Subject: Gen X
Sheila,
Per Linda's request, I put out a call nationally to see if anyone had experience with Gen X treatment.
Has your state (or territory or DC or the Navajo Nation) had experience with Gen X, a PFOA replacement chemical?
NC is particularly interested in treatment options.
Has your state (or others above) set a health advisory for GenX?
3. Is your state planning to set a health advisory for GenX between now and the end of 2017?
Responses — all "no's" - were received from:
Alabama
Alaska
Colorado
Delaware
Florida
Hawaii
Illinois
Indiana
Kansas
Kentucky
Massachusetts
Missouri
Montana
Navajo Nation
Nevada
New Hampshire
New Jersey
New Mexico
New York
Northern Mariana Islands
Ohio
Oklahoma
Pennsylvania

I also contacted the Water Research Foundation and they provided a link to their summary of the issues around PFAAs
from other published literature on the WRF website, published August 2016:
ttp.;f'dFy;dF.t€f:xr-€rst.-e.�r�s'���s....�tat�3C1It��3Sc€�r�� �,
.................................................. .
The conclusion:
"In summary, utilities that have shorter chain PFASs in their raw water sources at concentrations requiring treatment may need to
implement RO. NF may also be sufficient depending on membranes selected and pilot testing results. In absence of the shorter chain
chemicals, less costly treatments such as AIX and/or GAC may be adequate to remove long -chain PFASs. However, any treatment
technology will need to be evaluated for matrix effects and site -specific performance. Oxidation/reduction technologies also have the
potential to degrade some PFASs, but further research is needed for these and all techniques for treating PFASs."
People sent me links to some studies on perfluorinated compounds, but no Gen X and very little short -chain PFC
analysis. I scanned the conclusions and did not find anything inconsistent with the WRF report.
