Kartotrak allows Dekra to justify undoubtely their conclusions
Problematics “Our work is to provide our clients with the elements of decision they need to prepare site management plans for future remediation. Before we decided to include geostatistical approach in our projects, we were used to produce contamination maps based on very simple interpolation methods and empirical calculations. We needed a rational solution which enabled us to justify ...

Geochemical studies to delineate topsoil contamination around an ash pond of a coal-based thermal power plant in India
In the present study, an attempt was made to delineate soil contamination around the ash pond of a coal-based thermal power plant. The topsoil in the study area was found to be contaminated to varying degrees from ash disposal. The soil drawn from various profiles was largely contaminated by ash fall out, predominantly in the prevalent wind direction. Pb, Zn, Cu, Ni, Co, Mn, Cr, V and Ba were ...

Industrial experience feedback of a geostatistical estimation of contaminated soil volumes
Geostatistics meets a growing interest for the remediation forecast of potentially contaminated sites (both chemical/radiological): pollution mapping, contaminated volumes estimation, integration of auxiliary information, setup of adaptive sampling strategies. This interest has been supported in France by the GeoSiPol association (Geostatistics for Polluted Sites) created in 2004 and which is ...

A Procedure to assess Contaminated Soil Ecotoxicity
Abstract :Two polluted soil samples were assessed for both acute (Microtox®,Daphnia magna,Thamnocephalus platyurus) and chronic (Pseudokirchneriella subcapitata) toxicity, as well as for genotoxicity (Mutatox®). Bioassays were performed on soil water leachates and on soil solvent extracts to characterize not only the water soluble pollutants but also to evaluate less soluble pollutants or ...

Characterization Of A Deep Radiological Contamination: Integration Of Geostatistical Processing And Historical Data
Summary Emerging in the early 80’s, decommissioning is more than ever a major issue since hundreds of sites and facilities worldwide will end their operations over the next decades. Decontamination and remediation projects are all the more sensitive since they could last several years and turn out to be highly costly if not well-prepared. The key lies in an adequate contamination knowledge ...

Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach
A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with a mechanical high-speed mixer. ...

Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach
Received for publication August 12, 2008. A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with ...

How to Remediate under an Intersection with Horizontal Wells
Roadway intersections within urban settings are arguably some of the most challenging areas for subsurface remediation. Many consultants tasked with remediation of challenging sites such as these become frustrated by the inability of a vertical remediation system to influence the area of concern and/or they are anxious that they will not efficiently bring their clients’ sites to closure. ...

Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil
ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...
