What SEMS does
SEMS, Inc. is a privately held environmental management firm headquartered in Baton Rouge, Louisiana, founded in 1992 and operating under founder-family (Morgan) control. The company delivers six integrated service lines — Environmental Consulting, Remediation, Industrial Hygiene, Industrial Services, Demolition, and Specialty Services — to enterprise and government clients across heavily regulated industries including petrochemical, chemical, power & energy, manufacturing, marine, and government. SEMS's revenue model is professional-services, project-based, and quote-driven, with multi-year engagements for ongoing programs (e.g., 40 Oil Water Separator/Sewer Treatment System sites across 10 states) and discrete projects for emergency response, demolition, and remediation. The firm also offers 24/7 emergency response via a dedicated hotline.
Underlying technical capability rests on a multidisciplinary staff of nearly 100 experts (Professional Engineers, Professional Geologists, Certified Industrial Hygienists) supported by owned specialized equipment including vacuum trucks, Vac-Con combo units, hydro-excavation rigs, and high-reach demolition machinery. Differentiated offerings include in-situ chemical oxidation (ISCO) injection, bioremediation, PFAS/PFOA/PFOS treatment, NORM surveying, and integrated assessment-to-remediation workflows. The firm is licensed in more than 20 states, holds an EMR rating of 0.78 (below the 1.0 industry average), and has documented 1,000+ underground storage tank projects and marquee engagements such as Deepwater Horizon health & safety oversight for 4,000+ personnel.
SEMS goes to market through direct enterprise field sales and a 7-office footprint across Louisiana (Baton Rouge, Shreveport, Mandeville), Texas (Pasadena, Tyler), Mississippi (Jackson), and Tennessee (Memphis, Nashville), supplemented by industry events, a content/news blog, and a 24/7 emergency response line. Distribution is wholly direct — no channel partners or resellers. The company is privately held with no disclosed institutional investors, no parent company, and no public capital markets activity; it has made one disclosed acquisition (Hazclean, Nov 2019) and has expanded its footprint organically through new office openings in 2023 and 2024.
