Building Water Quality Management Services

Corona’s science, engineering and design team has unequaled project experience working with clients on building water management to reduce the risks associated with Legionella and exposure to other harmful contaminants. Our team provides comprehensive building water quality management services that include:

Who Needs a Building Water Management Plan?

Many large buildings need a water management plan to reduce the potential exposure to Legionella and other harmful bacteria that can grow in building plumbing systems. Building water quality is not regulated and the legal responsibility of the building owner and manager. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 188 has established minimum legionellosis risk management requirements for building water systems. The Centers for Disease Control and Prevention (CDC)  also provides an easy-to-understand toolkit ( to help building owners and managers evaluate if they need a water management plan.

Is your Building in Compliance with the new Centers for Medicare and Medicaid Services requirement?

On June 2, 2017, the Centers for Medicare and Medicaid Services (CMS) issued for healthcare facilities to establish water management plans to protect the health and safety of their patients. Facilities that are “unable to demonstrate measures to minimize the risk of LD are at risk of citation for non-compliance with the CMS Conditions of Participation. Accrediting organizations will be surveying healthcare facilities deemed to participate in Medicare for compliance with the requirements listed in this memorandum, as well, and will cite non-compliance accordingly.”

This requirement has raised the bar significantly for any institution receiving federal health care dollars through the CMS.

Our Team

Corona has been at the forefront of developing these standards with NSF and CDC.  Drs. Jen Clancy and Sheldon Masters are on the NSF Joint Committee developing NSF Standard 444 – “Prevention of Injury and Disease Associated with Building Water Quality”.  Sheldon and Jen are principal investigators on a Water Research Foundation project titled “Customer Messaging on Plumbing System Issues” which focuses on education and prevention of Legionnaires’ disease in building water systems. Our applied research laboratory at the Philadelphia Navy Yard conducts OPPPs research and analyzes water samples for all the OPPPs of interest. This is important in assessing initial and ongoing building water quality and to support investigations including sporadic cases and outbreaks.
