6. Salinity
Dissolved salt
content of a body
of water

7. Conductivity A measure of the ability of water to pass
measured in micro siemens per centimeter (μS/cm)
A measure of the
ability of water to pass
an electrical current.
Affected by presence
of inorganic & organic
dissolved solids

8. Temperature
-Critters sensitive to temperature: Salmonids, Salamanders, Frogs, ect...
-Regulated by riparian vegetation, temperature outside, and other factors (can you think of any?)
-We will take multiple readings at multiple locations (the more data the better!!)

9. pH (Acidity) -The concentration of H+ ions in an aqueous solution
-Scale from 0 to 14
-Neutral (pure water) = 7
-Higher concentration = acidic
-Lower concentration = basic

10. Dissolved oxygen -Very important in helping organisms breathe
-Dense reed canary grass
has altered this process,
reducing the amount of D.O
-Measured with

11. Turbidity -The amount of sediment suspended in a sample of water
-Organisms see further in
water with lower turbidity
-Measured with a light
refracting device called a
turbidimeter

12. Final Thoughts Water quality is very important for all of us.
Measure different variables to determine how pristine the water is.
Several Chemical reactions and/or processes determine water quality.
Find the negative factors and change them. (reed canary grass invasion->low D.O.->remove RCG)
