Geovariances helped NUVIA process to try Kartotrak
After several technical exchanges between NUVIA Process and Geovariances about the use of geostatistics for radiologically contaminated soil characterization, a guided evaluation was conducted to try Kartotrak on a real dataset. The first objective was to ensure that the resulting data was compatible with NUVIA Process georeferenced equipments before running Kartotrak workflow. Indeed, NUVIA ...

Geostatistics regains interest in the characterization of chemical soil pollutions
To evaluate the pollution impact, such characterization is usually based on various data that should be interpreted and analyzed with an estimation of related uncertainties. Geostatistics has been suitably applied in this framework for about fifteen years. Several Ph.D. theses have been dedicated to the subject, both for chemical and radiological pollution (see for instance this article in ...

EA spells out changes in contam land rules
Changes in regulations covering the disposal of contaminated soil have been mapped out by the Environment Agency for those working in the land remediation sector. The agency has published a fact sheet outlining imminent changes to the legal responsibilities of companies involved in the clean-up of brownfield sites. Liz Parkes, head of waste at the Environment Agency, said: 'Currently ...

Predicting amount of oil in contaminated soils
Scientists are reporting a new technique for mapping and testing oil-contaminated soils. Traditionally, samples need to be collected from the field and returned to a lab for extensive chemical analysis, costing time and money when neither is readily available during a clean-up operation. The new method can take measurements in the field and accurately predict the total amount of petroleum ...

Mapping human health risk in urban environments
A new study demonstrates how mapping software can be used to analyse data on heavy metal soil pollution in an urban environment. The researchers incorporated land use information to gain realistic estimates of potential risks to human health that could help inform land use planning. Human activities, including industrial manufacturing and road travel, contaminate the soil with heavy metals such ...

ASTM D7758 - 11 Standard Practice for Passive Soil Gas Sampling in the Vadose Zone for Source Identification, Spatial Variability Assessment, Monitoring, and Vapor Intrusion Evaluations
Passive soil gas samplers are a minimally invasive, easy-to-use technique in the field for identifying VOCs and SVOCs in the vadose zone. Similar to active soil gas and other field screening techniques, the simplicity and low cost of passive samplers enables them to be applied in large numbers, facilitating detailed mapping of contamination across a site, for the purpose ...
