The Minnesota Groundwater Tracing Database (MGTD) contains information from nearly 400 groundwater traces in Minnesota. The groundwater traces were primarily conducted using fluorescent dyes. This information includes tracer input locations, inferred groundwater flow vectors, surface and subsurface springshed delineations, a comprehensive list ...

Type of Tracers. 1.Natural Tracers. it involves the use of naturally occurring components of a water sample to determine information about the source and age of the sample. Used in case of age-dating. Environmental isotopes are now used to trace not only groundwater provenance, but also recharge processes, subsurface processes, geochemical ...
What Groundwater Tracers to use and why?
https://public.ornl.gov/orifc/FRCWorkshop2004/Breakout_WorkingGroup_Geochem/Tracers.pdf
What Groundwater Tracers to use and why? A chemical tracer is a substance used to track the progress or history of a natural process. Some tracers occur naturally and others are introduced experimentally. A tracer can also acts as a surrogate for a solute or organism of interest. As hydro/geo/micro subsurface folks, we must ask ourselves what ...
Ground-Water Tracers - EPA

History of Ground-Water Tracing One of the first tracing experiments was performed almost 2,000 years ago when Philip, the tetrarch of Trachonitis, threw chaff into a crater lake. He reported that the chaff appeared downgradient in one of the springs at the headwaters of the Jordan River. Although Josephus reported that the experiment was a ...

Qualitative groundwater tracing methods are widely accepted by the karst hydrology commu-nity. Some researchers have criticized qualitative groundwater tracing (Field, 2003), whereas other practitioners defend it vigorously (Worthington and Smart, 2003). In my experience, groundwater dye tracing is highly efficient and reliable. Qualita-
Fluorescent Dye Tracing Basics
https://dyetracing.com/dye-tracing
What is dye tracing? Fluorescent dye tracing is used to study the movement of groundwater. Dye trace investigations are designed to solve problems involving the origin, destination, routing, and velocity of groundwater flow. This is typically the first step for obtaining information for aquifer monitoring, pollution prevention, or water ...
Hydrological Tracers - Environmental Sampling
https://serc.carleton.edu/microbelife/research_methods/environ_sampling/hydrotrace.html
These methods can also hold true for groundwater tracers, but it should be noted that movement through ground water can also introduce salts to the samples, so knowing the bedrock geology of the study site can be helpful. ... Chloride represents a useful tracer, since it is relatively inert and not used by biota in a great degree. Nitrate would ...
