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.

Licensed asbestos, lead-based paint, mold, radon & water testing across Chicago and the surrounding 100 miles. AIHA-accredited lab. Call 331-462-2711 Indoor Air Quality Testing for Chicagoland Homes Businesses Cleaner indoor air starts with knowing what is in it. US Environmental Testing LLC provides professional indoor air quality testing throughout Chicagoland and communities within approximately 200 miles of Chicago. We help homeowners, property managers, landlords, real estate professionals, and businesses investigate mold, radon, volatile organic compounds, allergens, and other potential indoor air concerns. Indoor pollutants are not always visible or detectable by smell. They may come from moisture, combustion appliances, pets, furnishings, household products, soil gases, or outdoor contaminants entering the building. A professional indoor air quality assessment can help identify possible sources and guide practical next steps. Concerned about the air in your property? Contact US Environmental Testing LLC to schedule an indoor air quality consultation. Indoor Air Quality House Throughout the House Every room can contain different pollutants. Explore the areas below for a quick look at common indoor air quality issues, prevention tips, and signs that professional environmental testing may be appropriate. Living Room: Allergens, Smoke and Combustion Pollutants Living rooms are among the most frequently used spaces in a home. Carpets, upholstered furniture, fireplaces, candles, pets, and tobacco smoke can all affect indoor air quality. Regular cleaning, source control, and proper ventilation can help reduce exposure. Pet dander and hair Pet dander consists of tiny particles of skin shed by animals. Along with pet hair, saliva, and proteins carried on clothing and furniture, it can contribute to allergy and asthma symptoms. Keep pets out of bedrooms when possible. Limit access to upholstered furniture. Vacuum carpets, rugs, and furniture regularly using a HEPA-filter vacuum. Wash pet bedding frequently. Consider professional allergen or particulate testing when symptoms persist without a clear cause. Secondhand smoke Secondhand smoke contains fine particles, gases, and chemicals that can aggravate asthma and increase the risk of respiratory and cardiovascular illness. Children, older adults, and people with existing health conditions may be especially vulnerable. The most effective protection is to keep smoking and vaping entirely outside the home, garage, and vehicle. Opening a window or using an air freshener does not eliminate secondhand smoke pollutants. Carbon monoxide Fireplaces, furnaces, boilers, generators, and leaking chimneys may release carbon monoxide when they malfunction or vent improperly. Carbon monoxide is a colorless, odorless gas that can cause headache, dizziness, nausea, confusion, loss of consciousness, or death. Keep chimney flues open while fireplaces are operating, maintain combustion equipment, and install working carbon monoxide alarms on every level and near sleeping areas. Leave the property and contact emergency services immediately if a carbon monoxide alarm sounds or occupants develop sudden symptoms. Bedroom: Dust Mites and Airborne Allergens Bedrooms often contain fabrics and soft surfaces that collect dust, pet allergens, pollen, and dust-mite debris. These pollutants may contribute to nighttime congestion, coughing, itchy eyes, allergy symptoms, and asthma flare-ups. Dust and dust mites Dust mites commonly live in mattresses, pillows, bedding, carpeting, upholstered furniture, and stuffed toys. They thrive in warm, humid environments. Wash bedding regularly according to the manufacturer's care instructions. Use allergen-resistant mattress and pillow covers. Damp-dust hard surfaces rather than dispersing particles into the air. Vacuum with a HEPA-filter vacuum. Keep indoor relative humidity controlled, ideally around 30% to 50%. Investigate ongoing allergy symptoms that improve when occupants leave the building. US Environmental Testing LLC can help determine whether indoor particulate matter, allergens, moisture, or another environmental condition may be contributing to poor bedroom air quality. Bathroom: Moisture, Mold and Ventilation Bathrooms generate substantial moisture. Without adequate exhaust ventilation, condensation can collect on ceilings, walls, windows, grout, cabinets, and concealed building materials. Mold and excess humidity Mold can grow when moisture and a suitable food source are present. Warning signs may include visible discoloration, a musty odor, peeling paint, damaged drywall, recurring condensation, or symptoms that appear worse in a particular room. Run a bathroom exhaust fan during bathing and afterward. Confirm that the fan vents outdoors rather than into an attic. Repair plumbing leaks promptly. Dry wet surfaces and materials as soon as possible. Clean and maintain grout, caulk, and shower enclosures. Investigate recurring mold instead of repeatedly painting over it. Professional mold testing may be useful when the source is uncertain, growth may be hidden, occupants report persistent symptoms, or documentation is needed for a property transaction or remediation plan. Kitchen: VOCs, Pesticides and Combustion Gases Cooking appliances, cleaning products, pest-control materials, and stored chemicals can introduce gases and particles into kitchen air. Good ventilation and careful product storage are essential. Volatile organic compounds Volatile organic compounds, or VOCs, are gases released by many cleaners, disinfectants, paints, adhesives, air fresheners, solvents, furnishings, and building products. Exposure may cause eye and throat irritation, headache, dizziness, or other symptoms, depending on the compound and concentration. Follow all label and ventilation instructions. Keep chemical containers tightly closed. Never mix cleaning products. Store products away from children and living areas. Choose low-VOC or fragrance-free products when practical. Increase outdoor-air ventilation during painting, cleaning, or renovation. VOC testing can help investigate unexplained odors, chemical exposure concerns, renovation-related symptoms, or suspected off-gassing from new materials. Pesticides Pesticides can irritate the eyes, nose, throat, and lungs. Some products may also pose neurological or other health risks when misused. Prevent pest entry by sealing gaps, removing food and water sources, and using traps or other non-chemical controls when appropriate. When pesticides are necessary, use only products approved for the intended location and follow the label exactly. Gas stoves and carbon monoxide Gas-fired cooking appliances may release carbon monoxide, nitrogen dioxide, and other combustion byproducts, particularly when they are improperly installed, poorly maintained, or used without adequate ventilation. Use an exterior-venting range hood whenever possible. Never use a gas oven or stove to heat the home, and arrange qualified service if flames burn abnormally, soot appears, or occupants experience unexplained symptoms. Basement and Crawl Space: Mold, Radon and Moisture Basements and crawl spaces can influence air throughout a building. Moisture, mold spores, odors, radon, and soil gases may move upward through cracks, wall cavities, utility openings, ductwork, and natural air pressure differences. Basement mold Foundation seepage, plumbing leaks, condensation, flooding, and high humidity can support mold growth on drywall, wood, insulation, carpeting, cardboard, and stored belongings. Correct leaks and drainage problems at their source. Keep gutters and downspouts functioning properly. Use a correctly sized dehumidifier when needed. Maintain relative humidity near 30% to 50%. Remove standing water and begin drying wet materials promptly. Avoid storing cardboard directly on basement floors. Mold inspection and testing can help locate hidden moisture problems and support a targeted remediation strategy. Testing should complement - not replace - a thorough visual and moisture investigation. Radon Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It can enter through foundation cracks, sump pits, floor drains, construction joints, and openings around pipes. Radon cannot be seen, smelled, or tasted. Testing is the only way to determine a building's radon level. Long-term radon exposure increases lung cancer risk, and radon is recognized as a leading cause of lung cancer among people who do not smoke. For existing homes: Test the lowest level that is regularly occupied or suitable for occupancy. Follow closed-building and test-placement instructions carefully. Consider a professional measurement for real estate transactions or when independent documentation is important. If results are 4.0 picocuries per liter (pCi/L) or higher, consult a qualified radon mitigation professional. Consider measures to reduce exposure even when results fall between 2.0 and 4.0 pCi/L. For new construction: Radon-resistant new construction uses common building techniques to limit soil-gas entry and vent radon above the roof. Buyers should ask builders about radon-resistant features, but every new home should still be tested after occupancy - including homes built with a passive radon system. When Should You Schedule Indoor Air Quality Testing? Consider an indoor environmental assessment when: Occupants experience headaches, coughing, congestion, eye irritation, fatigue, or allergy-like symptoms that improve away from the property. A musty, chemical, smoky, or unexplained odor persists. Water damage, flooding, condensation, or plumbing leaks have occurred. Mold is visible or suspected behind walls, under flooring, or above ceilings. A basement or crawl space feels damp. A new building material, furnishing, coating, or cleaning product creates an ongoing odor. A home is being purchased, sold, renovated, or occupied after a prolonged vacancy. Radon has never been tested or previous results are outdated. A landlord, insurer, contractor, or remediation company needs independent environmental data.

Additional Emerging Contaminants: Testing options for other chemical, microbial, inorganic, and organic contaminants based on the water source and project objectives. PFAS, PFCAs, PFSAs & Fluorotelomer Compounds: What Should Be Tested? PFAS contamination is an increasingly important environmental concern for homeowners, commercial property owners, municipalities, industrial facilities, and real estate professionals. PFAS is a large family of manufactured chemicals used in numerous industrial applications and consumer products. Certain PFAS compounds are highly persistent in the environment and may enter groundwater and drinking water supplies. A comprehensive PFAS water testing program may include: Perfluoroalkyl carboxylic acids (PFCAs). Perfluoroalkyl sulfonic acids (PFSAs). Perfluorooctanoic acid (PFOA). Perfluorooctanesulfonic acid (PFOS). Perfluorohexanesulfonic acid (PFHxS). Perfluorononanoic acid (PFNA). Perfluorobutanesulfonic acid (PFBS).
