a
States with marine beaches not included in this analysis have management criteria that differ from the four standard types listed (rainfall advisories, different enterococci levels, ankle-depth sampling, etc.)
b
The sample on Day 3 was lost and therefore affected consecutive measurements for Days 2-3 and Days 3-4. Only 9 samples were available for this hour.
c
The sample on Day 5 was not collected due to a storm.
