Aims: Ideal water for swimming should meet the portable water standard by being transparent, odorless, and tasteless. However, these qualities can be affected by the presence of infectious agents which directly or indirectly contaminate pool water. This study aims at monitoring the microorganisms (bacteria, fungi and protozoa parasites) and pH associated with swimming pool water. Study Design: A random sampling technique was adopted to select the five (5) swimming pools for the study based on accessibility and visitation. Place and Duration of Study: The study was carried out in Port Harcourt Metropolis, Port Harcourt Local Government Area, Rivers State between March 2016 to August 2017. Methodology: Five (5) outdoor swimming pools attached to hotels in Port Harcourt Metropolis, Port Harcourt Local Government Area of Rivers State, Nigeria were randomly selected for the study. Water samples were aseptically collected in duplicates and analyzed for total heterotrophic bacterial count, total heterotrophic fungal count, protozoa and pH using appropriate techniques. Results: The results show that swimming pools with sodium thiosulphate pentahydrate had a mean THBC range from 4x101 cfu/ml - 1.58x103 cfu/ml, mean THFC, 0 cfu/ml - 8x101 cfu/ml and mean pH, 5.9-6.4; for samples without sodium thiosulphate pentahydrate, the mean THBC ranged from 0 cfu/ml - 9.2x101 cfu/ml, mean THF, 0 cfu/ml - 8x101 cfu/ml and mean pH, 5.6-6-2. Protozoa (parasites) were absent in all water samples analyzed. The results further reveals that 95.9% and 100% of the swimming pools samples failed to the meet the <100 cfu/ml and 7.0 – 7.8 World Health Organisation Standards for THBC and pH respectively. The bacteria identified are Bacillus spp., Escherichia coli, Stapylococcus aureus while the fungi identified are Aspergillus spp., Rhizopus spp. and Penicillium spp. Conclusion: The study finds the levels of THBC in the samples with sodium thiosulphate pentahydrate, the presence of Escherichia coli and the pH range a threat to health of bathers. Therefore, the owners should ensure routine decontamination and assessment of water quality.

On preparing of the first management plans of River Basin Districts have been found that diffuse agricultural pol-lution is one of the most important causing factor and the most significant impact on the quality of water bodies. Diffuse agricultural pollution can be from 45% to 80% of nitrate nitrogen pollution load of water bodies. Pollution is transported by water surface and subsurface runoff through sediments from agricultural territories. This article aims at evaluating of relation between the Quaternary sediments and Land use dissemination. The lithological factor (sandy, loamy, argillaceous) of the basin was calculated based on Quaternary map of Lithuania M 1:200000 and Lithuanian river map M 1:50000. The land-use factor of the basin was calculated based on Corine Land cover M 1:100000 using ArcGis software. In order to carry out more thorough analysis of the determination of relation between the Quaternary sediments and Land use dissemination in given territories, sections of 0–50 m, 50–200 m, 200–500 m, 500–800 m, 800–1000 m and >1000 m were established, calculating the distance in meters from the riverbank.

ABSTRACT Surface water and groundwater are continuously used as sources of drinking water in many metropolitan areas of the United States. The quality of water from these sources may be reduced due to increases in contaminants such as Escherichia coli from urban and agricultural runoffs. In this study, a multiplex fluorogenic PCR assay was used to quantify E. coli O157:H7 in soil, manure, cow and calf feces, and dairy wastewater in an artificial wetland. Primers and probes were designed to amplify and quantify the Shiga-like toxin 1 (stx1) and 2 (stx2) genes and the intimin (eae) gene of E. coli O157:H7 in a single reaction. Primer specificity was confirmed with DNA from 33 E. coli O157:H7 and related strains with and without the three genes. A direct correlation was determined between the fluorescence threshold cycle (CT ) and the starting quantity of E. coli O157:H7 DNA. A similar correlation was observed between the CT and number of CFU per milliliter used in the PCR assay. A detection limit of 7.9 × 10−5 pg of E. coli O157:H7 DNA ml−1 equivalent to approximately 6.4 × 103 CFU of E. coli O157:H7 ml−1 based on plate counts was determined. Quantification of E. coli O157:H7 in soil, manure, feces, and wastewater was possible when cell numbers were ≥3.5 × 104 CFU g−1. E. coli O157:H7 levels detected in wetland samples decreased by about 2 logs between wetland influents and effluents. The detection limit of the assay in soil was improved to less than 10 CFU g−1 with a 16-h enrichment. These results indicate that the developed PCR assay is suitable for quantitative determination of E. coli O157:H7 in environmental samples and represents a considerable advancement in pathogen quantification in different ecosystems.

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.

Arsenic, a naturally occurring element seen in the environment and cycled by water has been seen to be a pollutant in soil, water and air. The inorganic form of arsenic is associated with major health problems and cancer mainly arising due to its anthropogenic activities. The content of arsenic was assayed in six rice brands sold in Port Harcourt, Rivers State, Nigeria. The rice samples were ground to powdered forms and subjected to acid digestion before analysis. The Agilent Micro Plasma Atomic Emission Spectrophotometer (MP-AES) was used to analyze the digested samples. Results showed mean arsenic concentration in Vico Rice, the highest as 1.0073. This was followed by Local Rice 0.9420, Marori Benz 0.9140, Golden Stallion Rice 0.861 and the Cap Rice 0.8077 while the least mean concentration of arsenic was recorded in African Princess Rice 0.6417, all in mg/kg. The mean concentration was significantly different in the six brands of rice (P<0.05). The arsenic content in the different rice brand was within the tolerable concentration of 1.4 mg/kg as in cereals and vegetables. This concentration did not exceed the Maximum Permissible Limit of 1 mg/kg hence considered safe for consumption except Vico rice with a higher concentration above 1 mg/kg. This shows that rice brands sold in Port Harcourt pose no health risk for consumers with respect to arsenic content.
