Goranina (2014) ( Open Chemistry ) About the study Location of the study: Lithuania Problem statement: To track the groundwater using Sodium Fluorescein. Procedure adopted: Sodium fluorescein is used as a tracer for 2 systems to determine the groundwater flow direction. Methodology Sodium fluorescein (C 20 H 10 Na 2 O 5 ) is used . • The monitoring well network consists of two subsystems. • System I in the north-western part of the site consists of 8 wells: 7 observation (S1-1, S1-2, S1-3, S1-4, S1-5, S1-6, S1-7), and one injection. • This well set examines the semi-confined aquifer 10 to 19 m deep. • Sandy clay occurs at 4.7–6.7 m. • The aquifer of medium-grained sand is below. Borehole S1-7 is installed 4 m deep in an aquifer of technogen
