Groundwater age and travel time distributions have many applications – below you can find a link to a research paper where you can read about investigations of a pesticide polluted drinking water well and the history and fate of the two pesticides found in the well. The work is closely related to especially the work of task 6.4 in the HOVER project, which investigates groundwater age and travel time distributions in water supply wells with long screens and the application of these in groundwater management and protection as well as task 5.1: “Characterizing agrochemical travel time in the unsaturated and saturated zones” and 5.3: “Modelling nitrate and pesticide transport through unsaturated and saturated zones to groundwater receptors” of HOVER WP5.
