Special Issue Information

Dear Colleagues,

This Special Issue is fully dedicated to the publication of original articles and critical review papers on integrated constructed wetland systems. The focus will be on the design, operation, and performance of wetlands treating wastewater. The assessment of challenges, such as climate change, diffuse pollution, groundwater contamination and flooding, linked to wetland operation are particularly welcome.

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 papers will be 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 monthly 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 1400 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.

Abstract: Passive wastewater treatment systems are commonly applied in northern Canadian communities. Pathogen removal in these systems, which relies on natural purification, can be greatly affected by Arctic environmental conditions. In 2012, new Wastewater Systems Effluent Regulations (WSER) were implemented in Canada, but not in the far North due to the number of northern communities with limited wastewater treatment infrastructure which could present a challenge in achieving these criteria. In the summer of 2015, two sampling trips were undertaken to Pond Inlet (Nunavut) to study the disinfection performance of a single-celled wastewater stabilization pond (WSP). Sunlight disinfection was only effective close to the water surface, as UV and photosynthetically active radiation (PAR) were completely attenuated within the first 5–10 cm of the water column. The system achieved 0.76–1.28 log removal of E. coli, 0.81–1.00 log removal of fecal coliform and 0.79–1.02 log removal of total coliforms during the treatment season. The average E. coli  concentration in the WSP was 1.3 × 106  CFU/100 mL prior to annual decant, which exceeded discharge standards set by the Nunavut Water Board. Existing WSP disinfection models were selected to assess their viability to predict the performance of Arctic WSPs. In general, the models over predicted disinfection performance by an order of magnitude or more, and some were unable to replicate trends in the data. A modified model for polar WSPs should be developed, as existing models were designed for temperate or tropical regions.
