Environmental Services

The publication of ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems, established a new Standard of Care for cooling towers and domestic (potable) water systems. New rules, regulations and accreditation requirements have followed. To help our Clients meet the new Standard of Care, VERTEX formed a specialized practice dedicated to providing best-in-class advisory, management and compliance services for Building Water Systems. Our work in Building Water Systems is performed by a dedicated Team, trained by Gordon & Rosenblatt (G&R) and supported by the full organizational resources of VERTEX, giving us the ability to meet our Client’s needs quickly and efficiently.


Building Water Management Programs

VERTEX develops audit-ready Water Management Programs to prevent harm from multiple hazards, including Legionella and Lead. Our Programs comply with ANSI/ASHRAE Standard 188-2015, NSF Protocol 453 and applicable rules, regulations and codes.

Education & Training About Building Water Systems

VERTEX provides education and training of our Clients’ staff, so everyone understands how and why we manage building water systems. By engaging all parties, with respect and full transparency, we enhance the sustainability and the quality of our Clients’ outcomes.

Analysis of Building Water Systems

VERTEX conducts on-site evaluations and describes, in words and schematics, cooling tower and domestic (potable) water systems. This includes measurements and tests of the physical and chemical conditions. We then perform a systematic analysis of the system for potentially hazardous conditions that, in the absence of control, can support the amplification and transmission of Legionella and other disease-causing bacteria. When we find problems, we do the work needed to diagnose the root causes and recommend practicable, sustainable solutions.

Implementation Support Services

VERTEX provides a range of services to support implementation of our Clients’ Water Management Programs, from periodic review of Verification and Validation records to full-time, on-site management of compliance documentation, to oversight of third-party water treatment firms.

Building Water Sampling Plans

VERTEX designs comprehensive building water sampling plans, consistent with rules, regulations and best practices, to make sure that sampling protocols are appropriate for the facility, and that test data are representative of the building water system and provide as much useful information as possible.

Independent Sampling of Building Water

VERTEX collects environmental water samples and transports them to third-party testing laboratories, to be analyzed for Legionella, lead, disinfection by-products and other contaminants.

Building Water Systems Data Management & Analytics

VERTEX helps manage Verification and Validation data from environmental water sampling, so that it is easy to find when needed. We also help analyze and interpret the data, including trending over time, to help predict and head off problems before there is harm.

Audit & Survey Preparedness

VERTEX reviews Verification and Validation records and works with Clients’ staff to prepare for independent audits and healthcare-accreditation surveys relating to building water systems.
