EPA's BEACH Report:
Indiana 2010 Swimming Season
May 2011
Introduction
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 coastal 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 Indiana for the 2010 swimming
season.

2010 Summary Results
How many beaches had notification actions?
When water quality standards are exceeded at a
particular beach, Indiana requires beach managers
to post an advisory or closure. An advisory warns
people that there is an increased health risk associated
with entering the water and a closure warns people
to completely avoid contact with the water. All
24 monitored beaches had at least one advisory issued
during the 2010 swimming season. About 80 percent
of Indiana's notification actions lasted one day or less.
Figure 2 presents a full breakdown of notification
actions.
What percentage of days were beaches under a
notification action?
In 2010, about 18 percent of Indiana's total beach days
were under an advisory or closing (Figure 3).
How do 2010 results compare to previous years?
Table 2 compares 2010 notification action data with
monitored beach data from previous years.
What pollution sources possibly affect investigated
monitored beaches?
Indiana's beaches were not investigated for possible
pollution sources in 2010.
