Project Details
Challenge
Exceeding Wastewater Mercury Limits
In response to a notice of violation for exceeding mercury limits in wastewater, 3D Enviro undertook an urgent environmental assessment and remediation at an NIH-leased research facility. This case study highlights the complexities of tracing and mitigating mercury sources in laboratory environments.
Approach
Comprehensive Mercury Source Identification
3D Enviro’s response included detailed investigations to pinpoint the mercury sources:
Testing and Analysis: Employed the Ohio Lumex Mercury Analyzer to assess mercury levels in various sinks and drains within the facility.
Targeted Sites: Focus was placed on laboratory sinks, janitor sinks, and other potential discharge points like floor drains and fume hood cup sinks.
Findings and Immediate Actions
Elevated Mercury Levels: Six laboratory sinks and one janitor sink showed significantly higher mercury levels compared to the ambient background.
Further Investigation: Continued testing of downstream drainpipes from the affected sinks revealed persistent high mercury levels.
Remediation Efforts
Sink and Drainpipe Treatment: Removed p-traps of affected sinks and applied a mercury vapor suppressant followed by hydro-jetting in the drainpipes.
Wastewater Management: Isolated the building’s wastewater flow into a neutralization tank to prevent further violations during the cleanup process.
Hazardous Waste Disposal: Safely disposed of the neutralization tank’s contents as hazardous waste.
Project Results
Results
Effective Mercury Reduction
Successful Clearance Levels: All but one sink drainpipe tested below the post-decontamination clearance level of 1,000 ng/m3.
Specific Case Management: One problematic sink in a second-floor lab was further investigated, leading to the discovery and remediation of a highly contaminated section of the drainpipe.
Conclusion
Ensuring Compliance and Safety
This project addressed the immediate compliance issues and underscored the importance of rigorous environmental safety practices in research facilities. 3D Enviro’s effective management and technical approach resulted in a quick resolution of the violation, demonstrating our commitment to environmental stewardship and public health.
