Figure Lengend Snippet: Percent wastewater versus fluorescence of TRP (left) and CDOM (right) from Aqualog (top) and Manta (bottom) for three wastewater addition experiments ( Table S2 ). Manta TRP and CDOM are without turbidity correction due to low turbidity. TRP TC is TRP corrected for turbidity using eq and was performed only for Seawater1 due to the small impact of turbidity correction.

Article Snippet: Samples were filtered through 0.7 μm pore size glass fiber filters and fluorescence spectra were acquired on the filtered samples using the benchtop Horiba Aqualog fluorometer ( Section ).

Techniques: Fluorescence

Figure Lengend Snippet: E. coli concentrations versus TRP (left panels) and CDOM (right panels), on logarithmic axes, for the benchtop Aqualog (top), in situ fluorometer (Manta) without turbidity correction (middle) and Manta with turbidity correction (bottom), k = 0.00065 for TRP, k = 0.0008 for CDOM). The red circles indicate Tukey outliers.

Figure Lengend Snippet: Time series of discharge and percent wastewater (pctWW) for each sampled event, predicted using the observed Aqualog TRP values in the Tijuana river water as input to the pctWW-TRP regression calibrated to the wastewater addition experiments. Three predictions of pctWW are included, one for each WW addition experiment ( Figure ).
