POST LAB QUESTIONS Develop hypotheses on the ability of oil, vinegar, and laundry detergent to contaminate groundwater. Oil hypothesis = Oil will not contaminate or change the amount of water filter. Vinegar hypothesis = Vinegar will contaminate through the soil allowing the water to filer through. Laundry detergent hypothesis = Laundry detergent will contaminate the soil by allowing the water to pass through. 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. Oil hypothesis accept/reject = Accept// Oil is trapped in the soil. Vinegar hypothesis accept/reject = Accept// Vinegar passed through the soil, because it change the viscosity of the water. Laundry detergent hypothesis accept/reject = Reject// Laundry detergent also changed the viscosity of the water. What affects 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 = From what I observed, oil is saturated into the soil leaving little to none of the water to pass through. While the vinegar passed through the soil leaving more dirty water. Based on what I think, vinegar is saturated and a natural substance while oil is a man made product and a much thicker substance. Oil absorbed the soil leaving the water less contaminated. My conclusion, vinegar was the more potent liquid. Using at least 1 scholarly source, discuss what type of affects these contaminants (oil, vinegar, detergent) might have on a town’s water source and the people who drank the water? Answer = "When water chokes you, what are you to drink to wash it down?"
