`Standards are desperately needed for plastic and pesticide contamination in soil´

In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

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 ...

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 ...

Hazardous waste and not, Baioni-Dicatech system

The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

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 ...

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 ...

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 ...

In-Situ Bioremediation Treats Contaminants at a Disposal Site

Site Summary A TCE-contaminated plume developed from buried drums containing organic solvents on the former Duluth Airbase. Soil excavation took place in the early 1990s and a total of 1,925 yds3 of soil were treated through land farming. A few years later, site assessment activities uncovered a VOC plume in groundwater and further monitoring revealed the breakdown of TCE to daughter products ...

Modeling Leachate Contamination and Remediation of Groundwater at a Landfill Site

Leachate contamination of an aquifer from a landfill sitewas simulated using the groundwater flow and transport model SUTRA developed by the U.S. Geological Survey. The model calibration was performed by spatially adjusting the hydraulic conductivity in order to capture the measured hydraulic head spatial variation and then by adjusting the dispersivity and porosity match the measured chloride ...

Quantitative risk assessment for contaminated sites in Spain

Environmental Quantitative Risk Assessment is one of the key factors in the Decision Making Process for contaminated sites. Numerous decisions have to be made before, during and after conducting a quantitative risk assessment.Risk assessment is based on the information gathered previously: Historical information (Phase I) Site characterization (Phase II) Toxicological ...

Contaminated Water

Treatment of Contaminated Mine Water Discharge Recent estimates have suggested that in the UK 2,500 km of streams and an area of 9,000 km2 of groundwater bodies are at risk of failure of Water Framework Directive Objectives due to mine water pollution (Jarvis & Rees 2004). For over two decades the Loughor Estuary in South Wales, which carries SSSI status, had been ...

Identification of source of heavy metal contamination in a site - a case study

Accidental spills and improper disposal of industrial effluent/sludge containing heavy metals onto the open land or into subsurface result in soil and water contamination. Detailed investigations are carried out to identify the source of contamination of heavy metals in an industrial suburb near Bangalore in India. Detailed investigation of ground water and subsurface soil analysis for various ...

Development of quality objectives for contaminated sites: state of the art and new perspectives

Local soil contamination, mainly associated with industrial facilities (both in operation and after closure), uncontrolled (industrial and/or municipal) waste landfills, mining and diffused leaching underground storage tanks and pipelines, is an actual and relevant environmental priority in Europe. Different approaches have been applied in the European countries during the past few years to ...

A framework for screening sites at risk from contaminants of emerging concern

Trace levels of a variety of currently unregulated organic chemicals have been detected in treated wastewater effluents and surface waters that receive treated effluents. Many of these chemicals of emerging concern (CECs) originate from pharmaceuticals and personal care products that are used widely and that frequently are transported “down the drain” to a wastewater treatment plant (WWTP). ...

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 ...

Development of an on-site Fe0 system for treatment of copper- and zinc-contaminated roof runoff

The objective of the present work was to develop an on-site Fe0 system for treatment of metal-contaminated roof runoff. Breakthrough experiments were performed under laboratory flow-through conditions using runoffs that have varying water quality parameters. Phase analyses and the chemical-equilibrium model were employed for describing the removal mechanisms. ...
