  3. 3. 3 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter EDITORIAL Dear SG members, while the organisation of the next ICWS2014 in Shanghai is smoothly taking place, I’d like to bring your attention on some statistics that I’ve received from the IWA HQ about the trends of our Specialist Group. As you can see in the following graph the SG membership is constantly in between 450-550 members (in 2014, not shown in the graph, we are back at 477), with a peak of 569 reached in 2013. This total number of members puts the SG in between the medium-size IWA groups and that’s already a great result obtained along the last 25 years of passionate participation in spreading the wetland technologies around the world and in going deeper and deeper in the related knowledge. Another great result is the worldwide regional distribution of the membership: in 2013, the majority of group members are from Western Europe, East Asia & the Pacific and Latin America & the Caribbean. It is worth notice that the big growth in Latin America & the Caribbean region and the decrease in Western Europe and The Middle East are noticeable. In the past 5 years, SG membership figures have been growing continuously in some regions such as China and South Asia. Taking these considerations in mind and wishing for further increasing trends, I invite you all to devote a few minutes for reading the new SG constitution. The changes made and
  4. 4. 4 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter approved by the Managing Committee are aimed to involve as much as possible all the members in decisions and in the SG activities. The “fast rotation” of the SG officers and coordinators, regulated by elections extended to the whole membership by electronic voting and the choice of the conference venues by a similar approach. These ideas are conceived for bringing new energies and ideas into the SG on a regular basis. As this is already happening, for instance with the recent application coordinated by Gabriela Dotro, for the creation of a new IWA Task Group aimed to the dissemination of the updated status of the wetland technologies by the involvement of our YWP members. The social media implemented in the last 2 years are also working fine, with a constant increasing number of followers of the Facebook page and members of the FB group and a quite good interaction taking place over there. It’s noticeable that the highest percentage of the page followers falls into the age range 25-34, showing a desirable interest to the topic by the young professionals and researchers. In the current world, the need of low technological profile approaches for solving numerous issues of the water and wastewater management worldwide is very high. Wetland technologies together to deep changes in the sanitation approaches, that in my vision must go towards fluxes segregation at the sources and be as much “resource recovery oriented” as possible in every single case, can surely have a primary role for a future sustainable approach in the overall water management. In economic terms this process could possibly involve important savings in respect to the current practices and provide as final result a better environment and reduced impacts of the urbanisation and use of land by the human race. We still need lot of research for being able to model performances and economical aspects related to treatment units used in diffuse approaches for i.e. greywater reuse, urban runoff management, CSOs, agro-industrial facilities, etc. So keep up going and contribute as you can and wish to this SG activities for making it grow up even more and involve all the other linked specialists in the water sector. Looking forward to meeting you all in Shanghai, Fabio Masi Chair of the SG
  5. 5. 5 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter RECENT AND UPCOMING SG ACTIVITIES by Günter Langergraber, Secretary of the SG This part of the newsletter shall inform you about SG activities since our last newsletter was published and future activities planned. 1) SG activities IWA yearbook 2014 On behalf of the Wetland Systems SG Fabio Masi prepared an article for the IWA yearbook 2014. Procedure for submitting proposals for ICWS conferences The MC of the SG decided that there should be a more strict procedure for presenting proposals for ICWS conferences. The general procedure for conference proposers shall be: 1. Call for proposals in the spring SG newsletter prior to the SG conference 2. Submission deadline for proposals about 6 weeks prior to the conference (template for proposals is available on the SG WaterWiki site and must be followed; this shall enable comparable proposals) - late proposals will not be considered anymore 3. SG officers reviews proposals and may ask for modifications 4. Proposals will be made available on the SG WaterWiki site at least 2 weeks before the SG meeting (conference) 5. Presentation discussion of proposals at SG meeting 6. Voting Members vote on the procedure to select the next conference venue. When discussing the procedure for submitting proposals for ICWS conferences the MC also started discussing the voting procedure. Some members expressed their wish to be able to vote also if they are not present at the SG meeting which are traditionally held during the SG conferences. In March 2014 we electronically asked the SG members regarding their preference: 1) Leave the procedure as it is, i.e. voting will be done by SG members present at the SG meeting after the presentations of the conference proposals; announcement of the winning proposal during the conference dinner or at the closing session of the conference. 2) Electronic voting after the SG meeting (i.e. vote will be open for all SG members for a period of 2-3 weeks after the SG meeting); announcement of the winning proposal in the SG newsletter released after the conference. 3) A mix between 1 and 2 (with personnel vote and electronic vote counting e.g. 50% each); SG members present at the SG meeting will vote personally, all SG members not present will receive an invitation to vote electronically after the conference; announcement of the winning proposal in the SG newsletter released after the conference.
  6. 6. 6 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter The result of this survey was as follows: 1) Leave the procedure as it is: 18 % 2) Electronic voting after the SG meeting: 48 %. 3) A mix between 1 and 2: 36 %. The results were clear. The majority wants to have a change of the voting procedure. Therefore the voting for the next SG conference will be from now on electronically after the SG meeting. In the case of more than 2 proposals a 2nd round of voting might be required (see SG constitution). Anyway, the SG lead aims finalize the conference voting procedure latest until the end of the year in which the SG conference takes place. SG constitution After the decision on the above-mentioned topics, the SG constitution was updated, and finally discussed and agreed with in the MC of the SG. The SG constitution becomes effective with the publication in this newsletter (see page 8). Election of new SG Regional Coordinators With the new SG constitution, we also decided that the Regional Coordinators, i.e. the Management Committee of SG, shall be elected from now on. The elections of the Regional Coordinators shall be in between the election of the SG leads, i.e. we have to organise the election of the new Regional Coordinators. All Regional Coordinators can be re-elected, i.e. the current Regional Coordinators need to apply to become Regional Coordinator again. The current SG officers (chair and secretary) are members of the MC and are therefore not eligible candidates for this election. When the SG officers are stepping back, they stay members of the MC to ensure a smooth hand-over to the new SG officers. For the next election of Regional Coordinators, they can be candidates again. Additionally, it was decided that the number of Regional Coordinators should be in line with the number of SG members in the regions. For the elections, the following Table lists the regions (based on regions defined by IWA), the SG members per region and the number of Regional Coordinators (RCs) we assign per region (in brackets the numbers of RCs we have up to now). The target was to have around 40 SG members per Regional Coordinator. Region SG members # RCs SG members / RC Africa 39 1 (2) 39 China 58 1 (1) 58 Asia (except China) 79 2 (1) 39 Oceania 37 1 (2) 37 Latin America 59 1 (1) 59 North America 44 1 (1) 44 The Middle East 11 1 (2) 11 Europe 199 5 (6) 40 Total 523 13 (16) 40 (average)
  7. 7. 7 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter 2) Proposal for new Task Group on "Mainstreaming the use of treatment wetlands" submitted Under the lead of Gabriela Dotro (Cranfield University, UK) we have prepared a proposal for a new IWA Task Group on "Mainstreaming the use of treatment wetlands". We defined 3 main tasks for the work of the TG: 1. Updating and enhancing of the IWA Scientific and Technical Report on Wetland Technology (ISBN 9781900222051). 2. Developing a new chapter on Wetland Technology to be included in the textbook “Biological wastewater treatment in warm climate regions” (ISBN 9781780402734). 3. Organising a workshop to increase collaboration with closely related IWA Wetland Systems SG. The proposed members of the TG core group are besides Gaby Dotro and myself, Jaime Nivala (UFZ Leipzig, Germany), Jaume Puigagut (UPC Barcelona, Spain) and Otto Stein (Montana State University, USA). To achieve its objectives, the TG core group aims to involve of a large number of active SG members. The proposal was submitted early May 2014, it is aimed to start the TG work in 2015. Once approved by IWA we aim to present the TG and its planned activities at the upcoming SG meeting in Shanghai. 3) Planned events and activities of the Wetlands SG The following events and activities are planned by the SG for 2014. • IWA World Water Congress, 21–26 September 2014, Lisbon, Portugal (http://www.iwa2014lisbon.org/): The Wetland Systems SG is co-organiser of the workshop "Advanced processes for the removal of micropollutants. Lessons learnt from full-scale plants and remaining issues". The workshop is mainly organised by the SG Assessment and Control of Hazardous Substances in Water and beside our SG also supported by the SGs on Sludge Management, Water Reuse and Design, Operation and Costs of Large Wastewater Treatment Plants. The workshop is now scheduled for Tuesday, 25 September 2014, at 13:30 with duration of 90 minutes. • 14th IWA Specialized Group Conference on “Wetland Systems for Water Pollution Control”, 12-16 October 2014, Shanghai, China (http://www.iwawetland2014.org/): The planning for our next SG conference is on track. Updates on the conference are reported later in this newsletter (from page 12 onwards). 4) Non-IWA events interesting for the wetland community: Finally, I would like to draw your attention to a non-IWA wetland event that might be interesting for you: • the 6th International Symposium on “Wetland Pollutant Dynamics and Control (WETPOL 2015)” will be organised by Gabriela Dotro from 14-19 June 2015 in York, UK (see http://www.wetpol.org/2015/).

  13. 13. On behalf of the Scientific Committee of the International Water Association (IWA) 14th International Conference on Wetland Systems for Water Pollution Control (ICWS), I am delighted to welcome participants to attend the 14th ICWS, Shanghai, China, 12-16 October 2014. It is twenty years since the 4th ICWS conference was held in Guangzhou and it is appropriate, following the considerable advances in the global use of wetland systems that our biennial conference should return to China. Historically, China has been both an innovator and a leader in the use of natural, sustainable and ecologically harmonious systems for water recycling and agricultural production and the relatively recent development of constructed wetland systems owes much to this legacy. On behalf of the Organising Committee of the Conference and the College of Environmental Science and Engineering, Tongji University, I warmly welcome wetland scientists, researchers, engineers and policy makers from all over the world in Shanghai. Shanghai is the most modern city in China that offers the visitors fascinating history, splendid architecture, modern public transportation, access to the most recent technological advances and the old-fashioned hospitality. Shanghai will offer our distinguished guests sincere friendliness and unique attractions. We are here to review the advances in understanding wetland processes, to exchange ideas and to discuss future challenges in wetlands for water pollution control. I look forward to meeting you all at the conference. The Organisers This conference is jointly organised by: Welcome and Invitation Prof Brian Shutes. PhD, M.A., M.Tech, CBiol, FSB. Emeritus Professor of Ecotechnology, Middlesex University, London. Vice-Chair, IWA Wetland Systems for Water Pollution Control Specialist Group, 1996-2008 Prof Qi Zhou. PhD, M.A. Professor of College of Environmental Science and Engineering, Tongji Unversity, Shanghai Chairman of Conference Organizing Committee 14th IWA International Conference Wetland Systems for Water Pollution Control Conference Language The official language of the conference will be English. There will be oral and poster presentations, with pre-printed abstracts of conference papers. There is increasing pressure to reduce the global demand for water and energy while providing low cost systems for water pollution treatment and recycling. Constructed wetlands fulfil these requirements and provide flexible and adaptable systems in a range of designed types and sizes for treating domestic, industrial, agricultural and mining wastewater and urban storm water. This 14th ICWS conference will provide an international platform for the presentation of recent research and developments and the exchange of ideas between environmental scientists and engineers, policy makers, industrialists, entrepreneurs and research students who share a common interest in the use of wetland systems for water pollution control. The conference will also provide an opportunity to experience the warm welcome and excellent hospitality that is given to visitors to China as well as the exciting environment of Shanghai, a global megacity. College of Environmental Science and Engineering at Tongji University School of Urban Construction and Environmental Engineering at Chongqing University. The conference will take place in Sino-French Center on the campus of Tongji University. Sino-French Center is a first-class conference center, which offers a 600-seat conference hall, and three medium to small scale meeting rooms. Conference Venue

  20. 20. 21 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter 1976: born in South Africa 1998: BSc Hons. in Geology (University of Portsmouth) 2003: MSc. in Water & Environmental Management (University of Staffordshire) 2005-6: research assistant (University of Staffordshire) Since 2006: Research & Development at ARM Group Ltd, England. Secretary of CWA (Constructed Wetland Association) INTERVIEWING CLODAGH MURPHY by Frank van Dien ECOFYT, The Netherlands For those who expected an interview with Dr. Peter Kuschk (as was announced in the last newsletter): due to his work commitments, we were not able to finish that interview in time. So I took control of the situation and picked another interviewee myself. That gave me the perfect possibility to do something about a trend we were in, a trend that amazed me, actually: so far, when the final question was asked "Who will be next?" it referred to a male person and usually an "eminence grise"... While we have so many interesting women in our midst! So: I picked someone from another gender, from another age. I do expect the interview with Dr. Kuschk to happen soon but for now; an Interview with Clodagh Murphy from ARM Ltd. Probably most people know you as one of the more light-hearted people in the Constructed Wetland world. Now, THAT is not really the best introduction ☺☺☺☺ but I and many others know you as a fun character with a Monty Python like sense of humour. Besides that, we know you from your pretty good presentations at the conferences - because you DO know how to be dead serious about Treatment Wetland Data. So maybe now it's time for even more people to find out a little more about you. For starters, I wonder: Where in your life did things definitely turn in the direction that resulted in your role in world of constructed wetlands? Oh wow, Frank, there are so many great women in the world of wetlands so I’m really honoured that you chose me as your next victim to be interviewed, I hope your readers are not too disappointed that I’m not Peter. Women have been involved in the study of CW since the beginning, Käthe Seidel was definitely the grandmother of wetlands and it's great to be part of a bigger wetland community, but we’re all scientists and engineers – gender doesn't really prevent us from being curious and wanting to look after our Pale Blue Dot. (http://www.carlsaganvideos.com/pale-blue-dot/pale-blue- dot) (Apologies for the occasional quote in this interview, but some people can sum up things far more eloquently than I ever could.) It's quite flattering to be compared to Monty Python, I definitely have a daft side - I’m a heady mix of science and comedy with a hint of nerdism, but there is a serious side to this Murphy ☺
  21. 21. 22 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter Where in my life did I turn in the direction of CW? I can tell you the exact moment. It was 2001, I’d spent the previous 2 years roaming around Australia and New Zealand and I didn’t really know what direction I wanted to head in career-wise. On returning to the UK, I had spent the summer with some inspirational people on a small island off the north-east coast of Essex. Coming from a collective background of environmental protection, monitoring, and recreation of Essex’s unique salt marshes, their advice was to get a Master's first, as this will help get into this field of work, so I studied part-time for my MSc in Water and Environmental Management and got introduced to CW via my dissertation which investigated the various prevention mechanisms in place to reduce the impact that agriculture had on the saltmarshes. I hadn’t intentionally set out to work with CW, I’d moved to Staffordshire and I was introduced to the work that ARM Ltd do through a friend. In 2006 I cheekily knocked on their door to see what job opportunities they had and I have been working there ever since. I don’t really have a job title as such, as I have quite a varied role including research and development, Environment and Quality Manager, PR production, and web-fairy. I’m also the secretary for the Constructed Wetland Association. What has kept you working on wetland systems? I love the fact that CW are multidisciplinary, there are so many processes going on inside a wetland that it keeps you on your toes and you are constantly learning. I need to keep learning, really don’t like the idea of stagnating! In the 8 years that I have been working with CW, the technology has evolved quite substantially due to better understanding of the removal processes and the implications of design on hydraulics and clogging. I’m incredibly lucky to be working for a company that pushes boundaries and embraces the changes, but more importantly, has its own treatment wetland playground for me to meddle with for scientific purposes. The friendly wetland community plays a massive part in keeping me working with wetlands, conferences invite and often encourage collaborations with groups of people who study, operate and design wetlands – this is a massive privilege and one not to be taken lightly. And it is something I really enjoy being a part of. Such collaborations have moved the technology on in terms of application and design, and has ensured that commercial organisations can design the most appropriate wetland configuration for full scale treatment systems for both municipal and industrial effluents. And can you tell me: what do you do, besides wetlands, what are your other interests? I’m really into photography at the moment, and music, I love going to live gigs and concerts. I have been known to divert my planned journey to the Perth conference via Sydney just to see my favourite band, I guess you could call that dedication … or madness! Other than that, I like to just be outside, enjoying what nature and the changing seasons have to offer, (cliché alert!) … you should always take time to smell the flowers and listen to the birds. I read this and can only think of: what band, Clodagh? What band made you cross a continent on the other side of the world? Coldplay! I saw them twice and got right to the front, when you are somewhat vertically challenged, you need to be at the front to prevent tall people blocking your view. The next question that comes up is: do you see 'our' wetlands (I don't really mean natural wetlands like these salt marshes you mentioned) as an ultimate solution for waste water teatment? And if so, in general or just occasional, like when no sewer system is available? And if not: IS there an ultimate solution? I don’t think they are an ‘ultimate solution’. We are a global village with incredibly diverse cultural practices, access to sanitation and most importantly, access to water; we don’t all
  22. 22. 23 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter have the luxury of flushing toilets. There are situations when CW are not the most appropriate solution and they should never be considered as a one solution fits all eventualities. I think more work needs to be done in situations where particular sanitation practices pose challenges for the implementation of CW treatment and how to make them an accessible solution for all budgets and material resources. What, in your opinion, is the most promising application area for wetland systems? The application of wetlands to treat municipal wastewaters is quite well studied. I feel the most promising application is for the treatment of industrial effluents. We are developing a greater understanding of these nutrient poor effluents, often contaminated with tricky compounds and through the aid of pilot scale systems, designing hybrid wetland systems to provide the optimal conditions for the required removal mechanism. Is there, to your knowledge, a Treatment Wetland that is an example for us all? Or just one that you can bring to our attention, for some specific reason? Wow, tough question. There are so many to choose from. I have to say that I’m immensely envious of the Langenreichenbach research wetlands managed by Jaime Nivala and her team at UFZ, offering direct comparison of wetland technologies. What a playground! We need more of those facilities across the globe. In terms of full scale systems, the wetland schemes operated by the Coal Authority in the UK are quite impressive, not just visually, but performance wise too. These wetlands are used to treat groundwater that collects in disused mines, in order to remove the iron and other metals. There are numerous disused mines all over the globe, including Australia and South Africa where this technology can be applied. What is the most needed area of further research and study for treatment wetlands? It's great when a wetland is performing well, however, wetlands that don’t perform well are far more interesting to research, but seem to be rarely reported on. There is a definite bias in published research which can be misleading when relying on that data to design wetlands. It’s a challenge to find out what the trigger was that tipped a perfectly functioning wetland into one that fails, it requires a bit of forensic investigation, but one that can only be properly investigated if there is sufficient data – this is quite often the sticking point. Full scale systems rarely have continuous monitoring, let alone data on flow, influent and effluent. Further research is needed in crash testing wetlands, identifying what causes systems to fail. I love the idea of testing wetlands to destruction but unfortunately, our clients are somewhat reluctant to allow us to break their newly installed systems, and quite rightly so. One of the best things about having your own wetland to play with, is you can test them to breaking point. I’m all in favour of breaking stuff in the name of science but we must remember to write it down, otherwise it's just messing about! Outside of crash testing wetlands, I’m quite interested in how aerated systems cope with synthetic estrogenic compounds, but the lab costs are a bit steep! What does this world need most at the moment? For people to consider the impact their actions have on society and the environment. To quote Terri Swearingen: “We are living on this planet as if we have another to go to.” What does the 'water cleanup world' need most at the moment? I have to agree with Joan on his answer to this question. We definitely need solutions that are accessible to all, not cost prohibitive and not dependent on complicated, energy hungry technology.
  23. 23. 24 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter So, you kind of combine MythBusters and Murphy's law in the Constructed wetland business? That is your true role? ☺☺☺☺ Yeah, Murphy’s Law, it really ought to be written into all Risk Assessments; whatever can go wrong, will go wrong! ☺ I see it as an unofficial spin off to the 2nd Law of Thermodynamics, the law that tells us any system tends towards disorder; it’s all about entropy…… set up an experiment, with everything in order, walk away to let it run, and it all descends into chaos! I believe the trick is to pre-empt the chaos and design it into your experiment, and if anyone’s managed to do this, please share your secret! How could we get to more cooperation in research? Would you have an answer to that? Collaboration and sharing resources is key. People have different strengths, skills and experiences and to coin a social media term: crowd-sourcing these skills is really essential. The Global Wetland Technology group is a fine example where they play on one another's strengths to deliver an appropriate solution. The gap between academia and the commercial application is ever closing. Workshops, like the one that took place at UFZ last year have really assisted this process by identifying what research businesses need to help design and install systems to meet the client's needs and ultimately improve our environment. And my last question is: who would you like to be interviewed next time? Someone I admire greatly, who has encouraged me every step of the way; my good friend Florent Chazarenc.
  24. 24. 25 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter VERTICAL FILTER ECOTECHNOLOGY SYSTEM (V-ECOTECH- FILTER): AN INNOVATIVE AND NOVEL ECOTECHNOLOGY FOR THE NATURE-LIKE REMEDIATION OF CONTAMINATED GROUNDWATER Khaja Zillur Rahman, Peter Mosig, Jaime Nivalla, Manfred van Afferden Helmholtz Centre for Environmental Research – UFZ, Centre for Environmental Biotechnology (UBZ), Permoserstr. 15, 04318 Leipzig, Germany. E-mail: roland.mueller@ufz.de, manfred.afferden@ufz.de, Tel.: +49-341-235 1848 Groundwater contaminated with MTBE (methyl tertiary-butyl ether) and BTEX (benzene, toluene, ethylbenzene, m-, o-, and p-xylene) represents unique remediation challenges at many refinery sites due to their complex physico-chemical properties. The active ex-situ remedial methods include air stripping and removal with granular activated carbon, vapor extraction, advanced chemical oxidation and multiphase high-vacuum extraction (Davis and Powers 2000; Deeb et al. 2003; Sutherland et al. 2004; Wilhelm et al. 2002). However, the cost associated with the construction, maintenance and operation of these conventional treatment technologies diminishes their feasibility. For the remediation of contaminated groundwater, an innovative and energy efficient vertical filter ecotechnology system (V-EcoTech-Filter) has been developed (van Afferden et al. 2011). It can be operated in an economic, reliable and robust mode over a long period of time. The two-stage vertical-flow soil filter system, a roughing filter and a polishing filter, developed by the UFZ performs very efficiently for the remediation of groundwater contaminated with MTBE and BTEX. The concentrations of MTBE and benzene in the final effluent meet the limits for re-infiltration given by the local water authority, allowing a re- infiltration of the water into the non-contaminated aquifer. This system has already been successfully implemented at a pilot-scale for the remediation of the Leuna mega site in Germany (Fig. 1). Fig.1: Pilot-scale plant at the Leuna mega site in Germany (photo: A. Künzelmann, UFZ) In the first treatment stage, the vertical filter is filled with coarse material which allows the possibility of applying higher hydraulic loads and prevents potential clogging due to precipitation of iron and manganese within the filter bed. Within the second stage the water passes through a fine-grained vertical filter with a longer hydraulic retention time for final polishing. The contaminated groundwater is injected from the top of each filter through a uniform distribution system of perforated PE pipes, which are laid horizontally under the cover layer (Fig. 2).
  25. 25. 26 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter Fig.2: Construction phase of the pilot-scale plant in Leuna, Germany (photos: P. Mosig, UFZ) This specially designed system with passive aeration facilitates rapid biodegradation of organic compounds, shows highly efficient treatment performance with very low levels of emissions of volatile compounds, no precipitations of ions (Ca or Mn) and operates smoothly in winter time even under outside temperatures as low as -20°C. Since the formation of lime (Ca-precipitation) may lead to a very high operation and maintenance cost, this specially designed system with minimal Ca-precipitation has a great advantage over the conventional groundwater treatment plants. This novel technology is the world’s first vertical filter system for MTBE and BTEX removal from groundwater. It can also be applied to other organic contaminants in process water of oil and gas industries. This technology can be licensed from the UFZ not only in Germany, but also worldwide. Recently, a total of eight full-scale treatment units have been constructed (Fig. 3) and are in operation at the Leuna site to treat all the groundwater of that contaminated aquifer with a volume of up to 600 m3 per day. The whole groundwater remediation plant at this site is financed by the German federal state of Saxony-Anhalt (Landesanstalt für Altlastenfreistellung, Magdeburg). The construction and operation are carried out by the company BAUER Umwelt GmbH, Germany, which has been assigned by MDVV, the state owned company responsible for the remediation of the Leuna site. Fig.3: Full-scale treatment plant in Leuna, Germany (photos: P. Mosig, UFZ) The official inauguration ceremony will take place on June 5, 2014 at Leuna treatment site, Germany.

Numerical simulation will be used as main tool to investigate the influence by using measured data from Polish full-scale systems for calibration and validation. The main outcome of the project should be a proposal for a larger scale research project in which these processes shall then be quantified and a model extension shall be developed. During the last meeting held from 18-20 March 2014 in Gdansk a training on the HYDRUS Wetland module (Langergraber and Šimůnek, 2012) was organised. Besides students from GUT also 3 colleagues from Lublin Life Science University participated in the training (see Figure 1). References: Langergraber, G., Šimůnek, J.

  31. 31. 32 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter NEW FROM IWA PUBLISHING Publications on Water Pollution Control Arsenic in Groundwater: Poisoning and Risk Assessment M. Manzurul Hassan, Peter J. Atkins ISBN: 9781780400204 November 2014 • 304 pages • Hardback IWA members price: £ 51.00 / US$ 91.80 / € 68.85 http://www.iwapublishing.com/template.cfm?name=isbn9781780400204&type=category The main focus of Arsenic in Groundwater: Poisoning and Risk Assessment is to explore the untold stories of groundwater arsenic in view of its poisonous nature for human health, social implications, exposure and risk assessment, worldwide concentrations with space-time dimension, micro level GIS application in spatial arsenic concentration, policy response and mitigation options, and water right and legal issues of safe drinking water. There are very few books on arsenic issues and almost all the books are mainly based on geology, geochemistry and health issues. There is a gap in spatial, social and legal issues of arsenic toxicity, and the lack of literature on GIS-based modeling for spatial risk of arsenic contamination is a serious methodological limitation. Therefore, this book is a departure for health geography with a social science and legal context. ----- Arsenic Contamination in the World An International Sourcebook Susan Murcott ISBN: 9781780400389 • October 2012 • 344 pages • Paperback IWA members price: £ 108.75 / US$ 195.75 / € 146.81 http://www.iwapublishing.com/template.cfm?name=isbn9781780400389&type=category Arsenic Contamination in the World: an International Sourcebook provides a global compendium of cited arsenic occurrences in the world as they affect public health. This book details arsenic contamination by source, region and arsenic-affected country. Arsenic is identified in 105 countries
  32. 32. 33 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter and territories, representing a larger database than any previous published work. Sources of arsenic contamination are categorized as Anthropogenic, Geogenic, Volcanogenic, Coal, Mining and Petroleum-related. National, regional and international maps locate the affected areas and populations. A synthesis of critical country information includes an estimate of the exposed population of 226 million people worldwide. This reference work is an indispensable tool for medical doctors, public health workers, scientists, water experts, governments, industries, non-profit organizations and communities in identifying site-specific arsenic contamination. An extensive bibliography of peer- reviewed literature gives the reader important arsenic contamination locations as the first step towards remediation. This Sourcebook is updatable via an on-line annex which provides up-to-date information on new arsenic occurrences and developments. We invite readers to participate in updating this database at: http://www.iwawaterwiki.org/xwiki/bin/view/Articles/ExecutiveSummaryofArsenicContaminationintheW orld By synthesizing the known occurrences of arsenic world-wide, this reference book offers an essential tool for understanding and addressing the global arsenic geological-public health interface. ----- Chemistry of Ozone in Water and Wastewater Treatment From Basic Principles to Applications Clemens von Sonntag and Urs von Gunten ISBN: 9781843393139 • September 2012 • 320 pages • Hardback IWA Members price: £ 74.25 / US$ 133.65 / € 100.24 Student price: £ 59.00 / US$ 106.20 / € 79.65 http://www.iwapublishing.com/template.cfm?name=isbn9781843393139&type=category Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is considerable concern about the formation of potentially harmful degradation products as well as oxidation products from the reaction with the matrix components. In recent years, a wealth of information on the products that are formed has accumulated, and substantial progress in understanding mechanistic details of ozone reactions in aqueous solution has been made. Based on the latter, this may allow us to predict the products of as yet not studied systems and assist in evaluating toxic potentials in case certain classes are known to show such effects. Keeping this in mind, Chemistry of Ozone in Water and Wastewater Treatment: From Basic Principles to Applications discusses mechanistic details of ozone reactions as much as they are known to date and applies them to the large body of studies on micropollutant degradation (such as pharmaceuticals and endocrine disruptors) that is already available. Extensively quoting the literature and updating the available compilation of ozone rate constants gives the reader a text at hand on which his research can be based. Moreover, those that are responsible for planning or operation of ozonation steps in drinking water and wastewater treatment plants will find salient information in a compact form that otherwise is quite disperse. -----

Stuetz, Anton P. van Harreveld ISBN: 9781780400600 December 2014 • 450 pages • Paperback IWA Members price: £ 78.75 / US$ 141.75 / € 106.31 http://www.iwapublishing.com/template.cfm?name=isbn9781780400600&type=category Complaints due to odour annoyance have become a major issue for wastewater treatment plant, waste management, landfill, intensive livestock and other industrial operators as the repeated release of unpleasant odorous emissions can constitute a nuisance to a local population. Traditionally, odour management has been maintained by the use of buffer distances between industry and receptors or by the installation of odour abatement systems that both collect and disperse the emission or treat the emission to acceptable level to limit receptor impact. With the expansion of suburbia and the associated encroachment, residents and industry are coming into closer proximity than in the past. This interaction is unpredictable, complex and difficult to address. Integrated odour impact management approaches involving improved measurement and understanding of odorous emissions, their impact on local receptors, treatment performance and integration in local community relations programs are needed to meet the potential impact due to population growth and increasing global urbanisation. ----- Soil and Water Contamination Second Edition Marcel van der Perk ISBN: 9781780404912 • Pre-order (Nov 2013) • 450 pages • Hardback IWA Members price: £ 37.50 / US$ 67.50 / € 50.63 http://www.iwapublishing.com/template.cfm?name=isbn9781780404912&type=category Soil and Water Contamination, 2nd Edition is the first textbook that treats soil and water pollution issues from a geographical/spatial perspective at point, local, regional, and catchment scales. It links up very well to recent environmental policy and legislation in the field of soil and water pollution, e.g. European Water Framework Directive. • Treats environmental pollution from 3 perspectives: pollutant, transport processes, and spatial and temporal variability of occurrence, teaching the student how to assess the spatial
  34. 34. 35 IWA Specialist Group on Wetland Systems for Water Pollution Control June 2014 Newsletter dispersal of pollutants in the environment, taking into account the properties of the pollutant, environmental medium, and transport processes. • Describes environmental behaviour of major contaminant groups, including nutrients, metals, radionuclides, and organic pollutants, which makes it a valuable reference for quick evaluation of the chemical behaviour of pollutants in the environment. ----- Water Reclamation Technologies for Safe Managed Aquifer Recharge Christian Kazner, Thomas Wintgens, Peter Dillon ISBN: 9781843393443 • April 2012 • 460 pages • Paperback IWA members price: £ 82.50 / US$ 148.50 / € 111.38 http://www.iwapublishing.com/template.cfm?name=isbn9781843393443&type=category Water Reclamation Technologies for Safe Managed Aquifer Recharge has been developed from the RECLAIM WATER project supported by the European Commission under Thematic Priority 'Global Change and Ecosystems' of the Sixth Framework Programme. Its strategic objective is to develop hazard mitigation technologies for water reclamation providing safe and cost effective routes for managed aquifer recharge. Different treatment applications in terms of behaviour of key microbial and chemical contaminants are assessed. Engineered as well as natural treatment trains are investigated to provide guidance for sustainable MAR schemes using alternative sources such as effluent and stormwater. The technologies considered are also well suited to the needs of developing countries, which have a growing need of supplementation of freshwater resources. A broad range of international full-scale case studies enables insights into long-term system behaviour, operational aspects, and fate of a comprehensive number of compounds and contaminants, especially organic micropollutants and bulk organics. -----
