2026 in-season sample timeline
No individual in-season sample feed has been published for Mt.100 Dx Fiume Sisto yet. The official 2025 classification above, from the annual EU Bathing Water report, is the most current rating available for this beach.
How measurement works
Under the EU Bathing Water Directive, national authorities take water samples through the bathing season and test them for two indicator bacteria: intestinal enterococci and E. coli. Higher counts of either indicate a greater risk of contamination from sewage or agricultural runoff.
At the end of each season, the full set of results is reported to the European Environment Agency, which assigns one of four classifications — Excellent, Good, Sufficient or Poor — based on the statistical spread of the last four seasons' samples, not a single reading. That's why the rating published in spring 2026 covers the 2025 season, and why one bad sample doesn't necessarily change the rating on its own.
