Westlake Water Solutions Reminds About Safety Risks Posed by Improper Pool Chlorination

Pool Chemistry Resources Support Summertime Proper Aquatic Chlorination

HOUSTON--(BUSINESS WIRE)--Commercial pools around the country will soon open, ushering in the start of the summer season. In recognition of National Water Safety Month, which began on May 1st, Westlake Water Solutions, a business unit of Westlake Corporation (NYSE: WLK); and NSF International, a leading public health and safety organization that provides testing and standards, are reminding health inspectors and pool operators about the importance of using properly specified chlorine tablets in their certified sanitizing systems.

“Along with the sun and fun that come with commercial water, it is important to properly chlorinate commercial pools with feeder systems that can keep up with degradation of chlorine due to heavy bather loads, rain and the sun’s ultraviolet rays,” said Austin Looper, director, Westlake Water Solutions business. “Organizations like NSF, the U.S. Centers for Disease Control and Prevention and the American Chemistry Council offer tools in the form of standards, codes and training videos to help safeguard against accidents and improper chemical application. For example, using chlorine tablets that are not NSF Standard 50 certified for use in their feeder can result in problems like over or insufficient chlorination of the water.”

“NSF International tests and certifies commercial and residential pool products to the requirements of NSF/ANSI/CAN 50,” according to Theresa Bellish, senior global managing director at NSF.

NSF’s Ann Arbor, Michigan, labs are recognized around the world for their accuracy to verify performance of chemical delivery systems and tablets, which are tested in conjunction with one another. Only chlorine tablets specified for use in a given system will maintain compliance to Standard 50, mandated by most states and local municipalities.

Westlake Water Solutions also reminds pools operators of the following resources available to them ahead of the Memorial Day weekend to help maintain healthy water:
