               2012  Swimming Season
               June 2013
EPA820-F-13-014
               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, and that EPA maintain an
               electronic database of that data, accessible to the public, so that they can make informed
               choices about where to swim. To support reducing the risk of exposure to disease-
               causing pathogens at recreational beaches, EPA is posting the latest data submitted to
               EPA about beach closings and advisories for the 2012 swimming season. This fact sheet
               also highlights recent developments in EPA's beach program.

2012 Swimming Season  Results
When monitoring results at swimming beaches
show that levels of specific indicator bacteria
in the water exceed applicable water quality
standards, states, territories, and tribes 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.
Some states and local agencies, in addition to
water sampling, use models or other predictive
tools as a basis for issuing notification actions at
beaches.

How many beaches had notification actions?
In 2012 of the 3,762 coastal beaches that were
monitored (Figure 1),  1,504 (40 percent) had at
least one advisory or closure (Figure 2). This
is about a 3 percent decrease from the 2011
swimming season. One reason for the decrease
was that Hawaii did not issue as many rainfall-
based advisories in 2012 as they did in 2011 (72 in
2012, 264 in 2011). In addition, New York and
Connecticut issued fewer advisories as compared
to 2011, the year of Hurricane Irene's landfall.

How many notification actions were issued
and how long did they last?
A total of 5,725 notification actions (i.e., advisories
or closings) were issued by states, territories,
and tribes during the 2012 swimming season.
Typically an action is  lifted when follow-up
monitoring proves that water quality complies
with applicable standards. For the majority of
cases in 2012 (66 percent) water quality returned
to normal and beaches were deemed safe for
swimming within one or two days (Figure 3).
Only rarely (13 percent) did notification actions
last more than a week.

What percentage of days were beaches under
a notification action?
EPA calculates the total available beach days
and the number of beach days with advisories
or closings to better track trends over time. To
calculate total available beach days, we multiply
the length of each state's  and territory's beach
season by the number of  beaches in the state  or
territory. For 2012 EPA determined that 695,527
beach days were associated with the swimming
seasons of 3,762 monitored beaches. Notification
actions were reported on 31,163 days, meaning
that beaches were under an advisory or closed
about 4.5 percent of the time, consistent with the
past several years (Figure 4).

Protecting your local beaches
Beach advisories and closings can result from a
number of sources: overflows from sewer systems,
either by design or due to blockages; treatment
plant malfunctions; stormwater runoff after
rainfall; waste from boats; leaking septic systems;
or pet and wildlife waste. To help minimize the
risk to beachgoers, EPA is helping communities
build and properly operate sewage treatment
plants, working to control overflows to reduce
them as much as possible, and working with the
U.S.  Coast Guard to reduce discharges from boats
and larger ships. To find out more about what you

                                     Beach Program

                                     EPA Improved Access to Online Beach
                                     Monitoring and Notification Data (BEACON)
                                     Clean Water Act section 406(e) requires EPA to
                                     make available a national database that contains
                                     state reported beach monitoring and notification
                                     data. In 2003 EPA created the BEACON (BEach
                                     Advisory and Closing Online Notification) system
                                     to meet the Agency's BEACH Act requirements.
                                     EPA upgraded the BEACON system in 2012 to use
                                     state-of-the-art map navigation and report display
                                     tools. Maps are dynamically produced and show
                                     the location of more than 6,000 beaches and the
                                     related water quality monitoring stations on road
                                     or satellite base maps. Reports can combine both
                                     notification data and water quality monitoring
                                     data, and new state data can be displayed every

                                     2072 Recreational Water Quality Criteria
                                     EPA has released its final 2012 Recreational Water
                                     Quality Criteria. The Agency's new criteria reflect
                                     the latest scientific knowledge, public comments,
                                     and external peer review. They are designed to
                                     protect the public from exposure to harmful levels
                                     of pathogens while participating in water-contact
                                     activities such as swimming, wading, and surfing
                                     in all waters designated for such recreational uses.
                                     For more information about the criteria, including
                                     the research EPA conducted, visit: http://water.

National List of Beaches
EPA updated and improved the National List of
Beaches on its website. The BEACH Act requires
EPA to periodically identify and publish a list
of discrete coastal recreation waters adjacent to
beaches or similar points of access that are used
by the public. The Agency must also identify
whether there is a monitoring and notification
program for each beach.
EPA first published the National List of Beaches in
2004,  with updates in 2008 and 2010. The National
List of Beaches contains beaches identified by the
states, tribes and territories ("state") under the
BEACH Act in U.S. coastal and Great Lake waters.
The list does not include beaches on inland waters
because they are not subject to the BEACH Act.
The National Lists of Beaches for the 2004, 2008,
and 2010 swimming seasons are static pdf files,
organized by state and county. For some territories
and Hawaii, the beaches are listed by island.
Alaska's beaches are reported by community.
Beach names are listed with their monitoring
status for the selected swimming season.
The improved list is available in a dynamic
format that links to EPA's Beach Advisory and
Closing On-line Notification (BEACON) system
where further details about each beach can
also be found. The list contains the most recent
information reported to EPA by coastal and
Great Lakes states and can be found at:
