Introduction

In 1997, the U.S. Environmental Protection Agency established the Beaches Environmental
Assessment, and Coastal and Health (BEACH) Program.  The goal of the BEACH program is to
reduce risks to human health caused by exposure to pathogens in recreational waters.  Surveys
and ongoing scientific studies continue to document the presence of, or the potential for, disease-
carrying bacteria, viruses, and other pathogens present in local beach water, primarily from
sewage and stormwater runoff.  Humans can be exposed to pathogens in recreational waters
through ingestion, inhalation, and body contact.

The BEACH Program focuses on the following five areas to improve public health and
environmental protection programs for beach goers, and to provide the public with information
about the quality of their beach  water:

              Strengthening beach standards and testing
              Providing faster  laboratory test methods
              Predicting pollution
              Investing in health and methods  research
              Informing the public

The Beaches Environmental Assessment and Coastal Health (BEACH) Act of 2000 authorized
EPA to award grants for development and implementation of programs to notify the public of the
potential exposure to disease-causing microorganisms in coastal recreation waters. Program
development and implementation grants to eligible States, Territories, Tribes, and local
governments support microbiological testing and monitoring of coastal recreation waters,
including the Great Lakes, that  are adjacent to beaches or similar points of access used by the
public. The BEACH Act also amended Section 303 of the Clean Water Act to require by April
10,2004 that coastal and Great  Lakes states adopt EPA's published indicators for pathogens
with criteria as protective as those published by EPA, in their water quality standards.

EPA is working with states and tribes to assist them in adopting water quality criteria for EPA's
published pathogen indicators, E. coli and/or enterococcus bacteria, in their water quality
standards. The Agency is also working with states, tribes, and local governments to strengthen
local beach health monitoring efforts and procedures to achieve these standards.  EPA assistance
includes awarding grants for beach monitoring  and public notification as well as providing
technical assistance and training.

This document, Bacterial Water Quality Standards for Recreational Waters (Freshwater and
Marine Waters) - Status Report provides a brief overview of the bacterial water quality standards
that have been adopted by states for their marine and fresh recreational  waters in the United
States. This report is based on consultations with EPA water quality standards coordinators.
The report is accurate as of September 2002; however, there may be revisions to standards that
are not reflected in this report.  EPA will update the report periodically  to reflect new
information. The information in the report is presented in summary format for both
states/territories and tribes. The summary is organized first by EPA region, and then by state,
territory, and tribe within each region.

-------
For the precise regulatory language applicable to a particular state, the reader should consult the
water quality standards of the state.  Copies of state water quality standards may be obtained
from the state's water quality management agency or its equivalent (EPA houses a repository of
state, tribal, and territorial water quality standards on its website at
http://www.epa.gov/waterscience/standards/wqslibrary/). Readers should also note that
standards in this report may not be the only guidelines or standards in effect for recreational
waters in a particular location. It is not uncommon for local health agencies to develop and
adopt site-specific guidelines as part of their public health codes. One should consult the
appropriate local health agency to obtain detailed information.

EPA's BEACH Program is improving public access to information about the quality of the water
at their beaches and health risks associated with swimming in those waters. More information
about water quality at our nation's beaches, local protection programs, and other beach-related
programs is available on EPA's "Beach Watch" internet website at
http://www.epa.gov/waterscience/beaches/.

-------
Water Quality Standards Background

In response to widespread public concern about the condition of our nation's waters, the United
States Congress enacted landmark legislation in 1972. This statute, the Federal Water Pollution
Control Act Amendments of 1972 (referred to as the Clean Water Act of 1972, or CWA),
expanded and built upon existing laws designed to control and prevent water pollution.
Successive amendments to the 1972 CWA (the Clean Water Act of 1977 and the Water Quality
Act of 1987) have continued to strengthen the law to better protect our nation's waters.

Water quality standards are the cornerstone of a state's water quality management program.
States, territories, and Indian tribes set water quality standards for waters within their
jurisdictions.  Water quality standards define a use for a waterbody and describe the specific
water quality criteria to achieve that use. The water quality standards also contain
antidegradation policies to protect existing water quality. These are the goals by which success
is ultimately gauged for a given waterbody or watershed.

The water quality standards program is administered by the U.S. Environmental Protection
Agency (EPA). Congress has mandated that EPA is responsible for providing water quality
criteria recommendations; approving state-adopted standards for waters of the United States;
evaluating adherence to the standards; and overseeing enforcement of standards  compliance.
Guidance for the development of standards by individual states, tribes, and territories is
contained in the EPA documents Water Quality Standards Handbook, Second Edition (1983)
and Ambient Water  Quality Criteria for Bacteria (1986).

Fecal bacteria have  been used as an indicator  of the possible presence of pathogens in surface
waters and the risk of disease, based on epidemiological evidence of gastrointestinal disorders
from ingestion of contaminated surface water or raw shellfish. Contact with contaminated water
can lead to ear or skin infections, and inhalation of contaminated water can cause respiratory
diseases. The pathogens responsible for these diseases can be bacteria, viruses, protozoans,
fungi, or parasites that live in the gastrointestinal tract and are shed in the feces of warm-blooded
animals.

However, because of the difficulties in analyzing for and detecting the many possible pathogens
or parasites, concentrations of fecal bacteria, including fecal conforms, enterococci, and
Escherichia coli, are used as the primary indicators of fecal contamination.  The latter two
indicators are considered to have a higher degree of association with outbreaks of certain
diseases than fecal coliforms and were recommended as the basis for bacterial water quality
standards in the 1986 Ambient Water Quality  Criteria for Bacteria document (both for fresh
waters, enterococci  for marine waters).  The standards are defined as a concentration of the
indicator above which the health risk from waterborne disease is unacceptably high.

Prior to the 1986 revision to the National criterion, there were recommendations in the report of
the National Technical Advisory Committee to the Secretary of the Interior, Water Quality
Criteria (1967) and  by EPA in Quality Criteria for Water (1976).  Both of these documents were
based on fecal coliforms and recommended that maximum densities not exceed geometric means
of 200 organisms per 100 ml in recreational waters.

-------
The 1986 criteria statement for bacteriological criteria follows:

                          EPA Criteria for Bathing (Full Body Contact)
                                      Recreational Waters
Freshwater

       Based on a statistically sufficient number of samples (generally not less than 5 samples equally
spaced over a 30-day period), the geometric mean of the indicated bacterial densities should not exceed
one or the other of the following:'

                      £ co/i         126 per 100 ml; or
                      Enterococci    33 per 100 ml.

No sample should exceed a one sided confidence limit (C.L.) calculated using the following as guidance:

                      Designated bathing beach 75% C.L.
                      Moderate use for bathing 82% C.L.
                      Light use for bathing 90% C.L.
                      Infrequent use for bathing 95% C.L.

based on a site-specific log standard deviation, or if site data are insufficient to establish a log standard
deviation, then using 0.4 as the log standard deviation for both indicators.
Marine Water

Based on a statistically sufficient number of samples (generally not less than 5 samples equally spaced
over a 30-day period), the geometric mean of the enterococci densities should not exceed 35 per 100 ml.

No sample should exceed a one sided confidence limit using the following as guidance:
                      Designated bathing beach 75% C.L.
                      Moderate use for bathing  82% C.L.
                      Light use for bathing  90% C.L.
                      Infrequent use for bathing 95% C.L.

based on a site-specific log standard deviation, or if site data are insufficient to establish a log standard
deviation, then using 0.7 as the log standard deviation.
        'Only one indicator should be used.  The regulatory agency should select the appropriate
indicator for its conditions.

1 FC = fecal coliforms; TC = total coliforms; EN = enterococci; EC = Escherichia coli.
1 Many jurisdictions use both the 1986 indicator criteria and fecal coliforms; some continue to use total coliforms.
3 California has 9 Regional Boards; some use the 1986 indicator criteria, whereas some use fecal eoliform and total coliform entirely or for other purposes.

methodology. FC bacteria can be used as an alternative instream indicator of
recreational suitability until sufficient data are available for EC or EN. For
segments designated as oyster waters, FC can continue to be used as an
indicator of recreational suitability because FC is used as the indicator for
suitability of oyster water use.

           Comments:          Colorado has two categories of primary contact recreation use in addition to
                               their secondary contact recreation use. The Recreation Class 1 a use is the
                               default use category. In these waters, primary contact recreation uses have been
                               documented or are presumed to be present. The Recreation Class Ib use is
                               intended to protect waters with the potential to support primary contact uses,
                               and may be assigned only if a reasonable level of inquiry has failed to identify
                               any existing primary contact recreation uses of the waterbody.  The Rec Ib use
                               category is assigned geometric mean E. coli criteria based on an illness rate of
                               10 per 1000 swimmers (compared to 8 per 1000 for Class la). Finally, the
                               Recreation Class 2 use may be assigned only where a use attainability analysis
                               has demonstrated that there is no reasonable potential for primary contact
                               recreation uses to occur within the next 20-year period.

          Comments;
                 No more than 1 sample, or 10% of the samples if there are
                 more than 10 samples, may exceed 200 FC and 400 FC for
                 both freshwater  and  marine, primary  and secondary,
                 respectively.

Alaska designates all waters for all uses, and the most stringent criteria must be
used. Therefore, for freshwater, the drinking water use criterion of 20 FC usually
drives most NPDES permit actions, 303(d) listings, and TMDL development. For
marine waters, the most stringent bacterial criterion is for the seafood processing
use - 20 FC (no more than 10% of the samples may exceed 40 FC). Even though
Alaska has 100 FC/200 FC as its recreation criteria, more stringent criteria for other
use categories take precedence.
