NameIng. J.A. (Ton) van Leerdam, BScSenior Researcher Chemical Water QualityTeam leader Laboratory for material researchton.van.leerdam@kwrwater.nl(+31) 30 606 96 24ProfileAs senior researcher, he focuses on the research, development and implementation ofnew analytical techniques and methods for safeguarding chemical water quality.Ton studied analytical chemistry focussed on mass spectrometry as identificationtechnique. He had more than 25 years experience in the field of water research, focussedon the use of state-of-the-art analytical techniques.Ton is also team leader of the Laboratory for Material Research and Organic analysis,managing a team of 10 laboratory experts and project manager.Keywords in specialisation are: analytical techniques, method development, chemicalwater quality, emerging compounds, identification of unknown compounds.Education• Technical University Rotterdam, analytical chemistry.• Research: ” The use of methane and ammonia in chemical ionization massspectrometry for the identification of unknown micro contaminants in water “Experience record• 1986-present: Senior Researcher Chemical Water Quality, KWR WatercycleResearch Institute, Nieuwegein.• 2010-present: team leader of the Laboratory for Material Research and chemicalanalysis, KWR Watercycle Research Institute, Nieuwegein• 2012-present: project managerMain responsibilities:• Research and development of new analytical techniques and methods for screeningand identification of potential chemical threats to water quality• Implementation of newly developed analytical techniques and methods for drinkingwater laboratories• Managing a team of 10 laboratory experts.Projects (recently and relevant)• Identification of unknown chemical compounds in different water types by thecombination of LC-UV, LC-MS/MS and NMR• Screening and identification of unknown polar compounds in surface water,groundwater and drinking water by LC-DAD-Orbitrap MS (accurate massmeasurements)

• Method development for the detection of specific group of emerging compounds (e.g.drugs of abuse, pharmaceutical compounds, degradation products and industrialcompounds).
