Lab 2 Essay Example
Lab 2 – Water Quality and Contamination
Experiment 1: Effects of Groundwater Contamination
Table 1: Water Observations (Smell, Color, Etc.)
Beaker Observations
1 Water is perfectly clear/No odor
2 It was cloudy with an oil sits on top of the water/no odor
3 This sample had a slight odor which was mostly unidentifiable and had good clarity
4 Bubbles formed on surface and had a cloudy appearance /no odor
5 Some sediment in water and brown in color /no odor
6 Water is brown in color with some sediment. No odor present and still a presence of oil that collected in the soil
7 Water is brown in color with some sediment. Has strong odor
8 Water was dark brown. The soap bubbled in soil and had a light brown film on top of water
POST LAB QUESTIONS
1. Develop hypotheses on the ability of oil, vinegar, and laundry detergent to contaminate groundwater.
a. Oil hypothesis =
b. Vinegar hypothesis =
c. Laundry detergent hypothesis =
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 =
b. Vinegar hypothesis accept/reject =
c. Laundry detergent hypothesis accept/reject =
3. 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 =
4. 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 =
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 =
