ABSTRACT Net environmental benefits are gains in value of environmental services or other ecological properties attained by remediation or ecological restoration minus the value of adverse environmental effects caused by those actions. Net environmental benefit analysis (NEBA) is a methodology for comparing and ranking net environmental benefits associated with multiple management alternatives. A NEBA for chemically contaminated sites typically involves comparison of several management alternatives: (1) leaving contamination in place; (2) physically, chemically, or biologically remediating the site through traditional means; (3) improving ecological value through onsite and offsite restoration alternatives that do not directly focus on removal of chemical contamination; or (4) a combination of those alternatives. NEBA involves activities that are common to remedial alternatives analysis for state regulations and the Comprehensive Environmental Response, Compensation, and Liability Act, post-closure and corrective action permits under the Resource Conservation and Recovery Act, evaluation of generic types of response actions pertinent to the Oil Pollution Act, and land management actions that are negotiated with regulatory agencies in flexible regulatory environments (i.e., valuing environmental services or other ecological properties, assessing adverse impacts, and evaluating remediation or restoration options). This article presents a high-level framework for NEBA at contaminated sites with subframeworks for natural attenuation (the contaminated reference state), remediation, and ecological restoration alternatives. Primary information gaps related to NEBA include nonmonetary valuation methods, exposure-response models for all stressors, the temporal dynamics of ecological recovery, and optimal strategies for ecological restoration.

    ABSTRACT: Although in the last decades site remediation activities have received more attention and funds, the high cost required for the remediation projects and the limited resources available have resulted in a limited implementation of site remediation practices. Considering the recent economic crisis which has taken several countries worldwide, most contaminated sites could remain so. For instance, a large number of closed landfill sites are present in the territory and they could require a lot of money for remediation. It is obvious that the redevelopment of the site can play a major role in the sustainability of the remediation project. In this study a guideline was developed to evaluate the sustainability of site remediation and reuse projects. This guideline is based on a holistic approach which takes into account all the factors related to the site remedial actions, including political-decisional factors, social-economical factors, environmental factors, and technical factors. The developed guideline was applied to evaluate the sustainability of the remediation of a closed municipal solid wastes landfill site. In particular, it was proposed the reuse of the landfill restored site as a solar park. Obtained results have demonstrated that the restoration and land reuse projects is sustainable only when government subsidies are provided.

    ABSTRACT: The study examines the cost-effectiveness of two wastewater treatment models in China so as to provide a choice for policymaking. We choose the wastewater treatment system in China–Singapore Suzhou Industrial Park as case study because: 1) its sharing wastewater treatment plant (WTP); 2) its WTP was invested and operated by a private company; 3) its firms did not discharge illegal; 4) accessibility of data. The actual costs are determined by an extensive survey of 493 firms registered with the park. These data are also used to create a benchmark model assuming that each firm complies with environmental regulations by constructing its own WTP. The results show that sharing the WTPs greatly reduces the overall treatment cost. Furthermore, it reduces illegal discharges and improves the overall environmental performance of the park. Finally, it enforces cooperation among companies located in the park and creates a good image attracting more enterprises to join in.
