Station 0: Pristine Forest
This is a forested area which is relatively undisturbed by human activity.
It is heavily shaded and cool with dense ground cover, so very little run-off.
Q11. How does D.O. at Station 0 compare to Station 3?
Why do they differ?
Going Further:
1. Compare pollution indicators for other stations with Station
0, which has the best possible conditions
2. As you compare different stations, and make improvements try to make predictions before you select changes.
3. Investigate other pollution indicators such as sediments and
pH.
The easiest way to compare stations and effects of improvements,
is to write down max. values for pollution indicators (or min. for D.O.
and pH)
You can keep track of these numbers in the Notepad.
4. As you make improvements at different stations, you should begin to see some improvements at the River Mouth, Station 7. This in turn should result in improvements in the Bay, Lake, Gulf or Ocean that the river flows into. Biodiversity should increase as water quality improves!
5. Total Loads: When examining the data, notice the Total Loads (on right side of graphs), especially for nutrients and toxins. Rivers and streams move pollutants like conveyor belts to larger water bodies, such as bays, where they accumulate. BMPs, reducing runoff can have a much more positive effect in decreasing loads, even though there may be only a slight decrease in concentration of the pollutant.
