“…The simple siphon samplers were constructed from a modified design of Newham et al (2001), based on the original USGS design of Graczyk et al (2000). Siphon samplers have been found to be successful for sampling rapidly rising streams (Graczyk et al, 2000). The samplers comprised a 1 L HDPE plastic bottle connected to 8 mm internal diameter vinyl tubing for a siphon system via a rubber stopper, all contained within a 110 mm outside diameter PVC pipe.…”

“…Siphon samplers, constructed similarly to Graczyk et al (2000), were used to collect water samples during storm flows. They were positioned next to the stream at 10 and 30 cm above base flow.…”

“…However, at higher flows and higher solids concentrations, the differences between fixed-point autosamplers and cross-section, depth-integrated samplers is small (Bent et al, 2001;Breault and Granato, 2000;Horowitz et al, 1990;Krug and Goddard, 1986), such as the ,20% difference noted in sediment concentrations between paired samples collected with a fixed-point autosampler and a cross-section, depth-integrated sampler (Bossong et al, 2006). However, the differences remain high (40%) at low solids concentrations (Graczyk et al, 2000).…”

Regulatory agencies approve automatic samplers containing peristaltic pumps as a sample collection method for stormwater characterization and for treatment-device evaluation. Autosampler performance, as discussed in the limited available literature, can vary across the entire particle size range typically found in stormwater from different source areas and outfalls-reasonably consistent performance for particle sizes ,250 lm, but much less consistency for particles .250 lm. Therefore, a series of experiments was undertaken to quantify the upper range of consistent particle capture that may occur with sampling stormwater suspended sediment and particulate-bound pollutants. These experiments, based on triplicate sampling at each experimental condition, found that peristaltic pump autosamplers commonly used in stormwater monitoring could not repeatedly and effectively capture particles .250 lm from a simulated stormwater whose particles have a specific gravity of 2.65. It was expected that the effective size for autosamplers would be correspondingly larger for particles having smaller specific gravities. The height of the sampler had no influence on particle recovery up to a height of 2.5 m, with slightly decreasing recoveries of large particles occurring at greater heights, as a result of reduced sampler intake velocity. Therefore, to characterize the solids across the entire size range and specific gravities that may occur in stormwater runoff, autosamplers should be deployed in conjunction with bedload and floatables sampling.
