Because of this, watershed-scale, water quality models often have poor bacterial prediction capabilities. To improve the understanding of in-stream bacterial transport, a cow pie was deposited in a recirculating flume with flows ranging from 0.0102 to 0.0176m3 s−1. Water samples were collected and analyzed for Escherichia coli concentration, E. coli attached fraction, and turbidity. E. coli concentrations ranged from 4.72 × 103 to 1.70 × 105 CFU 100mL−1 and turbidity ranged from 1.93 to 369NTU over both locations and all times. The percentage of E. coli attached to particles ranged from an average of 2.9 to 31% downstream of the fecal deposition point. Spearman correlation analysis demonstrated that bacteria concentrations were significantly related with water depth (ρ = 0.128, p = 0.018), and the concentration of attached bacteria was significantly correlated with both the total concentration of E. coli (ρ = 0.4081, p = 0.009) and turbidity (ρ = 0.3627, p = 0.0214). This analysis is useful to indicate parameters that should be considered when monitoring or predicting bacteria transport in streams.
