Contaminated Site Characterization with Kartotrak
Get acquainted with Geostatistics essential concepts for pollutant mapping and contaminated volume estimation
Nowadays, Geostatistics is more and more applied for soil pollution mapping and for risk analysis.
This course presents the basic concepts and methods of Geostatistics to achieve these goals. The subject matter ranges from variography to kriging and simulations for risk analysis.
A particular attention is paid to the integration of these methods for the characterization of contaminated sites: accounting for the historical data, sampling optimization, cartography of in situ pollution and estimation of contaminated volumes.
Methodological presentations followed by practical work using real cases. The focus is based on illustrations and contribution of the concepts presented using Kartotrak. Half of the course is dedicated to practical computer exercises in order to reinforce the previously presented theoretical notions.
Who should attend
The course is designed for practitioners confronted with the characterization of contaminated sites and who wish a practical introduction to geostatistical methods using Kartotrak.
- Illustrated presentation of current practices for the characterization of contaminated sites and estimation of contaminated volumes of soil. Advantages of using geostatistics over existing methods.
- Getting Started with Kartotrak.
Understanding and estimating the spatial heterogeneity of pollution
- Practical introduction to the concept of spatial variability. Operational implications for the feasibility of modelling for certain kind of pollution.
- How to quantify the spatial variability of a pollutant: calculation, interpretation and modeling of the variogram.
- Recommendations for sampling of potentially contaminated sites.
Predicting and mapping in-situ pollution
- Presentation of the usual methods of mapping the analytical data.
- Principle and properties of kriging in 2D/3D.
Quantifying and localizing the contaminated volumes
- Overall estimate of the volume of non-compatible land and its associated uncertainty, risk of non-compatibility of local mesh cleanup.
- Final inspection after remediation.
No prior knowledge of geostatistics is required. However a basic understanding of statistics is recommended.
This training can be followed by two days of workshop on your own data. Participation in these two days is optional. Click here for more information.
