Meeting Room 20 SpS 1D.4S Holistic water planning: How do we protect groundwater in Denmark? Organizers: The Danish Knowledge Exchange Group Chair: Rolf Johnsen, Central Denmark Region The groundwater resource in Denmark accounts for 99 % of the country's drinking water supply, and it is a major source of irrigation water for agricultural land. This means that, in Denmark, we have a very long tradition of managing and protecting our groundwater aquifers from overexploitation and contamination. The drinking water supply is based on a decentralised water supply structure, with many small and large suppliers. The water supply system in Denmark is characterised by having very simple water treatment, where primarily iron and manganese are separated out in sand filters. After this simple water treatment, the water can then be distributed to the consumers. This is possible because the groundwater resource is generally uncontaminated in Denmark due to a plentiful natural resource with a relatively long transport time from surface to aquifer, and because of our long tradition for generation of knowledge about the groundwater, as well as Danish society's general pro-active approach to the protection of the groundwater. For example, there is a political tradition for regulating the agricultural sector's use of fertiliser and pesticides. There is also a tradition for granting resources to the public sector, so it can deal with ownerless contamination that threatens the groundwater resource, and conduct the investigations and clean-up operations mandatory when existing industries contaminate the soil and groundwater. The Danish model is builds on a tradition of planning based on the protection of the resource and the natural environment in collaboration with, and with a great deal of trust between, the authorities and stakeholders. The session will provide an insight into why and how such considerable financial resources (approx. EUR 360 million) have been used in the last 15 years to map the locations of groundwater aquifers and the transport routes for groundwater formation in Denmark. The work in implementing the protection of groundwater is carried out by the municipalities, which are the local groundwater resource authorities. The session will also provide insight into how work in the last 30 years has focused on mapping, studying and preventing contamination from industrial point sources that threaten the groundwater. The session will end by a discussion with the audience putting the benefits and future challenges into perspective, in relation to mapping and managing the groundwater resource, and comparing the "Danish model" with other countries' management systems.

Drivers/political incentives for the "Danish model" on groundwater mapping and protection(put into perspective, focus on legislation + enforcement) (10 min). Martin Skriver, the Danish Nature Agency.

Meeting Room 18 SpS 2.2S “Towards Urban Land Management 2065” – Brownfields the secret weapon for sustainable cities Organizers: Maaike Blauw, Linda Maring (Deltares, NL) Hans van Duijne (Deltares/WU, NL) on behalf of EU FP7 HOMBRE and EU Snowman Balance4P consortium Brownfield sites are the secret weapon for sustainable European cities. Although these sites often have contamination problems and require intervention to bring them back into beneficial use, they are also often in the right place to deliver profitable places for people. This is in line with the perspective of EU flagship initiative “A resource efficient Europe”, where land is seen as a valuable and multi-purpose resource. In this session, perspectives of land management achieving this goal are presented. In addition, the EU Urban Agenda will have an important role in achieving the target of Resource efficient cities. Therefore in this session we will discuss about what research and developments are needed to enable cities contributing to a resource efficient Europe, which can be used as input for the Urban Agenda.

Program:

Presentation: Zero Brownfield Perspective: explain framework, how it works and remaining questions (15min)

Presentation: EU Urban Agenda (15min)

Discussion: Towards Urban Land Management 2065: what research and development is needed to enable that cities contribute positively to a resource efficient Europe (45 min) Conclusions and further actions (15 min)

Meeting room 19 SpS 1B.2Sa Workshop on groundwater contamination from pesticide point sources Part I Organizers: Ida Holm Olesen (Region of Southern Denmark, DK), Nina Tuxen (Orbicon A/S, DK), Poul L. Bjerg (Technical Universty of Denmark, DK) Moderator: Poul L. Bjerg (Technical Universty of Denmark, DK)

Pesticides are among the most widespread contaminants in the European groundwater. Recent findings in Denmark indicate that between 20 and 45% of the pesticide findings in the groundwater can be attributed to point sources. Danish researchers, authorities and consultants have developed innovative tools for data analysis, catchment scale risk assessment and remediation. We believe we are on the right path, but we are very well aware that we have not yet found the recipe for efficient management of pesticide-point sources. Judged by the limited amount of literature on pesticide point sources available, it seems that other European countries are in a similar situation. Therefore, the aim of this workshop is knowledge exchange and mutual inspiration on the topic of pesticide point sources. Ideally, the session will facilitate forming of new European partnerships on further research and development among authorities, consultants and researchers. All participants are invited to contribute to knowledge exchange by brief presentations and participation in discussions on key issues.

Auditorium 10 SpS 1B.1S Implementation of the EU Water Framework Directive – how to manage contaminated sites threatening surface waters Organizers: Sandra Roost (Orbicon A/S, DK), Jens Aabling (Danish Environmental Protection Agency, DK), Nina Tuxen (Orbicon A/S, DK), Trine Korsgaard (Region of Southern Denmark, DK), Helle Overgaard (The Capital Region of Denmark, DK) Moderator: John Flyvbjerg

The implementation of the EU Water Framework Directive requires an integrating and holistic approach to legislation for water bodies with a goal of obtaining good environmental status for all receiving waters. While the risk from contaminated sites to groundwater has received a great deal of attention in the past, the risk from contaminated sites to surface waters (streams, lakes and coastal waters) has not yet been well examined. In Denmark alone there are more than 30,000 contaminated sites registered – many of them located close to surface waters. However, the hypothesis is that only a minor part of these sites actually pose a real risk towards surface waters. Thus a robust method is needed to identify the few relevant sites which still comply with the precautionary principle. Together with leading experts from universities, consulting companies and regional authorities, the Danish EPA developed a screening tool to identify contaminated sites that threaten

surface waters. The screening system integrates national data of the contaminated sites: location, distance to surface waters, contamination activity, contaminant area and mass flux and calculates the mixing in surface waters.

The legislators (Danish Environmental Protection Agency), the regulators (the Regional governments) and the performing part (consultants and contractors) in Danish soil and groundwater issues have a very unique working environment based on a strong scientific knowledge on all levels and very competent performers in the field. In the last three decades, Denmark has built a unique model for dealing with soil and groundwater contamination. The aim of the session is to inspire others by sharing the Danish approach of how to handle contaminated sites on all levels; our good and bad experiences on this topic, and with this, hopefully creating international working relations where we all share, learn and take home the best from each other´s practices.

Meeting Room 20 SpS 1C.5S Contaminated site remediation – practical decision making Organizer: John Hunt (Engineering Co, AU)

This session focuses on how to make decisions regarding the remedial strategy for contaminated sites and associated information requirements above and beyond the assessment data required to implement a management or active remediation strategy. Australia has been developing national guidance on the remediation of contaminated sites;

this involves consideration of how other countries approach the problem, and how concepts such as risk-based land management and sustainable remediation should be included. The concepts presented in this session should be of interest to many countries, particularly those that are grappling with how to achieve the greatest return from the investment in remediation of contaminated sites. The session includes speakers who are highly experienced in remediating contaminated sites and have a good understanding of international approaches being applied, and the thinking that underlies good decision making related to contaminated sites.

SpS 1A.7S US EPA Session 1: Best Practices for Site Characterization

Organizers: Carlos S. Pachon and Stephen A. Dyment (United States Environmental Protection Agency)

A clear theme arising from EPA’s optimization studies is the need for more accurate characterization of site conditions to ensure remedy efficiency and success. The goal of the session is to share our lessons learned, discuss opportunities and challenges with professionals in the audience and to gain insights from the experiences of others.

This session will present an overview of efforts to “optimize” site characterization, including leveraging the use of existing site data, the importance and application of a “life-cycle” Conceptual Site Model (CSM), the use of high resolution site characterization techniques to improve the design and implementation of groundwater remedies, the use of incremental sampling methodologies to improve the representativeness of characterization of soils, and the use of newer visualization tools to better plan and monitor site cleanup.

Auditorium 10 SpS 1B.5S Vapor intrusion - state of the art

Organizers: Tage V. Bote (COWI, DK), Per Loll (DMR, DK), Mads Georg Møller (Orbicon A/S, DK), Bjarke N. Hoffmark (COWI, DK)

Moderators: Per Loll (DMR, DK), Tage Vikjær Bote (COWI, DK), Bjarke N. Hoffmark (COWI, DK)

Since the mid-1990s, vapor intrusion has been a major issue in Denmark, and today vapor intrusion is a significant part of handle contaminated sites. Over the last two decades, investigation techniques and approaches have been developed to locate and determine the amount of vapor intrusion. These initiatives have provided us with highly specialized knowledge about the mechanisms controlling the vapor intrusion. Remediation techniques have been developed and refined and now offer greater security against vapor intrusion.

The aim of the session is to share our knowledge about vapor intrusion including investigation and remediation techniques. The acknowledgement of vapor intrusion varies from country to country due to political and cultural differences. However, differences in the ways vapor intrusion is handled are also due to differences in building constructions and climate – factors that are of great importance to processes that control vapor intrusion. Another aim of the session is therefore to discuss this diversity in order to give both participants and speakers a better understanding of the similarities and differences and the extent to which we can apply knowledge and methods from one country/region to another.

Meeting Room 20 SpS 1C.4S Sustainable Remediation – avoiding greenwash by striving to demonstrate better results Organizers: Claudio Albano (CH2MHILL & SuRF Italy & International SuRF Network) Laurent Bakker (TAUW & NICOLE SRWG) Moderators: Jonathan Smith (Shell Global Solutions & SuRF UK), Dominique Darmendrail (COMMON FORUM on Contaminated Land in Europe)

In London 2008 Soil and Groundwater Technology Association (SAGTA) in association with Network for Industrially Contaminated Land in Europe (NICOLE) held the first European conference raising the issue of sustainability in land remediation. Concurrently Sustainable Remediation Forum-UK (SuRF-UK) along with a NICOLE Working Group on Sustainable Remediation were established providing new forums to exchange information and innovating concepts. Now there are Sustainable Remediation Fora all around the world and international knowledge exchange is well established. Over the years these networks have strived to present case studies proving the advantages of sustainable remediation but have noticed many case studies of ‘greenwash’ instead.

Decision making should be kept simple when possible and more complex if appropriate. We have noticed a trend that all kinds of complex tools and methodologies are now being used although the reasoning to choose the most suitable sustainable solution is often obvious, primarily when proper stakeholder engagement is in place. The session updates on activities and learnings, providing space for discussion and networking.

25 Years ago the first generation of human exposure models was published. Today, human exposure models are widely available and worldwide used on a large scale, often without much review or criticism. In many contaminated soil and groundwater appraisals, however, human exposure models contribute significantly to good risk assessment and risk management practices. More than that, human exposure models often are considered as the core tool in risk assessment and risk management of contaminated soil and groundwater. Therefore, the question is warranted after 25 years if human exposure models are ‘finished’ or if serious knowledge gaps remain. Moreover, an interesting question is how human exposure models are used in practical applications.

Auditorium 11 SpS 1C.23S Nanoremediation 1- all you wanted to know (a practical guide to nanoremediation) – Organizers: Paul Bardos (r3 environmental technology ltd, GB), Juergen Braun (University of Stuttgart, DE), Miroslav Černík (Technical University of Liberec, CZ), Dan Elliott (Geosyntec Consultants, US), Elsa Limasset (BRGM, FR), Hans-Peter Koschitzky (University of Stuttgart, DE) Moderator: Paul Bardos (r3 environmental technology ltd, UK)

Part I of the Nanoremediation session focuses on providing a practical grounding in nanoremediation theory and practice with particular reference to applied examples in the field. Part II of the session focuses on providing business and strategic intelligence for delegates with interests in utilizing or developing nanoremediation activities within their organisations or at client sites. (Part II is scheduled on 11 June 2014 at 11:00 hrs in Auditorium 11.)

Nanotechnologies could offer a step-change in remediation capabilities: treating persistent contaminants which have limited remediation alternatives. In 2007 in Europe it was forecast that the 2010 world market for environmental nanotechnologies would be around $6 billion (JRC Ispra 2007). In fact, adoption of nanoremediation has been much slower. However, the recent emergence of nanoremediation as a commercially-deployed remediation technology in several EU countries indicates that it is timely to reconsider its potential applications and the consequent implications for their business activities. Since early 2014, the EU FP7 NanoRem project (www.nanorem.eu) has been carrying out an intensive development and optimisation programme for different nanoparticles (NPs), along with analysis and testing methods, investigations of fate and transport of the NPs and their environmental impact. NanoRem is a €14 million international collaborative project with 28 Partners from 12 EU countries, and linkages to the USA and Asia. It is a major initiative, which will support the effective deployment of nanoremediation technologies in Europe.

Questions and answers

Meeting Room 20 SpS 1C.6S Sustainability in contaminated site management – case Finland Organizers: Jaana Sorvari (Aalto University, FI), Seppo Nikunen (Pöyry Finland Oy, FI), Jussi Reinikainen, Outi Pyy (Finnish Environment Institute, FI), Anna-Maija Pajukallio (Ministry of the Environment, FI) Moderator: Jaana Sorvari (Aalto University, FI)

In Finland, the number of potentially contaminated sites, recorded in the national database known as MATTI, currently totals some 25,000. Most of these sites have not yet been investigated but it has been estimated that 11,000 sites need to be remediated in the future. The estimated cost of these activities is 4 billion euros. At the same time, state funding is scarce and covers roughly only 5-10% of the total costs. Hence, in most cases the costs of remediation need to be paid by private problem owners. This is a challenge from the viewpoint of the realization of sustainable contaminated site management (CSM) since no incentives actually exist to consider all components of sustainability in decision making. The session aims to present how Finland has tried to solve the problem of the implementation of sustainability principle in CSM, when both the economic and human resources are scarce, market is limited and the practical issues such as logistics and lack of guidelines create barriers to it.

Meeting Room 19 SpS 4.2S Artificial recharge of coastal aquifers Organizers: Koen Zuurbier (KWR Watercycle Research Institute, NL), Gualbert H.P. Oude Essink (Deltares / Utrecht University, NL), Niels Hartog (KWR Watercycle Research Institute / Utrecht University, NL) Moderator: Niels Hartog (KWR Watercycle Research Institute / Utrecht University, NL)

Local, small-scale managed aquifer recharge (MAR) may provide site-tailored freshwater management solutions in coastal areas that are increasingly under pressure through both population growth and climate change. These solutions may provide flexible solutions worldwide for varying conditions, such as more extreme water events (drought and pluvial flooding). The local MAR-solutions demonstrate robust solutions for freshwater management by exploiting temporal natural freshwater sources (rainwater, surface water, drainage water, waste water) for abstraction upon storage in times of demand for irrigation, industrial, and drinking water purposes. Through the analysis of various field cases it can be demonstrated how to deal with different geological settings, application in brackish/saline groundwater, water quality changes and pre-treatment preceding injection.

Auditorium 10 SpS 1B.4S TRIAD investigations of soil and groundwater contamination – experiences and future possibilities, pros and cons Organizers: Dorte Harrekilde (Ramboll, DK), Anna Toft, Peter Lysholm Tüchsen (The Capital Region of Denmark, DK) Moderator: Dorte Harrekilde (Ramboll, DK)

The use of the TRIAD approach to investigate contaminated sites has increased over the past years in Europe. The TRIAD approach aims at achieving a greater sample density and real- time analyses with systematic planning and dynamic work strategies. One of the overall objectives is to minimize the number of field campaigns and to reduce nuisances for the property owner by assuring more rapid investigations.


28

During this session experiences with the TRIAD approach will be presented and discussed. Further on the program: pros and cons for using TRIAD, challenges, contaminants that are most suitable for TRIAD investigations, constraints in suitability depending on the type of investigation to be carried out i.e. when is the TRIAD approach suitable for delineating a groundwater plume, for carrying out initial soil investigations or for more complex investigations, quality of TRIAD investigations compared to traditional investigations, use of elements of the TRIAD approach in traditional investigations.

Meeting Room 17 SpS 1C.24S Nanoremediation part 2 - your future business opportunities (strategic and market intelligence) – Organizers: Paul Bardos (r3 environmental technology ltd, GB), Stephan Bartke (Helmholtz Centre for Environmental Research, DE), Nicola Harries (CL:AIRE, GB), Hans-Peter Koschitzky (University of Stuttgart, DE) Moderator: Nicola Harries (CL:AIRE, GB)

Part II of the Nanoremediation session focuses on providing business and strategic intelligence for delegates with interests in utilizing or developing nanoremediation activities within their organisations or at client sites. (Part I of the session is scheduled on 11 June, from 9:00-10.30 hrs – Auditorium 11, and provides a practical grounding in nanoremediation theory and practice.)

Nanotechnologies could offer a step-change in remediation capabilities: treating persistent contaminants which have limited remediation alternatives. In 2007 in Europe it was forecast that the 2010 world market for environmental nanotechnologies would be around $6 billion (JRC Ispra 2007). In fact, adoption of nanoremediation has been much slower. However, the recent emergence of nanoremediation as a commercially-deployed remediation technology in several EU countries indicates that it is timely to reconsider its potential applications and the consequent implications for their business activities. Since early 2014, the EU FP7 NanoRem project (www.nanorem.eu) has been carrying out an intensive development and optimisation programme for different nanoparticles (NPs), along with analysis and testing methods, investigations of fate and transport of the NPs and their environmental impact. NanoRem is a €14 million international collaborative project with 28 Partners from 12 EU countries, and linkages to the USA and Asia. It is a major initiative, which will support the effective deployment of nanoremediation technologies in Europe.

Jaap Tuinstra (Dutch Soil Protection Technical Committee TCB, NL), Timo Heimovaara (TU Delft, NL; to be confirmed) Moderator: Justine Oomes (Ministry of Infrastructure and Environment, NL)

In order to realize our ambition on climate, energy and a comfortable living environment the subsurface will be used more intensively in the near future. Rapid innovations and economic circumstances give the opportunity to increase our use of the subsurface. This increase in multiple uses creates a pressure on the subsurface which needs to be managed. Unforeseen events occur in every-day projects and can have negative social, cost or environmental impacts and limit other uses in the subsurface. This was the reason for a preliminary Dutch study and recent publication „Unexpected events in the subsurface“ (TCB, Witteveen+Bos and Deltares). This study implies a broad analysis of causes and consequences combined with lessons learned from illustrated cases. It resulted in insights with respect to the negative impact of unforeseen events and the factors that play an important role in occurrence and prevention. Looking at traditional tendering (knowledge sharing, risk evaluation and liability) and High Reliable Organizations helps us to find possible solutions to manage unforeseen events. The preliminary study has shown that knowledge availability and sharing, risk sharing during tendering, transparency and attitude toward unforeseen events and good governance play an important role in enhancing our grip on unforeseen events. The session organizers wish to enrich the Dutch experiences and lessons learned with experiences of professionals from other countries represented on AquaConsoil.

Meeting Room 18 SpS 2.1S The carbon dilemma: biomass for the biobased economy or for soil fertility? Organizers: Sandra Boekhold (Soil Protection Technical Committee, NL), Margot de Cleen (Dutch Ministry of Infrastructure and the Environment, NL) Moderator: Margot de Cleen (Dutch Ministry of Infrastructure and the Environment, NL)

Harvest biomass for a biobased economy or leave it on the land for soil fertility? This is the central topic of this session. Soil organic matter is an important asset of soils. It is relevant for soil fertility and food security, water holding capacity and carbon storage. Loss of soil organic matter is considered to be a threat in the EU soil strategy. Additionally, society aims at sustainable development goals and greening the economy. Soil organic matter is a key parameter for these aspirations. How can soil quality be maintained in a biobased economy that increasingly demands biomass. Can we estimate an optimal soil organic content? What percentage of the harvest residues should be left on the land? Does it matter which crop to grow? What is the environmental risk of potentially contaminated organic residues?
