Commercial Final Barrier

2012 ASPE Webinar Series

Deliver Safer Water: Commercial Final Barrier

Earn Continuing Education Credits: This one-hour contact program provides 0.1 CEU or 1.0 PDH.


Final barrier provides water treatment at the source of consumption. This new approach to water treatment allows the removal of contaminants to lower levels than central treatment, removal of contaminants not addressed by central treatment, and removal of contaminants that are introduced during or after central treatment. Civil engineers and utility managers globally are beginning to recognize that treatment at the Point-of-Use (POU) may be more cost-effective than centralized treatment. Point-of-Use (POU) or Point-of-Entry (POE) devices have been tested and certified for many different classes of contaminants:

  • Inorganics such as lead and copper
  • Radium & Other Radionuclides
  • Volatile Organic Chemicals such as disinfection byproducts
  • Synthetic Organic Chemicals
  • Microbiologicals such as bacteria, cyst and virus
  • Aesthetic concerns such as particulates, taste and odor

This one-hour webinar of the final barrier concept will provide global examples of final barrier implementation, the US regulatory perspective, and guidance for residential consumers pursuing this emerging paradigm.



The Speaker: Pauli Undresser - Director of Regulatory and Technical Affairs, Water Quality Association (WQA)

Pauli Undesser is the Director of Regulatory and Technical Affairs for the non-profit Water Quality Association (WQA). She also maintains the title of Toxicology Manager for the WQA Gold Seal Product Certification Program and is the technical liaison for the Water Quality Research Foundation (WQRF). WQA is an international trade association of more than 2,500 member companies worldwide who manufacture and sell point-of-use (POU) and point-of-entry (POE) water treatment equipment. WQRF formed in 1949 to serve, on behalf of the Water Quality Association (WQA), as a universally recognized, independent research organization.

Pauli holds a bachelor’s degree in Chemistry from the University of Illinois at Urbana-Champaign and a master’s degree in Biochemistry from Northern Illinois University. After 11 years of applied laboratory work ranging from wet chemistry and organic chemistry to molecular biology and protein expression, her background in chemistry and biochemistry were applied at the Water Quality Association managing third party certification of drinking water treatment products and developing an internal toxicology program. Once those positions were well under her belt, Pauli transitioned into her current role as Director of Regulatory and Technical Affairs.
