Data Management Issues
• Multiple databases, processes, procedures,
and methods for the same information
• Consistent and stable business driven
framework needs to be prescribed with all
data generated registered into an Agency
catalogue

2
Data Management Goals
• Need to develop and implement:
– paperless data generation
– paperless data transfer/exchange
– review and management (input and retrieval)
systems for all types of project data (e.g., field,
chain-of-custody, analytical)

Some Data Management
System Concepts
• Need to build systems that are used regularly
• Same systems for regular and emergency
use
• System should be capable of being scaled up
or down (e.g., number of samples, reporting
of QC data)
08/16/2011

Data Management Frameworks:
Examples
• EPA’s Environmental Response Laboratory
Network and Water Laboratory Alliance
• EPA’s Contract Laboratory Program
• USACE ADR.net

General Environmental Data Flow:
Needs for Going Electronic
• Standard formats for electronic project
requirements.
• Standards/templates for field information.
• Standard formats for reporting analytical data.
• Standard procedures for reviewing analytical
data.
• Standard formats for reporting reviewed
analytical data
08/16/2011
7
Standard Format Requirements
• Non-Proprietary Formats (e.g., XML)
• Use international standards for Valid Values
(e.g., ISO, IEEE, ASTM)
• Guidance/Specification/Requirement
Documents
08/16/2011
8
First Needs:
Data Capture Requirements
• Need to develop the following:
– Standard Specification for Laboratory Instrument
Output files (e.g., NIST’s AnIML)
– Standard Specifications for Laboratory Information
Management Systems (e.g., as an RFP)
– Standard Electronic Versions for Measurement
Quality Objectives (e.g., ERLN WebEDR MQO
Template)
08/16/2011

Followed By:
Adoption of Standard Reporting
Formats/Guidance
• Laboratory Data
– e.g., Staged Electronic Data Deliverable (SEDD)
for EPA (ERLN, CLP, GLPNO) and USACE
programs, ERLN EDDs
• Chain-of-Custody Information
– e.g., WLA Response Plan (Appendix H)
08/16/2011
10
Then:
Data Reporting Formats/Tools
• EPA and NIST
– Developing an electronic deliverable that contains
all laboratory and instrument data in a nonproprietary format for archival and retrieval (SEDD
with AnIML)
• EPA Forms Generator
– Generating different reporting formats from the
same electronic deliverable (e.g., CLP and CLP –
like forms)
08/16/2011
11
Leads to:
Data Assessment
• Data Analysis or Assessment
– Confidence in the reliability of data and ability to
use appropriately are important
– Consistent application of the data life-cycle and
enforcement of data quality policies for greater
confidence
– Scientific Integrity

Facilitating Data Assessment by
Automating Data Review
• Example Data Review Software
EPA ERLN WebEDR, EPA CLP EXES,
USACE Automated Data Review.NET
• Need Specifications for Data Review
Software
08/16/2011
13
Facilitating Data Assessment by
Identifying Data Quality
• Capturing Data Review Steps In End User
Databases
– e.g., EPA’s Guidance for Labeling Validated
Analytical Data
08/16/2011
14
Why do all this:
Benefits
• Ease of data exchange
• Ease of data storage and retrieval
• Allows for verifying reported data (current and
in future)
• Allows for reuse of data
08/16/2011
15
Getting to an Electronic World
• Need to get rid of the “Not-Invented-HereSyndrome” (i.e., adoption of agency specific
standards/systems)
• Need all parties (Federal and State Labs) to
cooperate and adopt a set of data
management standards that can be used by
all parties
