Supportive Water Quality Sampling
We will collect water samples for laboratory analysis and perform a variety of field measurements to provide supporting data for the many indicators being developed.
Field water quality measures include depth-profiles of temperature, dissolved oxygen, pH and specific electrical conductivity (a measure of the total dissolved salts or ions). We will also be measuring water clarity using a standard secchi disk and using a turbidity tube (as used in many stream volunteer sampling programs).
Some water quality parameters have to be measured in the laboratory. These include nutrients (nitrogen, phosphorus, silica), organic carbon, color, alkalinity, turbidity, total suspended solids, chlorophyll and chlorophyll fluorescence.
Our intent is to evaluate both relatively inexpensive measurements that can be made "in the field" and the more expensive analyses typically used to characterize water quality.
