How is chemistry connected to environmental science and engineering disciplines?

As an environmental engineering PhD student, I'm drafting a proposal that must justify its chemical basis to a diverse committee. I need a succinct yet comprehensive way to articulate how chemistry is not just a tool but the foundational language for diagnosing and solving environmental problems, from molecular to global scales.

In my career consulting on remediation projects, I've seen chemistry as the essential diagnostic and mechanistic link. Environmental science identifies the problem say, a contaminated aquifer. Chemistry defines the pollutant's speciation, toxicity, and mobility at the molecular level. Environmental engineering then applies this knowledge to design a solution, like a permeable reactive barrier, using chemical principles (e.g., redox reactions, sorption) to destroy or immobilize the contaminant. Without chemistry, you're treating symptoms without understanding the cause.
