| Methods: |
A concentrated stock of sodium bromide was
injected at -29 meters. The channel locations were instrumented
at 3 meters and 33 meters with Orion bromide selective electrodes
to monitor instream bromide concentrations and guide the
collection of physical samples. Physical samples were collected
at irregular time intervals weighted to cover the rising and
falling limbs more intensively than other time periods. Upon
return, the physical samples were analyzed by HPLC on a Dionex
AS4A Anion column with detection of 10 ug/L. The table below
contains the solute injection parameters.
Injection Start: 0 minutes
Injection End: 215 minutes
Stock Concentration: 485473 mg/L
Injection Rate: 55.3 mL/min
Notes: Distances reported are relative to the 15N
dripper location.
