The long view

The state has 973 tests on record for Stuart Causeway over 27 years, starting August 2000. In the last 10 years, 16 tests of 289 (6%) 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.
