All sessions include
background information, hands-on instruction
and practice, discussion of method alternatives, quality control,
expected ranges, safety considerations, and interpretation of results.
Physical
Chemistry
The water quality basics,
including pH, temperature, alkalinity, dissolved oxygen, biochemical oxygen
demand, turbidity, total suspended solids and conductivity. Training uses Hach
field test kits and other methods.
Nutrient
Chemistry
Colorimetric and
advanced lab techniques for phosphorus, nitrate, ammonia and chlorine. Includes sample collection, making and using standard solutions and
disposing of waste.
Microbiology
Membrane filtration method
for quantifying E. coli and total coliform bacteria levels.
Includes sample collection,
sterile technique, membrane filtration procedure and calculations.
Macroinvertebrate Inventory
Stream
macroinvertebrates are grouped and interpreted using Hilsenhof and Pollution Tolerance
Indices. Includes field collection, sorting techniques, basic identification and
use of comprehensive manuals and keys.
Riparian
Vegetation
Analyze riparian vegetation based on
2 transects - riparian zone and "greenline". Focus primarily on
percent cover by tree, shrub and ground cover; tree sizes (for large wood
recruitment); and invasive plant species present.
In-Stream
Habitat Assessment
Learn to gather
quantitative data from which a qualitative evaluation can be made. Habitat
parameters include in-stream habitat types, bottom substrate, woody debris,
etc.
Streamflow
Learn
an easy and accurate method to calculate in-stream flow rates.
