“…Reductive dissolution of oxide and hydroxide of minerals containing Fe and Mn is the initial step for the release of arsenic from the sediment into the groundwater. Fe oxides are considered the most likely sources of As by other studies (Smedley 1996;Smedley et al 2007;Kortatsi et al 2008a;Bhattacharya et al 2012). Smedley et al (2007) noticed that arsenic-bearing sulphide minerals are also sources of arsenic release in groundwater in zones of mineralized Birimian volcano-sedimentary rocks.…”

The review of studies on arsenic in African waters shows that arsenic can be found in high concentrations in both surface water and groundwater. Arsenic concentrations in African groundwater range between 0.02 and 1760 μg L −1 , whilst the level of arsenic in surface water is ranged up to 10,000 μg L −1 . This high level of arsenic in surface water is related to mining operations, agricultural drains, local sediments, disposal, and incineration of municipal and industrial wastes. However, mining activities remain the main source of surface water pollution. They have thereby a strong impact on the concentration of arsenic in the environment. As for groundwater, high levels of arsenic occur in natural conditions. It is due to the presence of iron oxides; sulphide minerals such as pyrite, arsenopyrite, and chalcopyrite; volcanic rocks; and geothermal waters. Few studies in Africa make the link between human health problems and high levels of arsenic in water. Only two articles were found dealing with arsenic remediation. This shows that arsenic, which constitutes a major public health issue in the world, has less interest in Africa although high concentrations of arsenic have been found in both surface water and groundwater in some African countries. Most of the studies carried out on arsenic issues in Africa are dedicated to the characterization and the quantification of the pollution, but studies on the risk to human health and treatment systems are limited. The arsenic issue in Africa needs special attention in order to avoid the problems experienced in some areas mainly in Asia.

The study assessed the impact of an operating Tailings Storage Facility (TSF) of Adamus Resources Limited (Nzema Gold Mine) in the Ellembele District of the Western of Ghana on catchment surface and groundwater quality. Water samples were collected between June and December 2014 from seventeen (17) sampling sites including the TSF decant water (TSF-DW), three (3) streams, a water storage dam, a pond and eleven (11) groundwater monitoring boreholes within 500 m radius of the mine's Tailings Storage Facility. Samples were analyzed for pH, true colour, electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), biological oxygen demand (BOD), dissolved metals (arsenic, cadmium, copper, mercury) and cyanide (weak acid dissociable cyanide (WAD), free cyanide and total cyanide) using standard procedures. The TSF-DW reported elevated arsenic, free cyanide and TSS concentrations above GHEPA guideline for effluent discharge. Elevated TSS and arsenic concentrations above GHEPA limits were reported in PWSD which is a pond uphill of the TSF and a receptor to effluents from illegal mining sites on the mine's concession. All other parameters recorded in surface and groundwater bodies studied were within WHO guideline limit for potable water. Results of the study suggest that the quality of surface and groundwater around the TSF has not been adversely affected even though the TSF is contaminated. Study findings suggest that well-engineered tailings dam ofARLwith its effective liner and management systems may have provided a safe structure and prevented contamination of water resources within its catchment.

Soils may be contaminated by gradual accumulation of high metals waste and metalloids, spillage of leaded petrochemicals, run off from agriculture lands, sewage sludge, wastewater, animal manure, combustion residues and paints through the activities of expanding industrial areas (Aloysius et al., 2013, Adelenka et al., 2011). One of the major sources of increasing heavy metal concentration of the environment, in most developing countries is the activities of auto mechanics (Adewole and Uchegbu, 2010 as cited in Aloysius et al, 2013). In Ghana, auto mechanic workshops are found in any available piece of land that is not developed in the vicinity of urban towns and cities where people reside. These auto Technicians are involved in the repair and maintenance of automobile, auto-electrical, welding and soldering, vehicle body spraying and other general services (Adams Sadick et al, 2015, Adelenka et al., 2011, Ipeaiyeda and Dawodu, 2008). In most of Nigeria states, a large track of land is allocated to a group of small scale auto mechanic technician and designated as "mechanic village" where most of the technicians come together along with the auto spare parts dealers to practice their trades (Adelenka et al., 2011, Nwachukwu et al., 2011,
