Environmental data management

Environmental data you can defend.

Import laboratory and field data without losing the original record. CHEMDAS validates each file, standardizes values, and shows exactly what changed.

How CHEMDAS works

From source file to usable data.

Keep the reported values. Add standardized values. Record each validation and change.

  1. 01

    Preserve

    Store the source faithfully.

  2. 02

    Derive

    Calculate standardized values alongside it.

  3. 03

    Verify

    Retain rules, actions, and integrity evidence.

  4. 04

    Activate

    Screen, trend, query, export, and integrate.

Import Audit Report

Illustrative sample data

The top of a CHEMDAS Import Audit Report for the sample organization Illustrative Data Co. (sample), Demo Project A. Under the heading Data Integrity Verification, two boxes: Audit Sequence Continuity reads VERIFIED, over 20,981 total audit entries with 20,981 entries verified, noting that each entry's hash links to the previous one in sequence to confirm no audit entry was inserted, deleted, or reordered; Committed Record Integrity reads VALID, with the note that every committed record's content hash recomputes to the value captured at commit, so no committed row was altered afterwards.
Captured from the shipped report over 100% synthetic data · every count, rule and hash was produced by the real import pipeline · the organization name in the header is the disclaimer

Made for environmental work

Field records become decisions. Keep the path between them clear.

CHEMDAS connects laboratory deliverables with the work of data managers, project leads, and reviewers.
