 118.03±5.74 mg/l and 84.77±4.84 mg/l for Pb, As, Mn, Fe and Zn respectively. While Heavy metals thresholds at Igwuruta were 0.004±0.005 mg/l, 0.04±0.07 mg/l, 0.05±0.08 mg/l, 0.08±0.14 mg/l and 0.15±0.04 mg/l respectively. Rumuosi thresholds exceeded the standards, indicating that the exposed local people in the nearby communities may experience cases of non-carcinogenic and carcinogenic health risk by drinking the groundwater. The leachate pollution index (LPI) at the studied dumpsites indicated 13.58 and 12.9 which exceeded the internationally accepted benchmark of 7.38; indicating that the Rumuosi leachate was more polluted than Igwuruta leachate. The analysis of variance (ANOVA) of the pollutant characteristics indicated a significant difference at p=0.05 across the physicochemical and biological indicators at Rumuosi dumpsite over Igwuruta dumpsite. The researcher recommended the practice of sanitary landfill which may reduce the risk of leachate percolation, a primary source of groundwater contamination.

This study evaluated the bacteriological quality of groundwater from Imiringi in Ogbia Local government area of Bayelsa State, Nigeria. Groundwater samples were obtained in triplicates from four locations in the study area and analyzed for the bacteria quality using standard protocols. Results showed that the microbial density ranged from 2.97 – 6.03 x 104 cfu/ml (for total heterotrophic bacteria counts), 4.17 – 5.43 x 102 cfu/ml (for Enterobacteriaceae bacteria counts) and 0.00 – 1.48 x 102 cfu/ml (for Salmonella-Shigella counts). Statistically, there was no significant difference (p>0.05) across the various locations for each of the parameters. The density observed were higher than the allowable limit of 1.0 x 102 cfu/ml for drinking water as recommended by World Health Organization/Food and Agricultural Organization, and maximum permissible level of 10cfu/ml for total coliform as specified by Standard Organization of Nigeria. The prevalence of bacteria isolated in the water samples were Aeromonas species (8.00%), Citrobacter species (7.50%), Escherichiacoli (20.75%), Klebsiella species (5.50%), Pseudomonas species (12.00%), Salmonella species (2.25%), Shigella species (3.25%) and Staphylococcus species (40.75%). From the bacteria density and diversity, the water is not potable. Some of the bacterial found are of public health importance. Hence, there is a need to adequately treat the water using chlorination and boiling techniques before drinking.

The Impact

Most of the drinking water supplies of Atakpamé town is assured by wells and boreholes. The quality of this water is threatened by human activities. This study is to evaluate the impact of agricultural techniques and wastewater management on the evolution of the physicochemical quality of well and borehole water, for an understanding of the acquisition of groundwater mineralization in this commune. The water was collected and analyzed and, the results submitted to statistical processing using the software XLSTAT 2018.6 shows that the most downgrading physicochemical parameters are pH, conductivity and nitrates, compared to World Health Organization (WHO) standards. Factor analysis and correlation between the parameters explain the source of nitrate pollution which is linked to the farming and other human activities. The hydro chemical facies represented in the Piper diagram using the diagram software are in majority chlorinated, sodipotassic. Qgis software led to the spatial representation of the nitrate pollution. This pollution is high in Abotèssè, Aféyé-Kpota, Idiotsè and Ikotadi localities. The Hierarchical Ascendant Classification (HAC) of sampled water point gives four important homogeneous subgroups for future sampling selecting a point while representing the subgroup under surveillance.
