Special Issue Information
Dear Colleagues,
Poly- and perfluorinated alkyl substances (PFAS) constitue a diverse array of fully and partially fluorinated compounds, comprising over 4000 linear, branched, or cyclic variations. PFAS have been extensively found in the environment, especially wastewater treatment plants (WWTPs), largely due to the widespread domestic use of consumer products containing PFAs and commercial and industrial discharges. Furthermore, the land application of WWTP biosolids often leads to the leaching of PFAS compounds into the surface water and groundwater, while recycled wastewater is increasingly utilized for drinking water purposes, further exacerbating the issue. Growing concerns about PFAS have been raised due to their environmentally persistent and bioaccumulative nature and adverse human health effects. Comprehensive surveys in the United States and other nations have been conducted to monitor PFAS distribution, transport, transformation, and removal in both drinking water and wastewater systems. Recently, regulative agencies worldwide have proposed national drinking water standards for certain PFAS compounds, such as PFOS and PFOA to protect communities from PFAS-contaminated water. Despite the development of physicochemical treatments for PFAS, biodegradation of PFAS offers a potentially cost-effective approach. Therefore, a thorough investigation into the integration of current biotechnological treatment and emerging microbial ecology techniques is warranted to comprehend the fate, transport, and removal of PFAS in water and wastewater systems.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
