What Decontamination Decommissioning and Environmental Services does

Decontamination Decommissioning and Environmental Services, LLC (DDES) is a private US-based B2B professional services firm founded in 2010 and headquartered in Middleton, Massachusetts, that provides turn-key radiological, chemical, and biological decontamination, decommissioning, and radioactive waste management services. The company serves enterprise clients in three core verticals: pharmaceutical research and development (its founding segment), radionuclide manufacturers, and real estate developers dealing with radium-paint impacted sites. Project work includes single-laboratory moves, full campus decommissioning, and broad-scope radioactive materials license termination under NRC and agreement-state jurisdiction, with examples including a 50,000 sq ft, seven-story radium remediation in Waterbury, CT and a 3,200 cubic yard soils disposal at a former clock manufacturer in Chelsea, MA.

DDES's underlying technology stack centers on MARSSIM-based Final Status Survey methodologies, site-specific RESRAD parameter analysis, GIS-based data capture for site characterization, and a proprietary portable ISOCS gamma spectroscopy unit that enables real-time in-field soil analysis and prescreening of FSS samples. The company has also authored what it describes as the first Radium Cleanup Plan for a Non-Military Radium Site under NRC jurisdiction and operates in compliance with 10 CFR, NUREG-1757, NUREG-1575, ANSI/AIHA Z9.11, Connecticut DEEP, and Massachusetts Radiation Control Program criteria.

DDES makes money through project-based professional services fees on multi-month decontamination and decommissioning engagements, supplemented by radioactive waste handling and disposal coordination and recurring radiation protection support (RSO services, audits, training). Its go-to-market is consultative enterprise field sales, with no public pricing tiers and no third-party intermediation in the disposal chain — DDES positions itself as an "anti-broker" by leveraging direct relationships with the three major radioactive waste disposal companies, a structural arrangement the company says has saved clients millions of dollars in waste costs and is central to its value proposition.

Revenue model

1. Decontamination and Decommissioning Services: Turn-key professional services for radiological, chemical, and biological decontamination and decommissioning projects, including license termination for NRC and agreement states. Revenue is project-based and earned through successful project execution.
2. Radioactive Waste Management and Disposal: Direct waste disposal services connecting clients with disposal sites, handling and packaging of multi-Curie quantities of radioactive wastes. Cost savings achieved by cutting out waste brokers and going direct to disposal sites.
3. Radiation Protection Support Services: Radiation protection plan support, RSO (Radiation Safety Officer) services, audits, and training for clients handling radioactive materials
4. Site Characterization and Remediation: Environmental characterization services including delineation of radiological contamination, site-specific RESRAD parameter analysis, and soils remediation for unrestricted release

Core offering

DDES provides turn-key professional services for the decontamination and decommissioning of facilities impacted with radiological, chemical, and biological hazardous constituents. The company supports radioactive material license termination in NRC and agreement states, handles multi-Curie radioactive waste disposal through direct disposal-site relationships, conducts site characterization and soils remediation using RESRAD parameters and ISOCS gamma spectroscopy, and delivers radiation protection support including RSO services, audits, and training.

Product overview

DDES offers a unified portfolio of turn-key decontamination and decommissioning services for radiological, chemical, and biological hazardous constituents. The core service offering includes: Decontamination & Decommissioning (supporting radioactive material license termination), Site Characterization & Remediation (using RESRAD parameters, GIS, and portable ISOCS gamma spectroscopy), Radioactive Waste Management (handling multi-Curie quantities with direct disposal site connections), and Radiation Protection Support (RSO services, audits, and training). DDES positions itself as an 'anti-broker,' connecting clients directly with disposal sites rather than using waste brokers.

Broad incumbents

• AECOM: AECOM is a large global E&C and environmental services firm with nuclear and environmental remediation practices. It competes for D&D and remediation projects as part of a much broader portfolio, including federal nuclear and environmental work.
• AtkinsRéalis: AtkinsRéalis (formerly SNC-Lavalin) operates a large nuclear and environmental services business covering D&D, site remediation, and regulatory support. It is a broad incumbent offering similar capabilities to DDES as part of a much larger E&C portfolio.
• Jacobs Solutions: Jacobs is a major E&C firm with a significant nuclear and environmental remediation business supporting U.S. Department of Energy and commercial nuclear clients — a broad incumbent with overlapping D&D, characterization, and remediation capabilities.

Direct peers

• EnergySolutions: EnergySolutions is a leading U.S. provider of nuclear services, including decommissioning, radioactive waste management, and site remediation for commercial and government nuclear sites — directly comparable to DDES's D&D, waste management, and license-termination offerings at much larger scale.
• Studsvik: Studsvik is a Swedish-based nuclear services firm providing D&D, waste management, and consulting — a closely comparable peer in technical nuclear services and radioactive waste handling, operating in a different geography but serving similar end markets.
• Perma-Fix Environmental Services: Perma-Fix provides nuclear and mixed waste treatment, disposal, and remediation services, including radioactive waste processing at its own facilities — directly comparable in waste management and site remediation, with overlap in serving nuclear and research-sector clients.
• Veolia Nuclear Solutions: Veolia Nuclear Solutions (through Kurion and other acquired assets) provides nuclear D&D, waste treatment, and site remediation globally, making it a directly comparable peer in nuclear decommissioning and radioactive waste management, though at significantly larger scale.
• Nuvia: Nuvia provides nuclear decommissioning, radiation protection, and waste management services to nuclear, defense, and research sector clients — closely comparable in service mix (D&D, RSO support, waste management) and client base (research, nuclear).

Others

• Mirion Technologies: Mirion Technologies supplies radiation detection, measurement, and monitoring instrumentation used in nuclear, D&D, and radiation protection applications. It is an enabling technology provider adjacent to DDES's radiation protection and gamma spectroscopy capabilities rather than a direct competitor.

Emerging players

• HPS (Health Physics Society) member firms - Radiation Safety Associates: Radiation Safety Associates and similar small health physics and radiation safety consulting firms offer RSO support, audits, and training that overlap with DDES's Radiation Protection Support service line, though typically without the turn-key D&D and waste disposal capabilities.
