Generation of solid waste precedes the surge of urbanization. The earliest waste dumping is recorded in Greece as early as 500 BCE, the conservancy workers in France, wastewater treatment in London, and aqueduct systems in oriental civilizations. The magnitude of waste has been compounding annually with the rise of global population, urbanization, and economic growth. Waste has been overtly and irresponsibly dumped in inland water bodies and the wetlands around it causing inherent damage to the fluvial, pond, or riverine ecosystems. The United Nations has declared this decade to be for ecosystem restoration, and hence, this chapter intends to ponder and establish the concerns of health, species modification, ecosystem endangering, pollution of the surface and subsurface water, impact on the vegetation along the water stretches, to name a few. The objective of this chapter is to evaluate the impact on the ecospheres while arriving at sustainable restoration options.

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 analysis of technical measures allowing to control the municipal solid waste disposal (MSW) landfill with the purpose of emission reduction at different stages of the life cycle is presented. The review of the latest research in the field of implementation of technical measures at the operational and aftercare period is conducted: controlled water infiltration, collection of biogas, aeration of the landfill body, installation of methane oxidation cover systems. It is substantiated that the choice of a technical measure for management of the disposal for MSW landfill should be carried out taking into account the ultimate goal: reduction of biogas and leachate emissions, acceleration of waste decomposition processes, reduction of the impact of the landfill on environmental objects at the aftercare period. Criteria for choosing technical measures for reduction biogas and leachate emissions, boundary conditions and peculiarities of their implementation at different stages of the life cycle of the landfill have been established.

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.

Populated coastal areas worldwide have a legacy of numerous solid waste disposal sites. At the same time, mean sea level is rising and likely to accelerate, increasing flooding and/or erosion. There is therefore concern that landfill sites located at and near the coast pose a growing risk to the environment from the potential release of liquid and solid waste materials. This paper aims to assess our present understanding of this issue as well as research and practice needs by synthesizing the available evidence across a set of developed country cases, comprising England, France, Germany, the Netherlands, and the United States (Florida). Common insights gained here include: (1) a lack of data and limited appreciation of waste release from coastal landfill as a potential problem; (2) recognition of the scale and diversity of coastal landfill waste within a range of generic settings (or situations); and (3) a lack of robust protocols that allow the impact of different categories of waste release to the coast to be assessed in a consistent and evidence-based manner, most particularly for solid waste. Hence, a need for greater understanding of the following issues is identified: (1) the amount, character and impact of waste that could be released from landfill sites; (2) the acceptability and regulation of waste eroding from coastal landfills; (3) present and future erosion rates at landfill sites suggesting the need for more monitoring and relevant predictive tools; (4) the full range of possible management methods for dealing with waste release from landfills and the science to support them; and (5) relevant long-term funding mechanisms to address this issue. The main focus and experience of current management practice has been protection/retention, or removal of landfills, with limited consideration of other feasible solutions and how they might be facilitated. Approaches to assess and address solid waste release to the marine/coastal environment represent a particular gap. Lastly, as solid waste will persist indefinitely and sea levels will rise for many centuries, the long timescale of this issue needs wider appreciation and should be included in coastal and waste policy.

Over the years, the generation of municipal waste in India has increased significantly. Solid waste management has become an important issue due to poor waste management practices affect public health and urban services. Municipal waste generation increases with increasing population, urbanization and industrialization. Municipal solid wastes disposal is a stinging and widespread problem in many developed and developing countries, in both urban and rural areas. Municipal waste management solutions must be economically sustainable, technically feasible, social, legally acceptable and environmentally friendly. Sanitary landfilling is popular in most countries because of the due to its relatively low cost and low technical requirements This paper mainly review on need to dispose of municipal waste, sanitary land filling method of disposal of MSW, Evaluation of the impact of landfills on the environment such leachate, land fill gases (LFG), land fill fires (LFF), strategies for effective management of sanitary landfills and sustainable measures (reduce, reuse and recycle) to minimize the amount of waste that ends up in landfills. Keywords: Municipal solid waste, Sanitary landfill, leachate, land fill gases (LFG) and land fill fires (LFF).

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.
