Licensed asbestos, lead-based paint, mold, radon & water testing across Chicago and the surrounding 100 miles. AIHA-accredited lab. Call 630-915-9434. Asbestos is classified into six types, divided into two main groups: serpentine (chrysotile) and amphibole (crocidolite, amosite, tremolite, anthophyllite, actinolite). Classification and Characteristics Serpentine Asbestos Chrysotile (white asbestos): The only member of the serpentine group, chrysotile fibers are curly, flexible, and can be woven into fabrics. It was the most widely used type, accounting for 90–95% of asbestos in buildings and products. Common applications included roofing sheets, ceiling panels, wall plaster, brake linings, pipe insulation, and gaskets. Chrysotile is considered less hazardous than amphibole types but is still a proven carcinogen, capable of causing mesothelioma, lung cancer, and asbestosis The Mesothelioma Center The Mesothelioma Center +2 . Amphibole Asbestos Crocidolite (blue asbestos): Fibers are fine, straight, and needle-like, making them highly hazardous. Historically used in insulation, early gas masks, and even cigarette filters, crocidolite is strongly associated with mesothelioma The Mesothelioma Center The Mesothelioma Center +2 . Amosite (brown asbestos): Fibers are straight and brittle, commonly used in thermal insulation, ceiling tiles, and fireproofing materials. It is also linked to serious respiratory diseases The Mesothelioma Center The Mesothelioma Center +2 . Tremolite, Anthophyllite, Actinolite: Less commonly used industrially, these amphibole types can still be found in insulation, construction materials, and some consumer products. They have fibrous, elongated crystals and are capable of causing cancer and autoimmune conditions The Mesothelioma Center The Mesothelioma Center +1 . Health Risks All types of asbestos are hazardous. Inhaled fibers can become lodged in the lungs, causing irritation and potentially leading to mesothelioma, lung cancer, and asbestosis. Amphibole fibers are generally more dangerous due to their shape and durability, but even minimal exposure to chrysotile is considered unsafe The Mesothelioma Center The Mesothelioma Center +2 . Summary Serpentine group: Chrysotile (white asbestos) – flexible, curly fibers, widely used. Amphibole group: Crocidolite (blue), Amosite (brown), Tremolite, Anthophyllite, Actinolite – straight, needle-like fibers, more hazardous. Understanding these types is crucial for occupational safety, building management, and asbestos abatement, as professional assessment is required to identify and safely handle asbestos-containing materials amg.org.uk amg.org.uk +1 . https://www.bing.com/search?q=types%20of%20asbestos&qs=n&form=QBRE&sp=-1&ghc=1&lq=0&pq=types%20of%20asbestos&sc=12-17&sk=&cvid=572905FF7CD3431BAE492DF06DF3024E

Clean Water is Essential The earth's water supply we rely upon for daily tasks including consumption, has a number of exposures to contaminants that may require analysis to determine the safety for further use. Some of the risks that water may be exposed to include Coliform and E. Coli, Lead, Legionella, Nanoparticles, Per- and Polyfluoroalkyl substances (PFAS) "forever chemicals", fungal spores, Radon, Petroleum-based particles, and it has become our responsibility to sample and identify the concentrations of these contaminants in our water sources before consumption. "Research has raised concerns about the potential health effects of PFAS exposure. Some studies suggest that high levels of PFAS in the body may be linked to various health issues, including: Hormonal disruptions Increased cholesterol levels Immune system effects Certain cancers** PFAS are persistent in the environment, meaning they do not break down easily and can accumulate in the soil, water, and living organisms. This persistence has led to widespread contamination, with detectable levels of PFAS found in drinking water, fish, and even human blood samples across the globe.

FAQ - ACM Asbestos Containing Materials (ACM) Asbestos Testing vs Asbestos Inspection Understanding the Difference Before You Renovate, Demolish, or Purchase a Property How much does asbestos testing cost in Chicago? Costs vary based on the number of samples required, property size, and project scope. Most residential testing projects can be completed quickly with laboratory analysis provided afterward. Can I remove asbestos myself? Illinois regulations may restrict asbestos removal activities. Testing should always be completed before disturbing suspect materials. How long does asbestos testing take? Field sampling is often completed within a few hours. Laboratory turnaround depends on the analysis requested. What materials commonly contain asbestos? Pipe insulation, floor tiles, ceiling texture, roofing materials, siding, drywall compounds, and thermal insulation are common asbestos-containing materials. Schedule an Asbestos Inspection Today US Environmental Testing provides responsive asbestos testing services across the Chicago metropolitan area. Contact us to schedule a certified asbestos inspection and laboratory analysis. Asbestos Inspection - Home Renovation - Illinois I'm worried about asbestos in an older home I'm renovating in Illinois - what should I do? If your home was built before 1980 — and especially if it was built before 1978 — there is a very real chance that asbestos-containing materials (ACMs) are present somewhere in the structure. Before you swing a single hammer or hire a contractor to begin demolition, you need a licensed asbestos building inspection from a certified IDPH asbestos inspector. This isn't just the smart thing to do — in Illinois, disturbing ACMs without prior inspection may violate state and federal regulations. Critical Warning: Do not sand, drill, cut, or demolish any material in a pre-1980 home before testing. Disturbing asbestos-containing materials releases microscopic fibers that are invisible to the naked eye and cause mesothelioma and lung cancer. Once airborne, asbestos fibers can contaminate an entire home and require costly decontamination.

Lead-based paint testing FAQ - LBP How will I know if there is lead-based-paint used in my house and if there is need for action? The older your home, the more likely it contains lead-based paint. For example, 87% of homes built before 1940 have some lead-based paint, while 24% of homes built between 1960 and 1978 have some lead-based paint. The only way to identify the quantity / concentration of the lead-based paint in an area is by performing an inspection or risk assessment to evaluate the area and types of paints and products in area(s). Wh at year was lead paint banned? Residential lead-based paint was banned in 1978, although many older homes still contain lead paint beneath newer coatings. Is lead paint dangerous if undisturbed? Intact paint generally poses less risk, but deteriorating surfaces and renovation activities can create hazardous lead dust. How do you test for lead paint?

Protecting your family from radon starts with one phone call. Northern Illinois Radon LLC — part of US Environmental Testing — is your local IEMA-licensed radon measurement professional serving the greater Chicago area and all of Northern Illinois. We have been helping Illinois families breathe safely since 2015. Illinois radon facts: Radon is the #1 cause of lung cancer in non-smokers and the #2 cause of all lung cancer in the United States. Illinois is a high-radon state — and Northern Illinois counties consistently show elevated levels above the EPA action level. A Harvard School of Public Health study found nearly 25% of the U.S. population may be exposed to dangerous radon concentrations. The only way to know if your home is safe is to test. Radon is colorless, odorless, and tasteless — you cannot detect it without a professional test. It enters your home through small cracks and openings in the foundation as a natural radioactive soil gas. When inhaled, its decay products damage the lining of the lungs over time through alpha and beta radiation exposure. 1. We schedule a convenient appointment — including evenings and weekends throughout Chicagoland. 2. An IEMA-licensed radon measurement professional places professional-grade continuous electronic monitors — not mail-in charcoal kits — in your home's lowest livable area. 3. After the EPA/IEMA-required closed-building measurement period, we retrieve the monitors and generate your certified radon test report. 4. If levels are at or above the EPA action level of 4.0 pCi/L, we immediately connect you with trusted, vetted radon mitigation contractors to fix the problem. EPA and IEMA recommendation: Test your home for radon every two years, and after any major renovation. If you have never tested, or it has been more than two years, do not wait — radon exposure compounds over time. We serve single-family homes, duplexes, condominiums, and multi-family dwellings throughout the greater Chicago area. Whether you're in a basement ranch home in Glen Ellyn or a high-rise condo in downtown Chicago, radon testing is relevant and important.

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.

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 .

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.

Radon is a colorless, odorless, tasteless, gas that is carcinogenic. It is naturally occurring and is present in low levels in the air we breathe outdoors (typically around 0.4 pCi/L). The EPA projects that indoor radon levels may be between 1.3 pCi/L and 4.0 pCi/L depending on your home. 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. 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) 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] When should you test for radon? Buying or selling property Every 2 years After renovations Before basement finishing 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 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.
