Brief Method Summary
|
The main factors to consider in selecting a water-quality monitoring site are the purpose of monitoring and the data-quality objectives. All other factors used in the site-selection process must be balanced against these two key factors. Defining the purpose of monitoring includes making decisions about the field parameters to be measured, the period and duration of monitoring, and the frequency of data collection. Stream characteristics, site characteristics, and data-quality objectives determine whether a data sonde will be placed in situ (fig. 1) or whether a flow-through receptacle with a pump- ing sampler (fig. 2) will be a better choice. More site-specific considerations in monitor placement include site-design requirements, monitor-installation type, physical constraints of the site, and servicing requirements. |
