               Grand  Portage  2011  Swimming  Season
               October 2012
                       EPA820-F-12-050
  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
  Grand Portage Band of the Chippewa for the 2011
  swimming season.


  2011 Swimming Season
  Monitoring and Notification
  Actions
  The Grand Portage Band monitored 11 coastal
  beaches 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, Grand Portage Band
  officials issue a beach advisory,  warning people of
  possible risks of swimming.

  How many beaches had notification actions?
  In 2011, of the 11 coastal beaches that the Grand
  Portage Band monitored, 6 (54 percent) had at least
  one notification action (Figure 2). The increase in
  the number of beaches and action days in 2011
  compared to the two previous years is directly due
  to a severe storm in June that resulted in a federal
  disaster area declaration for 13 Minnesota counties
  and three tribal areas, including the Grand Portage
  Band tribal reservation. Besides the June event

the Grand Portage Band reported only one other
notification action at one beach for the rest of the
swimming season.

How many notification actions were issued and
how long did they last?
The Grand Portage Band issued six notification
actions during the 2011 swimming season. The
Grand Portage Band lifts an action when follow-up
monitoring indicates that water quality complies
with applicable standards. In all cases water quality
returned to normal and beaches were deemed safe
for swimming within a week (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

            and safe for swimming

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 1,331 beach days were associated with the
swimming seasons of the 11 monitored Grand
Portage Band beaches. The Grand Portage Band
reported notification actions on 42 days, meaning
that beaches were open and safe for swimming
about 97 percent of the time. This continues the
trend of consistently high percentages of open
beach days (Figure 4).
