  • I) Finding the right EU funding programmes for your R&D project idea and writing a competitive proposal

     

    by Innovayt (Kenneth Glarbo/Michael Holbech)

    10 am - 12 am

    This mini course will give you a quick introduction to the various EU funding opportunities available for companies, scientists and public organisations for R&D and innovation related projects within the Horizon 2020 programmes. Furthermore, the course will provide participants with best practice guidance on how to write a winning proposal, based on experiences from more than 200 proposals under FP7 and Horizon 2020. Finally, participants can sign-up for a 1:1 meeting to discuss match of project idea with relevant EU programmes. Innovayt is a privately held consultancy company who, since 2006, has specialized in writing application towards FP7 and Horizon 2020 within all technology areas, including soil remediation.

  • III) Environmental site investigations. Drilling methods and field procedures

     

    by John Bastrup (GEO)

    2 pm - 6 pm

    This short course is focusing on presenting examples on quality drilling and sampling methods, logging, and various pump test methods. The different testing techniques in soil and ground water is based on Geo´s huge field experience and long term subsurface expertise. The last many years the development of investigation techniques have been concentrated on -the often clayey- overburden. But a large part of the ground water resource around Copenhagen is found in limestone and chalk aquifers. These aquifers have double porous properties, which have a profound impact on contaminant transport. Investigation of soil or groundwater contaminants in these aquifers require high resolution measurements such as geophysical logging, discrete level sampling and coring to obtain relevant samples and high resolution understanding of the geological conditions. We will concentrate on state of the art on these investigation methods focusing on high quality of the work.

     

    Course Agenda

    1. Overview of the Danish geology including a brief hands-on session with emphasis on various soil types. Get a basic understanding of the different soil types, as well as a basic knowledge to distinguish the types of soil from each other. The different soil characteristics related to environmental matters such as how to optimize investigations and remediation will be discussed.
    2. Environmental site investigations. Drilling methods, investigation and field procedures. Drilling at contaminated sites or at potential polluted sites poses special challenges to drilling works as it may not cause pollution to spread to uncontaminated layers and as the collected and tested soil and water represents the exact levels. We present the challenges and solutions encountered when drilling at contaminated sites as well as the Danish legislation governing drill works. Different drilling and investigation methods will be described and tools and equipment will be shown.
    3. Geophysical logging and investigation methods in fractured rocks. The application of geophysical logging in environmental studies related to assessment and mapping of groundwater contamination is becoming more and more common as the complexity of the studies increases. Particularly in the double porous formations, such as limestone, it makes sense to survey the direction of main groundwater flow zones in order to target later remediation approaches. As a supplement to soil samples from corings, the use of different discrete level specific testing methods, flow logs and televiewer logging is of interest, but other logging methods can also be used in order to discern valuable geological and hydrogeological information. We will review the general application of borehole logging and investigation methods in open and screened boreholes related to environmental studies. We will focus on what will work under different conditions, method limitations, and what additional information the use of geophysical logging and other investigation methods may contribute to the project.
    4. Pumping test. Properly performed pumping tests provide valuable knowledge about the formation’s hydraulic parameters, which form an important base for working with transport modeling and risk assessments. But how should a pump tests actually be conducted in order to be cost effective and provide knowledge? What requirements are there to the design of the pumping well, well development etc. What factors may affect the quality of pumping tests? Will you need additional monitoring wells or you can do entirely without? How will you interpret the results? This and much more is included in a session focusing on practical pumping tests and the subsequent data interpretation for further use in contaminated groundwater risk assessments.

     

  • IV) An Overview of Geostatistics for Contaminated Site Characterization

     

    by Hélène Demougeot-Renard (eOde) and Nicolas Jeannée (Geovariances)

    10 am - 6 pm

    As you are involved in the characterization or the remediation of contaminated sites, you regularly face the following issues:

     

    • How to optimize a sampling plan and assess the samples’ representativeness?
    • How to integrate all available data in order to improve the contamination understanding?
    • How to properly model the change of scale between sampling and remediation mesh?
    • How to precisely locate contaminated soil volumes or pollutant masses?
    • How to quantify uncertainties related to the delineation of impacted areas, while integrating geological heterogeneities?

     

    During the seminar, you will understand why geostatistics provides relevant methods to address these issues and how they can be applied in operational contexts.

     

    Format

    Methodological talks illustrated with practical examples on real cases involving various types of pollution: chemical or radiological, leak from a source, reworked fills, etc. These examples involve several environmental media: soil, sediment, facilities (concrete). Ample time is allotted for discussion and feedback with participants.

     

    Seminar content

    • Understand and assess the spatial heterogeneity of pollution

    • Presentation of the classical approaches implemented for characterizing potentially polluted sites and for predicting contaminated soil volumes, as well as assessing their compatibility for future use.
    • Pros/Cons and underlying assumptions of these approaches.
    • Practical introduction to the concepts of heterogeneity and spatial variability of pollutants. Operational consequences on the feasibility of given remediation techniques.
    • Recommendation for the sampling of potentially polluted sites.

    Predict and map 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.
    • Taking into account auxiliary information: site history, qualitative observations and quantitative measurements.

    Quantify and locate contaminated volumes

    • Risks attached to the use of interpolation methods for estimating contaminated volumes.
    • Practical introduction to stochastic simulations.
    • Presentation of results: global estimation of contaminated volumes and attached uncertainty, local risk of exceeding cleanup levels.
