Legionella Water Testing

COVID-19 UPDATE: Hyperion is open and available to support our customers. Our laboratory can send sampling supplies and receive samples for testing. If you have closed your building or have low occupancy due to the Coronavirus pandemic, you may need to take steps to ensure that your water system is safe before opening. See Centers for Disease Control and Prevention (CDC) Guidance for Reopening Buildings After Prolonged Shutdown or Reduced Operation article.

Call us at 210-493-7452 for any questions regarding testing your water system and cooling towers BEFORE you reopen.

Hyperion is one of the few small businesses in the U.S. that is qualified to perform testing for the presence of Legionella bacteria. Hyperion is listed as a testing lab by the Centers for Disease Control (CDC) and has obtained CDC ELITE certification and is also EMLAP certified as an accredited Environmental Microbiology laboratory.

We offer collection, sampling and on-site evaluation services as well as laboratory water testing. Legionella bacteria in a facility’s water supply can potentially lead to an outbreak of Legionnaires’ disease. Legionnaires’ disease is a serious pneumonia type respiratory illness. According to the CDC, 1 in 10 people who develop the disease will die. The only way to know for sure that Legionella bacteria are not present in a water system is to test the water. If you are a commercial hospital, nursing home, long-term care facility, spa, gym, manager of a building with cooling towers, school, or hotel, please contact us for schedules and pricing. We offer tailored water testing plans to meet your needs. Whether you need full service or are interested in using our Legionella testing kits with the included laboratory testing, we can help.

Hyperion provides environmental microbiology services for customers in locations across the United States. Our technicians in cities in California, Arizona, New Mexico, Florida, Texas, and more, provide water sample collection and onsite measurements for pH, temperature, and biocides.
