“…Other properties include soil pH, total porosity, bulk density, and hydraulic conductivity. The mean pH value of the soil samples for onsite is 6.4 (greater than that of the control) near the values of the work of Ewemoje et al [19] with pH values ranging between 6.5 and 7.5. The mean pH value recorded for offsite in this work is 5.9.…”

In recent times, large waste is produced especially in an urban area due to population with careless handling which calls for worries. Hence, the study determines the effect of Akanran dumpsite on the groundwater quality for drinking and domestic purposes. It employs the geophysical and geochemical methods. Wenner configuration was adopted with constant electrode separation ranging from 5 to 25 m to acquire five profiles within and outside the dumpsite and processed using DIPROWIN 4.01 software. Soil and water samples were collected and analysed. The 2-D pseudosection revealed a very low resistivity value which is less than 10 ohm-meter and is suspected to be leachate infiltration which migrates to a depth of 7 m. The results of soil analysis show that clay ranges between 9.61 - 18.8 %., silt between 9.27 – 19.7 % and an average bulk density of 1.48 (relatively high for a sandy loam) which suggests that infiltration of the leachate is minimal. The pH of the water sample analysis obtained is 6.9, suggesting acidic concentrates in the groundwater of the study area. However, this pH value for drinking water is within the permissible level of 6.5 – 8.5 indicating that the groundwater in the study area is suitable for drinking and also for other purposes. A Nitrate level of 2.56 mg/l in the water sample falls within 50.0 mg/l, and nitrite level of 0.09 mg/l which is moderate when compared to the permissible level limit of 0.20 mg/l. The concentration of heavy metals in hand-dug well sample from Akanran dumpsite are Zn (1.81 mg/l), Cu (0.38 mg/l), Cr (0.003 mg/l) which are within the permissible level limit and Pb (0.21 mg/l) which recorded high metal concentration which may suggest that the dumpsite contain waste metals which may leach down the soil. In conclusion, the groundwater in the area of the survey is safe and there is possible contamination with time.

“…Ajakanga waste dumpsite and its environs are underlain by biotite-hornblende gneiss, migmatite gniess and quartzite (Ogunseiju et al, 2015). Previous studies conducted in this area revealed elevation increased in heavy metals concentration due to the dumpsite (Oguiseju et al, 2015;Ganiyu et al, 2016, Ewemoje et al, 2017Akintola and Bodede, 2019a).Composite samples were collected at 0-0.20cm from different sampling points from the dumpsite and also from 500m (upslope) away from the dumpsite, this serve as control.…”

“…Higher levels of heavy metal concentrations in soils from dumpsites and their ecological effects has been reported by several researchers (Akintola and Bodede, 2019b;Famuyiwa et al, 2018, Hu et al, 2018Akintola et al, 2020). Ajakanga dumpsite and its environ has been reported to have elevated concentrations of heavy metals due to anthropogenic influence of the wastes (Oguiseju et al, 2015;Ganiyu et al, 2016, Ewemoje et al, 2017Akintola and Bodede 2019a). Akintola and Bodede (2019a) in their study indicated no to low heavy metal pollution level in the vicinity of Ajakange dumpsite and no probable health risk was observed as the total hazard index of all the heavy metals was less than one.…”

Heavy metal contamination has become a serious ecological problem due to its toxic effects on soils, plants and human. Experimental study was conducted on dumpsite soil to assess the potential of Ricinus communis to accumulate heavy metals from the soil using bioconcentration (BCF) and tanslocation factors (TF). Heavy metals concentration (mg/kg) in dumpsite and control soil before planting were Mn (50.68- 220.08); Zn(29.01- 135.56); Cu (8.92- 86.88), Pb (5.88-48.86), Ni (3.01-7.99) and Co (1.78-6.88) while the concentration in soils after planting were Mn(29.89- 135.21); Zn (15.11-88.21); Cu (3.89-50.22), pb (3.68-31.56), Ni (1.22-3.56) and Co (0.67-2.68) in Mg/kg. Ricinus communis showed BCF greater than 1 for Ni and Co and less than 1 for Mn, Cu, Zn and Pb while TF is greater than 1 for all the determined heavy metals. The dumpsite soils have higher heavy metal concentration than the control soil. The levels of heavy metals concentration in soils and plants are in the order of Mn> Zn> Cu> Pb> Ni. Significant reduction (P<0.05) was observed in the heavy metal concentrations in the soils before and after planting indicating their accumulation in the plants. Results of this study indicate the accumulation of heavy metals in Ricinus communis plants and its potential for effective removal of Cu, Zn, Pb, Ni, Co and Mn from the dumpsite soils.

“…There are clear indicators that groundwater is under threat due to the inadequate landfilling systems/practices and this has been previously highlighted (Agamuthu, 2012;Ewemoje et al, 2017;Majolagbe et al, 2016;Salami et al, 2015;Ukpebor et al, 2003;Zumar M. A. Bundho, 2018). Salami et al (2015) reported values above World Health Organization (WHO)/National Environmental Standards and Regulations Enforcement Agency (NESREA) (Nigeria) specific limits for some contaminants in groundwater resources.…”

Municipal solid waste (MSW) management remains a challenge in developing countries due to increasing waste generation, high costs associated with waste management and the structure of the containment systems implemented. This study analyses the classification of landfilling systems by using documented cases reported mainly in publications in waste management in relation to nonengineered landfilling systems/approved dumpsites in Sub Saharan African (SSA) countries from 2000 to 2018. The work identifies an existing system for the classification of landfill sites and utilises this system to determine the situation of landfill sites in SSA countries. Each article was categorised according to the main landfilling management practice reported: Uncontrolled dumping, semi controlled facility, medium controlled facility, medium/high-engineered facility or high state-of theart facility. Findings suggested that 80% of the documented cases of landfill sites assessed in SSA countries were classified as level 0 or 1. The structure of the containment and controlled regime were identified by the focus group discussion participants as important predictors of possible strengths, weaknesses, opportunities and threats for the landfill sites considered. The study represents the first identifiable and comprehensive academic evaluation of landfill site classification based on site operations reported in the available peer reviewed literature. The information provides insight on the status of landfill sites in SSA countries with respect to the landfilling management practice and a baseline for alternative corrective measures.
