Geostatistics applied to site characterization and remediation

The global economy and success of contaminated site characterization and remediation projects and the environmental exposure are strongly impacted by the quantity of material to be excavated, treated, then re-used or eliminated. Appropriate data acquisition, reliable mapping, precise waste categorization, and uncertainty assessment are key issues for achieving successful projects.

Whatever the contamination type (chemical or radiological) you are facing and the impacted medium (soil, concrete, sediments or groundwater), geostatistics provides you with the most efficient framework to meet these goals and improve your decision-making process.

When using a "sniffing truck" with MIP probes to search for pollutions by volatile organic pollutants, thousands of data are collected. With Kartotrak, the management of all these data becomes a childlike simplicity and the graphical representations of results more relevant.

Data Quality Control

Before starting an evaluation of the contamination leading to decision-making tools for site clean-up, it is essential to ensure data quality. Thus, based on solid and reliable foundations, uncertainties occurring during the different steps of the decision process will be better controlled and the final quality of the project improved.

The objective of this white paper is to assess at best the validity of the data through visual, statistical and geostatistical basic tools before going further into their analysis.

Dose Rate Mapping

The objective of any serious mapping is to obtain a realistic and reliable image of the studied phenomenon. Concerning dose rate, maps are often derived from punctual measurements interpolated using deterministic methods. Sometimes, the choice of the inverse distance squared weighted interpolation is wrongly justified by the fact that the dose rate issued from a punctual source is theoretically inversely proportional to the squared distance between the source and the measurement point.

Through this white paper, find out why this inverse distance squared weighted interpolation is not the appropriate method for dose rate mapping and why the geostatistical approach by kriging is the solution for a quality and reliable mapping.
