★ DEKON Project Case Study · 2025–2026
CRT Waste Remediation in an Active Warehouse
Yuma, Arizona · 8.31-Acre Site · Adjacent Occupied Tenant Protected Throughout
Project Overview
This project was one of the most complex multi-hazard remediation challenges in DEKON's portfolio: an 8.31-acre property in Yuma, Arizona with a single-story warehouse of approximately 85,692 square feet, within which a non-profit operation had been active since 2001 and remained operational throughout the project.
A previous short-term tenant had leased a 7,000 sq ft portion of the warehouse from 2012 to mid-2013 to operate as a Cathode Ray Tube (CRT) recycler. Improper handling and disposal of CRTs resulted in the abandonment of approximately 3.92 million pounds of CRT glass, partially dismantled electronics, and metal-containing dust contaminated with lead, cadmium, and arsenic. The abandoned waste was stored in cardboard totes covered with plastic sheeting inside the non-climate-controlled tenant space, and on a concrete pad along the exterior northwest corner of the building under heavy tarping — exposed to heat, wind, and rain.
DEKON was engaged to fully remediate the site while protecting the adjacent occupied tenant operation, which remained in active service throughout the project duration.

Key Challenges & DEKON's Solutions
- Active adjacent tenant operating throughout the project duration
- 3.92 million lbs of abandoned CRT glass and electronics — lead, cadmium, arsenic contamination
- Exterior waste pile exposed to desert heat, high winds, and rain on open concrete pad
- Non-climate-controlled warehouse with degraded cardboard containment
- Multi-hazard site requiring simultaneous interior and exterior waste-stream management
- Full RCRA, DOT, and EPA regulatory compliance required throughout
- Precision containment: floor-to-ceiling poly sheeting and chain-link barrier isolating contaminated space from active tenant
- Continuous air monitoring protecting adjacent workers from lead, cadmium, and arsenic dust exposure
- Engineered exterior containment plan addressing heat, wind, and water exposure conditions
- Systematic removal and packaging of all waste into RCRA-compliant containers with full chain-of-custody
- HAZWOPER-certified crew with full PPE protocols; daily safety briefings and hazard assessments
- Coordinated regulatory documentation, waste manifests, and hazardous material transport under DOT 49 CFR
Scope of Work Delivered
- Containment system design and installation — floor-to-ceiling plastic sheeting and chain-link barrier between active tenant and contaminated space
- Continuous air monitoring and dust suppression to protect adjacent workers from Pb, Cd, and As exposure
- Removal, packaging, and labeling of approximately 3.92 million lbs of CRT glass, partially dismantled electronics, and contaminated totes under RCRA standards
- Interior & exterior waste-stream management — cardboard totes, crushed glass, and the exterior concrete pad waste pile under heavy tarping
- DOT-compliant hazardous waste transport coordination — manifests, load counts, and disposal certificates
- Full photographic documentation, chain-of-custody records, and final regulatory compliance reporting
- Zero incidents — all work performed in full compliance with OSHA 29 CFR 1910.120 (HAZWOPER), RCRA, DOT 49 CFR, and EPA requirements
Why This Project Demonstrates DEKON's Capabilities
This site required the convergence of every core DEKON competency: HAZWOPER-level safety management, precision containment engineering, large-scale hazardous waste handling, multi-agency regulatory compliance, and the ability to execute complex operations within an active, occupied facility.
The simultaneous protection of adjacent occupied operations and the complete remediation of 3.92 million pounds of hazardous waste — achieved with zero incidents and high accolades — is a defining demonstration of what DEKON delivers for clients who need it done right.
