Microbial Processes in Stormwater BMPs

Dear Colleagues,

With the advent of low impact design (LID), a variety of stormwater best management practice (BMP) designs have been implemented to provide distributed localized stormwater treatment. While the original goal of these designs was primarily to buffer the hydrologic impacts of impervious runoff (e.g., flooding), as urban land cover has increased, there is an increased reliance on LID to concurrently improve water quality before discharging surface waters. However, recent reviews of stormwater management highlight ongoing knowledge gaps related to stormwater BMPs, including variable performance in nutrient reduction as well as a lack of knowledge about effectiveness in the inactivation of human pathogens. Microorganisms are central to these knowledge gaps, both as potential contaminants and as facilitators of contaminant transformation and degradation, yet they remain one of the least commonly studied components of stormwater BMPs.

For this Special Issue, we welcome articles that 1) describe how the performance of microbiological processes in stormwater BMPs—such as pathogen reduction, denitrification, or contaminant degradation—is maintained over long periods; 2) describe how microbiological processes are linked to stormwater BMP performance; and 3) provide new knowledge about the ecology of the fully microbial component of stormwater systems from a microbiome or ecosystem perspective. We welcome articles that focus on any type of stormwater BMP relevant to LID, such as ponds, bioretention cells, constructed wetlands, and green roofs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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.
