“…Diffuse pollution includes agricultural practices, atmospheric fallout, and other sources. Changes in land usage, such as the clearing of vegetation, over-abstraction of groundwater, or excavation below the water table, can also contribute significantly to groundwater pollution (Tredoux et al 2004). Groundwater pollution not only affects water quality, but also threatens human health, economic development, and social prosperity (Milovanovic 2007).…”

Physico-chemical characteristics of 74 boreholes from communities within Densu Basin were assessed following procedures outlined in Standard Methods for the Examination of Water and Wastewater. The aim was to assess the status of the boreholes water quality for any contamination for management action to ensure the quality of health of the people in the area. The water quality parameters analyzed included conductivity, pH, turbidity, color, major ions, nutrients, and metals. The study showed that most of the physico-chemical constituents were within the WHO guideline limits. pH values ranged from 6.0 to 8.21, while conductivity varied between 117 and 3,500 lS/cm and turbidity from 0.6 to 19.0 NTU. However, a few of the parameters fell outside the limits prescribed by the World Health Organization (WHO 2004). Fourteen, 9, and 7% of the boreholes exceeded the WHO guideline values for nitrate (NO 3 ), fluoride (F -) and iron (Fe), respectively. Locations where high concentration of Fe and Mn occurred, efforts must be made to remove them to discourage the use of surface waters which may be contaminated by harmful bacteria.

“…Located largely in a semi-arid part of the world, the country's water resources are, in global terms, scarce and extremely limited [1] and a key environmental problem facing the country is water pollution. This pollution arises from many sources, including industrial, mining, and municipal effluents, and runoff of biocides, nutrients, and pathogens from agricultural lands, urban areas, and informal settlements with their characteristic poor sanitation [2,3]. Biological and chemical contaminants [4 -6] represent a health risk if suitable health protection measures are not taken.…”

Failures of sewage treatment systems, both within and outside South Africa, are most commonly ascribed to inadequate facilities and other factors resulting in the production of poor quality effluents with attendant negative consequences on the receiving watershed. The impact of the final effluent of a wastewater treatment facility in a suburban community of the Eastern Cape Province of South Africa on the physicochemical qualities of the receiving watershed was assessed between August 2007 and July 2008. Water quality parameters were analyzed according to the South African Department of Water Affairs and Forestry standards. The effluent quality was acceptable with respect to the pH (6.9–7.8), temperature (13.8–22.0°C), dissolved oxygen (DO) (4.9–7.8 mg/L), salinity (0.12–0.17 psu), total dissolved solids (TDS) (119–162 mg/L) and nitrite concentration (0.1–0.4 mg/L). The other physicochemical parameters that did not comply with regulated standards include the following: phosphate (0.1–4.0 mg/L), chemical oxygen demand (COD) (5–211 mg/L), electrical conductivity (EC) (237–325 μS/cm), and turbidity (7.7–62.7 NTU). The results suggest that eutrophication is intensified in the vicinity of the effluent discharge points, where phosphate and nitrate were found in high concentrations. The discharged final effluents had detrimental effects on the receiving body of water, thus suggesting the need for regular and consistent intervention by appropriate monitoring and compliance agencies to ensure adherence to acceptable standards for discharged effluents.

“…The common parameters influenced by decomposing activities in cemeteries include pH, EC, Cl, NO 3 , SO 4 , P, Na, K, Ca and Fe (Üçisik & Rushbrook 1998;Young et al, 2002;Sawyer et al, 2003;Tredoux et al, 2004;Idehen & Ezenwa, 2018). With the exception of pH, SO 4 and Fe the other parameters including Cl, NO 3 , Na, and K were generally higher in the groundwater samples obtained from the cemetery peripheral when compared to the Reference Site.…”

This paper investigated the comparative analysis of groundwater contamination in Third Cemetery and Costain Dumpsite in Benin Metropolis, South South of Nigeria, using Electrical Resistivity Tomography (ERT) and Physicochemical analysis of water. The implications of land utilization for burial of dead human bodies in the form of cemeteries, many cases associated with coffin and caskets used for interment of remains and the location of refuse dump have received no consideration in Nigeria. Interment of bodies in cemeteries and dumping of refuse in dumpsites remain widespread practice and the only alternative endpoint to dead bodies and disposal of wastes in Nigeria. In Nigeria, this practice had not been perceived as having a significant potential contaminant effect in the environment and especially the groundwater component as search of literature attracted no such study to the country. In Benin City and Nigeria in general, the major cemeteries and dumpsites are located close to human residential areas and virtually all the populace within this locality depends on groundwater as the primary water source for various domestic purposes. Res2Dinv was employed in both sites as the geophysical method. The investigation of cemeteries is always difficult and challenging task in geoforensic prospective. Most researchers assess the impact of interment on the environment by comparing study results from cemeteries with data from reference sites. This study is based on this premise. The 2-D Geological Models showed that both Third Cemetery and Costain Dumpsite contained leachate plumes of various degrees as indicated by the low resistivity values, which infiltrated into the groundwater.
