Introduction
Figure 1. Hawaii coastal counties with 2006 monitored beach data.
The BEACH Act of 2000 requires that coastal and Great Lakes states and territories report to EPA on beach monitoring and notification data for their coast recreation waters. The BEACH Act defines coastal recreation waters as the Great Lakes and coastal waters (including coastal estuaries) that states, territories, and authorized tribes officially recognize or designate for swimming, bathing, surfing, or similar activities in the water.
This fact sheet summarizes beach monitoring and notification data submitted to EPA by the state of Hawaii for the 2006 swimming season.
| County | Total Beaches | Monitored | Not Monitored |
|---|---|---|---|
| Hawaii | 103 | 21 | 82 |
| Honolulu | 141 | 67 | 74 |
| Kauai | 71 | 11 | 60 |
| Maui | 123 | 13 | 110 |
| Totals | 438 | 112 | 326 |
2006 Summary Results
How many beaches had notification actions?
Figure 2: Monitored beaches with and without notification actions in 2006.
When monitoring of water at beaches shows that levels of certain bacteria exceed standards, Hawaii's beach managers post a beach advisory, warning people of the possible risks of swimming, or formally notify the public that the beach is closed. Of the 112 coastal beaches that were monitored in 2006, 16, or 14 percent, had at least one advisory during the 2006 season (Figure 2).
How many notification actions were reported and how long were they?
Figure 3: Beach notification actions by duration.
A total of 17 beach notification actions were reported in the 2006 swimming season. Some actions were of relatively short duration, however 3 lasted longer than 30 days. Figure 3 presents breakdowns of action durations.
What percentage of days were beaches under a notification action?
Figure 4: Beach days with and without notification actions.
For Hawaii's 2006 swimming season, EPA determined there were a total of 40,880 beach days associated with the 112 monitored beaches. Actions were reported on 436 of those days or about 1 percent of the time (Figure 4).
How do 2006 results compare to previous years?
Beginning in 2003, states are required to submit data to EPA under the BEACH Act for beaches which are in coastal and Great Lakes waters. Table 2 compares 2006 data with data reported in previous years.
| Year | 2004 | 2005 | 2006 |
|---|---|---|---|
| Number of monitored beaches | 50 | 134 | 112 |
| Number of beaches affected by notification actions | 26 | 13 | 16 |
| Percentage of beaches affected by notification actions | 52% | 10% | 14% |
