The legislation concerning bathing waters (D.lgs. 116/2008 and D.M. 30/05/2010) sets 4 quality categories for bathing waters:
By the end of the 2015 bathing season all waters shall be classified at least as "sufficient". However, bathing waters may temporarily be classified as "poor". In such cases, Regions shall take the following measures taken with effect from the bathing season that follows its classification:
If a bathing water is classified as "poor" for five consecutive years, a permanent bathing prohibition shall be introduced. However, the Region may introduce a permanent bathing prohibition before the end of the five-year period if it considers that the achievement of "sufficient" quality would be infeasible or disproportionately expensive.
Available classifications are mainly based using data according to the former legislation (Dpr 470/82). D.lgs. 116/2008 (article 16, point 3) defines the equivalence between Fecal streptococci and fecal enterococci and between fecal coliforms and Escherichia coli.
For bathing season 2013 the quality of bathing water of Emilia-Romagna is "excellent" along the entire coast. The classification is based on data collected in the period 2009-2012. The tables below are also available for comparison with previous classifications (2008-2011 and 2007-2010).
It should be noted that starting from 2013 season the number of bathing waters in the province of Rimini has been reduced from 47 to 37 as provided in the resolutions of the Provincial Government (DGP 266/2012).
