Watershed

Methodology

• Step 1 We studied the land use map and compared
  the Great Miami to the Big Darby.
• Step 2 We began to compare certain things
  together and began to form hypotheses.
• Step 3 We researched and tested our hypotheses.
• Step 4 We formed our conclusions.

Point Sources of Pollution

• Wastewater treatment plants
• animals wastes from nearby farms
• industrial discharges
• a point source is when chemicals or wastes are
  directly dumped into the stream

5
Non Point Sources of Pollution

• Human activities
• runoffs come from streets, malls, etc.
• non-direct pollution
• when snow melts and runs over the land
• when fertilizer washes over fields into the river
• a non-point pollution is when something is
  indirectly put into the river

Hypothesis 1

• Hypothesis 1 is the more urban areas there are
  the more BOD there is.

7
Did the data support hypothesis 1?

• Yes the data supported hypothesis 1.

8
Conclusion for hypothesis 1

• For hypothesis 1 we discovered through the data,
  when you have urban areas around the river the
  BOD goes up. While agriculture has very little
  effect if any on the BOD in most cases.

9
Hypothesis 2

• Hypotheses 2 is that The IBI rate depends on the
  maximum BOD rate

10
Did the data support hypothesis 2?

• Yes the data supported the hypothesis

11
Conclusion for hypothesis 2

• As the maximum BOD increases the IBI does
  decrease.

12
Hypothesis 3

• The hypothesis is when the total Nitrogen
  increases the IBI decreases.

13
Did the data support hypothesis 3?

• No it didnt support hypothesis 3.

14
Conclusion for hypothesis 3

• The data did not support the hypothesis. Only
  when there was an unusual amount of Nitrogen the
  hypothesis was correct. As youve seen on the
  graph the Nitrogen has no affect on the IBI.
