Exposure Monitoring for the Golden Triangle
Beaumont, Port Arthur and Orange form the "Golden Triangle" — home to some of the largest refineries in the United States, major petrochemical plants, LNG export terminals and shipyards along the Sabine-Neches corridor. AGT Labs is the accredited industrial hygiene lab behind that work, analyzing benzene, H₂S, welding fume, silica, lead, asbestos and mold in-house in Houston with overnight courier from Southeast Texas.
Whether it's routine compliance monitoring, a scheduled refinery shutdown, or shipyard and LNG construction, we support Golden Triangle employers and contractors with fast, defensible data. See our refinery IH testing, turnaround air monitoring and shipyard & marine programs.

Who We Serve in the Golden Triangle
Southeast Texas concentrates some of the highest-hazard, most heavily-regulated work in the country — exactly where accredited exposure data matters most.
Refineries
Among the largest US refineries — benzene, H₂S, PAH, catalyst metals and turnaround monitoring, plus Legionella culture on cooling tower water.
Petrochemical Plants
VOCs, butadiene, formaldehyde, isocyanates, acids/alkali and airborne metals.
LNG Export Terminals
Sabine Pass and Gulf LNG construction — welding fume, hex chrome, silica and lead.
Shipyards & Marine
Orange and Sabine-area yards — blasting silica, lead, welding fume and asbestos.
Industrial Contractors
Turnaround, maintenance and abatement crews needing fast, defensible results.
Facilities & Commercial
Indoor air quality and mold assessments for offices, warehouses and public buildings.

Industrial Hygiene in the Golden Triangle
What Refinery Row and the Sabine-Neches LNG corridor mean for your exposure monitoring.
Beaumont, Port Arthur and Orange — the Golden Triangle — hold one of the densest refining and petrochemical corridors in North America: Motiva's Port Arthur refinery (the largest in the U.S.), ExxonMobil's Beaumont refinery and chemical plant, and the Valero and TotalEnergies Port Arthur refineries, along the Sabine-Neches Waterway. Refining at this scale drives heavy benzene, hydrogen sulfide and polycyclic aromatic hydrocarbon exposures, while the coker and heavy-crude units add sulfur and metals concerns. The corridor's LNG build-out — Golden Pass and the Sabine Pass terminals nearby — plus the shipyards and fabrication yards on the waterway bring welding fume, manganese, hexavalent chromium and abrasive-blasting silica into the mix. Every one of these analytes is analyzed in-house at AGT. Refining at this density also means a large installed base of cooling towers — a source CDC identifies for Legionella aerosol — so Legionella culture on cooling water belongs in the same water management programme as the air panel.
This is Jefferson and Orange county work, so monitoring may answer to TCEQ and regional air programs as well as OSHA, and marine and shipyard operations fall under OSHA's maritime standards rather than general industry — a distinction that changes both sampling strategy and the limits your data is judged against. Demolition and vessel-refit work also trigger Texas DSHS asbestos requirements. From the Golden Triangle, samples reach our Houston lab by overnight courier or priority freight, with rush analysis available so a turnaround, a confined-space entry or a clearance stays on schedule.
