The performance status of access to safe water sources in a community is determined by the percentage of the population using domestic water sources that meet international standards. Nigeria achieved a total of about 67% of the population with access to safe water sources by 2015 at the end of the period of the Millennium Development Goals. Ensuring universal access to safe and affordable drinking water for all requires investment inadequate infrastructure, this requirement led to the investigation of facilities currently available in Bauchi State of Nigeria. A baseline survey was conducted in the State towards monitoring progress on development goals, the baseline survey covered safe water sources and health facilities in State. It was found that Dambam Local Government Area recorded the highest access of 60.6% of the population with access to safe water sources, 33.33% of the population in Bauchi Local Government Area has access to public safe water sources while the lowest access recorded 5.26% in Toro Local Government Area. The functionality status of installed safe water sources in the State is currently low; Bauchi Local Government Area recorded a functionality status of 46% for the public motorized schemes and 66% functionality status for the handpump equipped boreholes. It was recommended that in working towards achieving Sustainable Development Goal number 6, massive repair and rehabilitation exercise is required to be carried out on non-functional water supply sources in the State to improve the access to safe water sources.

Background: Majority of the human population in semi-urban and urban areas in Nigeria are heavily reliant on well and stream water as the main source of water supply for drinking and domestic use due to the inadequate provision of potable pipe borne water. These groundwater sources can easily be fecally contaminated and thus, increase the incidence and outbreaks of preventable waterborne diseases. This study was carried out to determine the bacteriological quality of some well and stream waters sources in Ikwerre, Emohua and Etche Local Government Areas of Rivers State. Methodology: Twenty-four sampling sites with 8 from each Local Government Area were randomly selected for this study. A total of 48 samples, 2 from each of the sites were collected aseptically for 12 months. Samples were analysed using membrane filtration technique for total heterotrophic bacterial count and total coliform count. The well and stream water samples were also cultured for E. coli, Salmonella, and Vibrio sp. Results: The results show that Emohua Local Government Area had the highest total heterotrophic bacterial count of 5.2 x 103 cfu/ml. This was followed by Ikwerre LGA with total bacterial count of 4.3 x 102 cfu/ml, while Etche LGA had 3.1 x 102 cfu/ml. The total coliform count ranged from 25 cfu/100ml to 50 cfu/100ml for the three LGA’s, whereas the faecal coliform count was between 12 cfu/100ml and 20 cfu/100ml. The total coliform, E. coli, Salmonella and Vibrio counts from the three local government areas occurred above the WHO stipulated zero count in 100ml of water. Conclusion: The results from this study showed contamination of all the wells studied with faecal coliforms thus, indicating the presence of other enteric pathogens and a potential source for waterborne disease outbreaks. Well water in Ikwerre, Emohua and Etche Local Government Areas of Rivers State are not safe for drinking without additional treatment like disinfection or boiling. Periodic testing and constant monitoring of these water sources should also be done to meet up with the World Health Organization Standards in the provision of safe, clean drinking water.

Radon concentration in water is one of the major problems of radiation protection in recent years. This work assessed the radon concentration in water sources from Sabon Gari, local government area, Kaduna State. The water samples were collected and analyzed using Liquid scintillation counter (Tri-Carb-LSA1000).  The overall mean radon concentration of the waters samples was found to be 14.9 BqL-1, which is higher than the maximum permissible limit of 11.1 BqL-1 by USEPA and the world average value of 10 BqL-1 by UNSCEAR and WHO. The overall Annual effective dose (AED) due to inhalation of radon is calculated to be 37.6 μSvy-1. This value is less than the permissible limit of 100 μSvy-1 set by WHO. Also, the overall AED due to ingestion is estimated as 109.0, 154.2, and 180.4 μSvy-1 respectively for both Adult, children and Infant, which is slightly higher than the WHO permissible limit of 100 μSvy-1 for adults and less than the permissible limit of 200 μSvy-1 for children. This result shows that the inhabitants of Sabon Gari local government are safe from any radiological health related effects that may result from the inhalation of radon gas. Also, both Children and Infant are safe from any immediate radiological health risk, but for Adults, consuming any of the water sources (Well, Borehole and Surface) over a prolong period of time is not completely safe and may result in radiological health hazard
