US Environmental Testing LLC — Professional Environmental Testing. Reliable Information. Informed Decisions. Radon Testing, Radon Detection & Radon Mitigation Planning Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It can enter buildings through foundation cracks, floor penetrations, sump pits, crawlspaces, and other openings. Radon is colorless, odorless, and cannot be detected without proper testing. US Environmental Testing provides professional radon testing and detection services for residential, commercial, multifamily, institutional, and government properties. Our radon services include: Licensed, Professional residential radon testing Commercial building radon testing. Short-term and long-term radon measurements.

Professional Asbestos Inspections & AHERA Asbestos TestingAsbestos was widely used in building materials because of its heat resistance, durability, and insulating properties. Buildings constructed before the 1980s may contain asbestos in insulation, floor tiles, ceiling materials, roofing, pipe insulation, plaster, joint compounds, and other building components.However, asbestos-containing materials may also be present in newer buildings.Disturbing asbestos-containing materials during remodeling, demolition, renovation, or maintenance can release microscopic fibers into the air.US Environmental Testing provides asbestos inspection, building material sampling, and laboratory testing services to help identify asbestos-containing materials before they become an exposure concern.Our asbestos services include:- Residential asbestos inspections.- Commercial asbestos building inspections.- Pre-renovation asbestos inspections.- Pre-demolition asbestos surveys.- Asbestos building material sampling.- Asbestos-containing material identification.- Vermiculite insulation asbestos testing.- Popcorn ceiling asbestos testing.- Vinyl floor tile and mastic asbestos testing.- Drywall and joint compound asbestos testing.- Pipe and mechanical insulation sampling.- Roofing and exterior material asbestos testing.- Laboratory asbestos analysis.- AHERA asbestos inspections and school-related assessment support.- Asbestos inspection documentation and reporting.### AHERA Asbestos Inspections for SchoolsThe Asbestos Hazard Emergency Response Act (AHERA) establishes federal requirements concerning asbestos management in applicable public and nonprofit private schools.AHERA-related services may include inspections, identification of asbestos-containing building materials, management plan support, periodic surveillance, and documentation.AHERA inspections must be performed by appropriately accredited personnel. US Environmental Testing can assist with applicable inspection, sampling, and testing needs within the scope of its personnel qualifications.### Why Test Before Renovation or Demolition?A visual inspection cannot reliably determine whether a material contains asbestos. Laboratory analysis of appropriately collected samples is necessary to identify asbestos in suspect materials.Testing before disturbing building materials can help property owners, contractors, schools, and facility managers make informed decisions about renovation, demolition, maintenance, and occupant protection.**Searching for asbestos testing near me, asbestos inspection in Chicago, AHERA asbestos testing, or an asbestos building inspection? Contact US Environmental Testing for professional assistance.**## 3. Lead-Based Paint Inspections & Lead TestingLead-based paint remains an important environmental health concern in older residential and commercial buildings. Properties constructed before 1978 may contain lead-based paint, particularly on windows, doors, trim, siding, painted surfaces, and friction or impact areas.Deteriorating paint, renovation activities, and contaminated household dust can create potential exposure pathways.US Environmental Testing provides lead-based paint inspection, sampling, testing, and environmental assessment services for property owners, real estate professionals, landlords, schools, childcare facilities, and commercial building operators.Our lead services include:- Lead-based paint inspections.- Lead paint testing.- Lead paint sampling and laboratory analysis.- Lead risk assessments.- XRF lead paint inspection, where appropriately equipped and qualified.- Lead dust wipe sampling.- Lead-contaminated soil sampling.- Lead hazard identification.- Lead inspection support for real estate transactions.- Lead testing for rental properties.- Lead testing for schools and daycare facilities.- Lead testing for renovation and remodeling projects.- Lead documentation and environmental reporting.### Lead Paint Inspections for Real Estate & Property OwnersBuying, selling, renovating, or managing an older property? A professional lead-based paint inspection can help identify potential lead hazards before they become a problem.Lead inspections and risk assessments are not interchangeable. An inspection identifies the presence of lead-based paint, while a risk assessment evaluates lead hazards and potential exposure pathways.Where federal, state, or local regulations require certified personnel, the appropriate credentials and inspection procedures must be used.### Lead Testing for Schools & Daycare FacilitiesChildcare centers, schools, and facilities serving young children have particular reasons to evaluate potential lead hazards. US Environmental Testing supports lead-based paint and environmental sampling needs for applicable institutional properties.## 4. Professional Mold Inspections & Indoor Air Quality AssessmentsMold can develop when moisture enters a building through plumbing leaks, roof failures, flooding, condensation, foundation seepage, HVAC problems, or elevated indoor humidity.Mold growth can occur behind walls, beneath flooring, inside ceilings, within HVAC systems, and in other areas that may not be immediately visible.US Environmental Testing provides mold inspection, indoor environmental assessments, moisture investigations, and mold sampling services for residential, commercial, and institutional buildings.Our mold services include:- Residential mold inspections.- Commercial mold inspections.- Indoor mold assessments.- Mold air sampling.- Surface mold sampling.- Bulk material sampling.- Moisture intrusion investigations.- Water damage assessments.- Post-remediation verification (where appropriate).- Indoor air quality assessments.- HVAC and building-related mold investigations.- Indoor environmental condition evaluations.- Mold laboratory analysis.### When Should You Schedule a Mold Inspection?Consider a professional mold assessment when you notice:- Musty or persistent odors.- Visible mold growth.- Previous flooding or water damage.- Repeated plumbing leaks.- Roof or foundation water intrusion.- Elevated indoor humidity.- Condensation around windows or HVAC equipment.- Suspected mold behind drywall or flooring.- Occupant concerns following water damage.A mold inspection should evaluate the building's moisture conditions and potential sources of water intrusion, not simply identify visible growth.There is no single universally accepted federal indoor mold concentration limit that establishes whether a building is safe. Sampling results must be interpreted in context with building conditions, moisture sources, and the inspection findings.## 5. Certified Drinking Water Testing & Water Quality AnalysisDrinking water quality is an important consideration for homeowners, businesses, schools, healthcare facilities, childcare centers, property managers, and government agencies.Water can contain contaminants that cannot be identified by appearance, taste, or smell. Proper sampling and laboratory analysis help determine whether water meets applicable health-based or regulatory criteria.US Environmental Testing coordinates professional drinking water sampling and laboratory testing for a variety of environmental contaminants.Our water testing services include:- Certified drinking water testing through appropriately certified laboratories.- Residential well water testing.- Commercial drinking water testing.- Lead in drinking water testing.- PFAS drinking water testing.- PFOA and PFOS testing.- PFHxS and other PFAS compounds.- Perfluorinated carboxylic acids (PFCAs).- Perfluorinated sulfonic acids (PFSAs).- 4:2, 6:2, and 8:2 fluorotelomer sulfonates (FTSAs).- Legionella water testing.- Bacterial water quality testing.- Coliform and E. coli testing.- Water quality investigations.- Institutional and facility water sampling.### PFAS, PFOA & PFOS Drinking Water TestingPer- and polyfluoroalkyl substances (PFAS) are a large group of manufactured chemicals historically used in numerous industrial and consumer applications.Certain PFAS compounds have been detected in drinking water and environmental samples throughout the United States.Our PFAS-related testing programs can address compounds including:- PFOA — Perfluorooctanoic acid.- PFOS — Perfluorooctane sulfonic acid.- PFHxS — Perfluorohexane sulfonic acid.- Other PFCAs and PFSAs.- Selected fluorotelomer sulfonates, including 4:2 FTSA, 6:2 FTSA, and 8:2 FTSA.Depending on the sample matrix and analytical objectives, applicable analytical methods may include EPA Method 533, EPA Method 537.1, or EPA Method 1633.Proper PFAS sampling is especially important because cross-contamination can compromise results. Appropriate PFAS-free containers, sampling materials, field blanks, chain-of-custody documentation, and laboratory-specific sampling instructions should be followed.### Lead in Drinking WaterLead can enter drinking water through plumbing materials, solder, fixtures, and service lines. Schools, daycare centers, older buildings, and properties with aging plumbing may benefit from drinking water lead assessments.US Environmental Testing supports lead-in-water sampling and laboratory analysis to help clients evaluate potential contamination.### Legionella Water TestingLegionella bacteria can grow in building water systems under certain conditions. Cooling towers, hot water systems, plumbing distribution networks, and other building water systems may provide conditions that support bacterial growth.Legionella testing can support water management programs, facility investigations, and ongoing monitoring efforts.## 6. Environmental Testing for Schools, Daycare Centers, Government & Commercial PropertiesUS Environmental Testing provides environmental inspection and testing support for properties where environmental conditions, occupant protection, and regulatory documentation are important.Our clients and markets include:- Residential homeowners.- Homebuyers and sellers.- Realtors and real estate brokerages.- Property management companies.- Commercial real estate investors.- Multifamily housing operators.- Schools and universities.- Daycare centers and childcare facilities.- DCFS-regulated childcare facilities.- Healthcare and medical facilities.- Dental offices.- Industrial and manufacturing facilities.- Government agencies.- Municipalities and public buildings.- Contractors and construction companies.- Renovation and demolition contractors.- Military and federal procurement projects.We understand that each property and project has different environmental testing requirements.
