Data Tools

The Data Tools area provides contractors and laboratories with the ability to transmit environmental analytical data to Tetra Tech in an electronic format. The applications will review data files for adherence to the Tetra Tech data structure and content requirements, such as column completeness and compliance to the data types and lengths specified in your laboratory Scope Of Work (SOW). Use your SOW and the descriptions below to navigate to the appropriate data checker application and submit an Electronic Data Deliverable (EDD) for a project.

The Laboratory EDD Checker (LEDD Checker) is for fixed-base laboratories submitting analytical EDDs in the A1, A2 and A3 TEXT file format. Click the LEDD Checker menu item to access the application.

The Streamlined Laboratory EDD Checker (S-LEDD Checker) is for laboratories submitting analytical EDDs in a streamlined (flat EXCEL file) format. Click the S-LEDD Checker menu item to access the application.

The Mobile Laboratory EDD Checker (M-LEDD Checker) is for mobile laboratories submitting analytical EDDs in an EXCEL file format. Click the M-LEDD Checker menu item to access the application.

All EDDs must be submitted to Tetra Tech through the the appropriate Checker application.
