Hydrogeochemical Analysis and Spatial Distribution of Groundwater Quality in Roundhill Landfill Vicinity of South Africa

Abstract

Groundwater is the most reliable resource for consumptive uses worldwide, but it is vulnerable to anthropogenic pollution in this post-industrialization era. Pollution of the resource may result from anthropogenic activities; hence, analysing the effects of leachate on groundwater is imperative. This study assessed the spatial distribution of physicochemical parameters of groundwater in Roundhill landfill vicinity of South Africa and conducted their hydrogeochemical analysis. Water samples were collected from 3 boreholes in the landfill surroundings and analysed for selected physicochemical characteristics. Spatial distribution of these parameters showed dominant pollution by Mn2+, Fe2+, and [Formula: see text], which surpassed prescribed allowable limits of the country in most of the study area. Possibilities of simple dissolution and ion mixing were deduced from the Durov diagram. Magnesium carbonate, sodium chloride, and mixed faces of groundwater were dominant in boreholes 1 to 3, respectively. The dominance of Ca2+, Cl−, Mg2+, and [Formula: see text] ions in some boreholes suggested anthropogenic pollution. Landfill leachate was associated with groundwater pollution in the study area.

“…These developments encourage the generation of solid waste, its indiscriminate disposal, and mismanagement in landfills and open dumpsites. Landfilling is a common solid waste management approach worldwide although such facilities pose a preexisting pollution threat to surface water and groundwater through leachate infiltration in closed and uncovered landfills [4]. Landfill is a place for various kinds of waste so that leachate contains various types of pollutants that have the potential to disturb the environment and human health.…”

A scientometric study on quantitative microbial risk assessment in water quality analysis across 6 years (2016–2021)

“…In developing countries of low and middle income, which have limited preparedness and high vulnerability to climate change, the water scarcity situation is dire. The trend is attributable to high water demand due to population growth, poor infrastructure to harvest water the resource and manage its demand, as well as the resultant wastewater (Fuhrimann et al 2016;Nyika & Onyari 2019;Oki & Quiocho 2020). The pressure is even more in urban and suburban areas with no wastewater management systems and therefore, the population resort to release raw effluent to freshwater bodies resulting in a bigger pollution problem on such resources (Mbanga et al 2020).…”

“…4,5 Continued urbanization is also rapidly causing increasingly poorer quality groundwater. 1,2 However, the resource is strategically most reliable to exterminate the emergent demand. 2 Improved hydrochemical characterization of aquifers in such highly heterogeneous areas, decoupling the relation between groundwater quality and aquifer lithology, could enhance their effective management.…”

“…Its quality characteristics in sub-Saharan Africa exhibit a wide spatial and temporal variability. 1,2 The high volcanic fluoride (>1.5 mg/L) according to World Health Organization 3 depicts widespread variability in groundwater aquifers of the African Rift. 4,5 Continued urbanization is also rapidly causing increasingly poorer quality groundwater.…”

“…Despite the significance of groundwater, 2 the reported high fluoride variability, 4,5 and emergent urbanization 1,2 in the region, knowledge on groundwater evolution and quality remain elusive. In this study, we postulate an evolutionary trend of a fractured volcanic aquifer based on multivariate statistics of groundwater quality data of the area.…”
