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 ...

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 ...

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 ...

Geostatistical modelling of ground conditions to support the assessment of site contamination
The pattern of ground contamination across a site depends on the historical pattern of contaminant releases at the surface and the redistribution and the fate of contaminants below the surface. Using these concepts a new site assessment approach (assessment modelling) is proposed based on the development of three stochastic models: a model of the physical structure of the ground materials beneath ...

Risk assessment and brownfields-determining exposure to site contaminants
The USEPA’s Brownfields Program was developed to facilitate the rehabilitation of contaminated property for re-development. EPA has set forth criteria that must be met for a revitalized property to be used for residential, commercial or industrial purposes. The main thrust of these criteria is the long-term protection of residents or visitors (including shoppers and business employees). As ...

Bioremediation Consulting Inc (BCI) develops an anaerobic chloroform-degrading culture
BCI’s newest culture is a microbial mixture (consortia) which can transform chloroform (CF) to dichloroemthane (DCM), a transient intermediate which is then converted to a non-chlorinated product. We have demonstrated that the culture can dechlorinate at least 10 ppm of chloroform. Dechlorinating Bacteria in BCI Cultures. To address single compounds or a mixture of chlorinated ethenes, BCI ...

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 ...

The (Environmental) Science of Investigation: Interactive Forensics Training Helps Professionals Solve Petroleum Contamination Cases
When a site is contaminated with petroleum products, there are many questions. How did it happen? When did it happen? And, most importantly, who is responsible for paying to clean it up? This fall, Rutgers University’s Office of Continuing Professional Education (OCPE) will help professionals answer those questions in its completely revamped Environmental Forensics training ...

BC Protocol 4 Background Concentrations in Soil
British Columbia’s Protocol 4 is applied in situations where the concentration of substances exceeds the desired numerical soil standards described under Contaminated Sites Regulation (CSR). It is applied to investigate and remediate contaminated sites to conduct soil relocation in such areas. The BC Protocol 4 outlines the procedures which are used to determine soil background ...

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 ...

Brownfield Development Will Help the Global Housing Crisis
Brownfields no longer have to be unused, derelict sites. Land contaminated with explosive materials, hydrocarbons and other organic contaminants, can be safely reclaimed for residential and mixed-use purposes to help address housing and real estate shortages. And contaminated soil no longer has to be trucked to a landfill where it will create future environmental liabilities. Treating the ...
