EXES Data Management
Process
Challenges
• Changing site requirements for analytical
services
• Standardization vs. specialization, data
collection, and data management
• New and legacy systems and databases
• Additional security requirements
• Budgetary constraints
• Communication
• Adapting to changes/needs of our customers

Examples of Variances
• Analysis
–Varying analyte detection requirements for projects
– Matrix issues
• Data Delivery
– Lateness
– Incomplete/non-compliant data
• Data Assessment
– Quality affected by laboratory errors, field errors, etc.
– Combination of special requirements (i.e., multiple formats)

Why Optimized
Data Assessment?
• Provides data users with confirmed results and
confidence in usability of data
• Standardized protocols incorporate quality control
procedures and criteria
• User can define any level of data validation or
assessment
• Documented savings of 80% over manual data
validation
• Efficient, consistent and timely

What is EXES?
• The Web-based data assessment/validation and
management tool that can evaluate analytical data
based on method requirements, and provide users
with advanced customization capabilities to review,
edit, and add evaluation parameters, tests, Method
Quality Objectives (MQOs), and Quality Assurance
Project Plan (QAPP) requirements. It uses:
– Format neutral domain and data model,
– Re-usable Process Flow Libraries (PFL),
– Method Evaluation Libraries (MELs); and
– Method Evaluation Procedures (MEPs).

EDM Advantages Over Traditional
Records Management
• Files available to all those given access on a
Universal, Regional Contractor, site, or project
level.
• Records will be retained and sent to
Superfund Enterprise Management System
(SEMS) for archiving.
• Easy access to data for later review or
litigation.
