“…We also observed higher peak concentrations of COD in this study (95,333 mg/L) compared with a COD concentration of 20,414 mg/L observed in the natural leachate from FMD disposal sites [12]. Most of the contaminant concentrations reported in the current study compare favorably with a field study investigating freshly produced leachate from a municipal solid waste landfill in Greece in which daily waste deposits contained nearly 50% food wastes [18].…”

“…Concentrations of total phosphorus detected in previous study of carcass decomposition remained at approximate 1,200 mg/L [13] for the pure leachate. In the Greece municipal solid waste landfill, level of total phosphorus ranged from 1.6 to 655 mg/L in the leachate collected next to the deposition area [18]. However, the range of TP concentration shifted to 1.27 to 19.9 mg/L in the old leachate which stayed at the lowest part of the landfill for several months, subjected to natural attenuation/stabilization but not oxygenation [18], which is close to the level of TP detected in this study.…”

In the present study, the carcasses were surrounded by soil and soil adsorption may be one reason for the low concentrations of phosphorus detected in leachate in the current study.…”

Among the conventional disposal methods for livestock mortalities, on-farm burial is a preferred method, but the potential water quality impacts of animal carcass burial is not well understood. Typically, on-farm burial pits are constructed without liners to prevent percolation of leachate into soil and groundwater. To date, no information is available on temporal trends for contaminants in leachate produced from livestock mortality pits. In our study, we examined the concentrations of conventional contaminants (electrical conductivity, COD, TOC, TKN, TP, and solids) as well as some antimicrobials and steroid hormones for a period of 20 months. High concentrations of conventional contaminants were detected in leachate collected from the field burial pits. In addition, 17β-estradiol and monensin were also observed at maximum concentrations of 20,069 ng/L and 11,980 ng/L, respectively. Estimated mass loading of total steroid hormones and veterinary pharmaceuticals were determined to be 1.84 and 1.01 µg/kg of buried cattle carcass materials.

“…This depends on several factors, such as the characteristics of the refuse/waste, nature/strength of the wastewater type, operation protocol (organic loading rate, leachate recirculation), landfill age as well as physical, chemical and microbial processes altering wastewater composition during infiltration through the landfill body (Rahim and Watson-Craik, 1997;Percival and Senior, 1998;Tatsi and Zouboulis, 2002). It has been reported that if co-disposal is effectively controlled, the leachate produced should not differ greatly from the landfill leachate (Percival and Senior, 1998).…”

a b s t r a c tThe present paper focuses on a largely unexplored field of landfill-site valorization in combination with the construction and operation of a centralized olive mill wastewater (OMW) treatment facility. The latter consists of a wastewater storage lagoon, a compact anaerobic digester operated all year round and a landfill-based final disposal system. Key elements for process design, such as wastewater pretreatment, application method and rate, and the potential effects on leachate quantity and quality, are discussed based on a comprehensive literature review. Furthermore, a case-study for eight (8) olive mill enterprises generating 8700 m 3 of wastewater per year, was conceptually designed in order to calculate the capital and operational costs of the facility (transportation, storage, treatment, final disposal). The proposed facility was found to be economically self-sufficient, as long as the transportation costs of the OMW were maintained at 4.0 V/m 3 . Despite that EU Landfill Directive prohibits wastewater disposal to landfills, controlled application, based on appropriately designed pre-treatment system and specific loading rates, may provide improved landfill stabilization and a sustainable (environmentally and economically) solution for effluents generated by numerous small-and medium-size olive mill enterprises dispersed in the Mediterranean region.

Sanitary landfilling is the most widely used method for disposing of urban solid wastes around the world. The extensive use and the public awareness of this disposal method have raised concerns, over the negative environmental impacts and the pollution potential that this practice creates, as well as by the by‐products of landfills (e.g., leachates, biogas, odors, etc.). Among them, leachates are considered the most important environmental burden. Depending on the composition and extent of decomposition of the disposal of refuse, as well as on the hydrological parameters existing in the landfill site, leachates may become highly contaminated wastewaters. Landfill leachate , as defined in the U.S. Environmental Protection Agency Code of Federal Regulations (CFR) Title 40, Part 258.2, is the liquid that has passed through, or emerged from the disposal of solid wastes and contains soluble, suspended, or miscible materials from these wastes. Over time, the seepage of water through the landfill mainly from precipitation increases the mobility of pollutants and the potential for transferring them into the surrounding environment. As water passes through the layers of disposal of solid wastes, it may “leach” pollutants from them, moving them deeper into the soil.
