Part 1. The Safe Drinking Water Act
Explain how environmental laws and regulations are made in the United States.
Once Congress passes an act, the text is standardized and published in the United States Code,
which is the official record of all federal laws. In order to make the laws work. Congress
authorizes certain government agencies, including EPA, to create regulations that specify what is
and is not legal.
The authorized agency proposes regulations that are subsequently listed in the Federal Register
so that the public can consider them and submit comments to the agency. The agency considers
all the comments, revises the regulation accordingly, and issues a final rule. Once a regulation is
completed and has been printed in the Federal Register as a final rule, it is "codified" by being
published in the Code of Federal Regulations (CFR), which is the official record of all
regulations created by the federal government. The CFR is divided into 50 volumes, called titles,
each of which focuses on a particular area. Nearly all environmental regulations appear in Title
40. The Safe Drinking Water Act is codified in 40 CFR 141 -143.
What is the Safe Drinking Water Act?
The Safe Drinking Water Act (SDWA), which celebrated its 25th anniversary in 1999, is the
main federal law that ensures the quality of Americans' drinking water. Under SDWA, EPA sets
standards for drinking water quality and oversees the states, tribes, localities, and water suppliers
who implement those standards.

Iii 1990. Congress amended the Safe Drinking Waier Act to emphasize sound science and risk-
based standard setting, small water supply system flexibility and technical assistance, small
system capability enhancements, capacity development, community-empowered source water
assessment and protection, public right-to-know. ant! water system infrastructure assistance
through a iriulti-hillion-dollar state revolving loan fund.

What kind of financial assistance (other than the from the public water system's
hosi organization) is available for federal facilities?
Unfortunately, lederal facilities are not authorized to receive additional funding for drinking
water system compliance under the SDWA. Tile SDWA. as amended in 1 996. established the
Drinking Water State Revolving Fund (DWSRF) to make funds available to non-federal drinking
water systems to finance infrastructure improvements. The program also emphasizes providing
funds to small and disadvantaged communities and to programs that encourage pollution
prevention as a tool for ensuring safe drinking water. Contact the public water system's host
organization (DoD, DoE. BLM. etc.) for financial issues.
Note: Federal Facilities are not authorized DWSRF allocations according to
federal law. The SDH.4 citation that prohibits the use of DWSRF funds for
Federally-owned systems is section 1452(a)(2). The USEPA reflects this
limitation in 40 CFR 35.3520(d).
How does the act apply to Federal Facilities?
Section 1447 of the SDWA, as amended in
1977, prov ides that, subject to a national
security exemption, each Federal Agency
shall be subject to. and comply with, ail
Federal. State, and local requirements, and
administrative authorities. To support this
change in prior policy the congressional
committee stated the following "...
Furthermore, the committee intends that
Federal agencies comply with State and
What does "'Primacy" mean?
"Primacy" refers to the agency nf the
state/tribe or federal government that has
primary enforcement responsibility (primacy)
with respect to the Safe Drinking Water Act.
The state or USHI'A Regional office usually
maintains primacy under the SDWA.
Currently, Wyoming is the only State that does
not have SDWA primacy.

local drinking water requirements ami regulations which arc mure stringent than liie primary
drinking water standards." A state with primacv does not have jurisdiction over Indian Lands
due lo the Indian land's status as "so\ereign nations." Therefore, the federal government has
jurisdiction over public water systems on Indian lands, unless the Indian Tribe obtains primaev,
On August {>. 1996. the Safe Drinking Water Aet (SDWA) Amendments of 1996. Public Law
Number 104-1 82 (the Amendments), became law. Prominent among the Amendments, are
several provisions uniquely applicable to federal entities. The new SDWA clarifies that federal
agencies eouhl be subject lo lines and penalties for a violation of an administrative order,
federal Facilities can be subject to lines and penalty orders issued by the F.PA or the stale. In
1998. the Army's Redstone Arsenal received a cash penalty of S80.000 and S807,000 in
supplemental env ironmental projects for improper management of a drinking water system that
served 22,000 people.
This guidance explains the Amendment's application to federal entities and offers advice to
regions when exercising the enhanced SDWA authorities. In hrief. the Amendments:
-significantly enhanced the SDWA's pre-existing waiver of.sovereign immunity,
-reiterated EPA's express enforcement authority over federal entities.
-streamlined the pre-existing statutory process for issuing public water system
compliance orders.
-expanded hPA's administrative penalty authority for any violation of the SDWA
including the public water supply and underground injection control requirements
and requirements imposed by an administrative order,
-provided citi/.ens the opportunity to obtain judicial rev iew of penalty orders,
-required states to use any penalty or line collected from a federal entity under Section
1447 for environmental purposes.

Is there guidance designed specifically for federal facilities to implement the Safe
Drinking Wafer Act and applicable executive orders?
Yes. Federal facilities may use sections of "The Yellow Book" to help them develop compliance
plans tor the SDWA (and other environmental regulations). The Yellow Book Guide to
Environmental Enforcement and Compliance at Federal Facilities has been written to meet the
needs of a diverse audience. The Yellow Book's primary purpose is to provide individuals with
Federal Facility environmental responsibilities with an informational tool to help comply with
environmental requirements and to clearly explain the compliance and enforcement processes
used by EPA and States at Federal Facilities. The Yellow Book was originally published in
Nov ember 1988. The revised and reissued Yellow Book, published in February 1999.

The SI) IVA constantly refers to a Public Water System. What is a Public Water
System?
Public water systems are the foundation of the drinking water program under SDWA. In
general, the SDWA and the L'SliPA define a public water system as one that serves water by
pipes or other constructed conveyances to at least 25 persons or 15 service connections lor at
least 60 days per year (see official definition below). Such water systems may be owned bv
homeowner associations, investor-owned water companies, local governments, and others.
Examples of federal Facility water systems include facilities like office buildings, housing areas,
recreational facilities, and bombing ranges that have drinking wafer systems that meet the
minimum requirements. Water that tines not come from a public water supply, and which serves
one or only a few homes, is called a private supply. Federal Facilities that are served drinking
water from another public water system should expect to receive public notices from their
prov ider only it deficiencies are identified during routine monitoring,
L'SEPA Official SDWA Definition: A public water system (PWS) is a system for the provision
to the public of water for human consumption through pipes or other constructed conveyances, if
such system has at least fifteen service connections or regularly serves at least twenty-five
indiv iduals daily—at least 60 days out of the vear.

Community water systems are public systems that serve people year-round in their residences.
LPA also regulates other kinds of public water systems—such as those at schools, factories,
campgrounds, or restaurants—that have their own water supply. Of the three types of PWS.
community water systems have the most requirements {monitoring, operator certification, etc.)
since CWS usually serve more consumers per system.
Non-Transient Non-Community Water System is a public water system that is no I a
community water system and regularly serves at least 25 of the same persons over 6 months per
-------
year. Typical monitoring requirements include periodic sampling for organics, inorganics, and
total coliforms.
Transient Non-Community Water System is a water system that is not a NTNCWS. This
system serves transient consumers. Transient consumers represent individuals who base the
opportunity, to consume water from a water system, hut who do not fit the definition of a
residential or regular consumer. Obvious examples are people stopping by at a highway rest
slop, people vacationing for a few days or weeks at a hotel or resort, people having lunch or
dinner at a restaurant, ete. Transient non-community water systems are typically required to only
monitor lor colitbrms, nitrate, and nitrite.

What are some key definitions I should krnnv before applying the SI) IIA at inv
facility?
Understanding the key legal definitions of the SDWA is very important for a successful
compliance program. Several important definitions are listed below;
Definitions
Determining
Constructed
Conveyances
W ater Suppliers'
Liability
Human Consumption, Defined to include drinking, bathing,
showering, cooking, dishwashing, and maintaining oral hygiene.
Constructed Conveyance. Broadly interpreted to refer to any manmade
conduit such as ditches, culverts, waterways. Humes, mine drains, or
canals.
Natural Waterways. Factors that a primacy agency should consider to
determine whether or not a natural waterwav is considered a
"constructed conveyance" include whether or not it exists in its current
configuration substantially from human modifications, who owns or
controls the water, and the reason why water is present.
Counting. Whether a "constructed conveyance" counts as a connection
depends on whether the water supplier knows or should know that the
connection exists or that the individuals are using the water from that
connection for human consumption.
A supplier cannot limit its SDWA liability by nut making efforts to
gather necessary information and documentation regarding its users'
water use, or solely by requiring its users to sign a waiver agreement.
Constructed
Conveyance
Exclusions
Other Than Residential Use Exclusion. A "constructed conveyance"
system may automatically exclude a connection from being counted if
its use is exclusively for purposes other than residential uses.
-------
Alternative Water Exclusion. A
"constructed conveyance'' system
may exclude a connection from
being counted if the primacy
agency makes a factual
determination based on
documentation submitted bv the
water supplier that the water
supplier is providing its users at
that connection with alternative
water that provides the equivalent
level of public health protection
as the applicable NPDWRs.
Treatment Exclusion. A "constructed conveyance" system may
exclude a connection from being counted if the primacy agency makes
a (actual determination based on documentation submitted by the water
supplier that the water al the connection is treated to provide the
equivalent level of public health protection as the applicable NPDWRs.
Special Irrigation II in existence prior to May 1 8. 1 ()94. and providing primarily
District	agricultural service with only incidental residential use. a piped
irrigation district may not be considered a PWS if all ofits connections
comply with the alternative water or treatment exclusions (abo\e) for
"constructed conveyance" suppliers.

it is important to remember that the USEPA does not regulate drinking water wells that	•
supply water to fewer than 25 people and have fewer than 15 service connect ions, but state	!
agencies may. Consult with local and state drinking water representatives for more
stringent requirements. Click on the links helow to locate your system's state drinking

It'iuil regulations apply to a PWS?
The Lnvironmental Protection Agency sets standards thai, when combined with protecting
ground water and surlace water, are a critical to ensuring safe drinking water. F.PA works with
its regional offices, states, tribes, and its many partners to protect public health through
implementing the Safe Drinking Water Act.
For a tabic of currently regulated contaminants, potential health effects, and sources, read
National Primary Drinking Water Standards, which lists the legally enforceable standards
( Maximum Contaminant Levels) thai apply to public water systems as well as National
Secondary Drinking Water Regulations, the non-enforceable guidelines for contaminants that

Part 2. Technical .Assistance
How Does Water Gel To a Consumer 's Faucet (Distribution System Issues)?
In a typical community water supply system, water is transported under pressure through a
distribution network of buried pipes. Smaller pipes, called service lines, arc attached to the main
water lines to bring water from the distribution network to your house. In many community
water supply systems, water pressure is provided by pumping water up into storage tanks that
store water at higher elevations than the houses they serve. The force of gravitv then "pushes"
the water into your home when you open your tap. Utilises on a private supply usuallv get their
water from a priv ate well. A pump brings the water out of the ground and into a small tank
within the home, where the water is stored under pressure. Water distribution system modeling
i.s important for ail water systems because low pressure within the distribution system can
drastically change the quality of water delivered to the system's consumers and must be
monitored closely. Low pressure (defined as below 20 psi) increases the potential for
contaminants to back-flow or back siphon into the water distribution system. Many states
require PWSs to maintain a minimum pressure of 20 psi in their distribution system because a
pressurized system ( -20 psi} is less likely to draw contamination into the distribution system
through pipe cracks or cross-connections.

What resources are available to federal facilities to perform water quality
modeling?
EPANET (see picture) is a Windows 95/98/NT program that performs extended period
simulation of hydraulic and water-quality behavior within pressurized pipe networks. A network
can consist of pipes, nodes (pipe junctions), pumps, valves and storage tanks or reservoirs.
EPANET tracks the flow of water in each
pipe, the pressure at each node, the height
of water in each tank, and the
concentration of a chemical species
throughout the network during a
simulation period pomprised of multiple
time steps. In addition to chemical
species, water age and source tracing can
also be simulated.
EPANET 2 Website:
http://www.epa.TOv/ORD/NRMRL/wswr
d/epanet.html#Description
The Windows version of EPANET
provides an integrated environment for
editing network input data, running
hydraulic and water quality simulations,
and viewing the results in a variety of
formats. These include color-coded
network maps, data tables, time series
graphs, and contour plots.
EPANET was developed by the Water Supply and Water Resources Division (formerly the
Drinking Water Research Division) of the U.S. Environmental Protection Agency's National
Risk Management Research Laboratory. It is public domain software that may be freely copied

Another good water distribution system modeling site is maintained by the University of
Kentucky. Engineers at the University of Kentucky and their associates have been developing
and supporting state-of-the-art pipe network modeling technology for over 30 years. A number
of technical achievements and teaching awards have been presented to members of the
development team in recognition of this work that has set the world standard for pipe network
technology.
The P1PE2000 graphical user interface (GUI) incorporates all the best existing modeling
capabilities and introduces a number of powerful new ones. This advanced WINDOWS (95. 98,
NT4, NTS) GUI will allow access to steady state, transient, gas, and steam models for a variety
of applications. 1 he PIPE2000 GUI incorporates powerful mapping and comprehensive facilities
management capabilities (AM/FM). The PIPE2000 development effort combined a high level of
hydraulic expertise for model development and advanced computer-engineering design of the
graphical interface. This is the only way to produce the powerful modeling tools needed by
today's engineers. Choose your modeling tools only after you have taken a comprehensive look

What resources are available to federal facilities to learn how to conduct
appropriate operations and maintenance projects on a public water system?
MIL-HDBK-! 164 provides general technical guidance for operating and maintaining (see
picture) potable water systems at fixed military installations (and other federal facilities). Since
no two installations are exactly alike, this handbook is supplemental to site-specific operations
and maintenance (O&M) manuals provided for each installation. The handbook applies to all
personnel responsible for operating and maintaining fixed-base water systems, including
supervisors as well as
operators. To provide military
personnel with the most up-to-
date information available the
handbook guides the reader to
industry standards, manuals of
practice, training guides,
handbooks, and miscellaneous
documents published by the
American Water Works
Association (AWWA) and
other authorities in the water

Are federal facility public water systems required to conserve drinking water?
Yes. Executive Order 13123 mandated the establishment of water conservation goals (eg.
identify conservation opportunities and install cost-effective water-conserving fixtures
equipment) for Federal Agencies. The Department of Energy (DOE) was tasked to take the lead
in this effort, with inputs from the Military Services and other Federal Agencies. The products
of the effort are listed below.

How can water systems control
cross-connections ?
Contamination can enter a water
system in many ways, usually through
some type of opening to the
distribution system (i.e. cracked pipe,
damaged reservoir hatch, etc.). One
common route is through cross-
connections. Cross-connections are
conditions that allow contaminated
water to mix with potable water.
14
-------
Cross-connections can happen it an individual begins filling a livestock water lank by placing a	|
garden hose inside the tank timing filling. II water pressure is lost while the tank is tilling. dirl\	I
w ater trum the livestock tank could flow backwards through the garden hose into the drinking
water system. Similar situations occur when Filing pesticide spravers, fertilizer tanks, elc.
Cross-connections control programs arc mandated by the SDWA and should be eliminated or
protected using back flow devices (see inset picture above) and routine surveillance prourams	(

Several websites provided cross-connection and backflow guidance. The Foundation for Cross-	j

What actions should the water system take during an emergency, natural disaster,	i
or known waterborne disease outbreak?	|
Safety should be the first priorit)' of any water system during emergencies or natural disasters	|
(floods, tornado, etc.). Preventing contamination to the drinking water system is the next most
important. If contamination is suspected, contact your system's primacy agency. The following
guidance clarities how long to boil water during a boil water advisory or other drinking water
emergency. This guidance was prompted by the fact that various agencies have issued
inconsistent instructions on the duration of boiling.

How do Public Water Suppliers treat my water to make it safe (Treatment Issues)?
Water suppliers use a variety of treatment processes to remove contaminants from drinking
water. These individual processes may be arranged in a "treatment train" to remove undesirable
contaminants from the water. The most commonly used processes for surface water plants (and
possibly even plants using groundwater under
the direct influence of surface water) include
filtration, flocculation and sedimentation, and
disinfection. Some treatment trains also include
ion exchange and adsorption. A typical water
treatment plant would have only the
combination of processes needed to treat the
contaminants in the source water used by the
facility. Most groundwater facilities usually do
very little treatment, primarily only disinfecting
the water. The EPA is responsible for
identifying "Best Available Treatment
Technologies" (BATs) for every regulated
contaminant. Some BATs are listed below. If
you want to know what types of treatment are
used for your water supply, contact your local
water supplier or public works department.
Flocculation/Sedimentation
Flocculation refers to water treatment processes
that combine small particles into larger
particles, which settle out of the water as
sediment. Alum and iron salts or synthetic organic polymers (alone, or in combination with metal
salts) are generally used to promote coagulation. Settling or sedimentation is simply a gravity
process that removes flocculated particles from the water.
Filtration
Many water treatment facilities use filtration to remove remaining particles from the water
supply. Those particles include clays and silts, natural organic matter, preeipitants from other
treatment processes in the facility, iron and manganese, and microorganisms. Filtration clarifies
water and enhances the effectiveness of disinfection.
Ion Exchange
Ion exchange processes are used to remove inorganic constituents if they cannot be removed
adequately by filtration or sedimentation. Ion exchange can be used to treat hard water (i.e. water
which contains divalent cations like calcium and magnesium). It can also be used to remove
arsenic, chromium, excess fluoride, nitrates, radium, and uranium.
16
-------
Adsorption
Organic contaminants, color, ami taste- and odor-causing compounds can stick to the surface of
granular or powdered activated carbon (GAC or PAC). GAC is generally more effective than
PAC in removing these contaminants. Adsorption is not commonly used in public water
supplies.
Disinfection (chlorination, ozonation, ( 1, etc.)
Water is often disinfected before it enters the distribution system to ensure that dangerous
microbes are killed and is mandatory for SW and GWL'DISW systems. Chlorine, chloramines.
or chlorine dioxide most often are used because they arc very eifectivc disinfectants, and residual
concentrations can be maintained to guard against biological contamination in the water
distribution system. Ozone and IIV are powerful disinfectants, but arc not effective in
controlling biological contaminants in the distribution pipes because they do not leave anv
residual disinfectant in the treated water. Water systems that use ozone or LJV could become
contaminated after the disinfection point (i.e. in the distribution system} because there is no
residual..

1 he Lnvironmental Protection Agency (U.S. EPA) is responsible for ensuring that Federal
Facilities and organizations comply with federal laws that protect the public health and the
en\ iromnent. U.S. EPA's Office of Enforcement and Compliance Assurance {OFC'A) has begun
combining traditional enforcement activities with more innovative compliance approaches
including the provision of compliance assistance to the general public. U.S. FPA's Office of
C omplianee Assistance was established in 1CJ94 to locus on compliance assistance-related
activities. U.S. FPA is also encouraging the development of self-assessment programs at
individual facilities. Voluntary audit programs play an important role in helping companies meet
their obligation to comply with environmental requirements. Such assessments can be a critical
link, not only to improved compliance, but also to improvements in other aspects of an
organization s performance, f or example, environmental audits may identify pollution
prevention opportunities that can substantially reduce an organization's operating costs.
Environmental audits can also serve as an important diagnostic tool in evaluating a facility's
overall environmental management system or EMS.
USEPA is developing 13 multi-media Environmental Audit Protocols to assist and encourage
federal Facilities and organizations to perform environmental audits and disclose violations in
accordance with OECA's Audit and Small Business Policies. The audit protocols are also
intended to promote consistency among regulated entities when conducting environmental audits
and to ensure that audits are conducted in a thorough and comprehensive manner.
U.S. EPA has developed these audit protocols to provide regulated entities with specific
guidance in periodically evaluating their compliance with federal environmental requirements.
The Audit Protocols are designed for use by individuals who arc already familiar with the federal
regulations but require an updated comprehensive regulatory checklist to conduct environmental
compliance audits at regulated facilities. Typically, compliance audits are performed by persons
who are not necessarily media or legal experts but instead possess a working knowledge of the
regulations and a familiarity with the operations and practices of the facility to be audited. These
two basic skills are a prerequisite for adequately identifying areas at the facility subject to
environmental regulations and potential regulatory violations that subtract from the organizations
environmental performance. With these basic skills, audits can be successfully conducted by
24
-------
persons with \arious educational backgrounds (e.g.. engineers, scientists, lawyers, business
owners or operators). These protocols ore not intended to he a substitute for the regulations nor
arc (hey intended to he instructional to an audience seeking a primer on the requirements under
I'itlc 40. however, they are designed to he sufficiently detailed to support the auditor's efforts.

i his document summarizes the results of an ongoing project to evaluate the effectiveness
of the C omposite Correction Program approach to improving the performance of drinking
water treatment facilities. 1 his approach is a logical and systematic evaluation of a water
treatment facility. It is made by a team with knowledge of drinking water treatment plant
design, operation, and operational trouble shooting in order to identify the unique
combination of factors limiting performance. The facility's capacity, operational
performance, maintenance program, and administration are among the factors
investigated.
Once the significant elements affecting a plant's performance have been identified, a
program may be initiated to address these findings and thus assist the community in using
its existing major unit processes to achieve the desired finished water quality.
The results oi the 1 3 drinking water plant evaluations done to date are summarized, as are
two corrective action programs. The ease studies focus on the potential for the approach
to improve the performance of small systems in meeting the turbidity removal

systems. A comprehensiv e sanitary survey is an important element in helping water
systems protect public health. Sanitary surveys are carried out to evaluate: (1) the
capability of a drinking water system to consistently and reliably deliver an adequate
quality and quantity of safe drinking water to the consumer, and (2) the system's
compliance with Jederai drinking water regulations. Much of the information generated
by a sanitary survey helps identify existing and potential sanitary risks. This guidance
manual will identify assessment criteria to be evaluated for sanitary risks. The manual
also describes how to identify significant deficiencies that represent an imminent health
risk and require immediate correction.
