Scenario: A local community is facing groundwater contamination with pesticides. You are tasked with proposing a potential solution using hydrogenation.
Task: 1. Briefly explain how hydrogenation could address this contamination problem. 2. Identify one potential challenge and propose a solution to overcome it.
1. Hydrogenation can effectively address pesticide contamination in groundwater by breaking down these organic molecules into less harmful or easier-to-remove substances. The process involves adding hydrogen to the pesticide molecules, altering their structure and reducing their toxicity.
2. A potential challenge is the high cost associated with implementing hydrogenation on a large scale, especially for groundwater remediation. One solution could be to explore partnerships with industrial sectors that already utilize hydrogenation processes, potentially sharing infrastructure and resources to reduce overall costs.
