“…Minimum, maximum, median are non-parametric statistics, which may be used to summarise non-normally distributed water quality data (Caritat et al 1998;UNESCO/WHO/ UNEP 1996). The groundwater pH is typically low, in the range 3.89-6.78 with mean and median values of 5.70 and 5.72, respectively.…”

Hydrochemical and stable isotope ( 18 O and 2 H) analyses of groundwater samples were used to establish the hydrochemistry of groundwater in the Ankobra Basin. The groundwater was generally mildly acidic, low in conductivity and undersaturated with respect to carbonate phases. Major ions except bicarbonate were low and dissolved silica was moderately high. Silicate minerals weathering is probably the main process through which major ions enter the groundwater. Groundwater samples clustered tightly along the Global Meteoric Water Line suggesting integrative, smooth and rapid recharge from meteoric origin. The majority of the boreholes and a few hand dug wells cluster towards the Ca-Mg-HCO 3 dominant section of the phase diagram, in conformity with the active recharge and short residence time shown by the isotope data. Aluminium, arsenic, manganese, iron and mercury were the only trace metals analysed with concentrations significantly above their respective detection limits. Approximately 20%, 5%, 40% and 25% respectively of boreholes had aluminium, arsenic, iron and manganese concentrations exceeding the respective WHO maximum acceptable limits for drinking water. The relatively large percentage of boreholes with high concentration of aluminium reflects the acidic nature of the groundwater.

“…Recovering ecosystems like the one presented in this study are not unique. Mining has been affecting landscapes across the globe (Caritat et al, 1998;Derome & Lindroos, 1998;Eranen & Kozlov, 2006;Bi et al, 2007). On the other hand, our analyses indicate that not just metals are important if recovery by both human and natural causes increases the diversity of fish communities and also increases habitat complexity, we may yet soon see the return of large bodied benthos.…”

Biomass of benthic invertebrates unaffected by industrial damage to lakes despite effects on species composition

Historic metal mining and smelting in the area of Sudbury, Ontario, has resulted in lakes with elevated levels of metals in the sediment, low inputs of terrestrial organic material, and unusual fish communities which led to severe changes in the benthic invertebrate community. Using broad-scale surveys of lakes from Sudbury and an undisturbed reference area, we used multivariate methods to tease apart potential influences of predation by fish, habitat availability, and toxicity of the environment on the biomass of benthic invertebrates. In contrast to many other studies, our response variable is benthic invertebrate biomass-a more relevant factor in food web processes than the numeric densities that are more typically studied. Despite differences in species composition, we observed very similar total benthic invertebrate biomass in Sudbury lakes and reference lakes. Redundancy analysis revealed that different factors shaped invertebrate biomass in the two study areas. Sudbury benthos was strongly influenced by the fish community and metal toxicity with only slight effects of habitat quality. Overall, the fact that benthic invertebrate biomass was similar to reference systems suggests that Sudbury communities may be able to function normally despite the strong direct and indirect effects of multiple stressors.

“…Both SO 4 and Cl show strong correlation with TDs or electrical conductivity (Fig. 5), which indicates that these conservative constituents of groundwater are being steadily enriched up to overall mineralization (Caritat et al 1998). These facts again suggest very little solute loss through drainage, and that lateral movement of groundwater is minimal.…”

Hydrochemical analyses of groundwater samples were used to establish the hydrochemistry of groundwater in the Densu River Basin. The groundwater was weakly acidic, moderately mineralized, fresh to brackish with conductivity ranging from of 96.6 microS cm(-1) in the North to 10,070 microS cm( - 1) in the South. Densu River basin have special economic significance, representing the countries greatest hydrostructure with freshwater. Chemical constituents are generally low in the North and high in the South. The order of relative abundance of major cations in the groundwater is Na+>Ca2+>Mg2+>K+ while that of anions is Cl->HCO3->SO4(2-)>NO3-. Four main chemical water types were delineated in the Basin. These include Ca-Mg-HCO3, Mg-Ca-Cl, Na-Cl, and mixed waters in which neither a particular cation nor anion dominates. Silicate weathering and ion exchange are probably the main processes through which major ions enter the groundwater system. Anthropogenic activities were found to have greatly impacted negatively on the quality of the groundwater.
