Program Overview

The Water Security (WS) initiative is a U.S. Environmental Protection Agency (EPA) program that addresses the risk of
contamination of drinking water distribution systems. EPA established this initiative in response to Homeland Security
Presidential Directive 9, under which the Agency must "develop robust, comprehensive, and fully coordinated surveillance
and monitoring systems, including international information, for... water quality that provides early detection and awareness
of disease, pest, or poisonous agents."
EPA is implementing the WS initiative in three phases:

Phase I: Develop the conceptual design of a contamination warning
system for timely detection and appropriate response to drinking
water contamination incidents to mitigate public health and economic
impacts;

Phase II: Test and demonstrate contamination warning systems
through pilots at drinking water utilities and municipalities and make
refinements to the design as needed based upon pilot results; and

Phase III: Develop practical guidance and outreach to promote
voluntary national adoption of effective and sustainable drinking
water contamination warning systems.

Figure 1 below shows EPA's approach to developing the WS
initiative.

Phase I: Develop a Conceptual Design

A WS contamination warning system (CWS) involves
the deployment of multiple monitoring and surveillance
components to achieve timely detection of possible
contamination in drinking water distribution systems.
   The objectives forEPA's recommended CWS design
   include:
   • Detect a broad spectrum of contaminant classes;
   • Achieve spatial coverage of the entire distribution
     system;
   • Detect contamination in sufficient time for effective
     response;
   • Maintain operational reliability;
   • Minimize the false positive rate; and
   • Provide a sustainable architecture for day-to-day
     monitoring of distribution system water quality.
As illustrated in Figure 2, there are two major operational
phases associated with a multi-component CWS: Routine
Monitoring and Surveillance and Consequence Management.
The day-to-day operation of the five monitoring and
surveillance components of a CWS include:

• Online water quality monitoring comprises stations
  located throughout the distribution system that measure
  chlorine, total organic carbon, conductivity, and other
  parameters. Software analyzes the monitoring data to
  establish baseline parameter levels. Possible contamination
  is indicated when a significant deviation from a baseline
  occurs.

• Public health surveillance involves the analysis of health-
  related data to identify disease events that may stem from
  drinking water contamination. Public health data may
   include over the counter drug sales, hospital admission
   reports, infectious disease surveillance, Emergency
   Medical Services (EMS) reports, 911 calls, and poison
   control center calls.

 •  Sampling and analysis is the collection of distribution
   system samples that are analyzed for classes of
   contaminants, as well as specific contaminants. Sampling
   is both routine, to establish a baseline, and triggered, to
   respond to an indication of possible contamination from
   another component.  Analyses are conducted for chemicals.
   radionuclides, pathogens, and toxins using a laboratory
   network.

 •  Enhanced security  monitoring includes the equipment
   and procedures that detect and respond to security
   breaches at distribution system facilities. Security
   equipment may be cameras, motion sensing lights, door
   contacts, ladder and window motion detectors, and access
   hatch detectors.

 •  Customer complaint surveillance enhances the collection
   and automates the analysis of calls by customers  for water
   quality problems indicative of possible contamination.
   Customers may detect contaminants with characteristics
   that impart an odor, taste, or visual change to the drinking
   water.

 Routine monitoring and surveillance, along with event
 detection and initial trigger validation, determine if
 contamination is possible. Consequence management is
 the second major operational phase of a CWS and provides
 a decision-making framework used to establish credibility.

 economic impacts, and ultimately return the system to
 normal operations.

 Phase II: Test and Demonstrate

Greater Cincinnati Water Works Pilot Project
EPA deployed the first full-scale, comprehensive CWS
pilot in partnership with the City of Cincinnati at the
Greater Cincinnati Water Works (GCWW). Planning and
pre-design activities for the pilot began in December
2005, were substantially completed in June 2009, and data
collection concluded in June 2010. The drinking water CWS
components are fully operational, with performance data
continuing to be evaluated by EPA.

Elements of each Cincinnati CWS component, as installed,
are noted below, and are described more fully in the report
Cincinnati Pilot Post-Implementation System Status, (EPA-
817-R-08-004), available atwater.epa.gov/infrastructure/
watersecurity/index.cfm.

Water Quality Monitoring
• Installed a network of 17 water quality monitoring stations
  with capability to measure a variety of water quality
  parameters;
• Installed a dedicated communication network and
  Supervisory  Control and Data Acquisition (SCADA)
  system; and
• Deployed two water quality event detection systems.

Sampling and Analysis
• Established a local laboratory network to support analysis
  of routine and triggered samples for priority contaminant
  classes;
• Implemented a baseline monitoring program to
  characterize background contaminant occurrence; and
• Developed specialized field and laboratory procedures for
  incident response sampling and analysis.

Enhanced Security Monitoring
• Installed video cameras, motion sensors, and door contact
  switches at three large pump stations and ladder motion
  sensors at seven elevated storage tanks; and
• Leveraged existing partnerships with local law
  enforcement agencies to support the investigation of
  security breaches.

Customer Complaint Surveillance
• Enhanced the interactive voice response system that greets
  all callers to  include a category for water quality issues;
  and
• Deployed event detection systems to continually analyze
  data from the interactive voice response and work order
  systems to detect anomalies that might be indicative of
  contamination.
Public Health Surveillance
• Deployed systems to capture new data streams, specifically
  911 calls and emergency medical service data applicable to
  drinking water exposure;
• Established a Public Health User's Group with local
  partners and GCWW personnel; and
• Implemented automated email notification to notify all
  partners when a potential water-related health anomaly is
  detected.

Consequence Management
• Developed a Consequence Management Plan to serve as a
  response guide, and a Crisis Communication Plan to guide
  public notification and risk communication procedures
  during all phases of a potential contamination incident; and

• Coordinated a training and exercise program for utility
  staff and local response partner agencies to test, evaluate,
  and train participants on CWS plans and procedures.

The use of multiple monitoring and surveillance components
is expected to provide broad contaminant coverage
throughout the core GCWW retail service area, reduce the
time for initial contaminant detection, and improve the
reliability of information generated by the system. Further,
the integration of monitoring and surveillance systems with
routine operations provides many opportunities for dual-
use benefits (e.g., improved water quality management and
customer service).

Evaluation of the Cincinnati pilot will quantify system
performance, derive lessons learned, and assess the cost/
benefit of deploying CWSs at drinking water utilities. This
information, along with data gathered from other pilots, will
be critical in the development of effective and sustainable
CWS guidance for drinking water utilities nationwide.

Additional Pilot Projects
EPA awarded funding for CWS pilots in New York City, San
Francisco, Philadelphia, and Dallas. These four additional
pilots were selected through a national competition and will
conclude in 2012.

 Phase III: Provide Guidance and Outreach

 Interim Guidance on Planning for Contamination Warning
 System Deployment (EPA-817-R07-005)
 Developing a CWS is a significant undertaking that impacts
 most departments and divisions of a utility at some phase of
 deployment.
  Deployment phases of a CWS include:
  • Planning and pre-design;
  • Design;
  • Implementation;
  • Preliminary testing;
  • Operation and maintenance; and
  • Evaluation and Refinement.
During planning and pre-design, the utility should
define design objectives for their CWS and conduct an
assessment and gap analysis to identify capabilities for
each monitoring and surveillance component as well as
consequence management. Utilities should also identify
and engage local partners that may have a significant role
in routine operations, such as local health departments
and environmental laboratories. During implementation,
enhancements are installed, operational procedures and
response plans are reviewed, revised, and reconciled, and
training for routine operation,  maintenance, and consequence
management should be conducted.

Baseline data will be collected during the preliminary testing
phase of the project. Once a sufficient level of baseline
testing has been completed, the utility will transition into full
deployment, and the CWS will be fully operational.

Interim Guidance on Developing an Operational Strategy
for Contamination  Warning Systems (EPA-817-R-08-002)
A preliminary operational strategy developed during
the design phase of the CWS can identify key users and
their requirements for information access, procedures to
guide system operation, information systems that may be
leveraged, and requirements for notifications to key users
and decision-makers.

The operational strategy should be developed with full
participation of the project management team and front-line
staff, including representatives from outside organizations
involved in the design or operation of the system. This
approach will build acceptance of responsibilities for system
operation, as well as ensure that system operations are
portrayed accurately.
   Steps to develop a preliminary operational strategy:
   • System-wide assessment of resources;
   • Component-specific analysis to develop standard
    operating procedures; and
   • System-wide integration of component-
    specific standard operating procedures into a
    comprehensive operational strategy for the CWS.
Interim Guidance on Developing Consequence
Management Plans for Drinking Water Utilities
(EPA-817-R-08-001)
A Consequence Management Plan serves as a guide for the
utility that describes the actions that should be taken upon
discovery of a possible contamination threat, as detected by
one of the CWS monitoring and surveillance components.
In the event of a confirmed contamination incident, the plan
provides information on remediation and recovery steps to
return the utility to normal operation.

This guidance document assists drinking water utilities
with planning, designing, implementing, and maintaining
an effective Consequence Management Plan as part of a
CWS. It also provides a framework for the integration of the
Consequence Management Plan with existing plans (such
as an Emergency Response Plan), training scenarios, and
outreach efforts to local, state, regional, and federal response
partner agencies.
