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.

Licensed asbestos, lead-based paint, mold, radon & water testing across Chicago and the surrounding 100 miles. AIHA-accredited lab. Call 331-462-2711. What is the Asbestos Hazard Emergency Response Act (AHERA) Asbestos Hazard Emergency Response Act (AHERA) was passed by Congress in 1986. AHERA requires public school districts and non-profit private schools to inspect their schools for asbestos containing building material and prepare management plans which recommend the best way to reduce the hazard from any asbestos-containing materials that may be present. Options include repairing damaged asbestos-containing material (such as spraying it with sealants, enclosing it) or removing it. The plans must be developed by accredited management planners and submitted to the State. The school authority must notify parent, teacher and employee organizations of the plans, and then the plans must be implemented. The school district must also perform periodic surveillance of asbestos-containing material every 6 months in its schools. AHERA also requires accreditation of abatement project designers, abatement workers, supervisors, and building inspectors. How do I find out if my child’s school has asbestos in it? The Asbestos-Containing Materials in Schools Rule, pursuant to the Asbestos Hazard Emergency Response Act (AHERA) requires schools to make their asbestos management plans available to the public, including parents, within 5 working days of the request. The asbestos management plan should discuss the location and type of asbestos-containing materials and any preventive measures or response actions taken in your child’s school. You can also contact the school's AHERA Designated Person directly for more information, or if you have specific questions about asbestos in your child's school. The AHERA Designated Person’s name and contact information appears in the management plan. Blog 331-462-2711 Request Quote

If you have any questions or concerns, contact US Environmental Testing for assistance. 1. Maintain Closed-Building Conditions Keep all exterior doors and windows closed for 12 hours prior to the start of the test. You may use exterior doors for normal entry and exit as needed. During the testing period, continue to keep all windows, doors, and other openings to the outside closed. 2. Set and Maintain the Indoor Temperature Set your thermostat to 72°F (±5°F) and switch it to "Auto" mode. Do not alter the testing environment in any way. This includes: Opening windows or doors Changing thermostat or fan settings Operating systems that introduce or remove outside air 3. Avoid Activities That May Affect Test Results Avoid using mechanical systems that draw air out of the building, as they can impact the accuracy of the test. Do not move or tamper with any testing devices once placed. If anything occurs that might violate testing conditions—such as unexpected changes to ventilation, HVAC settings, or open windows—immediately report it to US Environmental Testing. If the test conditions are compromised, we may need to conduct a re-test. 4. Do Not Remove Tamper Evident Seals When we place the radon monitors and start the test, we will install tamper-evident seals on all windows. Do not remove these seals until the test concludes. 5. Receive Your Results The test will conclude 48 hours after the start time. At the time of monitor retrieval, we will provide verbal results.

What is Radon? Radon is a radioactive noble gas formed from the decay of uranium in soil. It infiltrates structures through: Foundation cracks, Sump pits, Utility penetrations, Crawlspaces and slab joints. Once inside, radon accumulates—especially in basements and lower levels. Health Risks: Why is Radon a Serious Threat? Radon is the #1 cause of lung cancer among non-smokers Linked to thousands of U.S. deaths annually Long-term exposure significantly increases risk There are no immediate symptoms, making testing critical What are Radon Action Levels? Radioactivity (and radon gas) results are measured in units of picocuries (pCi) [per liter of air] in the United States versus the International System of Units (SI), the Becquerel (Bq). A picocurie is a unit of radioactivity that is equivalent to one trillionth of a curie. In Perspective, one cure measures the rate of radioactive decay, specifically 3.7 x 10^10 disintegrations per second. What is an Action Level? The EPA recommends fixing homes when radon levels reach 4 pCi/L (150 Bq/m³) or higher. Since no known level of radon exposure is considered safe, the EPA also urges Americans to consider taking action when levels fall between 2 and 4 pCi/L (75–150 Bq/m³). (epa.gov) . Where does Radon come from? Radon is a natural soil gas. It can not be seen, smelled, or tasted; testing is the only reliable way to determine the concentrations of radon gas in any space. The Illinois Department of Emergency Management (IEMA) has established an action level for radon mitigation when levels radon levels exceed 4.0 pCi/L. Licensed professional radon measurements provide accurate results and help homeowners determine whether mitigation is necessary. Testing is particularly important during real estate transactions, basement finishing projects, and routine home safety evaluations. What Is Radon and Why Testing Is Critical Radon is a colorless, odorless radioactive gas that enters buildings through foundation cracks, sump pits, and soil gas pathways. It is the #1 cause of lung cancer among non-smokers, according to the EPA. What Is Considered a Dangerous Radon Level? 0–2.0 pCi/L → Low risk 2.0–3.9 pCi/L → Moderate risk 4.0+ pCi/L → EPA action level (mitigation recommended) When Should You Test for Radon? Buying or selling a home Every 2 years (recommended) After renovations or foundation changes Before finishing a basement If you’ve never tested before Where to get Radon Testing in Private Schools, Public Schools, and Charter Schools: Radon is a naturally-occurring radioactive gas, and exposure to it can cause lung cancer (radon is the second leading cause of lung cancer in the United States). It comes from the natural decay of uranium found in nearly all rock and soils; it typically moves up through the ground to the air above and into an occupancy through cracks and other holes in the foundation. ANSI/AARST MA-MFLB-2023: Protocol For Conducting Measurements Of Radon And Radon Decay Products In Multifamily, School, Commercial And Multi-Use Buildings details protocols when measuring radon concentrations in residential and non-residential occupancies. US ENVIRONMENTAL TESTING has over ten years' experience and hundreds of measurement projects that have included commercial, mixed use, large buildings and campuses, multi-family, and school buildings. If your organization is preparing an air quality study that may include asbestos, lead-based-paint, mold, radon detection, organic compound detection or water system analysis. Contact US Environmental Testing to request a free quote for services. How does radon detection work? Radon testing measures the concentration of radon gas in your home using short-term or long-term detectors that capture the gas or its radioactive decay products. A radon detector is a device that measures the concentration of radon gas in indoor air, typically reporting results in picocuries per liter (pCi/L). Radon is a naturally occurring radioactive gas that seeps into buildings from the ground, and because it’s colorless and odorless, a detector is the only way to know if it’s present. The EPA recommends taking action if your home’s radon level reaches 4 pCi/L or higher. All radon detectors rely on the same basic physics: radon is radioactive, and as it decays, it releases alpha particles. Detectors capture or count these particles to calculate how much radon is in the air. The differences between detector types come down to how they detect those particles and whether they give you a single reading after days or weeks, or continuous updates in real time. Detectors fall into two broad categories: passive and active. Passive detectors have no electronics or power source. They collect a sample over a set period and then get sent to a lab for analysis. Active detectors are electronic monitors that measure radon continuously and display results on a screen or send them to a phone app. Overview of Radon Testing Radon is a radioactive gas that naturally seeps into homes from soil, rock, and water. It is invisible, odorless, and tasteless, making testing the only way to detect its presence and assess potential health risks, such as lung cancer from long-term exposure . US Environmental Testing Services LLC radon detection services in Illinois Initial radon detection Follow-up radon detection Post-mitigation radon detection How does radon enter my home? Radon's primary entry point is through the soil. The amount of radon in the soil depends upon the soil chemistry and varies among houses and may be affected by weather, soil moisture and porosity, home construction, foundation types, and home pressure. Radon levels vary by region but are present in every State. Radon Levels Explained Radioactivity (and radon gas) results are measured in units of picocuries (pCi) [per liter of air] in the United States versus the International System of Units (SI), the Becquerel (Bq). A picocurie is a unit of radioactivity that is equivalent to one trillionth of a curie. In Perspective, one cure measures the rate of radioactive decay, specifically 3.7 x 10^10 disintegrations per second. What is an Action Level?

Since no known level of radon exposure is considered safe, the EPA also urges Americans to consider taking action when levels fall between 2 and 4 pCi/L (75–150 Bq/m³). (epa.gov) What are some entry points of radon into my home? Cracks in floors or walls of the foundation ● Gaps in suspended floors ● Openings around sump pumps and drains ● Wall cavities ● Construction joints ● Gaps around service pipes or wires ● Crawl spaces ● The water supply (Radon can affect bodies of water, specifically ground water) How to find radon mitigation services in Illinois? Radon mitigation professionals may be found on the Illinois Emergency Management Website. Northern Illinois Radon LLC and US Environmental Testing provides testing services for our clients and recommendations to trusted mitigation contractors. Who can do a basic radon home test in Illinois? Northern Illinois Radon, a division of US Environmental Testing (usenvi.com), provides professional radon home testing across Illinois. We place certified short-term or long-term radon detectors in your home, analyze the results in an accredited lab, and give you a clear report so you know whether your family is safe — or whether you need radon mitigation. Will my neighbor's radon levels impact the results or levels in my home? No. Radon levels vary from house to house. The only way to know if you have a radon problem is to conduct a test. "...Your home can have elevated levels of radon while your neighbor's home does not. Testing is the only way to determine if you have a problem. Radon testing is easy and inexpensive, and it could save your life. Thousands of lung cancer deaths could be avoided each year if homes with elevated radon underwent changes to reduce radon pollution." [3] Are homes built with radon resistant materials radon proof? The only way to identify if a dwelling has radon present is to conduct a short- or long- term radon test. All buildings will have radon present. Even homes with integrated Radon Resistant New Construction (RRNC), such as passive new construction pipes (PNPs). When explained further, Radon Resistant New Construction (RRNC), is simply the installation of the radon system pipes without the fan. Making the home "radon system ready," but certainly not resistant to its entry. *If buying from a builder, inquire about the reimbursement options available on new RRNC homes that require the home have a fan installed on the home's radon system to make it meet standards. Many builders offer free or discounted mitigation fan installation on new RRNC homes (if necessary). What is the EPA's Action Level for Radon and What Does it Mean? Radon in air is ubiquitous (existing or being everywhere at the same time). Radon is found in outdoor air and in the indoor air of buildings of all kinds. The EPA recommends homes be fixed if the radon level is 4 pCi/L (picocuries per liter) (150 becquerels per meter cubed (Bq/m3)) or more. Because there is no known safe level of exposure to radon, the EPA also recommends that Americans consider fixing their home for radon levels between 2 pCi/L and 4 pCi/L (75 - 150 Bq/m3) . The average indoor radon concentration for America’s homes is about 1.3 pCi/L (50 Bq/m3). It is upon this national average indoor level that the EPA based its estimate of 21,000 radon-related lung cancers a year. The average concentration of radon in outdoor air is .4 pCi/L (15 Bq/m3)or 1/10th of EPA's 4 pCi/L (150 Bq/m3)action level. Note: Countries worldwide have adopted action levels for radon exposures. Most are similar to the 4 pCi/L (150 Bq/m3) action level recommended in the United States. The action level observed should comply with the guidance of the country, state, or other local jurisdiction of authority where the test is being conducted. For more information, review Protocol for Conducting Measurements of Radon and Radon Decay Products in Multifamily, School, Commercial and Mixed-Use Buildings Section 7.1 Action Level Guidance. (ANSI/AARST MA-MFLB-2023) (source: What is EPA's Action Level for Radon and What Does it Mean? | US EPA) What is considered a high/elevated radon level? There is no safe level of radon exposure. Radon gas is measured in picocuries per liter (pCi/L). The current airborne radon level at which the EPA and IEMA recommend action is 4.0 pCi/L.

Follow-up measurements: a second test performed to confirm levels previously detected; usually performed to verify the results of a home-test kit or to verify another company's test result. Short- and Long- term measurement: Short- term measurements last forty-eight hours to 90-days, while long term measurements tend to last 91 days to one year in duration. Pre- and post- mitigation measurements: a pre-mitigation test may be any test performed prior to mitigation solutions are performed. While post-mitigation testing includes a second test to determine efficacy of the radon mitigation system. The post-mitigation test shall be performed 24 hours to 30-days after the installation and activation of the mitigation system.
