Effects of Solid Waste Disposal on the Receiving Soil Quality in Benin Metropolis, Nigeria

The present study investigated the impact of solid waste disposal on the receiving soil quality of four major dump-sites and a control site in Benin Metropolis, Edo State, Nigeria by collecting samples at three distances from the dump-sites of 0 – 50 m, 50 – 100 m, > 100 m at 0 – 30 cm depth. The investigation spanned from July 2011 to December 2011. Results obtained during these months were pooled together to obtain single mean for each sampling station or distance. Results showed that pH values ranged between 5.23 and 5.83, recording slight variations from one site to the other, with no significant differences (P> 0.05) across the study stations and distances. Electrical conductivity concentrations ranged from 562.00 - 982.33μS/cm, with the highest concentrations recorded at 0 - 50m, whereas concentrations were lowest beyond 100 m. Significant increased concentrations of heavy metals (Fe, Mn, Zn, Cu, Cr, Pb, Ni and V) were reported when compared with the control. The bacterial count (F= 7.527,df = 3) and fungal count (F=5.749, df = 3) of soil sample did not show a significant difference (P > 0.05) between the test stations and the control station respectively, although the mean ranks were highest in the control station.

Surface And Groundwater

Abstract The impact of uncontrolled municipal solid waste disposal of 3800 tons per day on surface and groundwater in the downstream of Jawaharnagar dumping site was studied. The un-engineered solid waste dumping yard site spreading over an area of about 300 ha is located on topographic high (hillock), and falls in Madyala stream and Dammaiguda watersheds of Musi sub-basin. The area is underlain by granites of the Archaean age. Both surface and groundwater samples, collected covering hydrological cycles of 2011and 2012, were analyzed for major chemical constituents. During 2012, 15 samples of both seasons were tested for BOD, COD, and TOC. The mean values of some tested chemical constituents of surface water samples (15) were - EC 13066 m S/cm, TH 753, Na+ 813, K+ 530, HCO3− 978, Cl− 1304, and NO3− 262 (all in mg/l) which prove that the tanks and stream near dump yard were pools of leachate. The average values of contaminated groundwater samples among the four sampled sessions (17) indicate EC was above 5000 m S/cm, TH 1624, Cl− 1502, and SO42− 284 (all in mg/l) which were found much above the threshold values. Very few samples were found suitable for drinking purpose and most of the samples fall in Good class of WQI. Very high content of TOC, BOD, and COD in both surface and groundwater samples indicate the presence of organic pollutants sourced from domestic waste dumps. Wide temporal and spatial variability in the concentration of many ion species can be attributed to deviation in rainfall, topography, plume dynamics, and aquifer hydraulics. Low resistivity values (5 to 25 ohm.m) at a distance of 4 km from the dumping site and high infiltration rate (29 cm/hr) at Madyala stream, which were contaminant hotspots, indicate the mass flux was controlled by hydrological features. Scattered and limited distribution of contaminants can be accounted for heterogeneous nature of country rocks, retarded lateral and vertical flow of water which restricts the movement of contaminants to certain preferred pathways. The study supports the hypothesis of solid waste dumps were the epicenter of pollution which generates leachate and dissipate contaminants to the aquatic environment influenced by factors like soils, topography, and aquifer hydraulics and contaminant kinetics.

The Impact

Municipal waste dumpsites contain pollutants which are either water-solution or are capable of being moved along the path of water during percolation through the soil to groundwater. This study was therefore carried out to investigate the impact of solid waste dump-sites in Benin City on the receiving groundwater quality. Four stations were chosen for this study, with each station located within one Local Government Area. These stations were dump-sites at Ikhueniro (station 1), Costain (station 2) and Ugbioyoko (station 3). Omaghe (station 4) was used as the control station without waste dumpsite. Soil samples were collected at three distances from the dump-sites of 0-50m, 50-100m, >100m at 0-30cm depth of top soil and analyzed while the boreholes used were within 120m radius from the dump-sites. This investigation spanned from July 2011 to December 2011. Results showed that water samples were found to be enriched with heavy metals (Fe, Mn, Zn, Cu, Cr, Pb, Ni and V) more than the control water sample; these were however within WHO and FMEnv. regulatory limits for drinking water. The mean pH values of the sampled water fluctuated between 4.50 and 5.57 and were not within the WHO and FMEnv. regulatory limits of 6.5 to 8.5 set for drinking water. ANOVA revealed a highly significant difference (p < 0.01) between the means of the following water parameters; Ca, Na, K, Mg, electric conductivity, Salinity, HCO3, and total soluble solids. The Kruskal-Wallis Test revealed that aerobic bacterial count was significant (p < 0.05) with the highest mean value in station 1 (17.17 x102 cfu/ml) and lowest mean value in station 4 (6.00x102 cfu/ml). Seasonal pattern of variations was observed for water samples examined.

The Impact

The rising quality of life and high rates of resource consumption patterns had an unintended and negative impact both on the urban and rural environments and even on indigenous communities. Cities are now grappling with the problems of high volumes of waste, the costs involved, the disposal technologies and methodologies, and the impact of wastes on the local and global environment. This study is entitled Solid Waste Disposal Practices of the Atis (Aetas) of Boracay. The study was conducted to identify the Solid Waste Disposal Practices of the Atis in Boracay in terms of method of garbage storage and their methods of garbage disposal. It also seeks to identify activities/ programs implemented or practiced in the community to minimize improper waste disposal practices of every household in the community. The researcher to gather the information needed to be utilized a survey questionnaire. Interviews with 25 households and observations were conducted to further validate the authenticity of the data. Findings revealed that in terms of household garbage storage the respondents stored their garbage in a plastic bag, in an open container, and others pile it in the yard especially those biodegradable wastes. Concerning their garbage disposal practices, every household practiced proper segregation of waste. For their food waste, they put it in basket compost, while plastic containers, bottles, metals, and glass were segregated properly and disposed to a dumpsite through garbage collection. Trashes such as papers/cardboards were used for cooking by the Atis. Yard trimmings were used as compost as organic fertilizer. A once a week community cleaning is conducted by the Atis to maintain the cleanliness of their community where proper segregation of wastes was also monitored by the community organizer. In partnership with the Department of Agriculture Atis of Boracay were trained on basket composting to manage their biodegradable wastes. They were also guided by the policy of the Local Government Unit of Malay on proper wastes disposal.
