Industrial Hygiene Services to GSA National Capital Region
Over 300 individual task orders ranging in cost from $250 to $250,000 while adhering to quality standards, schedules, and budgets.
We are providing Industrial Hygiene (IH) services to the Safety, Environment, and Fire Protection Branch of the GSA National Capital Region (NCR) Public Building Service (PBS) in the nation’s capital as the managing member of a joint venture (TTL Arc Environmental JV, LLC) under contract to perform comprehensive IH services including indoor air quality, asbestos, lead, and mold identification/testing, in all the GSA-owned properties in Washington, D.C. This includes over 250 facilities throughout our nation’s capital and excludes only the living quarters of the White House, the Pentagon, and the Capitol.
Since 2012, TTL Arc (now part of CT Consultants, Inc.) has provided comprehensive services that include but are not limited to consultation, surveys, air monitoring activities, sampling, on-site and laboratory-based analyses, direct read meter assessments and specification review for all potential chemical, physical, biological and environmental hazards.
TTL Arc has completed individual delivery/task orders involving Asbestos Containing Materials (ACM), Lead-Based Paint (LBP), Drinking Water Quality, Indoor Air Quality (IAQ), Radon, and Moisture Conditions/Mold/Bacteria.
As part of our present IH Services contract, TTL Arc has held delivery orders for
- GSA FIA sampling
- Abatement monitoring for asbestos and lead
- Phase I and Phase II ESAs
- Spill Prevention Control & Countermeasure (SPCC) management plan compliance evaluation

For one task order, TTL Arc conducted post-remedial microbial air testing in the U.S. Secret Service (USSS) Firing Range and associated offices, kitchen, restrooms, lockers, and break room spaces in the basement of the William Jefferson Clinton Federal Building (formerly Ariel Rios).
Remodeling activities were in response to a flooding incident. TTL Arc performed pre-clearance visual inspections and then conducted sampling to identify and enumerate viable fungi and bacteria. Corresponding outdoor samples were collected for comparison. We measured the ambient environmental air quality parameters following initial remedial activities and remodeling in the affected areas.
Post-remediation testing was completed, with results indicating that viable mold spores were still present at elevated levels in the office and kitchen areas. TTL Arc informed GSA of the sampling results, and the remodeling contractor conducted additional cleaning in the identified areas. Post-remediation sampling was completed and indicated that viable bacteria and mold spores were below the OSHA-recommended threshold levels for indoor environments. We observed no additional visible microbial growth in the assessed areas, and measurements of air quality parameters were within the acceptable range. No detectable levels of carbon monoxide were identified during the post-remediation sampling.
The TTL Arc team is led by a Certified Industrial Hygienist (CIH), certified by the American Board of Industrial Hygiene, and a Certified Safety Professional (CSP), approved by the Board of Certified Safety Professionals.
TTL Arc has worked on over 300 individual task orders ranging in cost from $250 to $250,000 while adhering to quality standards, schedules, and budgets.
