    February 16, 2016

    When: Wednesday, Feb 17, 1-2 EST

    Description: In response to current events in Flint, MI, this live webcast will feature Special Pathogens Laboratory owner, Janet E. Stout, PhD, who will describe the context of Legionnaires' disease and the new national guidelines for water systems. The ANSI/ASHRAE Standard 188-2015 Legionellosis: Risk Management for Building Water Systems is intended to provide guidelines for those involved in the creation and maintenance of human-occupied facilities, including but not limited to healthcare facilities. 

    This learning opportunity will provide information for communities and health professionals addressing outbreak situations and for those interested in Legionella prevention strategies. 

    Speaker: Janet Stout, PhD, President/Director of Special Pathogens Laboratory and Research Associate Professor at the University of Pittsburgh Swanson School of Engineering

  • Dr. Janet Stout to Speak at Cooling Technology Institute

    Can Total Bacteria Measurement Be Used To Predict Legionella Presence?
    Microbiological growth in cooling water systems presents several challenges for water treatment providers. Culture methods such as heterotrophic plate count (HPC) and “dipslides” provide valuable information related to general microbiological water quality but require several days to produce results. Alternative methods using adenosine triphosphate (ATP) measurement provide faster results and have been applied when rapid water quality assessment is necessary. Our evaluation reviewed potential applications for ATP analysis in cooling water systems. We also assessed whether total bacteria measurement using culture methods or ATP analysis can predict the Legionella presence/absence using both experimental data and data collected from field observations.

    Dr. Stout will present study results on Monday, February 9 at 11 a.m. at CTI in Nashville.

  • Free Legionella Webinar by Dr. Janet Stout, January 22, Sponsored by AWT

    Legionella Testing: Dispelling Myths and Misinformation

    11:00 am ET on Thursday, January 22, 2015

    Join the Association for Water Technologies for a free webinar with Janet E. Stout, PhD, president and director of Special Pathogens Laboratory.

    The glut of misinformation about Legionella detection continues to create unnecessary confusion. From sample collection to interpretation water treatment professionals are often asked to address well-worn myths, especially when there is a case. Some professionals may even dread testing for fear of finding a positive result. However, you can protect yourself and your clients by knowing the facts about Legionella.

    1) New research in sample collection, transport and interpretation (including flush / no flush and sample volume);
    2) How to use Legionella testing in water safety plans;
    3) What testing does and doesn’t tell you about the efficacy of your water treatment program;
    4) Legionella basics: separating myth from fact; and
    5) What to tell clients when there is a positive result.

    The webinar is open to AWT members and nonmembers. 

  • NFMT 2014: Learn the Fundamentals for Legionella Water Safety, Visit SPL at booth 2546

    February 10, 2014

    Do you know who is at risk for Legionnaires' disease in your facility? Can you identify key personnell respsonsible for water safety in your building? Do you know what parts of a water system could lead to Legionella exposure? Discover the answers to these questions and more by attending Fundamentals of Legionella Water Safety, on Thursday, March 6 at 10 a.m. in Rm 318 (Session Number: R2.18  Track:Maintenance and Operations).

    In this session, VP of SPL Consulting Services Frank Sidari will explore the benefits of taking a proactive approach to minimize the risk of Legionella in utility and building water distribution systems. He will share simple, fundamental principles to assist  you in reducing facility liability associated with Legionella and demonstrate excellence in building operation. These include: 1) Understanding risk in your building, 2) Applying effective water treatment when needed, and 3) Completing validation of effectiveness by periodic monitoring of your system and Legionella.   

    A registered professional engineer, board certified environmental engineer and certified construction document technologist, Frank provides engineering consultation on water systems impacted by Legionella. He has significant experience in all phases of water engineering projects from development through operation. His project work has focused on distribution systems, pumping, storage, treatment, and disinfection.

 Early in his career, Frank evaluated the efficacy of chlorine dioxide and published the first field evaluation of chlorine dioxide disinfection of a hospital campus water system to control Legionella in the Journal of the American Water Works Association.

    Visit Special Pathogens Laboratory at booth 2546, to talk with Frank and Dr. Janet Stout to learn more about preventing Legionella in building water systems.
