Prevent the exposure of sensitive populations to legionella bacteria, which commonly grow in large aquatic systems such as cooling towers and central air conditioning units. Exposure can result in death for those with compromised immune systems or underlying health issues.
Apex supported thirteen facilities of a major hospital group in the Northeast with their Legionella program.
The annual program is designed to confirm the efficacy of the water management practices presently in place at the locations. The sampling efforts include potable hot and cold water systems and cooling towers. As part of the sampling program Apex collected water temperature and free residual chlorine measurements. Samples were submitted to a qualified laboratory for analysis of Legionella bacteria by culture technique on specific growth, and were collected in accordance with ASTM Standard D5952-2008 and analyzed in accordance with the International Standard Method 11731 Water quality-detection and enumeration of Legionella (ISO 11731). This includes speciation and serogroup identification.
If positive tests were encountered, Apex collected follow up samples within fourteen days after the hospital personnel complete remediation activity. As part of our reporting process, Apex prepared a summary table of results that includes sample locations, laboratory results, and measurements of pH, free chlorine, and temperature.
