Environmental Engineers

Mixed — a routine tier and a judgment tier. AERMOD and MODFLOW runs, Title V permit renewals, Phase I ESA records reviews, and DMR/quarterly monitoring reports are templated enough that a model plus a script covers the first draft, which is why this sits at 10 rather than 15 — the remaining half is sizing a pump-and-treat system or an SVE array against site conditions no dataset describes.

Some physical or field component. You are on site for tank pulls, soil boring oversight, outfall and stack-test observation, and post-remediation confirmation sampling, but that is weeks a year in steel toes and a hard hat rather than daily — the bulk of the work happens back at a desk, which puts it at 9 instead of the 14+ a field geologist or industrial hygienist would earn.

Licensed human required and personally liable. The PE stamp on a remediation design, a stormwater or landfill closure plan, or a treatment-system spec is a personal legal exposure under state engineering practice acts, and NPDES and RCRA filings name a responsible engineer — 13 not higher because plenty of environmental engineering work (ESAs, permit support, compliance auditing) is legally performed unstamped by staff who never sit for the PE.

Some relationship component. Agency reviewers and plant managers come back to the engineer who has run the last three inspections at their facility and knows which state DEQ reviewer will accept an alternate compliance schedule, but the deliverable is a signed and sealed report reviewed on its technical content, not the name on the cover, so it lands at 9.

Meaningful discretion. Calling a site closed under a risk-based cleanup standard, choosing MNA over active remediation, or deciding a release is reportable under CERCLA 103 are consequential judgments with imperfect data and real downside — 13 rather than 17 because most of these choices are bounded by promulgated cleanup levels, state guidance documents, and a client and agency who both sign off before anything moves.
