By Emily, Veronica, and Shelby

(Group #1)

Assignment To develop a few hypothesis about

the Fourmile watershed, in order to demonstrate our knowledge of Watersheds and water quality issues

Methodology

Day 1- Chemical Test Water Samples, Watershed Lecture

Day 2- Visited Big Darby Watershed, Ran Chemical Tests, Measured ICI And IBI. Demonstration Of Electro Fishing By Ohio EPA

Day 3- Model It (Independent Vs. Dependent Variables)Excel SpreadsheetsGathered Information About The Fourmile Watershed

Day 4- Learned Power Point PresentationCompared Fourmile and Darby Watershed on SpreadsheetsMade Three Hypotheses by Comparing Data to Station LocationMakes Graphs of the Data

Day 5- Presentation SkillsPower Point ProjectCreate Web SiteWomen of Achievement Panel

Day 6- Practice PresentationsComplete Web SiteComplete Power Point Project

Methodology 2

Definition Page 1IBI = Index biotic integrityICI = Invertebrate community indexQHEI = Qualitative habitat evaluation index DO = Dissolved OxygenTSS = Total Suspended SolidsStation ID = Number representing where the tests were done

Point Source Pollution = A known source of pollutionNon Point Source Pollution = An unknown but suspected source of pollutionRiparian Zone = A type of habitat associated with lush vegetationMeander = a natural curve or turn in a creek or river bedBOD = Biochemical Oxygen Demand

Hypothesis

H1: When the QHEI (Qualitative Habitat Evaluation Index) increases, the ICI (Invertebrate Community Index) and the IBI (Index of Biotic Integrity) increase

H2: The closer the creek is to the city the lower the ICI and the IBI

H3: The TSS (Total Suspended Solids) increases in agricultural areas

Hypothesis #3

Results H1:The hypothesis is correct. When the QHEI

increased the ICI and IBI increased. H2: The hypothesis is correct. Due to the location

of an urban setting the ICI and IBI levels decrease near the city and increase near the rural areas.

H3: The hypothesis is correct. This hypothesis was also based on location and the TSS level was higher if it was near a rural area, rather than an urban area.

Conclusion We tested our hypotheses and we

concluded that, according to our research, our hypotheses were all correct.

All of our graphs based on our research showed that we came up with the correct hypotheses about our watershed.
