1. Environmental forensics techniques: an added value to better understand soil & groundwater contaminations

Time: 8.30–11.30

Room: Gorilla 3, FMCCA, Antwerp

Duration: 3 h;

Presenters: Pieter Schrooten en Wibo: Samuel Van Herreweghe

The training will explain the basics of several environmental techniques and how they can provide additional information to better understand the origin of contaminations or the processes that influence soil & groundwater contaminations. The information obtained from these techniques can be crucial in defining remedial liabilities. It can help in defining an optimised, more sustainable remedial approach or it can provided the necessary evidence to terminate monitoring projects. The applicability and limitations of different techniques will be illustrated by cases.

2. PFAS: overview

Time: 11.30–14.30

Room: Gorilla 3, FMCCA, Antwerp

Duration: 3 h

Presenters: Ian Ross, Tessa Pancras

In this short course an overview will be given on the characteristics and behaviour of the different PFAS components. Based on this investigation methods, analytical techniques and remediation techniques will be discussed

3. Phytoremdiation

Time: 14.30–17.30

Room: Gorilla 3, FMCCA, Antwerp

Duration: 3 h

Presenters: Jaco Vangronsveld, Nele Weyens (U. Hasselt)

In this short course, the basics of phytoremediation will be explained, including the types of contaminants that can be dealt with. Several case studies will be included.

4. In Situ Thermal Desorption – What is the state-of-the art today

Time: 8.30–12.30

Room: Gorilla 5, FMCCA, Antwerp

Duration: 4 h

Presenters: J. Haemers (Haemers Technologies) and M. Vandenbrand (TRS Europe)

A technical review of Thermal Conductive heating and Electrical resistive heating technologies.

The course will cover both theoretical aspects of the various technologies, their practical applications and concrete do's and don'ts for applying TCH and ERH-type projects.

It will help consultants, problem owners, regulators better understand the limits and possibilities of In Situ Thermal Desorption, with practical tips needed to design and/or recommend those technologies, understand the treatable pollutants, treatment times, performance drivers and cost elements.

5. Mass flux and mass discharge measurement in groundwater: use and methodology

Time: 13.30–17.00

Room: Gorilla 5, FMCCA, Antwerp

Duration: 3 h

Please bring: pen & paper, notebook

Contact: Goedele Verreydt, iFLUX

This workshop is interesting for advanced researchers and practitioner as well as a good starting point for beginners.

Flux measurements as missing piece of the complex contamination puzzle: What – Why – How?

Most decisions regarding contaminated groundwater sites are driven by contaminant concentrations. These decisions can be improved by also considering contaminant mass discharge and mass flux. Mass discharge and flux estimates quantify source or plume strength at a given time and location. Consideration of the strength of a source or solute plume (i.e., the contaminant mass moving in the groundwater per unit of time) improves evaluation of (stimulated) natural attenuation and assessment of risks posed by contamination to downgradient receptors, such as living areas, supply wells or surface water bodies.

At this workshop you will learn everything about the use of groundwater and contaminant flux measurements during soil and groundwater research. We consider the principle of a flux measurement (why it is more than just a time-averaged concentration?) and how to apply it specifically in both the investigation and remediation phase. We aim for a hands-on course based on real cases and different approaches (making use of Passive Flux Sampling, Point Velocity Probe and Finite Volume Point Dilution Method) while we will listen to your experience and questions concerning the mass flux concept.

The course will be given in cooperation with Prof. Poul Bjerg (DTU), Prof. Serge Brouyère (ULg). Figure: iFLUX

Target group is environmental professionals working either as consultant, industry stakeholder, or authority, and working with complex groundwater contaminant projects. No previous pre-know how required.

Within the scope of environmental sampling, a number of novel passive sampling techniques have emerged over the recent years, however still with limited use in routine groundwater remediation projects. With focus on groundwater applications, the current pre-course will provide an in-depth and “hands-on” presentation of SorbisenseTM passive sampling technique. The sampling units are designed specifically for use in groundwater investigations, and with the method an accumulated time-averaged concentration is obtained, rather than a single snapshot from conventional groundwater samples. Also multi-level sampling along the length of a well screen allows for an exact assessment of risks and the effects of remediation. A number of cases will be presented both for classic and emerging pollutants, hereunder PFAS.

With the focus on air sampling a new technique is now also available on the European continent regarding passive sampling with canisters. The canisters are depressurized stainless steel containers, hermetically sealed and used to collect air samples or Volatile Organic Compounds (VOCs). Their inner surface is rendered inert by an electropolishing step combined with a chemical deactivation step. The canister operates on the principle of a pressure differential between the atmospheric pressure and the inside of the canister, which allows the air to be drawn to be driven inside the canister which is under vacuum. The molecules to be analyzed (analytes) remain trapped in the gas matrix inside the canister itself.

7. UXO: Procedure and practice (cancelled)

Time: 2–5 pm (duration: 3 h)

Organiser: Kim Deroose & Charlotte Derez (Adede)

This workshop is interesting for advanced researchers and practitioner as well as a good starting point for beginners.

This workshop will focus on the general procedures for handling UXO. Using the Belgian guideline for UXO as a basis we will walk through the full process of remediation safety issues posed by UXO on a site. This involves:

-          Desk-Based research;

-          Survey;

-          UXO Identification;

-          Supervision of planned works;

-          And the free of explosives certificate.

Each step of the process will be explained with special attention to how the various steps contribute to cost-reduction, project efficiency, and safety for both on-site personnel and equipment.

The workshop will be given by personnel with practical experience in historical research, geophysics, and UXO management.
