Water-Column Studies

What is Water-Column Studies?

Water-Column Studies meaning Investigations of physical and chemical characteristics of stream water, which include suspended sediment, dissolved solids, major ions and metals, nutrients, organic carbon, and dissolved pesticides, in relation to hydrologic conditions, sources, and transport. These studies also involve selected studies of other water-quality conditions and include selective investigations of hydrophobic organic contaminants or trace elements where their importance is indicated by results of Bed-Sediment and Tissue Studies. Water-Column Studies have three main components–Basic and Intensive Fixed-Site Assessments and Water-Column Synoptic Studies.
