Important Update: Comply with New GSA Water Quality Testing Requirements 

The U.S. General Services Administration (GSA) has enacted new requirements for baseline water quality testing in existing leases, addressing critical water stagnation concerns, including the risk of Legionella. As these regulations continue to roll out, it’s crucial to act quickly to ensure compliance and the safety of your facilities.

Understanding Legionella 

Legionella is a bacterium naturally found in freshwater environments such as streams, lakes, and mud. However, it can also colonize human-made water systems like cooling towers, building water systems, evaporative condensers, and recreational structures such as jacuzzies and fountains. With the increased refinement of testing methods, incidences of Legionella contamination are being reported more frequently in these human-made environments.
