City of Prescott Provides PFAS Testing Update

City Drinking Water is at non-detectable levels of PFOA and PFAS

Prescott, Arizona (October 4, 2022) — The latest results are in from the most recent testing of City wells for PFAS chemicals.  The City tested the blend of Well 2 and Well 4 in Chino, known as EPDS 11.   The samples taken on September 7 resulted in non-detects (<1.89) for both PFOS and PFOA in these wells. 

We also received results showing that Airport Wells 2 and 3 were both “non-detects” for PFOA and PFOS.  Airport Well 5 reported PFOS (8.14 ppt) and PFOA (11.9 ppt) as expected. At this time, Airport Wells 2 and 3 are available for service and Airport Well 5 is not used as a part of our drinking water system.   

“These results indicate that our blending plan is working as intended,” said Mayor Phil Goode. “Our Public Works team has done an excellent job of predicting outcomes, which are validated by these test results.  We will continue to monitor the levels, as we begin a plan to remediate these chemicals from our drinking water supply.” 

Regular testing of City wells will be ongoing, to assure the safety of our drinking water quality.
