Geochemical Methods - Development of the MiniSipper, a Segmented Water Sampler
Most estimates of total maximum daily loads (TMDLs) of toxic metals in streams impacted by acid mine drainage are based on a few synoptic (grab) samples combined with stream flow data. However, many important episodic loading events, such as seasonal meltwater and storms, occur on timescales that are rarely observed by traditional sampling approaches.
The goal of this subtask develop a new continuous autonomous integrating water sampler for geochemical hazard monitoring which will provide critical TMDL data for toxic metals in streams affected by acid mine drainage.
- Further improvement of bubble separation between samples.
- Development of an event response MiniSipper.
- Development of a Borehole MiniSipper.
