A workshop on natural organic matter and trihalomethanes will be hosted by the Natural Organic Matter Project (Trinity College Dublin and National University of Ireland, Galway) on the 16th of June in Hotel Meyrick, Galway City followed by a technical tour of Luimnagh Water Treatment Plant on the 17th of June.

Overview

Disinfection by-products (DBPs) are formed when natural water is treated to control microbial presence during the drinking water treatment process. DBPs can comprise halogenated and non-halogenated compounds depending on the nature of disinfectants used and the precursors present. Trihalomethanes (THMs) are the most prominent class of DBPs in treated water; however, more than 600 different DBPs have been acknowledged. THMs are formed when chlorine reacts with aromatic structures in humic substances. Ireland has the highest reported non-compliance for THM exceedances across the 27 EU Member States.

The objectives of the proposed workshop are to share experiences of international and national research from scientists in relation to natural organic matter (NOM) and DBPs; define the problems water managers are faced with in relation to NOM and DBPs; discuss priority research questions for further study; and establish an Irish NOM network.

Topics to be discussed include:

• National Trihalomethanes Project 2012
• Industry requirements from NOM research
• Private Group Water Schemes - NOM & THMs
• The impact of changing water quality on treatment of NOM laden water sources
• Reservoir Aeration to Remove THMs
• Using Zeta potential measurements for coagulation control
• Industrial Monitoring of Dissolved Organic Matter with the Aqualog: DBP Formation, Membrane Fouling and Algae contamination
• Role of freshwater NOM in the marine environment
• Connecting science, policy, managers and local communities for the integrated management of Ireland’s water resources
• Dynamics of NOM in natural waters
• Trends in DOC in boreal and temperate water bodies - from headwaters to large rivers
• Acidification and its role in NOM
• NOM contribution from organic soils
• NOM modelling in a west of Ireland catchment
• NOM in the Northern Irish aquatic environment: Sources, fluxes, impacts and fate
• Assessment of NOM in Irish drinking water

Who should attend?

Water managers, scientists, engineers, industry partners, environmental managers, heritage officers, planning officers, policymakers, and public.
