Spanish River is a saltwater beach in Palm Beach County, Florida. Across 26 bacteria samples collected between 2022 and 2024 at nearby monitoring stations, it earns a Beach Safety Grade of F — Failing.
About 39% of samples at Spanish River exceeded the EPA Beach Action Value of 235 CFU/100 mL for Escherichia coli — the threshold at which water managers typically post a swimming advisory. In practice that means the safe-swimming limit was frequently crossed here over the monitored period. Bacteria samples exceed the safe-swimming threshold a large share of the time — this beach flags advisories often.
Read this grade as directional rather than settled: it draws on a single monitoring station and rests on only 26 samples. That is enough to classify how the water has behaved, but not enough to separate this beach from another a grade away — a beach graded from thousands of samples at several stations is a firmer read. As more results are reported, the grade may shift.
In the most recent full reporting year, Spanish River was under a swimming advisory for about 0.3% of its monitored beach days — a useful gauge of how often problems recur here beyond any single sample.
