WESTON KS2 - Environmental Data Management

Environmental Data Management

Data Management Services (DMS) have built and operated numerous database software solutions specifically tailored to environmental remedial investigations and feasibility studies since 1986. EDM projects have ranged in size from 2,000 to over 750,000 chemical analytical points on numerous RI/FS projects, many exploiting WESTON's extensive GIS capabilities. These projects used:

An accounting-based approach to data management that insures legally defensible datasets with 100% data integrity.
Audit trails allowing data points to be traced from GIS to source documents in under 4 minutes.
Application of checks and balances from Chain-of-Custody to GIS and tabular analysis.
Industry standard Chemical Abstracts System (CAS) numbers used as basis for all compound identification.
Designed to be used independent of laboratory digital deliverables of highly variable quality.
Highly modular design allows for great flexibility.
Fully automated digital loading modules exist. These modules perform analytical group recognition to eliminate loading of missing or extraneous data points.
Double-blind hand entry module provides a cost-effective means of gathering the industries highest quality level for historical projects.
Validation procedure independent. Data modifications based on validation generate comprehensive audit trail.
Database is fully relational. Entity relationship diagrams (ERD's) exist for all data structures. Data structures are normalized.
Compound Rules of Precedence (CROP) module converts final analytical data set to be usable by GIS and statistical applications by applying rules of precedence to eliminate co-located data points.
Integrated Statistical Query System (SQS) allows users to interactively define, save and execute batch queries on the dataset for report-quality statistical and data listing tables.
GIS export module (GISX) prepares and delivers data to GIS for direct use.
