The long view

The state has 1,292 tests on record for Davis Island Beach over 27 years, starting July 2000. In the last 10 years, 48 tests of 476 (10%) came back Poor, above the rate for all Florida sampled beaches (6.1%). Bacteria levels usually jump after heavy rain, when stormwater washes to the shore, and drop again within a day or two.
