Paper published in Water Research journal

We are pleased to announce a publication of a scientific paper entitled "Temporal variations analyses and predictive modeling of microbiological seawater quality". The article is co-authored by our Department members and published in Water Research journal.

A long scientific collaboration between the Faculty of Engineering Rijeka, Public Health Teaching Institute PGŽ, Institute for Oceanography Split and prof. Igor Mezić from the University of California at Santa Barbara has resulted in the creation of a predictive model which enables the prediction of microbiological pollution before it happens, thus increasing the quality of safety for bathing. The model presents a scientific innovation which has been published in a top journal in the field of water related research (Water Research).


Graphical Abstract


Bathing water quality is a major public health issue, especially for tourism-oriented regions. Currently used methods within EU allow at least a 2.2 day period for obtaining the analytical results, making outdated the information forwarded to the public. Obtained results and beach assessment are influenced by the temporal and spatial characteristics of sample collection, and numerous environmental parameters, as well as by differences of official water standards. This paper examines the temporal variation of microbiological parameters during the day, as well as the influence of the sampling hour, on decision processes in the management of the beach. Apart from the fecal indicators stipulated by the EU Bathing Water Directive (E. coli and enterococci), additional fecal (C. perfringens) and non-fecal (S. aureus and P. aeriginosa) parameters were analyzed. Moreover, the effects of applying different evaluation criteria (national, EU and U.S. EPA) to beach ranking were studied, and the most common reasons for exceeding water-quality standards were investigated. In order to upgrade routine monitoring, a predictive statistical model was developed.

This scientific accomplishment created a positive public interest and some elements have been published in the newspaper Novi List.
