ACM: Asbestos-containing material, any material with >1% asbestos;TSI: Thermal system insulation, ACM applied to pipes, fittings, boilers, ducts, etc. to prevent heat loss/gain; PACM: Presumed asbestos-containing material,TSI and surfacing material in buildings built ≤1980, treated as ACM until proven otherwise; PLM: Polarized light microscopy, microscopy technique to identify asbestos fibers; TEM: Transmission electron microscopy, high-resolution imaging method Thermal System Insulation (TSI) Understanding Asbestos and Thermal System Insulation What Is Asbestos-Containing Thermal System Insulation (TSI), and Where Is It Commonly Found in Buildings? UNDERSTANDING ASBESTOS AND THERMAL SYSTEM INSULATION How Can You Identify Asbestos-Containing Pipe Insulation in Commercial, Industrial, and Residential Buildings? Thermal system insulation is particularly important because many historical insulation products contain asbestos and some can release microscopic fibers when damaged or disturbed. Pipe insulation may deteriorate over time because of moisture, vibration, mechanical damage, maintenance activities, and aging. Fibers may become airborne when workers cut, drill, scrape, remove, or improperly repair asbestos-containing insulation. This creates potential exposure concerns for maintenance personnel, plumbers, HVAC technicians, construction workers, building occupants, and contractors. The risk depends on the material's asbestos content, condition, accessibility, and the activities being performed around it. Proper inspection, material identification, maintenance planning, and professional asbestos management help prevent unnecessary exposure. What Is the Difference Between Thermal System Insulation (TSI), Surfacing Materials, and Other Asbestos-Containing Building Materials? Several types of asbestos were used historically in insulation and other industrial products. The three commonly discussed commercial asbestos types are chrysotile, amosite, and crocidolite. Chrysotile is commonly called white asbestos . Amosite is commonly called brown asbestos. Crocidolite is commonly called blue asbestos . Chrysotile was widely used in numerous building and mechanical insulation products. Amosite and other amphibole asbestos types were also used in certain historical insulation applications. Crocidolite Is widely used in industrial applications due to its tensile strength and heat resistance. Typically found in insulation products, fireproof textiles, cement blends, spray-on coatings, plastics, pipe insulation, cigarette [Micronite] filters, brake liners, furnace and oven liners, and more. It's use has declined as result of Crocidolite's carcinogenic properties. The specific asbestos type cannot reliably be determined by looking at the material. Laboratory analysis by an appropriately qualified laboratory is necessary to identify asbestos and, when required, characterize the asbestos mineral type. Asbestos Identification, Inspection, and Testing Presumed Asbestos-Containing Material, or PACM, is a regulatory designation used under OSHA's asbestos construction standard. OSHA defines PACM as thermal system insulation and surfacing material found in buildings constructed no later than 1980. This means certain older pipe insulation, boiler insulation, and surfacing materials must be treated as presumed asbestos-containing materials unless the presumption is properly rebutted under applicable OSHA requirements. The designation is particularly important for contractors, employers, building owners, and maintenance personnel planning work that could disturb historical insulation. A building's construction date alone does not prove that every insulation product contains asbestos. However, the PACM designation establishes important workplace obligations. Qualified inspection, appropriate testing, and proper documentation can help determine the material's status . Asbestos Exposure, Safety, and Risk Management Is Asbestos-Containing Thermal System Insulation Dangerous If It Is Intact and Undisturbed? Intact, properly maintained asbestos-containing thermal system insulation generally presents a lower risk of fiber release than insulation that is damaged, deteriorating, or disturbed. Asbestos exposure occurs when microscopic fibers become airborne and are inhaled. However, intact material is not automatically harmless. Its condition, location, accessibility, and likelihood of future disturbance must be considered. If asbestos-containing insulation is in good condition and unlikely to be disturbed, professional management may be preferable to unnecessary removal. Building owners should maintain appropriate records, monitor material condition, and communicate relevant asbestos information to contractors and maintenance personnel. Any planned work that could disturb the insulation should be evaluated before work begins. USENVI expert takeaway: Asbestos management is not simply a decision to remove or leave material. It requires an informed evaluation of condition, exposure potential, and future building activities. Can Asbestos Fibers Become Airborne When Old Pipe Insulation Is Damaged or Disturbed? Yes. Asbestos fibers can become airborne when asbestos-containing pipe insulation is damaged, deteriorates, or is disturbed. Potential fiber-release activities include: Cutting or drilling. Scraping or sanding. Breaking or crushing. Mechanical demolition. Improper insulation removal. Certain maintenance and repair activities. Asbestos fibers are microscopic and cannot be reliably identified by looking at dust or debris. Air monitoring, when appropriate, must be conducted using recognized sampling and analytical procedures by qualified professionals. The presence of visible dust does not establish an asbestos concentration, and the absence of visible dust does not prove that airborne asbestos is absent. USENVI expert takeaway: Suspected asbestos insulation should be evaluated before disturbance, and potential exposure should be addressed through appropriate professional controls and assessment. What Should Contractors, Plumbers, HVAC Technicians, and Maintenance Workers Know Before Working Around Suspect Asbestos TSI? Address pre-work asbestos assessments, building surveys, worker awareness, applicable OSHA requirements, work planning, and the importance of not disturbing suspect insulation before appropriate evaluation. Should Asbestos-Containing Thermal System Insulation Be Removed, Repaired, or Encapsulated? Asbestos-containing thermal system insulation does not always need to be removed. The appropriate management decision depends on the material's condition, accessibility, potential for disturbance, building use, and planned renovation or demolition. When material is intact and properly maintained, continued management may be appropriate. When material is damaged, professional repair, encapsulation, or enclosure may be considered. Removal may be appropriate when asbestos-containing insulation interferes with construction, renovation, equipment replacement, or demolition. Encapsulation involves applying an appropriate material to help seal or bind asbestos fibers. Enclosure involves creating a protective barrier around the asbestos-containing material. Neither option is appropriate for every condition. A qualified asbestos professional should evaluate the material and recommend an appropriate management strategy. Chicago and Illinois Asbestos Regulations and Professional Services What Are the Federal, Illinois, and Chicago Asbestos Regulations Governing Thermal System Insulation? Several federal, state, and local regulations may apply to asbestos-containing thermal system insulation. The primary federal workplace regulations include OSHA's General Industry Asbestos Standard, 29 CFR 1910.1001, and Construction Asbestos Standard, 29 CFR 1926.1101. The U.S. Environmental Protection Agency administers federal asbestos requirements, including the National Emission Standards for Hazardous Air Pollutants, commonly called NESHAP. Illinois EPA administers the delegated asbestos NESHAP program in Illinois. The Illinois Department of Public Health administers state licensing requirements for covered asbestos-related activities in schools and public and commercial buildings. Chicago and other local jurisdictions may impose additional notification, permitting, or fee requirements. These regulations address different aspects of asbestos identification, worker protection, project notification, abatement, and disposal. The specific requirements depend on the building, material classification, quantity, work activity, and project location. Is an Asbestos Ins pection Required Before Renovating or Demolishing an Older Building in Chicago or Illinois? An asbestos inspection is generally an important prerequisite to regulated renovation and demolition work, and specific inspection and notification requirements apply under federal and Illinois regulations. Federal NESHAP requires a thorough inspection of affected facilities before covered demolition or renovation operations. Illinois EPA requires advance notification for applicable regulated asbestos removal projects when the amount exceeds specified thresholds. Illinois identifies notification thresholds of more than 160 square feet, 260 linear feet, or one cubic meter of regulated asbestos-containing material for applicable renovation projects. Notification generally must be submitted at least ten working days before the covered work begins. Demolition requirements must be evaluated separately; the notification obligation is not limited to whether asbestos removal is planned. Illinois Department of Public Health licensing requirements and local Chicago or county requirements may also apply. There are specific exemptions and distinctions based on building type and project circumstances, including certain residential structures. Who Is Qualified to Inspect, Sample, and Remove Asbestos-Containing Thermal System Insulation in Illinois? Different asbestos activities require different professional qualifications. An asbestos inspector identifies suspect materials, performs or oversees appropriate sampling, and documents findings. An asbestos project designer prepares specifications and plans for covered abatement projects. An asbestos supervisor oversees applicable abatement operations. An asbestos worker performs regulated asbestos abatement work. An asbestos contractor is responsible for conducting covered abatement projects and meeting applicable licensing and insurance requirements. An air-sampling professional performs appropriate air monitoring and clearance sampling within the scope of their qualifications. In Illinois, the Illinois Department of Public Health administers licensing requirements for asbestos-related activities in schools and covered public and commercial buildings. Property owners should verify the qualifications, licensing, and credentials of the individuals and companies performing the specific work. How do I know if I have asbestos in my home (in floor tile, ceiling tile, shingles, siding, etc.)? The only way to be sure whether a material contains asbestos is to have it tested by a qualified laboratory. EPA only recommends testing suspect materials if they are damaged (fraying, crumbling) or if you are planning a renovation that would disturb the suspect material. Samples should be taken by a properly trained and accredited asbestos professional (inspector). What are the health risks if I have asbestos in my home, building, apartment, or school? Asbestos that is in good condition and left undisturbed is unlikely to present a health risk. The risks from asbestos occur when it is damaged or disturbed where asbestos fibers become airborne and can be inhaled. Managing asbestos in place and maintaining it in good repair is often the best approach. 3.Where can I find someone to remove the asbestos in my home? You can perform an internet search for “asbestos contractor” and the location of your home. Contact your state to determine what state training and accreditation requirements may exist for both the contractor and their workers. EPA recommends that you use an asbestos contractor that is properly trained to handle asbestos. 4.My attic has vermiculite insulation in it. Am I at risk? Should I take it out? If you have vermiculite insulation in your home, you should assume this material may be contaminated with asbestos and be aware of steps you can take to protect yourself and your family from exposure to asbestos. The EPA recommends that vermiculite insulation be left undisturbed. Airborne asbestos fibers present a health risk through inhalation, so the first step is to not disturb the material, which could release fibers into the air. If you disturb the insulation, you may inhale some asbestos fibers. The degree of health risk depends on how much and how often this occurred. If you choose to remove the vermiculite insulation, this work should be done by a trained and accredited asbestos abatement contractor that is separate and independent from the company that performed the assessment of the vermiculite insulation to avoid any conflict of interest. What are the health risks if I have asbestos in my home, building, apartment, or school? Asbestos that is in good condition and left undisturbed is unlikely to present a health risk.

I am thinking about buying a house but it has vermiculite attic insulation in it. Should I have it removed before or after I buy the house? Removal of the vermiculite insulation may not be necessary if it is confined in a manner where it will be left undisturbed. If you choose to have the vermiculite insulation removed, the EPA recommends that you use a trained and accredited asbestos contractor that is separate and independent from the company that performed the assessment of the vermiculite insulation to avoid any conflict of interest. I use/used vermiculite to enhance my potting soil. Should I be concerned? EPA's investigation (see report) into these products indicates that consumers face only a minimal health risk from using vermiculite products at home or in their gardens. To further reduce the risk associated with the occasional use of vermiculite products during gardening activities, EPA recommends that consumers: • Use vermiculite outdoors or in a well-ventilated area. Avoid creating dust by keeping vermiculite damp during use. Avoid bringing dust into the home on clothing. Although EPA does not endorse the use of any particular product, consumers may choose to use: Premixed potting soils, which ordinarily contain more moisture and less vermiculite than pure vermiculite products and are less likely to generate dust. Soil amendment materials other than vermiculite, such as peat, sawdust, perlite, or bark. How do I get certified as an asbestos professional? To become a properly trained and accredited asbestos professional you will need to seek training from a training provider that offers courses approved by the EPA or a state to conduct asbestos training pursuant to the Asbestos Model Accreditation Plan. Most states also require a license to perform this work. Your training course completion certificate is a general prerequisite to applying for such a license. The training courses vary in length from 2 to 5 days depending upon the type of work you wish to perform. Accredited asbestos training courses are offered in five separate disciplines; Asbestos Abatement Worker, Asbestos Abatement Supervisor, Inspector, Management Planner and Project Designer. Some states may refer to these training disciplines by different, yet similar names. Where can I find someone to test a material to see if it contains asbestos? You can perform an internet search for “asbestos inspection and assessment” and the location of your home. Also, make sure that the inspector is properly trained and accredited by your state.

Call 331-462-2711 PFAS in Drinking Water Current Status On May 18, 2026, EPA proposed two rules related to PFAS in drinking water. The first would rescind Biden-era regulations for PFHxS, PFNA, HFPO-DA, and Hazard Index mixtures . The second would extend the compliance deadlines for the PFOA and PFOS Maximum Contaminant Levels (MCLs) for two additional years, until 2031 . The comment periods for each rule close July 20, 2026. EPA also announced a public hearing will be held on July 7, 2026 where the public can provide comments on the rules. The deadline for registration to attend or provide verbal public comment is July 1, 2026. Last Updated 9/18/2026 Source: Environmental & Energy Law Program, Harvard Law School Why it Matters PFAS, often called “forever chemicals,” are a family of man-made chemicals featuring a strong carbon fluorine bond that makes the chemicals extremely durable. Studies have found significant PFAS contamination in the country’s public drinking water supplies. At high levels of exposure, PFAS have been shown to cause serious human health problems.The Biden-era PFAS rule under SDWA establishes deadlines for drinking water systems to test for PFAS by 2027 and to meet specific PFAS standards by 2029. The regulation is a significant step toward protecting public health as envisioned in EPA’s 2021 PFAS Strategic Roadmap.

Circuit heard oral arguments in American Water Works Association, et al. v. EPA. May 18, 2026 EPA proposed two rules related to PFAS in drinking water. The first would rescind Biden-era regulations for PFHxS, PFNA, HFPO-DA, and Hazard Index mixtures. The second would extend the compliance deadlines for the PFOA and PFOS Maximum Contaminant Levels (MCLs) for two additional years, until 2031. The comment periods for each rule close July 20, 2026 . EPA also announced a public hearing will be held on July 7, 2026 where the public can provide comments on the rules. The deadline for registration to attend or provide verbal public comment is July 1, 2026 . April 6, 2026 EPA published its sixth draft Contaminant Candidate List (“CCL 6”) for public comment, which lists contaminants that are known or anticipated to occur in public water systems and may require regulation under the Safe Drinking Water Act (SDWA) in the future. PFAS were included on this list. EPA stated it will decide whether to regulate at least five contaminants from the CCL. Comments on CCL 6 are due June 5, 2026. March 19, 2026 The D.C. Circuit denied EPA’s request to sever and hold in abeyance challenges to drinking water standards for four Index PFAS that the agency now intends to repeal. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). Feb. 19, 2026 EPA filed a motion to sever and hold in abeyance claims related to Index PFAS regulations in American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). In its motion, EPA stated it intends to “commence the rulemaking process imminently” to rescind the portion of the Biden-ERA PFAS drinking water rule that issues regulatory determinations and standards for the Index PFAS. Jan. 12, 2026 The D.C. Circuit issued an order denying EPA’s previous request to summarily vacate four of the six Biden-era PFAS drinking water rules. The court explained that despite EPA’s arguments that the rules were procedurally inadequate, the merits of the parties’ positions were “not so clear as to warrant summary action.” American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir. June 07, 2024). Sept. 11, 2025 EPA requested the D.C. Circuit vacate four of the six Biden-era PFAS drinking water rules, arguing that the agency failed to follow the Safe Drinking Water Act’s public comment procedures when issuing those standards. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). July 22, 2025 The D.C. Circuit granted EPA’s motion to reactivate the litigation regarding a challenge by industry and utilities to the Biden-era PFAS drinking water rule. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). May 14, 2025 EPA announced it will delay implementation of the SDWA Biden-era rule for two PFAS chemicals, PFOS and PFOA, extending the compliance deadline for drinking water suppliers to meet standards set for those two chemicals to 2031, providing water suppliers two additional years to comply. EPA also stated it will rescind the standards set in the Biden-era rule for four other PFAS chemicals. EPA expects to reissue a new regulation in spring 2026 and will continue to defend the other standards set in the Biden-era rule for PFOS and PFOA in the litigation challenging the rule. American Water Works Association, et al., v. EPA, (D.C. Cir. June 2024) Docket Number 24-1188. April 28, 2025 EPA announced it intends to address PFAS contamination . EPA also stated it will address concerns raised by water providers regarding the timing of the SDWA PFAS rule’s drinking water standards and monitoring deadlines. April 7, 2025 The court granted an unopposed EPA motion to extend the stay for 30 additional days. American Water Works Association, et al., v. EPA, (D.C. Cir. June 2024) Docket Number 24-1188. Feb. 7, 2025 The Court agreed to grant EPA’s motion to hold the case in abeyance for 60 days while EPA reevaluates the Biden-era rule. American Water Works Association, et al., v. EPA , No. 24-1188 (D.C. Cir.). Biden Administration June 7, 2024 Trade associations representing public water providers and industry challenged the EPA PFAS drinking water rule, arguing, among other issues, that EPA did not rely on the best available science, took unlawful novel approaches, and underestimated the costs of the regulation. Multiple environmental groups and 18 states have intervened in support of the rule. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.)., consolidated with other challenges to the rule. April 26, 2024 EPA, under the Safe Drinking Water Act, finalized the PFAS National Primary Drinking Water Regulation Rule, setting drinking water standards for certain PFAS chemical subtypes. The rule establishes legally enforceable levels, called Maximum Contaminant Levels (MCLs), for six types of PFAS in drinking water systems. For two other specific PFAS chemicals, EPA set Maximum Contaminant Level Goals (MCLGs), non-enforceable, health-based, public drinking water objectives, at zero.

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?
