MABA March 15 Webinar: PFAS - What we know, what we're learning, and what's to comePer- and Polyfluoroalkyl Substances (PFAS) are a large group of man-made chemica ls that have been used in industry and consumer products worldwide since th e 1950s. Data has highlighted some important aspects of PFAS contamination across the world. (ATSDR, NCEH Fact Sheet. (cdc.gov)
This web inar will include presentations that discuss flows of PFAS compounds to WWT Fs, document PFAS loadings related to land application of biosolids, and al so provide a current update. Current research efforts regarding expo sure pathways for PFAS have focused, in part, on drinking water and wastewa ter. Less focus has been placed on PFAS impacts associated with biosolids. This webinar will include presentations that document studies related to la nd application of biosolids, and also provide a current update from EPA Off ice of Research and Development regarding recent approaches for treatment o f PFAS-impacted waters.

Presentation 1: Does land application of biosolids result in signi
ficantly increased human exposure to PFAS?
Dr. Pepper is taking o
n the PFAS issue of greatest concern to biosolids practitioners – the fate
and transport of PFAS following land application. The central question is:
does land application of biosolids result in significantly increased human
exposure to PFAS? and the corollary question, will that pathway likely res
ult in a national ban on land application? Dr. Pepper has set forth a natio
nal study of numerous sites across the country with good records on land ap
plication of biosolids to evaluate whether or not land application of bioso
lids is a significant public health route of exposure and to evaluate the p
otential for crop uptake of PFAS following land application. Funding and t
esting sites are being solicited, and webinar participants are invited to f
ollow up with Dr. Pepper for both.
Presentation 2: Statewide PFAS Assessment of WWTPs in Michigan a
nd Implications to the Beneficial Use of Biosolids for Land Application
Dorin Bogdan, Ph. D., Environmental Engineer,
AECOM
The presentation will provide a comprehensive
statewide summary of over 2,000 PFAS samples for Michigan's industrial sou
rces, influent, effluent, and biosolids. The WWTPs impact will also be comp
ared to the 2021 AECOM National WWTP Study. The presentation will summarize
over 250 PFAS samples from multiple environmental matrices of the statewid
e evaluation of 22 agricultural fields from Michigan.

cals
Mohamed Ateia Ibrahim, Ph.D., Environmental En
gineer and Group Leader, US Environmental Protection Agency (US EPA)
Separating PFAS from water and ultimately degradin
g them into products that lack carbon-fluorine bonds will be important for
decontaminating our water resources. Yet conventional treatment methods hav
e critical deficiencies, such as low affinity toward short-chain PFAS, and
are impacted by background organic and inorganic constituents. The recent a
dvancements in the development of PFAS-selective adsorbents now offer the p
ossibility of short- and long-chain PFAS treatment using regenerable sorben
ts such as cyclodextrin polymers and amine-functionalized materials. Howeve
r, currently available data the treatment of PFAS-impacted waters will nece
ssitate a treatment train approach. Such tandem-mode setups would consist o
f a separation step (e.g., adsorption or nanofiltration) followed by a dest
ruction process applied to the adsorbents, retentate, and/or regeneration s
olutions. This talk will cover some of the emerging technologies that show
promise to solve some of these challenges.
