“…Abeokuta is located near a cluster of rocky outcrops on the east bank of River Ogun. It lies between latitude 7.23° N and longitude 3.42° E. The population of Abeokuta is estimated at 451,607 with an annual growth rate of 3.5% (National Population Commission 2010 ; Ogbiye et al 2018 ). The city is joined to Lagos by railway (77 km) or by water (130 km).…”

Groundwater pollution resulting from anthropogenic activities and poor effluent management is on the rise in Nigeria. Hence, groundwater used for domestic purposes is questionable and therefore calls for scientific scrutiny. Investigation of hydrochemical interactions and quality of groundwater resource is essential in order to monitor and identify sources of water pollutants. As a result, groundwater samples were collected from 21 locations in Abeokuta South, Nigeria and analyzed for physicochemical parameters using standard methods. Results obtained were subjected to hydrochemical and geospatial analyses. Water quality parameters investigated exhibited wide variations from location to location. Fe2+, Mg2+, SO42−, Cl−, total hardness (TH), Mn, Na+, NO3−, SiO2, and alkalinity exhibited the highest levels of variation with coefficients of variation of 131.3, 92.8, 83.9, 76.7, 65.9, 64.3, 57.6, 57.2, 57.0, and 52.5, respectively. The average pH value was 6.76 with 71% of the water samples being slightly acidic. Na2+, Mg2+, Fe2+, and EC contents exhibited the most violation of drinking water standards with percent violations of 100, 52.4, 47.6, and 47.6%, respectively. Parameters, such as Mn, Ca2+, NO3−, and CO32−, were within the WHO guideline values for drinking water in all the samples. The highest level of significant correlation was found to exist between Na+ and Cl− (r = 0.84, α = 0.01). Six principal components, which explained 83.5% of the variation in water quality, were extracted with the first (34.1%) and second components (15.7%) representing the influence of mineral dissolution and anthropogenic practices, respectively, on the hydrochemistry of the area. Four hydrochemical clusters were identified with distinctly partitioned water quality. Further analysis revealed that 38, 29, 24, and 9% of the samples were the Na-K-HCO3, Na-K-Cl-SO4, Ca-Mg-HCO3, and Ca-Mg-Cl-SO4 types, respectively. Anthropogenic activities are increasing threat to groundwater quality in the study location and therefore call for urgent attention. There is also a need for routine monitoring of groundwater in Abeokuta.Electronic supplementary materialThe online version of this article (10.1007/s10661-018-6799-8) contains supplementary material, which is available to authorized users.

“…A health risk assessment is a useful tool to estimate the probability of adverse health effects in humans who may be exposed to chemicals in contaminated water, either now or in the future (Yousefi et al, 2018). The method has been applied in different studies of health risk evaluations for fluoride pollution in groundwater (Zhang et al, 2017;Emenike et al, 2018;Samuel et al, 2018;Li et al, 2019;Yousefi et al, 2019). In this study, a health risk assessment was performed to estimate the probability of adverse health effects from fluoride exposure in surface water on human health in the upper reaches of the Yongding River.…”

The excessive exposure to high concentrations of fluoride in drinking water can lead to a serious disease called fluorosis. The upstream region of the Yongding River is an ecological protection area for Beijing. Some studies have reported that there is a high concentration of fluoride in the groundwater in this area. However, there are few data on the distribution of fluoride in surface water and health risk assessments in this area. In this study, the fluoride concentrations were determined by using the spectrophotometric method using data from 2013 to 2017 from 9 surface water quality monitoring stations in the upper reaches of the Yongding River. The health risks of fluoride were assessed using the approach developed by the United States Environmental Protection Agency (US EPA). The results indicated that the fluoride content in the drinking water ranged from 0.30 to 1.50 mg L 1 , with an average of 0.86 mg L 1. In total, 22.7% of the analyzed samples exceeded the Chinese limit of 1.0 mg L 1 for fluoride, and 5.5% of samples had less than the permissible limit of 0.5 mg L-1. Higher fluoride concentrations and fluorosis hotspots were found to be predominately located downstream of the Yanghe River close to the Guanting Reservoir, where 71.4% of samples exceeded the limit of 1.0 mg/L 1. The spatial distribution of high fluoride concentrations was found to be primarily determined by industry. The hazard quotient (HQ) index for children, teenagers and adults indicated that 19.6%, 15.6%, and 5.1% of the samples in the upper reaches of the Yongding River, respectively, posed health hazards to the associated groups. Furthermore, the HQ index more than 1 for children, teenagers and adults had values of 64.3%, 56.1%, and 19.4%, respectively, in samples from the downstream region of the Yanghe River. Therefore, there are potential risks of dental and skeletal fluorosis in the upper river reaches of the Yongding River. It is imperative to take measures to reduce the fluoride pollution in surface water and control fluorosis. Action should be taken to improve the disposal of industrial waste.

The present study aimed to assess the quality of groundwater close to functional brick kilns of the Loralai district of Balochistan using the water quality index (WQI) Model. 15 samples were collected from the bore wells and tube wells situated near brick kilns. To appraise the WQI groundwater samples were subjected to an extensive analysis of physicochemical such as color, odor, taste, pH, Electrical conductivity (EC), Total dissolved solids (TDS), Total hardness (TH), Sulfate (SO4), Chloride (Cl), Fluoride (F), Sodium (Na), Potassium (K), & Arsenic (As). GIS was used to map the sampling location. The descriptive statistical approach and correlation matrix were successfully applied to study the variation and determining the interdependence of various parameters in the Loralai district of Balochistan. Based on the Water Quality Index (WQI) results in the majority of the value of the samples ranged from 48-204 falling in poor water quality category. The assessment proclaims that groundwater sources surrounding brick kilns need a reliable degree of treatment before the consumption of end-users and should be protected from contamination in the future. Contribution/ Originality: This research will serve as a pioneer study of groundwater quality of Loralai District Balochistan. It uses Mathematical models such as WQI, and descriptive Statistical analysis such as correlation Matrix to evaluate the water quality and level of contamination around brick kilns.
