Development of an autonomous flow-proportional water sampler for the estimation of pollutant loads in urban runoff

Abstract: Implementation of an extensive urban runoff monitoring program, targeting the quantification of heavy metal and organic micropollutant loads, necessitated the development of an autonomous water sampler. The design requirements for the device were to fulfill flow-proportional continuous composite sampling of urban runoff events in a widely customizable, relatively inexpensive, and simple way. In this paper, we introduce the concept along with the experiences gained from the first several months of field tests a… Show more

“…Proportional (i.e., flow‐weighted) samplers, by contrast, are designed so that the amount of water collected is related to runoff quantity. This sampling protocol is particularly useful for environmental monitoring studies, since, for example, it can be used to calculate pollutant loads (Bonta, 2002; Budai et al., 2020; Pinson et al., 2004). A variety of flow‐weighted sampling approaches exist, depending in part on the type of runoff measurement system being used.…”

“…At the same time, flow divider systems can fail to sample small runoff events (Carter & Parsons, 1967), and the systems can become clogged with sediment. Other flow‐weighted samplers rely on pumping units and control units (Budai et al., 2020), which can provide accurate samples but also may require extensive maintenance and a continuous power supply.…”
