Controlled Experiment

This test was run alongside the remediation process. A small cup was filled with our original soil sample (left), six lettuce seeds were planted, and the soil was watered around once a day over approximately one week:
Over the course of a week, a couple seeds of the lettuce actually began to grow, resulting in a stalk after three days:
And a few days after, now with full leaves:
By the end of the experiment, two stalks of lettuce saplings had begun to grow with a third on the way, and are still growing as I write this post; a stark difference from the lack of any life found in the "remediated" soil:
This shows that our soil sample was at least moderately healthy and fertile as it was, and leaves little to compare to as the "remediated" sample yeilded nothing. Many other groups, though not all, were also seen to have had greater success with their initial samples rather than samples after remediation. A taste test was unable to be done (and I assume could not be unless given months to let the lettuce grow to edible size), but it can be assumed that the lettuce in the natural soil would be healthier and taste better than anything that would have come out the the failure that was the remediated soil.
