NOMIC proposes a new methodology to characterize natural organic matter (NOM) and its behavior during treatment processes. NOM is ubiquitous in aquatic environment. While nontoxic, NOM largely outweighs the reactivity of micropollutants and consumes the majority of the oxidants used during drinking water treatment. The transformation of NOM produces potentially toxic compounds in treated waters. Most of those by-products are still unknown. Innovative tools will be applied to characterize halogen incorporation and nitrogenous reactive species in real waters. Key precursors and transformation products will be identified and a predictive modelling will be developed. An alternative methodology to evaluate the toxicity towards intestinal cells will be developed. Finally, an on-line monitoring campaign in which a smart sampling tool will be developed will be performed on a key water resource of Lille metropolis.
