This online newsletter is a compilation of recent water-related research activities that have been peer reviewed and already released publicly through other means. The Recent Water Research (RWR) newsletter identifies relevant current research from both inside and outside EPA, and strives to provide leads to timely and relevant information that will inform decision making and program direction. The Recent Water Research newsletter is published on a semi-annual basis. Previously, it was entitled Water Research Update and Water Research Quarterly, and was published on a quarterly basis. Previous versions can be found in archives. Search EPA ArchiveYou may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
