Arsenic (As) contamination in the ground waters of North Eastern states of India poses a serious threat to human health. A study has thus been carried out to investigate the extent of Arsenci contamination in parts of states of Mizoram and Assam. The study shows that a contamination is extensive in the low lying areas of Barrack Valley located mainly to the north of Mizo hills region.Arseni contamination in suruma basin is confined to the Hollocene alluvium.

High arsenic (As) concentrations (12-97 μg/l) have been detected in the groundwater of the Barak Valley region (Assam), northeastern India. The main source of As is traced to the litho-facies of the Tipam formation. More »»

Douala metropolitan city loated in the littoral province of Cameroon,has experienced a rapid urbaniation and industralisation. The city depends heavily on groundwater as a resource. Due to ubiquitous sources of pollution, groundwater quality and contamination has become an imprtant issue for this urban groundwater supply. This study uses the major ion chemistry of groundwater together with the minerallogical and chemical composition of sediments to investigate the chemical characteristics and contamination of groundwater. An attempt has been made to identify the different factors controlling the chemical composition of groundwater. Groundwater is acidic (4.1-6.9) and the chemistry is more influenced by atmospheric inputs and anthropogenic activities than by aquifer water reactions. The ionic content of groundwater shows a large variation with electrical conductivity ranging from 34.3-1021µs/cm. However, Cl and HCO3 are dominant anions meanwhile Na and Ca are dominant cations. Groundwater from natural low residential areas has low electrical conductivity and Ca-Na-HCO3 type where as the chemical composition of groundwater is shifted to Ca-Na-Cl ( NO3 +SO4 )downstream with maximum electrical conductivity and high nitrate levels above the guide limits occuring in the highly urbanised, settlements at the Cente of the study area.Groundwater is vulnerable to acid deposition due to the resistant nature and the low level of base forming cations in the aquifer sediments, which provides very little buffer for acid inputs.

Systematic investigations on seasonal variations in arsenic (As) concentrations in groundwater in both space and time are scarce for most parts of West Bengal (India). Hence, this study has been undertaken to investigate the extent of As pollution and its temporal variability in parts of Murshidabad district (West Bengal, India). Water samples from 35 wells were collected during pre-monsoon, monsoon and post-monsoon seasons and analyzed for various elements. Based on the Indian permissible limit for As (50 $μ$g/L) in the drinking water, water samples were classified into contaminated and uncontaminated category. 18 wells were reported as uncontaminated (on average 12 $μ$g/L As) and 12 wells were found contaminated (129 $μ$g/L As) throughout the year, while 5 wells could be classified as either contaminated or uncontaminated depending on when they were sampled. Although the number of wells that alternate between the contaminated and uncontaminated classification is relatively small (14%), distinct seasonal variation in As concentrations occur in all wells. This suggests that investigations conducted within the study area for the purpose of assessing the health risk posed by As in groundwater should not rely on a single round of water samples. In comparison to other areas, As is mainly released to the groundwater due to reductive dissolution of Fe-oxyhydroxides, a process, which is probably enhanced by anthropogenic input of organic carbon. The seasonal variation in As concentrations appear to be caused mainly by dilution effects during monsoon and post-monsoon. The relatively high concentrations of Mn (mean 0.9 mg/L), well above the WHO limit (0.4 mg/L), also cause great concern and necessitate further investigations. More »»
2009 Journal Article G. Eneke Takem, Chandrasekharam, D., Ayonghe, S. N., and Thambidurai, P., “Pollution characteristics of alluvial groundwater from springs and bore wells in semi-urban informal settlements of Douala, Cameroon, Western Africa”, Environmental Earth Sciences, vol. 61, pp. 287–298, 2009.[Abstract]

Alluvial groundwater from springs and bore wells, used as the major source of water for drinking and other domestic purposes in the semi-urban informal settlements of Douala, Cameroon, has been studied. Six representative springs, four bore wells and two hand dug wells, situated in the Phanerozoic basin were selected, from which a total of 72 water samples were analyzed for chemical characteristics and indicators of bacterial contamination. The results showed anthropogenic pollution, evident from high concentrations of organic (up to 94.3 mg NO3/l nitrate) fecal coliform and fecal streptococcus detected in the springs and bore wells (with values of 2,311 and 1,500 cfu/100 ml, respectively). The pH ranged from 3.4–6.5, which is lower than the guidelines for drinking water. Groundwater samples from background upstream inland natural areas W1 and W2 had low electrical conductivity (54.2 and 74.8 $μ$s/cm, respectively) and major ions, which increased downstream in the valleys, peaking in the more densely settled areas. An acceptable concentration of solutes was observed for the bore wells except for a single sample from B4. The bore-well sample B4 registered the highest microbial content (2,130 cfu/100 ml) and nitrate level(26 mg/l), which could be due to the bottom of this well lying just at or close to the zone of mixing between sewage and groundwater. The absence of a direct correlation between nitrate and fecal matter suggests multiple sources of contamination. The shallow alluvial aquifer consists of unconsolidated deposits of gravel, sand, silt and clay. The springs, therefore, receive direct recharge from the ground surface with limited contaminant attenuation, which leads to water quality deterioration, especially during the rainy season. This shows the urgent need to put basic service infrastructures in place. The local population should be sensitized to the importance of chlorinating and boiling drinking water to prevent health hazards. More »»
