New Coordinated Research Project Launched

The IAEA launches a new Coordinated Research Project (CRP) entitled "Isotopes to Study Nitrogen Pollution and Eutrophication of Rivers and Lakes" (F32007).

Water quality in thousands of lakes and rivers around the globe is deteriorating due to rising nutrient levels and other chemical pollutants mainly of anthropogenic origin (e.g., agriculture, sewage, industrial discharges, and urban areas) causing changes in their ecological structure and function. This CRP will focus on exploring the use of nitrogen isotopes in N-nutrient dynamics in selected freshwater systems (lakes and rivers) facing eutrophication, nitrogen pollution, and cycling. This CRP aims to improve the suite of isotopic markers combined with other chemical / biological substances to better define the possible sources and re-cycling of nitrogen pollution in surface water bodies.

The CRP also aims to deepen the knowledge on the temporal (diel, seasonal) and in-depth variation of nitrogen isotope data, combined with additional substances, as deeper water bodies may sometimes prevent a complete understanding of nitrogen isotope dynamics from surface water collections. Moreover, improving conventional and exploring new methodologies on nitrogen species isotopic characteristics is expected to facilitate access to a more routine and low-cost use of nitrogen and oxygen isotope data of nitrogen species. Overall, the CRP will aim at improving expertise and collaboration among participating Member States in the use of environmental isotopes to better assess nitrogen pollution and eutrophication of lakes and rivers for optimal water resources management and remediation strategies.

CRP PROPOSAL DEADLINE: 2 October 2015. For further information or questions please contact Mr I. Matiatos

The IAEA and Japan review groundwater issues in the vicinity of Fukushima Daiichi Nuclear Power Plant

A technical meeting with experts from Japan and the IAEA reviewed the impact of the accident in the wake of March 2011 earthquake and tsunami on surface and groundwater systems in the vicinity of TEPCO's Fukushima Daiichi Nuclear Power Plant. Approximately 400 m3 of groundwater is estimated to be flowing into the main buildings each day. To prevent contaminated water outflow to the sea, TEPCO plans to install impermeable walls with a soil freezing method under the ground. In the off-site areas, people living in the vicinity of Fukushima are concerned about the safety of groundwater, well water and other freshwater. The national and local governments are conducting extensive monitoring of different water sources.

The objective of the meeting held at the IAEA Headquarters, Vienna, on 8 – 10 September 2014, was to discuss the nature of groundwater and surface water contamination at the Fukushima NPP and vicinity, and to share the experiences, particularly in terms of countermeasures and communication with stakeholders, at other areas, such as Chernobyl, Ukraine, Sellafield, UK, and Hanford and Brookhaven, USA. The meeting was in line with the Action Plan on Nuclear Safety, unanimously endorsed by the IAEA's Member States in September 2011, which defines a programme of work to strengthen the global nuclear safety framework.

Follow-up actions are being planned and would include an expert mission focusing on issues related to the calibration and validation of the groundwater model used for designing and monitoring countermeasures for controlling the flow of contaminated groundwater. A summary report of the meeting is available here and presentations made by the participants are available here
