we use water for off stream use?
What is surface water? What is ground water?
What is the water table?
What percent of water is used for farming?
What is irrigation of crops? What are the different

Paragraph 2: Water pollution
What is water pollution?
How does the Hudson River Case Study (Botkin
and Keller, 2010, p. 399) exemplify water pollution
and remediation efforts?
What is the difference between point source
pollution and non-point source pollution?
What is surface water pollution and what is
ground water pollution?
What are water borne diseases, and what bacteria
is used as measure of disease potential?
What is dissolved oxygen? What is biochemical
oxygen demand? How are they related? How does
dissolved oxygen effect ecosystems?
What were your finding on the sewage lab? What
happens to biochemical oxygen demand and
dissolved oxygen when excess sewage/waste is
added to an aquatic system?

Paragraph 3: Eutrophication (water pollution + biogeochemical nutrient cycling)
What is Eutrophication? How does it most
frequently occur (link to agriculture)?
Describe the steps (in sentence form) that occur
when excess Nitrogen and Phosphorus enter into
aquatic systems, causing Eutrophication.
For your first trail of this lab, you tested for 3
compounds containing nitrogen: ammonia, nitrite
and nitrate in waste water that excess synthetic,
inorganic fertilizer in it. Which of the 3 nitrogen
compounds was the highest?
How do Biogeochemical cycles of Nitrogen,
Phosphorus and Carbon connect soil and water
(abiotic) systems within an ecosystem?

Paragraph 4: Water treatment
Septic tanks are usually used in rural areas (farm
land) How does a septic tank work?
How does a water treatment plant work?
What are primary and secondary treatment?
What does chlorine treatment do?
What happens at the filtration step in the water
treatment process? How does soil act as a water
filter for rain water percolating through?
What is percolation? How it affected by
permeability and porosity of the soil?
How would soil texture and composition affect
fertilizer run off into aquatic systems (such as

Paragraph 5: Your Experimental Design
What is remediation? What is phytoremediation?
What is Bioremediation? How do biotic (living)
affect abiotic (non-living things), such as soil and
water? (think nutrients)
What will you use to build your water filter? Why?
What is the purpose of your experiment? What is
the essential question you are trying to answer?
What is your independent variable? What is your
dependent variable?
What is your hypothesis? (must be an “If… then…”

APA format
All your paragraphs should have sources cited in APA format. That means that there are in text citations,
and a works cited page at the end of the paper. There are a lot of rules when it comes to APA format, so
here is simplified cheat sheet for the basics.
Works cited page (belongs at the back of the paper)

According to author (1998), "Students often had difficulty using APA style, especially
when it was their first time" (p. 199).
