Table 4 Compact summary of Catchment III

From: Natural attenuation along subsurface flow paths based on modeling and monitoring of a pesticide metabolite from three case studies

Crops and use history
Treated crops Strawberries
Application 1980–1990; application in late spring and summer, BBCH growth stages > 60
Observation
Leachate sampling Matrix water samplings (mixed of 5 m sections) from drilling material of a bore, November 2017
Position of monitoring wells Immediately next to the treated field (downstream side) Close to the raw water abstraction Raw water collection gallery
Distance of treated area to downstream monitoring wells [m]  ~ 5  ~ 150–300  ~ 200–320
Geology/Lithology
Leaching profile Luvisol of loess loam covering quaternary glacial deposits (mainly silt/marl and gravel); partly as conglomerates,
Aquifer Quaternary high terrace gravel from Riß Ice Age (Dietmanns-formation)
Basement Tertiary Upper Freshwater Molasse
Location Southern Germany, Upper Swabia
Topography Field is located on an elevation, which is looped by a stream; slope is 1.5°; agricultural land use
Aquifer properties
Groundwater level below treated field [m] 39.9–47.5
Thickness [m]  ~ 10
Slope of aquifer [m]/[m] 2/300
Hydraulic conductivity [m/d] 43–86
Dispersivity (longitudinal/vertical) [m]; [m] 30; 0.3
Used models
Leaching modeling PEARL and HYDRUS-1D
