Who will do the Cleanup? (Contaminated Sites Report 2007)

To better understand Canada’s current capacity to meet this unique labour demand, ECO Canada undertook this study in early 2006. Our work was guided by a 29-member National Steering Committee from government, industry, and academia. In addition, a full-day National Forum on Contaminated Sites was held in Vancouver on March 28, 2006 to gain support and gather comments on the project from ...

Spatial Patterns and Rankings of Contaminant Concentrations in Herring Gull Eggs from 15 Sites in the Great Lakes and Connecting Channels, 1998–2002

Mean values of eight contaminants in Herring Gull (Larus argentatus) eggs were calculated for 15 Great Lakes sites for the 5 year period 1998–2002. The sites were ranked according to the concentrations of each of seven compounds relative to fish flesh criteria for the protection of piscivorous wildlife, and a single overall rank of contamination was calculated for each site. Based on this ...

When Supply does not Meet Demand (Contaminated Sites Report 2008)

During the next few decades, federal, provincial, and municipal governments, as well as the private sector, will commit large sums of money to clean up contaminated sites across Canada. A combination of regulatory and economic drivers will keep the sector buoyant, resulting in a strong demand for labour to work on contaminated sites. Between 2004 and 2019, the federal government has committed up ...

Fast bioremediation of a hydrocarbon contaminated site

The use of bioremediation has been demonstrated to be a very effective treatment technology for a hydrocarbon contaminated site within a month of starting. In addition to selection and preparation of an appropriate microbial inoculum the other key considerations were effective mixing, addition of suitable nutrients and maintenance of soil moisture levels. Careful management of all these ...

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 ...

A fuzzy multi-criteria decision analysis approach for the management of petroleum-contaminated sites

This paper presents an effective Fuzzy Multi-Criteria Decision Analysis (FMCDA) approach for contaminated site management. The development was based on: selecting eight criteria for remedial alternative evaluation and determining the weight of criteria importance under uncertainty; addressing various uncertainty issues in remedial alternative assessment process using a fuzzy-set approach based on ...

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 ...

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 ...

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 ...

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 ...

NJDEP issuing remedial priority scores for contaminated sites

Very shortly, the New Jersey Department of Environmental Protection (NJDEP) will be issuing letters to responsible parties containing a draft Remedial Priority Score (RPS) for their particular site. It is unclear how the rankings will be used, but the RPS system has been described as a tool to sort sites out for further discussion. The Site Remediation Reform Act (SRRA), N.J.S.A. 58:10C-1 et seq. ...

Long‐term water quality data explain inter‐population variation in responsiveness to stress in sticklebacks at both wastewater effluent‐contaminated and uncontaminated sites

The magnitude of the corticosteroid response to a standardised stressor varied in proportion to the concentration of effluent in three‐spined sticklebacks (Gasterosteus aculeatus L.) captured downstream of 10 wastewater treatment works (WWTW). However, at 9 sites with no upstream WWTW input inter‐population variation in the reactivity of the stress axis occurred across a similar range to that ...

Mapua, New Zealand - Case Study

In collaboration with the New Zealand Ministry for the Environment and Tasman District Council, EDL undertook its largest project to date at the Fruitgrowers Chemical Company site in Mapua. 8,650 m3 of soil heavily contaminated with Lindane, DDT, Dieldrin, and Aldrin was treated at what was known as country’s most contaminated site. All soil was successfully remediated to levels below soil ...

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 ...

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 ...

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 ...
