“…High Cu and Pb present in deeper soils have the potential to be released and exhibit harmful effects on the environment when the solubility of heavy metals is increased as soil properties change. For this reason, contaminated landfills must be managed and remediated in appropriate manners that ensure that contaminants remain harmless indefinitely 30.…”

The accumulation of heavy metals such as Cu, Zn, Pb, Cd, Cr, and Ni in water and soils in a new-built college town was investigated to demonstrate the effects of city construction on wetland ecosystem. Three sampling sites were chosen in wetland park (A), constructed wetland (B), and construction site (C), respectively. The results showed that the construction site C presented the highest accumulation levels of all six studied metals along soil profiles and hence had the highest eco-toxicity to environment. Sites A and B showed similar accumulation levels, whereas their concentrations were significantly lower than those at site C though seriously high Cd were also found in soils from both sites A and B and dangerous concentration of Pb in water was observed at site A based on several standards or background concentration values. However, when compared with other regions in Pearl River Delta, this college town could be counted as ''clean island'' which may be benefit from its isolate location away from urban center and the effective management to avoid pollution.

“…Phytoremediation is an attractive technology for landfill remediation and according to Kim and Owens (2010), it can stabilize soil while simultaneously remediating landfill leachate. Figure 8 illustrates the interaction between the soil and plant systems for leachate remediation in a CW.…”

“…Once the landfill leachate plume is monitored and risk assessment has been performed, then the management decision regarding leachate treatment can be taken. Already some comprehensive reviews on various leachate treatment technologies have been published (Alvarez-Vazquez et al, 2004;Deng and Englehardt, 2006;Foo and Hameed, 2009;Kim and Owens, 2010;Kurniawan et al, 2006b;Laner et al, 2012;Renou et al, 2008a;Wiszniowski et al, 2006). So we have included a brief but detailed description of only the most recent developments in this field, mainly in tabular form in Section 5 .…”

Landfills are the primary option for waste disposal all over the world. Most of the landfill sites across the world are old and are not engineered to prevent contamination of the underlying soil and groundwater by the toxic leachate. The pollutants from landfill leachate have accumulative and detrimental effect on the ecology and food chains leading to carcinogenic effects, acute toxicity and genotoxicity among human beings. Management of this highly toxic leachate presents a challenging problem to the regulatory authorities who have set specific regulations regarding maximum limits of contaminants in treated leachate prior to disposal into the environment to ensure minimal environmental impact. There are different stages of leachate management such as monitoring of its formation and flow into the environment, identification of hazards associated with it and its treatment prior to disposal into the environment. This review focuses on: (i) leachate composition, (ii) Plume migration, (iii) Contaminant fate, (iv) Leachate plume monitoring techniques, (v) Risk assessment techniques, Hazard rating methods, mathematical modeling, and (vi) Recent innovations in leachate treatment technologies.However, due to seasonal fluctuations in leachate composition, flow rate and leachate volume, the management approaches cannot be stereotyped. Every scenario is unique and the strategy will vary accordingly. This paper lays out the choices for making an educated guess leading to the best management option.

“…The use of dried biosolids as a fuel source for cement production is a valid option as they release an average of 6500 BTU/lb making them suitable to replace traditional fuel sources (Garcia, 2010). Kim and Owens (2010) conducted a review on the potential of biosolids to enhance phytoremediation in landfills due to the organic matter and nutrient content of the biosolids.…”

This review section covers journal articles and conference papers related to biosolids and sludge management that were published in 2010. The literature review has been divided into the following sections:  • Biosolids regulations and management issues,  • Biosolids characteristics and measurement including nanoparticles, hormones, pharmaceuticals and personal care products (PPCPs), metals and pathogens,  • Sludge treatment technologies including pretreatment and sludge minimization, anaerobic digestion, aerobic digestion, composting, conditioning and dewatering, and drying,  •Disposal and reuse covers combustion/ incineration, pyrolysis, and land application and reviews issues pertaining to nutrients, heavy metals, and synthetic organics,  • Odor and air emissions along with energy issues, and  • Risk analysis
