More information
Note that this one-day seminar is also available in French.
Objective
- Get introduced to relevant geostatistical solutions for the characterization of contaminated sites: quality control and exploratory data analysis, analysis of the spatial heterogeneity, estimation of in-situ pollution and of the contaminated volumes, quantification of related uncertainties.
- Understand the relevance of geostatistics, its added value and conditions for implementation.
Format
Methodological presentations illustrated with practical examples on real cases involving various types of pollution, both chemical and radiological, leak from a source, reworked fills, etc.. These illustrations involve several environments: soil, sediment, plants (concrete).
Who should attend
Decision-makers, engineers and technicians involved in the characterization or remediation of potentially contaminated sites.
Seminar content
- Current practices
- Presentation of classical approaches implemented for the sampling of potentially polluted sites and the estimation of contaminated soil volumes.
- Pros/Cons and underlying assumptions of these approaches.
- Understanding and estimating the spatial heterogeneity of pollution
- Practical introduction to the concepts of heterogeneity and spatial variability of pollutants. Operational consequences on the feasibility of given remediation techniques.
- How to quantify the spatial variability of a pollutant: calculation and interpretation of the variogram.
- Recommendation for the sampling of potentially polluted sites.
- Predicting and mapping in-situ pollution
- Presentation of common deterministic interpolation methods.
- Introduction to the kriging and its advantages: integration of the spatial variability, quantification of the attached uncertainty.
- Accounting for auxiliary information: site history, qualitative observations and quantitative measurements.
- Quantifying and locating contaminated volumes
- Risks attached to the use of interpolation methods for estimating contaminated volumes.
- Practical introduction to the stochastic simulations approach.
- Presentation of results: global estimation of contaminated volumes and the attached uncertainty, local risk of exceeding cleanup levels.
