Midwest Environmental Consulting Services

What Midwest Environmental Consulting Services does

Midwest Environmental Consulting Services, Inc. (MEC) is a privately held, Illinois-based environmental consulting firm founded in 1994 by Blake G. Mellecker. Originally launched as a single-service asbestos survey business, the company has expanded into a full-service environmental compliance consultancy with four Illinois offices (Yorkville headquarters, plus Chicago, Peoria, and Rockford) and active service coverage spanning Illinois, Indiana, and Wisconsin.

MEC delivers a portfolio of nine practice areas including asbestos inspection and AHERA surveys, lead testing using XRF analyzer technology, mold assessment and remediation oversight, indoor air quality studies, industrial hygiene and OSHA exposure monitoring, safety training programs, environmental audits, Phase I/II Environmental Site Assessments to ASTM E1527-21 standards, and environmental permitting and compliance (NPDES, CAAPP, FESOP, Tier II). The firm employs IDPH-licensed inspectors and risk assessors, engineers, geologists, and project managers, and aggregates over 200 years of combined industry experience across its team. Notable execution includes the Macy's on State Street renovation in Chicago, where MEC managed asbestos, lead, silica, and heavy metals assessment across 75,360 man-hours in partnership with Kinsale Consulting Group.

The company generates revenue through project-based professional services engagements priced by scope, facility size, and required testing. Distribution is sales-led via inbound quote requests, on-site consultations, and customized proposals, supported by SEO-optimized service area pages, content marketing, and a direct sales representative team. Customers span healthcare, K-12 and higher education, construction and demolition, public services, industrial manufacturing, and commercial real estate. In 2025, the City of Kankakee ECDA named MEC Contractor of the Year.
