              Wisconsin  2011  Swimming  Season
              August 2012
                      EPA820-F-12-025
  Introduction
  The Beaches Environmental Assessment and
  Coastal Health (BEACH) Act of 2000 authorizes
  EPA to provide grants to coastal and Great Lakes
  states, territories, and eligible tribes to monitor
  their coastal beaches for bacteria that indicate the
  possible presence of disease-causing pathogens
  and to notify the public when there is a potential
  risk to public health. The BEACH Act requires that
  recipients of those grants report their coastal beach
  monitoring and notification data to EPA. This fact
  sheet highlights the data submitted to EPA by the
  State of Wisconsin for the 2011 swimming season.


  2011 Swimming Season
  Monitoring and Notification
  Actions
  Wisconsin monitored 116 coastal beaches in
  thirteen counties during the 2011 swimming
  season (Figure 1 and Table 1). When monitoring
  results at swimming beaches show that levels of
  specific indicator bacteria in the water exceed
  applicable water quality standards, Wisconsin
  officials issue a beach advisory, warning people
  of possible risks of swimming or close the beach
  to public swimming until further monitoring
  finds that water quality complies with applicable
  standards. In some cases, advisories and closings
  are issued preemptively (i.e., without having actual
  bacteria monitoring results) due to storms or other
  conditions that might affect swimmer safety.

            actions in 2011
How many beaches had notification actions?
In 2011, of the 116 coastal beaches that Wisconsin
monitored, 86 (74 percent) had at least one
notification action (Figure 2). This is approximately
the same as in most previous years with the
exception of 2009.

How many notification actions were issued and
how long did they last?
Wisconsin issued 438 notification actions during
the 2011 swimming season. Typically Wisconsin
lifts an action when follow-up monitoring indicates
that water quality complies with applicable
standards. For the majority of actions (92 percent)
water quality returned to normal and beaches were
deemed safe for swimming within one or two days
(Figure 3).

What percentage of days were beaches under
a notification action?
EPA calculates the total available beach days and
the number of beach days with notification actions
                                                        2011

to better track trends over time. Total available
beach days are determined by multiplying the
length of the beach season by the number of
beaches in the state. For 2011 EPA calculated
that 10,710 beach days were associated with the
swimming seasons of the 116 monitored Wisconsin
beaches. Wisconsin reported notification actions
on 601 days, meaning that beaches were open
and safe for swimming about 94 percent of the
time. This continues the trend of consistently high
percentages of open beach days at state beaches
(Figure 4).
