Description

Radium isotope results surface water runoff from Little Lagoon(LL), Lake Shelby(LS), Canal(C), and Pass(P) samples in and around Lake Shelby, Alabama. These data are part of a study to assess submarine groundwater discharge.

Results, methodology, summary tables and instrumentation are included in:
