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.
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.
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.

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.
Four consultants of different nationalities will be invited to give a description of a contaminated site, and asked to prepare a presentation of how they would tackle this case in their country. The session aims to show both differences and similarities in our approaches across national borders – and to inspire us to collaborate with and learn from our European neighbors. The case descriptions will contain information about required regulatory approvals/permits, the necessary extent of investigations (and remediation) to understand and risk assess the site, methods for investigation (and remediation) of the site and stakeholders.
Program:
• Introduction (10 min)
• Danish case solution (15 min)
• UK case solution (15 min)
• FR/IT/ES case solution (15 min)
• Eastern European/US case solution (15 min)
• Panel/plenum discussion (20 min)
Polling equipment will be available to the audience during this session. Polling questions will be asked during the individual presentations and especially during the panel discussion. Results will appear on-screen immediately and be an integral part of the discussions.
This session will illustrate how the soil-water-sediment system is interconnected, influenced by land use and land management (the connectivity concept) and thus impacts solutions of
great societal challenges such as climate change adaptation, food and drinking water security, resource efficiency, energy transition and the circular economy. Information about the H2020- project INSPIRATION will be shared; this project is a coordination and support action aiming at developing a Strategic Research Agenda (SRA) for Europe on Integrated Spatial Planning, land use and soil management. Information will be exchanged on the main societal
challenges in different regions of Europe related to the sustainable use and management of land’s soil-water-sediment system. An outline will be given on shared national and European research priorities and potential funders and stakeholders (willing to invest).
An aim is also to contribute to (or enable) the formation or strengthening of transnational networks on similar themes and to anticipate on possible cooperation within consortia for Horizon 2020.
Program:
• Connectivity of the complex soil-water-sediment system in relation to land use and land management
Key note presentation – speaker to be confirmed
• Introduction on INSPIRATION
Detlef Grimski, project coordinator (Federal Environmental Agency, DE)
• Discussion in groups on societal issues related to land use, land management and the use of the soil-water-sediment system that are high on national and regional (research) agendas
• Plenary reporting back
• Discussion in groups on priority research subjects and potential stakeholders and funders for these main themes
• Plenary reporting back
• Closing remarks
The availability of fresh water is under pressure in coastal and (semi-)arid regions due to climate change leading to extended drought periods, sea level rise, and due to increased water demands by industry, agriculture and domestic sectors. This session will debate new regional solutions for securing water availability and the need of cross sectorial cooperation between government, industry, agriculture, and scientists.
Program:
• The global and local perspective and the role of green infrastructure and subsurface in fresh water supply in water scarce regions
Huub Rijnaarts (Wageningen University, NL)
• Global change and the role of government: how to obtain more involvement of industry and research in solving local water availability and the sustainable use subsurface Ruud Cino (Ministry of Infrastructure and Environment, NL)
• Cooperation in water management between urban, rural and industrial stakeholders: from regional water management perspective to local implementation Representative of the Barcelona region, Spain
• The ambition of industry in sustainable use of resources including water and subsurface; tailoring industrial operations and regional settings towards self-sufficient water management

• Considering the influence of climatic uncertainty in designing measures to protect and restore critical water resources
Scott Warner (ENVIRON International Corporation, US), Devon Rowe (ENVIRON, US); Gretchen Greene (ENVIRON International Corporation, US)
The evolution of the Superfund program has progressed from an early focus on pump & treat systems and long term monitoring networks, to a more comprehensive and holistic site evaluation conducted at any phase throughout the cleanup process. The ultimate goal being design, construction, and operation of the most efficient, effective, and protective remedies EPA and stakeholders can provide.
This session will explore the evolution of EPAs optimization programs and highlight how thinking has evolved from presumptive application of large scale aggressive remediation technologies to a focus on high resolution site characterization and conceptual site model development in support of adaptive management for application of multiple targeted treatment technologies. The session will then open for a discussion on key trends in cleanup, research and development efforts, and needs faced by the cleanup community as a whole.
