In this assessment, you will examine local and national water quality issues, and demonstrate your understanding of hydraulics, hydrology, and water pollutant detection and treatment. Reference the resources you used to determine your answers. Cite in APA format.

 

1. List three primary water pollutants in the U.S. and in your present location in the U.S. (or U.S. hometown if you are presently living abroad).  Clearly identify your location (city and state).  For each of these pollutants, identify the local and/or federal regulations it violates.  (15 points possible)

2. Identify the major sources of these pollutants in the U.S. Compare and contrast (similarities versus differences) the presence of major sources of the pollutants at the national level with those in your local area.  Discuss factors that dictate the differences in the prevalence of major sources of pollutants at the national level and at your local level. (10 points possible)

3. Explain one technology that you can use to analyze your local water sample.  Which of the water pollutants you identified for your local area can be detected, and to what sensitivity, using this analytical technique?  What other contaminants could also be detected and to what sensitivity using this technology? (15 points possible)

4. Research three different types of water treatments available for contaminated water.  Explain the basis of each treatment and what pollutants each treatment mitigates.  What level of mitigation is needed and does that treatment typically bring the contaminants down to that level? (25 points possible)

5. Explain how one of the pollutants you identified is carried or treated through the hydrologic and biogeochemical cycles.  If there is no treatment for this pollutant via the hydrologic and biogeochemical cycles, explain why.  If the pollutant is treated in the hydrologic and/or biogeochemical cycles, explain the physical, biological, and/or chemical basis of that treatment. (10 points possible)

6. Assume that the contaminated water is to be used for drinking. Using principles of hydraulics, calculate the diameter of a cast iron pipe needed to obtain steady uniform gravity flow of about 0.04 m3/sec given a grading of 0.5% slope.  Show/explain how you obtained your answer. (15 points possible)

7. Provide all appropriate references and citations in APA format. (10 points possible)
