Pool & Spa Service Providers Will Notice Subtle But Significant Changes

(ALEXANDRIA, VA) - The Association of Pool & Spa Professionals (APSP) announces the newly revised ANSI/APSP/ICC-11 2019 Standard for Water Quality in Public Pools and Spas and features significant changes that will impact pool and spa service professionals across the nation.  

The ANSI/APSP/ICC-11 2019 Standard for Water Quality in Public Pools and Spas is the first comprehensive, data-driven and knowledge-based national Standard for pool and spa water quality and chemistry.  The Standard is ideal for understanding the minimum guidelines surrounding water quality parameters in public swimming pools and spas to be used for bathing and operated by an owner, licensee, or concessionaire, regardless of whether a fee is charged for use.

ANSI/APSP/ICC-11 2019 is different from its 2009 predecessor in that the new Standard addresses advances in technology and an improved understanding of water quality and chemistry. “For a decade, pool and spa industry service professionals have been using Standard 11 to advance customer satisfaction through improved water quality,” said APSP Recreational Water Quality Committee Chairman, Joe Laurino, Ph.D. “This revised standard addresses secondary disinfection systems, the impact of stabilized chlorine on disinfection, and other recent industry developments affecting bather safety. Our hope is that service professionals and policymakers alike continue to be advocates for better water quality and adopt these strategies, based on the latest technical information available, in their everyday applications.” 

“Improving water quality and chemistry are essential to the pool and spa industry,” said APSP Vice President of Standards and Technical, Carvin DiGiovanni. “ Taking into account the latest technologies and cost-effective strategies for dealing with resource scarcity, the ANSI/APSP/ICC-11 2019, helps the industry provide mission critical services more sustainably.”
