Tucson’s Source Water Evaluation of PFAS

Presented by Jeff Biggs, Administrator – Source Water Division, Tucson Water

Scientific research has indicated that exposure to certain contaminants of emerging concern (CECs) pose risks to human health.  To respond to these potential health concerns, Tucson Water established the Sentry Program in 2008. The Sentry Program has detected trace levels of CECs at several strategic locations within in the drinking water system. Tucson Water has been tracking annual sampling results within their potable and reclaimed water systems to proactively identify and address potential CECs contamination issues.

Tucson Water first became aware of PFAS detections within its system in 2009. The PFOA/PFOS detections from 2009-2016 were well below the provisional Health Advisory (HA) established by the EPA in 2009. The HA was set for PFOS concentration not to exceed 200 ppt and PFOA concentration not to exceed 400 ppt. EPA revised the HA in May, 2016 to PFOA+PFOS not to exceed 70 ppt. Tucson Water  began the process of systematically evaluating its potable and reclaimed systems for PFAS impacts.  Tucson Water staff took many proactive steps to ensure our customers would not be adversely impacted by PFAS in their drinking water.

This presentation will illustrate efforts taken by Tucson Water to mitigate PFAS contamination within the Tucson Water potable and reclaimed water systems.e.
