Overview
Asbestos abatement monitoring, lead abatement monitoring, and water quality testing: all on one active construction site
When a general contractor needed a qualified asbestos and lead abatement monitoring contractor for a renovation at a federal facility in Boise, Idaho, they called A-Tech Consulting. Our environmental monitoring services covered asbestos abatement monitoring, lead abatement monitoring, potable water quality testing, and post-removal verification, all within an occupied facility undergoing active construction.
This project is a strong example of A-Tech’s ability to mobilize across state lines and deliver. Our team maintained close communication with the contractor’s on-site team throughout and achieved clean clearance results across every service line. Here’s a full breakdown of what the work involved.
Challenge, success & what stood out
Three things that defined how this project came together.
|
Challenge Bidding the project site unseenWithout the ability to walk the site prior to award, our team had to validate the accuracy of the existing assessment report and mobilize based on reported conditions, a challenge that required careful planning and experienced judgment from the outset. |
Success Lab coordination kept the project on scheduleBy leveraging our network of accredited laboratories, we were able to ensure samples were analyzed quickly and results turned around without delay, a critical factor in keeping an active construction timeline moving. |
What stood out Conditions had changed since the original surveyMaterials discovered under flooring systems, within walls, and above ceilings during the project were not previously assessed. A-Tech sampled all newly discovered materials with expedited laboratory analysis to ensure the project stayed on schedule. |
Lead abatement monitoring
Lead abatement monitoring across nine occupied rooms
Our lead abatement monitoring services included full-time, on-site oversight across nine areas of the facility, covering mail processing, storage, locker rooms, and office spaces. Lead-containing white plaster walls were removed from two areas, totaling 450 SF, under our continuous monitoring.
Fourteen lead wipe samples were collected and submitted under chain-of-custody to an NLLAP/ELLAP-accredited laboratory.
Notably, the EPA’s updated dust-lead action levels took effect on January 12, mid-project. Our team identified the regulatory change immediately and applied the new 5 μg/ft² standard to all subsequent samples without disruption to the project schedule. Every post-clearance sample passed.
Asbestos abatement monitoring
Two-phase asbestos abatement monitoring: over 2,000 SF of asbestos-containing material removed
Our asbestos abatement monitoring services covered two sequential phases across six areas of the facility, with 212 PCM air samples collected throughout. Throughout both phases, we conducted perimeter and ambient air monitoring to verify that fiber control methods were protecting building occupants, followed by post-abatement clearance air sampling using Phase Contrast Microscopy (PCM), the industry-standard method for asbestos clearance testing.
A notable challenge on this project was that material conditions had changed since the original survey. Additional asbestos-containing materials were discovered under flooring systems, within walls, and above ceiling systems during active abatement. A-Tech coordinated expedited sampling and analysis of all newly discovered materials through our laboratory network, keeping the project on schedule without expanding the timeline.
Phase 1: Look Out Gallery & Breakout area
- • Materials removed: asbestos-containing plaster, concrete, resilient flooring with mastic, ceiling tile, and cove base
- • Over 800 SF of ACM abated across two areas
- • Clearance air sampling conducted inside containment following final visual inspection
✓ All PCM clearance samples below 0.01 f/cc
Phase 2: Work areas, service center, and supply rooms
- • Over 650 SF of asbestos-containing vinyl tile and mastic in one area alone
- • Additional concrete masonry unit (CMU), cove base, and ceiling tile across three areas
- • Over 1,000 SF of ACM removed in this phase
✓ All PCM clearance samples below 0.01 f/cc
Water quality assessment
Potable water sampling and Legionella testing during active renovation
At the time of the Limited Water Sampling, sampling locations were limited due to capped water lines to typical potable water locations (e.g., drinking fountains). Selected sampling locations were in collaboration with the client’s on-site representative.
During the Limited Water Sampling, four (4) water samples were collected from two (2) locations. Water samples were analyzed for the following client-selected parameters: pH; anions (Nitrate, Nitrite, Fluoride); hardness; metals (Mercury, Copper, Barium, Selenium, Lead, Chromium, Cadmium, and Arsenic); and Legionella (L. pneumophila)
What made this project work
Out-of-region mobilization requires preparation and the right environmental monitoring contractor
Choosing an environmental monitoring contractor for a multi-discipline project means more than checking license boxes. It means finding a team that can coordinate across lead, asbestos, and water quality services without losing the thread, especially when site conditions differ from what was originally reported and the regulatory landscape shifts mid-project, as it did here when new EPA dust-lead action levels took effect on January 12, 2026.
On this project, our team bid and mobilized without the ability to walk the site in advance. When we arrived and found that previously assessed materials had changed, with additional ACM discovered under floors, inside walls, and above ceilings. We responded immediately. Through our established laboratory network, we turned around expedited results on all newly discovered materials and kept the project moving without extending the timeline.
Communication with the contractor’s team was continuous throughout. Sample scheduling was coordinated around the abatement timeline. Reporting was delivered promptly after each clearance phase. For clients managing active construction timelines, delays in environmental clearance are costly, which is why our team prioritizes responsiveness at every stage of asbestos and lead abatement project monitoring.
Results summary
Every sample collected on this project came back clean.
Across asbestos abatement monitoring, lead abatement monitoring, and potable water quality testing, all clearance criteria were met and all regulatory thresholds were satisfied. The facility was cleared for reoccupation and continued renovation on schedule, with zero failed samples across any discipline.
Frequently asked questions
Questions about asbestos and lead abatement monitoring
What does asbestos abatement monitoring mean?
The consultant performs independent, third-party oversight during the removal of asbestos-containing materials (ACM). This includes conducting perimeter and ambient air sampling during abatement to verify engineering controls are working, performing final visual inspections, and collecting post-abatement clearance air samples using Phase Contrast Microscopy (PCM). The consultant works separately from the abatement contractor to ensure regulatory compliance and protect building occupants.
What is post-lead removal verification, and when is it required?
Post-lead removal verification is the process of confirming that lead-containing materials have been successfully removed and that remaining surface lead levels fall below EPA clearance thresholds. It typically involves a visual inspection of the work area followed by dust wipe sampling. As of January 12, 2026, the EPA’s new dust-lead action levels set the clearance standard at 5 μg/ft² for interior floors. Verification is required before a space can be re-occupied or renovated further.
Do you provide asbestos and lead monitoring services outside California?
Yes. While A-Tech Consulting is headquartered in California and primarily serves the western United States, we regularly mobilize for projects in other states, including Idaho, as demonstrated by this project in Boise. If your project requires qualified asbestos abatement monitoring, lead abatement monitoring, or environmental consulting services and you are outside our home region, contact us to discuss mobilization options.
Why is Legionella testing recommended during building construction or renovation?
Construction and renovation activities can disrupt building water systems, including capping lines, changing flow patterns, or creating stagnant water conditions that favor Legionella growth. Testing for Legionella pneumophila during active construction helps identify risk early, before systems are fully restored and occupants return. A-Tech conducts potable water sampling and Legionella testing as part of comprehensive environmental monitoring services for construction and renovation projects.
