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.

US Environmental Testing LLC helps coordinate professional water sampling and laboratory analysis through appropriately qualified and certified laboratories. Contact us to discuss your location, water source, and testing requirements. Can you test my drinking water for PFAS and forever chemicals? Yes. We coordinate PFAS drinking water testing for specified compounds, including PFOA, PFOS, PFCAs, PFSAs, and applicable fluorotelomer compounds such as 6:2 FTS and 8:2 FTS. How do I test my water for lead? Lead testing requires collecting a water sample using the appropriate sampling protocol and submitting it to a qualified laboratory. Sampling procedures depend on whether you need a first-draw, flushed, or other type of sample. Does US Environmental Testing perform Legionella testing? Yes. We coordinate environmental water sampling and laboratory analysis for Legionella bacteria in commercial, residential, healthcare, and institutional water systems. Can PFAS be detected in water that looks clean? Yes. PFAS generally cannot be identified by appearance, taste, or smell. Laboratory analysis using appropriate validated analytical methods is necessary to determine whether these compounds are present. What is the difference between PFCA and PFSA? PFCAs are perfluoroalkyl carboxylic acids, while PFSAs are perfluoroalkyl sulfonic acids. Both are important chemical subclasses within the broader PFAS family. What are 6:2 FTS and 8:2 FTS? These are fluorotelomer sulfonic acid compounds associated with PFAS chemistry. They may be included in specialized environmental testing panels depending on the laboratory method and project requirements. Can I test well water for PFAS, lead, and bacteria? Yes. Private well testing can be designed to evaluate multiple contaminants, including PFAS, lead, and microbial indicators. The appropriate test panel depends on the well construction, surrounding land use, and potential contamination sources. How long does water testing take? Turnaround times vary depending on the contaminant, laboratory method, sample preparation, and laboratory workload. Estimated reporting times can be provided when the testing scope is established. Why Choose US Environmental Testing LLC? US Environmental Testing LLC brings more than 10 years of environmental testing and building science experience to residential, commercial, industrial, and institutional projects.

Mold Risk Assessment Environmental Compliance, Consulting, and Risk Assessment Mold is a type of fungus that grows in damp environments. It can cause a variety of health issues, including respiratory problems, allergies, and infections. Not all fungal spores are harmful to our health. The absence or presence of fungal spores may only be verified by sampling and analysis by a licensed technician and laboratory. Fungal spore verification may only be confirmed with the assistance of a microscope. Identification and classification of fungal spores may not be performed by sight. If you suspect that you have mold in your home or business, it's important to get it tested as soon as possible. At US Environmental Testing , we offer all-inclusive fungal spore sampling services to identify source and concentration of fungal spored in the sample site. With the result data set, a plan of action may be derived and used for: 1. General Inspection: property discovery purposes 2. Insurance Investigations: Storm water or water pipe rupture, causing water infiltration. 3. Real Estate transaction inspection. 4. Remediation planning and Post-remediation Valuation (PRV). 4. Litigation investigation / documentation 5. OSHA Investigations: OSHA 300 (3) (6) injuries/illness claim investigation. Upon conclusion of site assessment, US Environmental Testing will create a remedial plan of action to address any potential safety concerns on your site. Aiming to ensure that your space is safe and healthy. Mold in Real Estate 1. The USEPA has reported that home air can have 100 times more chemicals inside than outside. 2. The USEPA has also reported that adults and kids now spend most of their time indoors (90%). 3. The CDC has reported that 20+ million adults have asthma, and the National Asthma Survey has reported that asthma is the most prevalent chronic disease among children. These numbers continue to increase annually, suggesting that the indoor environment plays a contributing role in this trend. 4. Mold growth can be present within the home and be hidden behind walls or underneath carpeting or flooring. 5. The use of Formaldehyde is prevalent in certain building materials and the concentration of this known cancer-causing agent can be many times the safe level. WHAT TO DO ABOUT MOLD? FOUR TYPES OF MOLD ASSESSMENTS 1 General Inspection - Business - Day Care Centers - Home - Office - Schools - Remediation & Post Remediation Valuation 2 Insurance Investigation - Water Infiltration Claims and suspected "mold" presence. - Verifying absence / presence of fungal spores and identifying the spores on site, after water infiltration. 3 Real Estate Inspection - Mold Assessments for real estate transactions - Landlords testing dwellings to assure tenants the property is free of mold - Buyers/Sellers conducting investigative mold assessments of dwellings. 4 Litigation & OSHA 300(3), 300(6) Investigations - Indoor air quality (IAQ) assessments for OSHA 300(3), 300(6) claims for injury/illness respiratory conditions. - Health & Sensitivity to fungal spores, or to Organic Compounds. - A professional Air Quality Assessment by US Environmental Testing will identify the IAQ levels and an Organic Compound Test may be performed to compose a detailed legend of the particles in your environment. How are fungal spores identified? 1. Metered air samples are captured from the sample site. 2. Direct samples may be collected to analyze against air samples. 3. Infrared Thermography technology is used to isolate potential moisture rich substrates in the dwelling which are then further analyzed by moisture meters and investigated further by the inspector.
