What White Lake Dock & Dredge, Inc does

White Lake Dock & Dredge, Inc. is a Norton Shores, Michigan–headquartered specialty contractor providing environmental sediment remediation and marine construction services. Its core work is precision environmental dredging of contaminated sediments — most frequently manufactured gas plant (MGP), polychlorinated biphenyl (PCB), and metals-impacted material — using a truck-portable fleet of long-reach excavators (Volvo EC480-class), SENNEBOGGEN material handlers, and hydraulic dredges integrated with RTK-GPS machine control and HYPACK DREDGEPACK guidance. The company augments dredging with eight integrated service lines: hydrographic surveys (multi-beam and single-beam), marine sediment sampling (Vibrocore and piston core to 150-foot depths), subaqueous capping including reactive carbon (GAC/PAC) caps, sediment processing and dewatering with in-barge polymer solidification, shoreline and bank stabilization, marine construction (sheet pile, pile driving, marinas, piers), and habitat/wetland restoration.

The company operates as a division of ENTACT, which its parent describes as the largest remediation contractor to private industry in the United States. Revenue is generated through project-based contracting — competitive bids and direct proposals — with federal agencies (USEPA, USACE), state environmental regulators (NYSDEC, WDNR, EGLE), and large private industrial clients in energy (CMS Energy, Ameren), chemical/manufacturing, and rail (CN). Pricing is contract-specific and not publicly disclosed. Geographic reach extends across the Great Lakes, broader Midwest, Northeast, and Southwest United States, with project execution in Canada. The firm has managed more than 5.5 million cubic yards of sediments across 200+ projects and 200+ acres of subaqueous capping, and reports 25+ years of operational experience with average senior associate tenure of 30+ years.

• Manson Construction: Family-owned marine construction and dredging contractor performing mechanical and hydraulic dredging, pier/wharf construction, and environmental remediation projects. Operates a similar equipment-based, project-bid model to White Lake.
• Environmental Restoration LLC: Environmental remediation contractor performing sediment cleanup, soil remediation, and emergency response. Overlaps with White Lake on sediment remediation bids to federal and private clients.
• Sevenson Environmental Services: Established U.S. environmental remediation contractor with sediment remediation and waterfront cleanup capabilities. Competes with White Lake on EPA, USACE, and private-industry contaminated sediment projects.
• Weeks Marine: Major U.S. marine construction, dredging, and tunneling contractor with a heavy portfolio in capital and maintenance dredging, coastal restoration, and pier/quay construction. Competes for many of the same USACE, port authority, and private waterfront awards.
• Cashman Dredging & Marine Contracting: U.S. marine construction and dredging contractor providing environmental dredging, harbor deepening, and waterfront infrastructure. Highly comparable to White Lake across dredging, marine construction, and shoreline/civil works service lines.

Others

• ENTACT: Parent company of White Lake Dock & Dredge and the largest remediation contractor serving private industry in the U.S. While not a competitor, ENTACT is the closest strategic and operational counterparty that defines White Lake's market positioning and go-to-market reach.

Broad incumbents

• Tetra Tech: Global consulting and engineering firm with a substantial environmental remediation and water-resources practice. Competes in the upstream consulting/design phase of many sediment remediation programs alongside White Lake's execution role.
• Arcadis: Global design, engineering, and environmental services firm with a large remediation practice. Competes on large Superfund and private-industry sediment projects but as part of a much broader portfolio of environmental and consulting services.
• TRC Companies: U.S. engineering, environmental consulting, and construction management firm with sediment remediation and water infrastructure capabilities. Overlaps with White Lake on environmental remediation RFPs, though TRC's scope is far broader.
