The long view

The state has 498 tests on record for Gulfstream over 25 years, starting August 2002. In the last 10 years, 1 test of 20 (5%) came back Poor, close to 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.
