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 ...

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 ...

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 ...

The Small Business Liability Relief and Brownfields Revitalization Act, (“Brownfields Amendments”), Pub. L. No. 107-118, enacted in January 2002, amended the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), to provide important liability limitations for landowners that qualify as: (1) bona fide prospective purchasers, (2) contiguous property owners, or (3) innocent ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Received for publication October 31, 2007. A legacy of lead and silver mining in its headwaters left Lake Coeur d'Alene, Idaho with a sediment body that is highly reduced and contains up to 100 g kg–1 iron and a smaller fraction of chemically active sulfide phases. The dynamic character of these sulfides and their importance for the sequestering of contaminating trace elements prompted this study ...

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 ...

Site Summary ORC Advanced releases a maximum of 17% by weight of oxygen into a saturated area. Such a high release of oxygen can effectively reduce high concentrations of contaminants, allowing for successful bioremediation of source areas. A petroleum contaminated site in Virginia had TPH and MTBE contamination at levels much higher than MCLs. The source area contained concentrations of TPH and ...

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 ...

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 ...

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 ...

Within the increasing (legislative and applicative) attention to absolute risk analysis for contaminated sites at Italian level, as a University research study and exercise, the definable 'ARA-CoSSSLs' absolute risk analysis approach for human health protection ('Absolute Risk Analysis for Contaminated Sites', on 'Soil Screening Levels' basis) has been derived (as an initial, simplified version) ...

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 ...

The aerobic degradation of hexachlorobenzene (HCB) by an acclimated microbial community which isolated from a contaminated site and acclimated in our laboratory was investigated. The enriched microbial community was capable of biodegrading HCB when cultivated in minimal salts medium and supplied HCB as the sole carbon source. The efficiencies of microbial community in the degradation of HCB under ...
