Remediation

The measures we took in the soil remediation process were that we needed to increase the nitrogen within our soil. Our group decided to use unused bags of tea to increase nitrogen levels naturally. We used exactly 4.5 grams of unused tea for each pot of soil. We added the tea after we planted the seeds to secure that each plant received the same exact amount of added nutrients. For each pot we decided to fill it mid way with soil to secure that we had enough samples for testing. Each pot received three lettuce seeds which were planted about mid way of the soil sample. After planting the seeds and adding the 4.5 grams of unused tea to half of the samples we watered the pots. For each pot even those that we did not increase the nitrogen levels, we added 10 mL of water every Monday, Wednesday, and Friday. We took turns on which days each team member would water the plants to secure that everyone had a chance to participate equally with the caring of the plants after remediation occurred. Our expectations were for the lettuce samples that were in the soil samples with the unused pots to grow more than the seeds on the soil samples without the tea. We expected this because the invrease in nitrogen would help the nutrients be sufficient for the growth of the plants.
