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.

Illinois has some of the highest radon potential areas in the country, with Northern Illinois frequently reporting elevated indoor radon levels. Because radon cannot be seen, smelled, or tasted, testing is the only reliable way to determine whether a property has elevated concentrations. Illinois health guidance recommends taking corrective action when 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? 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? #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 prepare for your radon test How to prepare for a closed building radon measurement: Preparing for a Closed-Building Radon Measurement Steps to Follow Before and During Testing by US Environmental Testing To ensure accurate radon measurement results, follow the steps below before and during the testing period. 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. Within 24 hours, you will receive a formal report via email or fax. We can also send a hard copy by mail upon request. Following these guidelines ensures the most accurate radon measurement possible.
