River Run Water Quality Questions
Complete the following questions using The Data Visualization Tool, River Run. HINTS are given to help locate data and answer questions. Use this tool to explore your knowledge of water properties.
ŕ
Is there a relationship between the amount of rain and the turbidity of the
water?
If yes, what is the relationship?
HINT: look at CFR and
click “Plot multiple dates at one site”, select NC11 site, look at March
1998. Select “Rain Data” to view the amount
of rain received that month (hold the cursor over the rain clouds to determine
the amount of rain received)
Is this true for both rivers?
Is this what you predicted? Why
or why not?
ŕ
Describe the relationship between Temperature and Dissolved Oxygen.
HINT: look at CFR and
click “Plot multiple dates at one site”, select NAV site, look at the dates at
this site
Water temperature
is important to everyone and everything around it – swimmers, fisherman,
industries, and even fish and algae. Power plants that generate electricity use
large amounts of water for cooling purposes. They need cool water to start
with, and generally warmer water is released back to the environment. The
temperature of the released water can affect downstream habitats by changing
the overall water temperature. Temperature also can affect the ability of water
to hold oxygen, which would mean a decrease in dissolved oxygen levels.
Do nitrate and phosphate exhibit this
relationship?
HINT:
the “XY Plot Parameters” need to be changed
Is this what you predicted? Why
or why not?
ŕ
What is the relationship between the amount of rain and the dissolved oxygen
and Temperature of the water?
Is this relationship the same during the
winter and summer?
Is this what you predicted? Why
or why not?

Compare fecal coliform and turbidity on the
What is the relationship between these
two parameters?
HINT:look at CFR and click
“Plot multiple dates at one site”, observe the following sites: NC11, AC, and
NAV. Look at the following dates: March 1998, September 1998, and January 1999.
Is this what you predicted? Why
or why not?
Do these patterns remain consistent
throughout the different months of the year?
Is this relationship the same for the
HINT: look at NECFR and
click “Plot multiple dates at one site”, observe the NCF117 site and look at
the following dates: March 1998, September 1998, January 1999
Does rain have an impact on the
relationship between these two parameters?
