Additional Emerging Contaminants: Testing options for other chemical, microbial, inorganic, and organic contaminants based on the water source and project objectives. PFAS, PFCAs, PFSAs & Fluorotelomer Compounds: What Should Be Tested? PFAS contamination is an increasingly important environmental concern for homeowners, commercial property owners, municipalities, industrial facilities, and real estate professionals. PFAS is a large family of manufactured chemicals used in numerous industrial applications and consumer products. Certain PFAS compounds are highly persistent in the environment and may enter groundwater and drinking water supplies. A comprehensive PFAS water testing program may include: Perfluoroalkyl carboxylic acids (PFCAs). Perfluoroalkyl sulfonic acids (PFSAs). Perfluorooctanoic acid (PFOA). Perfluorooctanesulfonic acid (PFOS). Perfluorohexanesulfonic acid (PFHxS). Perfluorononanoic acid (PFNA). Perfluorobutanesulfonic acid (PFBS). Fluorotelomer sulfonic acids (FTSAs). 6:2 fluorotelomer sulfonic acid (6:2 FTS). 8:2 fluorotelomer sulfonic acid (8:2 FTS). Other applicable n:2 fluorotelomer compounds and emerging PFAS analytes. The appropriate analytical panel depends on the water source, project objectives, regulatory requirements, and laboratory capabilities. EPA Methods 533 and 537.1 are established analytical methods for measuring specified PFAS compounds in drinking water. Legionella Water Testing for Commercial Buildings & Facilities Need Legionella testing for a commercial building, hospital, nursing home, school, hotel, apartment complex, or industrial facility? Legionella is a naturally occurring bacterium that can grow in building water systems under favorable conditions. Exposure can occur when contaminated water becomes aerosolized and is inhaled. Legionella bacteria can cause Legionnaires' disease, a serious form of pneumonia. US Environmental Testing LLC coordinates environmental Legionella water testing and sampling services for: Hospitals and healthcare facilities. Nursing homes and assisted living facilities. Hotels, resorts, and hospitality properties. Commercial office buildings. Apartment complexes and multifamily properties. Schools, universities, and daycare facilities. Cooling towers and industrial water systems. Buildings undergoing reopening or water system evaluations. Testing may include Legionella pneumophila identification, Legionella species analysis, environmental water sampling, and laboratory culture or PCR analysis, depending on the project objectives. Lead in Drinking Water Testing How do I know if my drinking water contains lead? Should I test the water in an older home, school, daycare, commercial property, or apartment building? Lead can enter drinking water through deteriorating plumbing materials, lead service lines, solder, faucets, and fixtures. Water may contain lead even when it looks completely clear. We coordinate professional lead-in-water sampling and laboratory analysis for: Residential drinking water. Schools and daycare facilities. Commercial buildings. Hospitals and healthcare facilities. Apartment complexes and multifamily properties. Drinking fountains and water dispensing fixtures. Private wells and other applicable water sources. Laboratory analysis can determine whether lead is present and quantify the concentration in the submitted sample. Who Needs Professional Water Testing?

Keep exterior doors and windows for 12 hours prior to the start of this test, the continual use of exterior doors for normal entry and exit is allowed and expected. Keep all windows, doors and other openings to the outside closed during the testing period. 2. Set the thermostat to 72 Degrees Fahrenheit (plus or minus 5 degrees Fahrenheit) and set to "Auto". Do not change the testing environment in any way, including but not limited to, opening windows, leaving doors open, changing thermostat or fan settings or cause outside air to be introduced into the home. 3. Operation of mechanical systems that draw air out of building may adversely affect the test results. Any test device(s) placed should not be disturbed and the location should not be changed. Report to Northern Illinois Radon LLC any circumstances or events that may cause the conditions outlined above to be violated in any way or manner, and any circumstance that may have an influence of the testing conditions or results. If any of these guidelines are not followed and the test results appear to be incorrect, a re-test may be required. 4. When the radon monitors are placed and test is started, tamper evident seals will be installed on all windows. These should not be removed until the measurement is concluded. 5. Forty-eight (48) hours after the start of the radon measurement, the measurement will conclude and you will have (verbal) results at time of monitor retrieval. A formal report will be prepared within 24 hours and delivered electronically (email, fax), or by mail (upon request). Blog 331-462-2711 Request Quote
