Abstract:
In the village of Gopher Hollow there’s a cluster of Blue Baby Syndrome. There were four infants affected by this cluster. The families from the infants would collect their water from wells. We have to determine what’s the source of the high levels of nitrites in the water. The four sources that could be the point of contamination are a new subdivision, textile plant, an organic farm, and a mountain lake. We had to find the concentration of each known standard and unknown standard. We did this by using a spectrophotometer. The results were the following, the organic farm with a herd of 50 cows and a 10 acre field of zucchini had the highest levels

Discussion:
Based off the results that we got from the experiment the main source for high levels of nitrites in the water was sample C. Which was the organic farm with a herd of
50 cows and a 10 acre field of zucchini. The hypothesis did not support the final result.
The highest level of nitrites was 7.07 ppm which was accurately found using the best fit line.(Figure 4) From this result it was disproven that the mountain lake would be the cause of high levels of nitrites in the water. The results supported the cause of Blue baby syndrome and how the organic farm was the main source of the contamination of the water. Which caused the high levels of nitrites and causing the cluster of blue baby syndrome in the village of Gopher Hollow.

    This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982, copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating…
