Sampling Parameters
Each year, two sampling events are conducted at each of the sampling sites. One sample is collected in the spring and one in the fall. Students do all of the sampling at the sites selected by their school. Data has been collected since 1996.
During each sampling event, a number of parameters are determined or tested for. They are:
Physical Parameters
Ball Habitat Rating Steam
flow
Temperature
pH Turbidity
Biological Parameters
Macroinvertebrate sampling
Bacteria count of fecal coliformChemical Parameters
Dissolved oxygen
Biochemical oxygen demand
Total phosphate
Nitrates
Total solids
The methodology used for collection and analysis of samples is described in Field Manual for Water Quality, by Mitchell and Stapp.
