“…For example, the authors of [8]. in delineating sulfide deposits, used a combination of geoelectric and ground magnetics methods; [9] combined geoelectric method and direct soil analysis to assess the incessant road failure; and [10] combined the geoelectric method and hydrochemical analysis method to assess the impact of dumpsite to the nearby groundwater system. Even, in the cases of assessment of an object, that is completely physical, some investigators still often use the geoelectric method by combining it with another method [7].…”

An investigation has been conducted, to assess the characteristics of two agricultural lands which exhibit different fertility, in Malang, Indonesia, due to volcanic ash from Mt. Semeru. The assessment was conducted using bore-hole sampling, and the geoelectric method. The results from the XRF analysis of bore-hole data indicate that the two lands have common dominant chemical contents, which are iron (Fe), and silicon (Si), whose concentrations range between 35% to 40% by mass. They also indicate, that at shallow depth, the land of Loc2 has a significantly higher concentration of phosphor (P) than that of Loc1, which is 2.1% compared to 1.2%, and that the concentration of Ca is higher at Loc1 than at Loc2, that is, about 13% to 10%. Other elements of much lower concentrations were also detected at both locations, such as Ti, K, and V. Geoelectric results show that the content of volcanic ash at shallow depths at Loc1 is thicker than that of Loc2. Higher phosphorus concentration obtained at Loc2 may be the cause of its better fertility. The results from the two methods show fairly good correlations, where, for instance, points with high Si concentration are well correlated with high resistivity values, while points whose contents are high in metallic elements have lower resistivity values. The geoelectric method has indicated that fertile land has lower resistivity, compared to less fertile ones. While the geoelectric method may offer less-quantitative results, however, it may play as an efficient complementary method.

“…The road has started to fall short of its structural capacity and hence it is greatly overstrained. In Nigeria, the funds allocated for road development programs have been decreasing constantly over the years as a percentage of the gross domestic product (GDP) [8,16]. Almost all of the allocated funds are utilized for a new construction with little or no funds for maintaining the existing pavements such as Jimeta Bypass thus making it less functional to road users.…”

Many roads in some urban areas in developing countries, such as Nigeria, are characterized by a high level of traffic and, because of limited resources, receive inadequate forms of protection and inappropriate maintenance strategies. Some of the roads have become part of a landfill dump embankment, which cause defects that contribute to road accidents. The study sought to investigate the effect of land use and traffic on road safety along the Jimeta Bypass Road. Vehicle enumeration was carried out by manual counting. Road traffic accident data for the analysis was obtained from the Federal Road Safety Commission in Yola. Physical inspection of the pavement section revealed that it was in an unsuitable condition for riding and safety. The findings also revealed that the road pavement had an annual average daily traffic volume of about 1470 vehicles per day, with tricycles having the highest traffic volume and luxurious buses having the lowest traffic volume. Analysis of variance showed that there was no significant variation in traffic volume between periods (morning, afternoon, and evening); traffic only differs between vehicle types. Accident data collected was found to highly correlate with traffic volume, an indicator that the high traffic volume along the Jimeta Bypass Road could be responsible for the occurrence of road traffic crashes along the road. The study findings also indicate there is need to adopt the maintenance culture by Road Authorities and relevant stakeholders so as to address the failure condition at the onset.

“…Refuse contents consist of various kinds of materials like metallic, organic and non-biodegradable materials (Sunmonu et al, 2012). The intensity of the human's activities has led to increasing volume of solid waste worldwide despite the level of global technological advancement and industrialization (Ganiyu et al, 2015;Abdullahi et al, 2011;Akankpo and Igboekwe, 2011;Murana et al, 2019a). Poor management of solid waste has resulted to a lot of disastrous effects such as aesthetics, environmental hazard and pollution.…”

Pollution of groundwater occurs due to percolation of fluvial water and infiltration of contaminants from water percolating through a solid waste disposal sites (leachate) (Ganiyu et al, 2015).…”

Groundwater contamination has been a worldwide phenomenon. In this research, geoelectric and geochemical surveys were carried out on three active dumpsites in Gusau metropolis for detection of groundwater contamination. Vertical electrical Soundings (VES) were conducted on the dumpsites using Schlumberger array with maximum current electrode separations of 180 m. Five VES were conducted on each dumpsite making a total of fifteen VES along three profiles. Thirty five (35) points were assessed from three wastes dumpsites using portable XRF equipment for the in-situ testing while fifteen (15) representative groundwater samples collected were taken to the laboratory for hydro-geochemical analysis. The field data obtained from VES was analyzed using WinGlink software. The VES results revealed three subsurface layers. The topsoil has resistivity ranging from 1.5Ωm to 48.2 Ωm while the thicknesses vary from 0.47 m to 3.37 m across the profiles. The second layer’s resistivity varies from 5.4 Ωm to 144.35 Ωm and their thicknesses’ ranges from 1.36 m to 16.93 m. The third geoelectric layer has resistivity from 70.0 Ωm to 6003.0 Ωm. The geoelectric results revealed that the top soils in all the dumpsites were characterized by very low resistivity depicting possible pollution and contamination. Environmental pollution models applied to the geochemical dataset revealed Zn, Pb and Cu as moderately contaminants which generally indicated severe potential contamination in the investigated area. While other analytic parameters such as Mn, Cr, Ni and Fe showed low contamination factors. Hydro chemical analysis showed that pH values recorded from the water samples ranged between 7.26 to 8.12 with mean value of 7.50, whereas, recorded Total dissolve solid (TDS) ranged between 377 to 1393mg/L with average concentration of 751.27mg/L. Findings from the study indicated that there may be possible contamination of shallow groundwater system in the nearest future if proper mitigation measures are not taken into consideration at the dumpsites.
