“…Frisbie et al, (2009) have demonstrated excessive levels of lead (17 μg.L -1 ) and other heavy metals in the water from some boreholes wells in Bangladesh. Arain et al, (2014) and Rasool et al, (2016) also have found cadmium concentrations (12.7 and 67.68 μg.L -1 , respectively) higher than the permissible limits.…”

Groundwater is one of the important sources of drinking water In Jijel (northeastern Algeria). Various analyses have shown critical concentrations of lead and cadmium in several groundwater sources used for drinking. The aim of this study is to evaluate the contamination by lead and cadmium of boreholes and hand-dug wells located in the catchment of the Nile River. Therefore, chemical analysis was performed on drinking water samples from eight boreholes; tow hand dug wells and one spring supplying Jijel city in drinking water. The water samples were examined for the presence of cadmium and lead using the SAA- 6200 Atomic Absorption Spectrophotometer (Shimadzu Corporation). The results of this study show high concentrations of lead (ranged from 72.84±0.26 to 458.95±0.55 μg.L-1) and cadmium (ranged from 12.41±0.88 to 33±0.38 μg.L-1) in all water samples. These concentrations far exceeded permissible values according to the WHO are drinking water posing a potential health risk for the public. The water quality in the studied area of Nile River basin must be considered very low.

“…The upper, middle and bottom positions of the surface water sources served as up-mid and downstream, thus representing the replicates for each source. The temperature of the water samples was taken immediately at the sites of collection using a simple thermometer calibrated in degree Celsius (Rasool et al 2016). Insoluble matter was removed from the samples by filtration using the Whatman filter papers number 42 (Kramer 1994;Eaton et al 1995).…”

Open cast mining: threat to water quality in rural community of Enyigba in south-eastern Nigeria

2018

View full text Add to dashboard Cite

Enyigba in southeastern Nigeria is one of the agrarian communities facing water scarcity challenges. The open cast mining activities in the region are also compounding the water problems as a result of leakage of heavy metals that pollute the limited water resources. This study is conducted to document the current state of surface water contamination by heavy metals and its impact on domestic and agricultural uses. Thirty water samples were collected from five sources at both the upstream, middle stream and downstream of each of the selected sites. The heavy metals were analysed using the standard laboratory methods. Generally, the average concentrations of As, Cd, Cu, Pb and Zn in the studied water bodies were 17.68, 4.30, 3.14, 0.05 and 35.57 mg/l, respectively, which were above the WHO permissible limit. Contamination of water above WHO permissible limits with heavy metals in the surface waters, because of open cast mining, is considered a serious threat to both domestic and agricultural usage. The need for establishment of treatment facility, periodic monitoring of heavy metal levels, recycling plants and principal technologies to monitor the mine sites are hereby recommended.

“…The cluster analysis procedure was used as classification technique designed to group observations (sampling points) or variables (physico-chemical parameters of water) into clusters based upon similarities (Rokach, 2010). The results of cluster analysis are useful in interpreting large sets of data indicating patterns of similar objects (Horovitz et al, 2000;Rasool et al, 2016). Both Ward's method and the Nearest Neighbor's method were used.…”

This article assesses the surface water quality of the Strîmtori-Firiza reservoir by analyzing 14 physicochemical parameters among 9 metals in 18 sampling points. A series of possible reservoir pollutants were identified, depending on the nature of the pollutants and their loading. The novelty of the paper consists in the broad spectrum of investigations that includes spatial distribution cluster analysis and mathematical modeling. This article presents an innovative method of assessing the distributions of the metal loads as maps of metal distribution that are in accordance with the developed mathematical models that aim to present the pollutant distribution and the degree of correlation between the physicochemical indicators. The clusters were generated using Ward's and Nearest Neighbor methods that are less used in the studies concerning the analysis of water quality. Measures for maintaining the quality of the water reservoir are proposed considering the importance of the reservoir as source for drinking/industrial water.
