Independent environmental consulting
Testing Focused on the Building Conditions and the Evidence
Angstrom Testing Services LLC is led by Paul Scardino, CIH, QEP, LEED AP. The firm provides professional environmental testing and industrial hygiene consulting for clients who need technically appropriate sampling, defensible documentation, and practical interpretation of indoor environmental concerns.
Our work may include a review of the complaint and building history, visual inspection, moisture measurements, direct-reading instruments, air sampling, surface sampling, settled-dust sampling, water sampling, material sampling, laboratory coordination, photographs, field notes, and written reporting.
The scope is developed around the property, suspected source, affected areas, relevant history, project objective, available methods, required reporting limits, applicable licensing, and the decision the client needs to make.
Why independence matters
Independent Testing Without Cleanup Sales Pressure
Angstrom provides inspection, testing, sampling, consulting, laboratory coordination, and reporting. We do not perform mold remediation, asbestos abatement, lead abatement, duct cleaning, restoration, hazardous-material cleanup, plumbing repair, reconstruction, or repair contracting.
Separating assessment from corrective work helps keep the findings centered on the observed conditions, selected sample locations, field measurements, laboratory results, project objective, and appropriate limitations.
Review Angstrom licensing and certifications
01
Objective Scope
Testing is selected for the complaint, building, suspected source, and intended use of the findings.
02
Appropriate Methods
Media, instruments, durations, laboratories, and reporting limits are considered before sampling.
03
Defensible Records
Observations, sample locations, field conditions, methods, and analytical findings are documented.
04
No Cleanup Conflict
Testing findings are not used to generate remediation or abatement contracting revenue.
Professional qualifications
Credentials and Regulatory Licensing
Environmental assessments require more than collecting samples. They require appropriate methods, suitable locations, accurate field documentation, professional interpretation, and a clear explanation of what the findings do and do not establish.
Qualified Environmental Professional
Supports environmental consulting, building investigations, source evaluation, due diligence, and interpretation of environmental data.
LEED Accredited Professional
Provides knowledge related to indoor environmental quality, building materials, ventilation, performance, and occupied-space conditions.
Mold Assessment Licensing
Supports mold inspections, moisture evaluation, sampling plans, remediation protocols, and post-remediation assessment where applicable.
Asbestos Inspection and Air Sampling
Supports inspection, suspect-material sampling, renovation-related assessments, air monitoring, and asbestos documentation.
Lead Risk Assessment
Supports XRF lead paint testing, lead dust wipe sampling, hazard evaluation, clearance testing, and written lead assessment reports.

Building Hazards and Dust
Asbestos, lead paint and lead dust, crystalline silica, mercury vapor, construction dust, regulated-material investigations, exposure monitoring, and post-corrective-work documentation.
Water and Specialized Assessments
Drinking-water testing, potable-water Legionella sampling, building water investigations, and radiofrequency exposure measurements for occupied spaces, rooftops, schools, offices, and residential properties.
Field inspection and documentation
Building Observations, Measurements and Targeted Testing
From concern to written findings
Our Environmental Testing and Reporting Approach
Discuss the Concern
We review the property, complaint, history, affected areas, previous work, occupancy, timing, suspected source, and documentation needs.
Develop the Scope
Inspection activities, instruments, samples, locations, laboratories, reporting limits, and deliverables are selected.
Inspect and Sample
Accessible conditions are evaluated and air, surface, dust, water, material, moisture, or direct-reading measurements are collected.
Analyze the Data
Laboratory and field data are reviewed with the sample locations, comparison samples, building conditions, and technical context.
Report the Findings
Documentation explains what was evaluated, what the results show, relevant limitations, and recommended next steps when warranted.
Important limitation:
Environmental testing can document selected conditions, measurements,
and laboratory findings. It does not diagnose illness or determine
medical causation. Health questions should be discussed with a qualified
healthcare professional or public-health agency.
