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.

Air Asbestos Lead Mold Radon Water Most homes in Vernon Hills have never been tested for radon - Schedule your certified inspection today." Illinois Radon Testing & Mitigation Authority (2026) US Environmental Testing Radon Is a Serious Risk in Vernon Hills, Illinois Illinois is a high radon zone, and homes in Vernon HIlls are at risk, due to soil conditions and construction methods. Why Illinois Has Some of the Highest Radon Levels in the U.S. Illinois is classified as a Zone 1 Radon State, meaning a high probability of indoor radon levels exceeding 4.0 pCi/L. What Is Radon? (Scientific Overview) 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. Radon may be detected in elevated levels in up to the third level of a dwelling.

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.

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.

USENVI provides PFAS drinking water sampling and testing for PFOA, PFOS, PFHxS, PFCAs, PFSAs and 4:2, 6:2 & 8:2 FTSA. EPA Methods 533, 537.1 and 1633. PFAS Drinking Water Testing & Analysis | PFOA, PFOS, PFHxS, PFCAs, PFSAs & Fluorotelomer Sulfonates Professional PFAS Water Sampling, Laboratory Analysis & Environmental Testing | US Environmental Testing LLC (USENVI) What Are PFAS and Why Should Drinking Water Be Tested? Per- and polyfluoroalkyl substances (PFAS) are a large family of synthetic chemicals used in manufacturing, industrial processes, firefighting foams, water-resistant coatings, food packaging, textiles, and numerous consumer products. PFAS are often called forever chemicals because many are extremely persistent in the environment and can remain in groundwater, surface water, soil, and drinking water for extended periods. PFAS contamination is an important drinking water concern for municipal water systems, private wells, commercial properties, industrial facilities, schools, healthcare facilities, property owners, and real estate transactions. US Environmental Testing LLC (USENVI) provides professional environmental sampling coordination and PFAS drinking water testing services to help identify and evaluate potential contamination. Our testing programs can include perfluorocarboxylic acids (PFCAs), perfluorosulfonic acids (PFSAs), and se lected fluorotelomer sulfonates (FTSAs), depending on the analytical method and requested laboratory analyte list. Understanding the Three Major PFAS Chemical Groups 1. PFCAs – Perfluorocarboxylic Acids PFCAs are a major group of PFAS characterized by a perfluorinated carbon chain attached to a carboxylic acid functional group. They have been used in industrial manufacturing, fluoropolymer production, surface treatments, and other chemical applications. Common PFCAs include: PFOA (Perfluorooctanoic Acid): A historically widespread PFAS associated with fluoropolymer manufacturing and industrial applications. PFBA (Perfluorobutanoic Acid) PFPeA (Perfluoropentanoic Acid) PFHxA (Perfluorohexanoic Acid) PFHpA (Perfluoroheptanoic Acid) PFNA (Perfluorononanoic Acid) PFDA (Perfluorodecanoic Acid) PFUnDA and PFDoDA PFOA is one of the most extensively studied PFAS compounds and is a significant contaminant of concern in drinking water investigations. 2. PFSAs – Perfluorosulfonic Acids PFSAs are PFAS compounds containing a perfluorinated carbon chain attached to a sulfonic acid functional group. These chemicals have been used in stain-resistant treatments, surface coatings, firefighting formulations, and industrial applications. Common PFSAs include: PFOS (Perfluorooctanesulfonic Acid): A historically important PFAS used in numerous industrial and commercial applications. PFHxS (Perfluorohexanesulfonic Acid): A persistent PFAS associated with historical firefighting foam and industrial applications. PFBS (Perfluorobutanesulfonic Acid) PFPeS (Perfluoropentanesulfonic Acid) PFHpS (Perfluoroheptanesulfonic Acid) PFOS and PFHxS are important target analytes when evaluating drinking water contamination and potential historical industrial or firefighting foam impacts. 3. FTSAs – Fluorotelomer Sulfonates Fluorotelomer sulfonates are a related group of polyfluorinated substances that can be associated with industrial applications, firefighting foams, surface treatments, and certain fluorinated products. Unlike fully perfluorinated PFCAs and PFSAs, fluorotelomer sulfonates contain a partially fluorinated carbon chain. They are important because some can undergo environmental transformation into other persistent PFAS compounds. Common target analytes include: 4:2 FTSA (4:2 Fluorotelomer Sulfonate) 6:2 FTSA (6:2 Fluorotelomer Sulfonate) 8:2 FTSA (8:2 Fluorotelomer Sulfonate) The numerical designation identifies the fluorinated and non-fluorinated carbon portions of the fluorotelomer structure. These compounds can provide additional information during investigations involving AFFF firefighting foam, industrial wastewater, groundwater, and other potential PFAS sources. Important: Not every PFAS laboratory method measures every chemical group. The requested analyte list must be verified before sampling and laboratory submission. Which EPA Method Is Used for PFAS Drinking Water Testing? PFAS analysis typically uses liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The appropriate EPA method depends on the sample matrix, target compounds, and whether the testing is intended for regulatory compliance or environmental investigation. EPA Method Primary Application Analytical Coverage EPA Method 533 Drinking water25 selected PFAS, including short-chain PFAS and selected fluorotelomer sulfonates EPA Method 537.1, Version 2.0Drinking water18 selected PFAS, including PFOA, PFOS, and PFHxS EPA Method 1633 Broader environmental matrices40 selected PFAS in groundwater, surface water, wastewater, soil, sediment, biosolids, landfill leachate, and fish tissue EPA Method 533 – Expanded Drinking Water PFAS Analysis EPA Method 533 uses isotope-dilution solid-phase extraction (SPE) and LC-MS/MS to identify and quantify selected PFAS in drinking water. This method is particularly important when evaluating a broader group of PFAS, including short-chain compounds and fluorotelomer sulfonates. Method 533 includes 4:2 FTSA, 6:2 FTSA, and 8:2 FTSA, making it an important method when these compounds are specifically requested. EPA Method 537.1 – Drinking Water PFAS Analysis EPA Method 537.1 Version 2.0 uses solid-phase extraction and LC-MS/MS to analyze 18 selected PFAS in drinking water. It includes important compounds such as PFOA, PFOS, and PFHxS. It is an EPA-approved drinking water method and is used in regulatory monitoring programs. Method 537.1 does not provide the same expanded FTSA coverage as Method 533. EPA Method 1633 – Broader Environmental PFAS Testing EPA Method 1633 is designed for PFAS analysis in a broader range of environmental matrices, including groundwater, surface water, wastewater, soil, sediment, biosolids, landfill leachate, and fish tissue. It analyzes 40 selected PFAS using LC-MS/MS. Method 1633 should not be confused with the approved drinking water compliance methods. For regulated public drinking water monitoring, Methods 533 and 537.1 are the applicable EPA-approved methods. Additional analytes must be confirmed against the method-specific target list. PFAS Reporting Limits: What Does Parts Per Trillion Mean? PFAS concentrations in drinking water are commonly reported in parts per trillion (ppt), equivalent to nanograms per liter (ng/L). A single part per trillion represents approximately one drop of water in 20 Olympic-sized swimming pools. This illustrates why specialized laboratory equipment and contamination-controlled sampling procedures are essential. Typical drinking water PFAS reporting sensitivity may be in the low single-digit ppt range, depending on the compound, analytical method, laboratory validation, and sample matrix. Measurement Equivalent Concentration 1 ppt1 ng/L 2 ppt2 ng/L 4 ppt4 ng/L 5 ppt5 ng/L 10 ppt10 ng/L 1 ppb1,000 ppt Minimum Reporting Levels (MRLs), Method Detection Limits (MDLs), and laboratory Reporting Limits (RLs) are not interchangeable. The actual reporting limit must be obtained from the performing laboratory for each analyte and analytical batch. For example, EPA's UCMR 5 monitoring program established minimum reporting levels of 3 ppt for 4:2 FTSA and 5 ppt for both 6:2 FTSA and 8:2 FTSA under Method 533. These are program-specific levels, not a guarantee of every laboratory's reporting limits. USENVI recommends reviewing the laboratory's analyte-specific reporting limits before collecting samples, particularly when evaluating results against drinking water standards or health-based advisory levels . PFAS Drinking Water Sampling Requirements & Quality Control PFAS sampling requires specialized collection procedures because PFAS-containing materials are common in everyday products and sampling equipment. Improper handling can introduce contamination and compromise analytical results. Professional PFAS sampling should follow the laboratory's approved collection instructions and applicable EPA guidance. Essential PFAS Sampling Rules 1. Use PFAS-Free Sample Bottles Use laboratory-supplied, approved polypropylene or polyethylene sample containers with compatible caps. Bottles must be appropriate for the analytical method and laboratory requirements. Do not substitute ordinary water bottles or containers. 2. Avoid Teflon and Fluoropolymer Materials Teflon, PTFE, and other fluoropolymer-containing materials must be avoided during sample collection wherever possible. This includes tubing, sample-contact equipment, certain seals, tape, and other potentially contaminating materials. 3. Collect Field Blanks A field reagent blank (FRB) is used to evaluate potential contamination introduced during transportation, handling, and field collection. The laboratory provides PFAS-free reagent water and the appropriate blank container and instructions. Additional equipment blanks or field duplicates may be required depending on the sampling plan. 4. Maintain Chain of Custody Every sample must have appropriate identification and documentation, including: Unique sample identification number Collection date and time Sampling location and source Requested EPA analytical method Requested PFAS analyte list Sampler identification Sample preservation and temperature requirements Laboratory chain-of-custody documentation Sample receipt and transfer records Chain-of-custody documentation establishes sample traceability from collection through laboratory receipt and analysis. 5. Prevent Cross-Contamination Avoid personal care products, cosmetics, sunscreen, insect repellents, water-resistant clothing, stain-resistant materials, and other potential PFAS sources during collection. Do not touch the inside of sample bottles or caps. Follow laboratory requirements for gloves, coolers, ice, and sample storage. 6. Follow Laboratory Preservation and Shipping Requirements Samples must be collected in the correct containers, preserved as required by the method, and shipped under the laboratory's specified temperature and holding-time conditions. Do not rinse or overfill prepared sample containers. How Are Public Water Systems Sampled for PFAS? Public water system sampling must be conducted according to the applicable regulatory monitoring plan, approved analytical method, and state drinking water requirements. For regulated public water systems, sampling locations commonly include entry points to the distribution system (EPTDS), where treated water enters the distribution network. A typical sampling program involves: Reviewing the water system's identification, treatment configuration, and regulatory monitoring requirements. Identifying the required entry points and sampling locations. Reviewing the laboratory sampling kit, analyte list, and collection instructions. Collecting the required drinking water samples and associated field reagent blanks. Completing sample identification, field documentation, and chain-of-custody records. Transporting samples to the qualified laboratory under required conditions. Reviewing analytical reports and comparing results with applicable regulatory requirements. For a public water system with multiple entry points, sampling requirements may apply separately to each designated location. The number and frequency of samples depend on the regulatory monitoring schedule and system-specific requirements. Private well, residential tap, commercial building, and industrial facility sampling follow different project-specific sampling plans. A residential drinking water sample should not automatically be treated as a public water system compliance sample. Who Should Consider PFAS Drinking Water Testing? PFAS testing may be appropriate for: Municipal and community public water systems Private residential wells Commercial and industrial facilities Schools, colleges, and daycare facilities Hospitals and healthcare facilities Real estate transactions and property due diligence Properties near manufacturing facilities Properties near airports and military installations Locations with historical AFFF firefighting foam use Groundwater investigations and environmental assessments Wastewater treatment and industrial discharge investigations Testing can help determine whether selected PFAS compounds are present in drinking water and provide analytical information for further investigation.
