Lab 2 – Water Quality and Contamination
iExperiment 1: Effects of Groundwater Contamination
|Table 1: Water Observations (Smell, Color, Etc.) |

a. Oil hypothesis = oil will not contaminate, but possibly the amount of water filtered may change.
b. Vinegar hypothesis = vinegar will contaminate and would allow the soil to filter
c. Laundry detergent hypothesis = Laundry detergent, the water would pass through but will be contaminated with soap bubbles.
2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this.
a. Oil hypothesis accept/reject = I accept because the oil went through the soil like I expected.
b. Vinegar hypothesis accept/reject = I reject because I thought the soil would have stopped the vinegar from getting to the water
c. Laundry detergent hypothesis accept/reject = I reject because like with the vinegar I thought the soil would have stopped the detergent.
3. What effect did each of the contaminants have on the water in the experiment? Which contaminant seemed to have the most potent effect on the water?
Answer = we all know that oil and water do not mix. The oil sits on the top of the water no matter how fast you mix it. Vinegar mixes well with the water and does soap. The difference is you cannot tell the vinegar in the water unless you smell it. When you add soap to the water it produces bubbles and has a cloudy to look it. I think they all have a potent effect although vegetable oil and vinegar may not kill you if you drink the water. It is still not a good mix with water for drinking, maybe the soap is most potent to me because you can sick if you drink soapy water. It says on the bottle to call poison control if ingested. Not a good combination and could cause illness or even death if this were contaminated water.
4. Using at least one scholarly source; discuss the potential effect of each contaminant (oil, vinegar, and detergent) on the town’s water source and the people who drank the water.
Answer = the 1980’s saw an increase in response to two new hazards world, polychlorinated biphenyls (PCB’s and asbestos every incident required a hazmat response and decontamination process PCB’s were oily, so I used strong soaps to initiate the process. Asbestos was a solid, so I instituted filtration of” the gray water” effluent to protect the environment and control the spread of contamination (Doherty, V.J. 2011)
If we were to have our water contaminated by soap, oil, or vinegar, people could become sick although oil and vinegar are not necessarily contaminated, it is still contaminating our water.
5. Describe what type of human activity would cause contaminants like oil, acid, and detergents to flow into the water supply. Additionally, what other items within your house do you believe could contaminate the water supply if you were to dump them onto the ground?
Answer = car accidents can cause oil...
