Context
No OSHA inspections on record. This does not mean the employer is violation-free — OSHA inspects a small fraction of workplaces annually.

Tetra Tech has no OSHA inspection history on file. Federal records covering wage, environmental, labor relations, and other agencies are noted below where present.

The most recent federal enforcement activity was recorded 1 year ago.

About this data

This profile aggregates federal enforcement records on Tetra Tech from every major federal compliance and enforcement source plus the UVA Corporate Prosecution Registry. OSHA workplace safety inspections, WHD wage cases, MSHA mine safety, EPA environmental enforcement, NLRB labor relations, OFLC visa/labor certification, FMCSA motor carrier registration, SAM.gov debarments, CMS nursing-home records, BLS industry safety benchmarks, OSHA ITA self-reported injury rates, SEC enforcement and financial disclosures, CPSC and NHTSA recalls.

Establishments are matched across agencies using normalized employer name, state, and ZIP code. This establishment resolves to the parent rollup TETRA TECH INC, which operates 56 establishments in our dataset.

OSHA citations typically appear 3–8 months after the inspection, so very recent enforcement actions may not yet be reflected. Profiles may be incomplete if the establishment operates under multiple legal names or files under variations our entity-matching rules don’t yet cover. To report a missing record or correction, email corrections@fastdol.com.
