Introduction:
For Science 100’s final task the groups where given a lab to test for water quality in any body of water around the campus of UMBC or relatively close to your home. So my group decided to test the Patapsco River near Ellicott city and the Northwest branch of Anacostia River in Silver Spring. With Ellicott city being in a rural location compared to sliver spring we wondered which body of water would be cleaner. From everything we learned in class and the Documentary from frontline we understood polluted water has an increased rate of happening in the city because of construction, sewage, and water run off. Once we got the samples from both rivers back to the lab we commented on how brown and murky the water was. This may have been due to a storm from the previous night that flooded Ellicott City and rained in Silver Spring. Where the sample was taken for the Patapsco river it was a manmade waterfall/dam the sample from Anacostia was set dirtier than Patapsco River. This is due to Anacostia being surrounded by a more urban area. (Fahrenthold,2010) So based off of the observations we made by looking at the water samples and the surrounding area we predicted that the conductivity, phosphates and nitrates of the Northwest Branch of the Anacostia will be higher than the Patapsco, and that the turbidity of the Patapsco water sample will be higher than the Anacostia River.

Methods:
In this experiment we tested for turbidity, phosphates, nitrates, and conductivity.
Conductivity was the first test we did using labquest conductivity tester we placed probe into water to measure. (Ahuja,2013) Conductivity Measures the conductance of the water with an electric current. For both rivers, we took 80ml sample at temperature of room. ...

...ed vials, and 5mL of mixed acid reagent into samples. We shook both samples and wait 2 minutes before starting to invert then added 0.1g of nitrate reducing reagent. We shook both samples for 4 minutes then turned then upside down and waited 10 minutes. On the screen we selected “All TESTS” from testing menu and scrolled down to 064 Nitrate-N LR and hit select. We wiped the vail down and testes the sample blank before we tested the actual river water.
The final test we did was turbidity. Turbidity measures water clarity. For both rivers we cleaned 4 vial with distilled water to ensure it is clean. Then filled the sample blank vials with 10ml of water using 2ml pipets. On the screen we selected “All TESTS” from testing menu and scrolled down to 098 Turbidity and hit select. We wiped the vail down and testes the sample blank before we tested the actual river water.

Testin the Quality of Water Essay

- Introduction During lab on Monday, April 9, 2002 our class conducted a lab on water chemistry and pollution. The two bodies of water that were choose as samples where, the Wall pond and the HGTC pond. Each group had to test the water for Temperature, Dissolved Oxygen, Nitrate, Phosphate, pH, and Turbidity. Only two people where chosen to test the waters for Coliform bacteria. “Coliform bacteria are not pathogenic (disease causing) organisms, and are only mildly infectious. For this reason these bacteria are relatively safe to work with in the laboratory”....   [tags: Water Quality Lab Report]

A Proposal to Protect Drinking Water Quality Essay

- The purpose of this report is to propose a solution to the problem of reduced drinking water quality due to chemical pollution. Some bodies of water in the United States are becoming polluted from chemicals and restrictions are needed to protect drinking water quality. THE BACKGROUND OF CHEMICAL USE AND WATER QUALITY Drinking water quality was not a concern until the last century when the use of chemicals was greatly expanded. Chemicals are used to kill weeds, insects, and other pests. Chemicals are typically sprayed on an area and are designed not to harm the crop, grass, or other plants that you want to remain....   [tags: Drinking Water Quality Essays]

Essay on Water Quality Of Water Treatment

- Living in a world that is roughly 70% water, and all living creatures found on this planet depend on this resource whether directly or indirectly, making water quality an important topic and vital to sustain our world of cycles. “Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands.” (Bai V, 2009) With most of our water on this planet made of salt water and our constant damage towards the remaining water that can be consumed by humans is diminishing with improper distribution on a global sca...   [tags: Water, Water pollution, Water quality]

Essay about Water Lab Report

- Water is a charged or polar molecule (H+ - O- - H+) that is always moving across cell membranes. Scientists theorize that this is possible because it is such a small molecule or because there are special gap or pores that allow water movement through the cell membrane. The predominant direction of water flow is determined by the concentration of the solutes (non-water molecules) inside and outside of the cell. Water molecules will show a new movement from an area of higher water concentration (& lower in solutes) to an area of lower water concentration (& higher in solutes)....   [tags: Lab Report]

Maintaining Drinking Water Quality Essay

- 26,895 Boston Marathon runners run down streets for miles and miles. Whenever a runner gets tired they run to a side spot and chug a glass of fresh, clean water. However, clean drinking water is not so redily available to everyone in America. There are nearly 55,000 community water systems in this country, supplying water to meet the drinking needs of more than 90 percent of the U.S. population. The Environmental Protection Agency (EPA) defines a community water source as one that consistently provides water to at least twenty-five percent for at least sixty days during the course of a year....   [tags: Potable Water Quality]

Bottled Water Quality vs Municipal Drinking Water Quality Essay

- "If we paid as much for tap water as we do for bottled water, most people would have a monthly water bill of over $9,000." - -Andrew C. Revkin - The New York Times It is very common for research groups to set up a "bottled water taste test". The results are always the same: without a label, there is no obvious difference among any kind of bottled water or even tap water. Yet millions of Americans routinely buy bottled water and re-filter their tap water. The Clean Water Act of 1972 was supposed to ensure all water sources were pure and safe for drinking or swimming....   [tags: Drinking Water Quality]
