Public policies for contaminated site cleanup: evidence from a survey of the Italian public
Cleaning up contaminated sites is currently considered one of the most important environmental policy priorities in many countries. Remediation of contaminated sites is attractive because it reduces risks to human health and ecological systems, and brings a host of potential social and economic benefits. Public programmes are deemed necessary by the law and in practice to address contamination at ...

Comparisons of different risk-based approaches for managing contaminated sites
Over recent years, an increasing public and private concern has arisen over soil contamination following the closure of former industrialised sites or due to publicity over certain "scandals" (Love Canal in the United States) which occurred on former redeveloped industrial sites, affecting human health. Subsequently most countries have started a register of all industrial contaminated ...

Accelerating progress at contaminated sediment sites
The “top five actions” presented by Bridges et al. in “Accelerating Progress at Contaminated Sediment Sites: Moving from Guidance to Practice” (IEAM 8(2):331‐338) represent an important set of normative guidelines that could accelerate progress at contaminated sediment sites. An important next step is to use those guidelines to develop recommendations about good practices. This letter presents ...

A framework for establishing restoration goals for contaminated ecosystems
As natural resources become increasingly limited, the value of restoring contaminated sites, both terrestrial and aquatic, becomes increasingly apparent. Traditionally, goals for remediation have been set prior to any consideration of goals for ecological restoration. The goals for remediation have focused on removing or limiting contamination while restoration goals have targeted the ultimate ...

Building and breaking a bridge of trust in a Superfund site remediation
Trust is widely recognised as a key variable in perceptions and decision-making about environmental risks. However, most considerations of trust treat it as a simple two-agent relationship. Based on an analysis of a contaminated site cleanup in New Jersey, we identify a more complex construction of trust formed between multiple stakeholders. We refer to this construction as 'bridging'. In the ...

Brazil - updated soil contamination regulations
While Brazil has not changed its waste generator liability since adopting Law 6.938 in 1981, it has updated and altered requirements for generators. Most recently, the Brazilian National Council on the Environment (CONAMA) adopted CONAMA Resolution 420/2009, establishing guidelines and criteria for the management of contaminated sites. CONAMA Resolution provides for the creation of soil quality ...

Transforming Ecosystems: When, Where, and How to Restore Contaminated Sites
Chemical contamination has impaired ecosystems, reducing biodiversity and the provisioning of functions and services. This has spurred a movement to restore contaminated ecosystems and develop and implement national and international regulations that require it. Nevertheless, ecological restoration remains a young and rapidly growing discipline and its intersection with toxicology is even more ...

Transfer Your Environmental Risks to a Third Party
Remediation of contaminated sites often is costly and time-consuming, diverting scarce corporate resources from a company’s core operations. Moreover, the Sarbanes-Oxley Act and recent Securities and Exchange Commission and the Financial Accounting Standards Board rules and standards governing accounting for and reporting of environmental liabilities (e.g., FIN 47 Accounting for Conditional Asset ...

Research on the process-based risk evaluation method of groundwater pollution for contaminated site
A universal method to evaluate groundwater pollution risk with the site scale has not been established. The groundwater pollution risk is commonly evaluated by overlaying the results of groundwater vulnerability and pollution sources, but this method is inapplicable for contaminated sites. Considering the current supervision demands of groundwater pollution in China, this paper suggests a ...
