SDWIS State Background
 EPA-developed system used by Primacy Agencies to
manage their PWSS programs
 Used to determine water system compliance with the
National Primary Drinking Water rules
 Includes many other features for managing…
• Engineering information/inspection results
• Drinking water buyer/seller/ownership
• Administrator/Operator/Emergency contacts
• Assistance and enforcement actions
• Laboratories and samples/sample results
• Monitoring and sampling schedules

SDWIS Data Flows – State to EPA using
Current SDWA 3.0 XML Schema
CDX
 All states use FedRep to validate SDWA XML document
• FedRep also extracts data from SDWIS State
 States can submit other samples, but it’s voluntary and not
loaded into the SDWIS Fed Data Warehouse

Reports
 ODS Transformation Services checks the submissions and adds
referential integrity to the resulting database objects
 SDWIS Fed Data Warehouse (SFDW) creates new objects
based on reported and derived data optimized for querying
 SFDW extracts go to OECA’s ECHO system, EnviroFacts, and
various reports

 Lab-to-State is a CROMERR-compliant portal where labs
can submit sample data as eDWR XML or.csv files.
 Lab-to-State produces an XML file with lab results
document
 SDWIS XML Sampling is used to parse the eDWR
document and load samples data into the SDWIS State DB

Determining Compliance
 SDWIS compares the schedules (when to take certain
samples) with the sample results
 If no samples are loaded within the date range, then
SDWIS will generate a candidate M&R violation
 If samples exceed certain values, then SDWIS will
generate the appropriate MCL, MRDL, TT, or Other
candidate violation
 Primacy Agencies accept or reject candidate violations
 Accepted violations are sent into EPA using the
process described earlier

The National Perspective – Data
Transformations
 State reported data are stored as-is in SFDW
 Derivations are used to improve query performance
and make assumptions about data
• Inactive water system – active facility
• Ground water or surface water sourced system
• Correcting coordinates for water system facilities located
in Manchuria
 “Total replace” of data each quarter
 Previously reported data not reported in current quarter

The National Perspective – an
Incomplete Picture
 Current data flows to EPA are exception-based and
focused on compliance
 Insufficient data for
• Measuring effectiveness of current regulations and
treatment technologies
• Giving the public a consistent view of the quality of their
drinking water
 Leaves the drinking water regulatory community with
letting others tell the drinking water story at the national
level

Administrator’s Drinking Water Strategy
Goals – March 2010
1. Address contaminants as groups rather than one at a
time so that enhancement of drinking water protection
can be achieved cost-effectively
2. Foster development of new drinking water
technologies to address health risks posed by a broad
array of contaminants
3. Use the authority of multiple statutes to help protect
drinking water
4. Partner with states to develop shared access to all
public water systems (PWS) monitoring data
5/30/12
Office of Water | Office of Ground Water and Drinking Water | USEPA
13
Data Sharing Goals
1. Promote the use of advanced technologies for facilitating
information and data exchange between states and EPA
2. Enhance compilation and analyses of PWS information to
strengthen the analysis of potential drinking water public
health concerns without additional on the states
3. Share powerful data analysis tools with states to target
program oversight, compliance assistance, and
enforcement to needed areas based upon risk to public
health
4. Implement interactive communication tools enabling states,
the utilities, and consumers to obtain timely information for
learning more about their drinking water and performance
of drinking water systems for public health protection

EPA/ECOS/ASTHO/ASDWA Data
Sharing MOU
 Negotiated and signed Nov 2010
 Data Sharing Implementation Work Group (IWG)
launched Dec 2010
• Primary goal: Recommend to the MOU Steering
Committee a set of compliance monitoring data (CMD)
elements which would eventually would be housed in
SDWIS NextGen and shared with EPA
 Using SDWIS State as a basis, the IWG identified the
set of CMD data elements
 Sep 2011, IWG issued its report to the MOU Steering
Committee recommending the CMD elements

ECOS IPT – Implementing the CMD Data
Flow
 IPT launched in Jan 2012
• Laurie Cullerot, NH and Greg Fabian – co-chairs
• Work on defining the XML schema began in advance
 Scope is to go beyond the EPA-Primacy Agency
exchange by considering other stakeholders
 Identified additional data elements requested by
• CDC – Public Health Tracking Network
• APHL – Lab QA data
• Six year review data submission (“ICR”)
 Developed SDWA 4.0 schema

Mapping Tool
 Data mapping tool – maps Primacy Agency data sources to the
SDWA 4.0 schema and validates/checks errors
 Intention is for EPA to provide mapping tool to the Primacy
Agencies

Data Mapping Pilot
 Started late April, scheduled completion June 11
• AR, LA, NH, NY and OR
• OH used by contractor as a basis for mapping
 Goal is to
• Test the SDWA 4.0 schema
• Evaluate efficacy of using off the shelf data mapping tools
• Altova Map Force selected for the pilot
• Transmit data using SDWA 4.0 through to CDX
 If the mapping tools prove useful, EPA will
• Develop scripts for mapping SDWIS State data
• Provide mapping tools to the primacy agencies
• Offer some training in tool use

Additional Flows to Test
 Focus right now is on CMD flow from Primacy Agencies
to EPA
 Other flows need to be tested, such as:
• Labs to Primacy Agencies
• Tribes and Territories to EPA Regions
• Primacy Agencies to CDC
• Flows between agencies within a state and regions
• Flows between Utilities and Primacy Agencies

Beyond SDWIS to NextGen –
Architectural Highlights
 Cloud-based hosting
• One app, one database with secure areas within the
database for each Primacy Agency
 “Componentized” application using Service Oriented
Architecture (SOA)
 Leverages Business Process Management (BPM) for
workflow management and compliance determination
• Supports process improvements geared to reducing the
amount of time users spend in the system
 Delivered to the end user through their web browser

Regulatory Users
 Primacy agency users are the end users and will use
NextGen as part of their day-to-day activities
 Primacy agency systems interface with NextGen and
provide additional features specific to each agency
 EPA Regional users have oversight responsibilities for
their states and may have different access needs than
EPA HQ users
 EPA HQ users have program oversight responsibilities
at the national level
• Includes OGWDW and OECA uses of data reported to
EPA
5/30/12
Office of Water | Office of Ground Water and Drinking Water | USEPA
23
Non-Regulatory Users
 Other federal agencies, such as CDC and DHS, are
consumers of SDWIS data (occurrence, locations, etc.)
 The public can view data pertinent to the quality of their
drinking water or for other studies and purposes
 Laboratories may submit sampling data and results to
SDWIS NextGen*, which may route the data to the
cognizant state
 Utilities may…*
• Approve samples submitted to SDWIS NextGen
• View/request modification of certain data elements
• There are probably other use cases yet to be defined
*Requires further analysis

NextGen Value Proposition
 Primacy Agencies…
• Will spend less time “feeding the system” because of
process improvements built into NextGen
• Beginning effort to identify business process improvements
• Do not have to maintain their own IT infrastructure and
the staff needed to support NextGen
• Reduced cost for upgrading/easier access to upgrades
 EPA…
• Reduced software maintenance cost – one app, one
version
• Reduced operating cost – cloud hosting

Some NextGen “Gotchas”
 ODBC connectivity to the NextGen database
• Many Primacy Agencies have “add-on” applications that
connect to SDWIS State using ODBC
• Web services can be used instead in many cases
 Perceived loss of control of data
• Data are no longer physically located in a state data
center
• Ensure Primacy Agencies can control access to their data
 Cost model still being worked out
• Primacy Agency cost sharing with EPA using grants?

What’s Next?
 Complete the data mapping pilot and other flows
 Distribute data mapping tools to Primacy Agencies
• Begin flowing CMD and 6-year data
 Complete NextGen Business Process and
Requirements Analysis by Oct 2012
 Establishing parts of the solution architecture –
BPM/BRE and SOA/ESB
 Full Next operational capability in Sep 2014
 Decommission SDWIS State Sep 2015
