MECx

What MECx does

MECX is a Houston-headquartered multi-disciplined environmental engineering, consulting, water treatment, environmental construction, and remediation firm that has operated as a privately held Service-Disabled Veteran-Owned Small Business (SDVOSB) since its February 2002 spin-off from ManTech International's environmental consulting division. The firm serves federal, state, and local government agencies as well as commercial and industrial clients including real estate management firms, corporations, law firms, lending institutions, insurance companies, and industrial facilities, leveraging its CVE-verified SDVOSB status and GSA Schedule access for government contract entry. Operationally MECX runs five integrated service lines (consulting, remediation, engineering, quality/chemistry, and water treatment) with offices in Houston and Chicago supporting project delivery across North and South America.

The remediation practice is built around proprietary chemical oxidation and groundwater treatment technologies refined over 20+ years of laboratory and field development. Core technical differentiators include an empirically derived computer modeling program for site-specific treatment design and reagent dosing; proprietary low-temperature and low-pressure ISCO/ESCO processes; a solvent-enhanced NAPL treatment process using natural citrus or soy-based solvents; in-situ bracing and shoringsystems that enable excavation beneath active buildings to depths of 35 feet with minimal facility disruption; closed-loop enhanced soil vapor extraction (ESVE); and engineered vapor intrusion and groundwater management systems. An in-house treatability laboratory at the Houston headquarters supports site-specific optimization, reducing dependence on external laboratories and enabling cost-effective reagent design.

MECX monetizes via project-based professional services contracts, quoting work per project based on scope, site complexity, and regulatory requirements, with multi-year contract cadences common. Distribution is direct enterprise/government field sales: the firm engages government procurement officers via CCR, PRO-Net, GSA Schedule, and agency-specific contractor databases (holding prime contracts with NASA, U.S. EPA, U.S. Army Corps of Engineers, U.S. Department of Labor, and the Veterans Administration), and pursues commercial clients through RFP response and direct relationship development. Technology and JV channels include the MECX-TAP JV formed in 2019 (with a Michigan EGLE soil remediation win) and preferred supply partnerships with Solvay and NALCO/ECOLAB for oxidants and water treatment chemistry.
