Spill Clean-up & Remediation

Chemical waste clean up and remediation services are often overlooked parts of maintenance and facilities operations.

If you are renovating or re-purposing a portion of your facility, you may require remediation projects as part of your renovations. If your facility currently or previously has had mercury or large volumes of PCBs, you should take into consideration the impact of past spills when trying to determine a future use for a space.

Items like mercury and PCBs have well established clean-up requirements that may be difficult for you to meet yourself, if you lack that type of training. TRC can help to identify contaminated areas, establish a hazardous waste management plan, and perform a full remediation to regulatory standards. Sometimes this can be as small as a broken mercury device in a laboratory.  Other times it has been a full mercury remediation plan for an old boiler room or transformer vault.


EXAMPLES of projects that require Spill Clean-up and Remediation

Due to the nature of these projects, some details are omitted for privacy reasons. These examples are not meant to give the entire scope of projects and each project is subject to variables. Some types of chemicals addressed with this service can include: PCB's, transformers, chrome contamination, sodium hydroxide, and more. Here are some examples of clean up projects:

Outdoor Mercury Clean-up

PROBLEM: Broken mercury devices in outdoor parking area. Elemental mercury is visible.

SOLUTION: TRC identified contaminated area and cleaned-up to regulatory standards

• Contaminated area vapor concentration measurements were taken throughout cleanup process

• Spill area was identified, and technicians gather affected dirt and sand into 5 gallon DOT-approved container

• Mercury vacuum was used to collect elemental mercury pooled in spill zone and put into 5 gallon DOT-approved container

• Area was screened and mercury levels in asphalt were found to be unacceptably high

• Contaminated asphalt area was removed and packaged for transportation and processing

• Soil below was re screened and found acceptable with non-detectable mercury vapor concentrations

• Elemental mercury and mercury contaminated materials were transported for proper disposal

 Mercury Contamination Clean-up

PROBLEM: Mercury contamination in boiler room (previously unidentified)

SOLUTION: TRC identified contaminated area and cleaned-up to regulatory standards

• Area was monitored due to suspected elemental mercury leaks from boiler room equipment

• Where possible, debris was cleaned up by hand and placed in DOT-approved 55 gallon containers

• Pooled mercury was collected using specialized mercury vacuum and stored in DOT-approved 55 gallon containers

• Mercury containing boiler room equipment was removed and placed into DOT-approved 55 gallon containers

• Waste containers were shipped to end facility for proper disposal

• Surfaces were washed with specialized heavy metal detergent

• Post-Project mercury readings were taken to ensure that mercury contamination was alleviated

Chromic Acid Clean-up

PROBLEM: Small bottle of chromic acid leaked onto a wooden shelf in a storage cabinet. This material was used in a lab, but had not been used for years and it developed a leak.  The acid melted the Styrofoam container holding it and fused the bottle and Styrofoam to the wooden shelf.

SOLUTION: The bottle was separated from the other materials and lab packed for hazardous waste disposal. 

• The wooden shelf, Styrofoam, and some other loose debris all still held chromic acid contamination.

• The loose items were packed into containers.

• The wooden shelf was then removed and packaged with the loose items.

• The floor below the shelf and the underside of the removed shelf were both inspected for contamination.

• A new shelf was installed.

• All waste was shipped as a RCRA hazardous waste.

• All work was performed with ppe include respirators, gloves, and Tyvek suits.
