Dave Purkiss will discuss new requirements for water treatment chemicals
Dave Purkiss, general manager of NSF Intl.’s Municipal Water Products Div., will highlight new requirements for imported drinking water treatment chemicals at 10:30 a.m. on Tuesday, June 10, in room 257B during the American Water Works Assn.'s (AWWA) ACE14 at the Boston Convention & Exhibition Center.
Purkiss’ presentation, entitled,“Raising the Bar for Treatment Chemicals,” will discuss the need for tamper-evident packaging and controls for imported chemicals and how new requirements in NSF/ANSI Standard 60: Drinking Water Treatment Chemicals — Health Effects address the issue. NSF/ANSI 60 sets health effects criteria for many water treatment chemicals, including corrosion and scale inhibitors; coagulants and flocculants; disinfection and oxidation chemicals; pH adjustment, softening, precipitation and sequestering chemicals; and other specialty chemicals used in drinking water treatment. The new requirements harmonize the frequency of retesting and address other certification practices for compliance monitoring.
Representatives from NSF will be at booth #1156 at ACE14.
