Fig. 4From: How long do natural waters “remember” release incidents of Marcellus Shale waters: a first order approximation using reactive transport modelingEvolution at the release point for a Ba in water (mg/L), b Ba on surface (mol/g solid), c Sr (mg/L), d Sr on surface (mol/g solid). Ion exchange controls concentrations of these species while mineral dissolution and precipitation play a minor roleBack to article page
