Since the inception of the EPAs Central Data Exchange (CDX), Erthwrks has been preparing and submitting reports for our clients throughout the United States. In Fall 2016, Erthwrks worked directly with the EPA to expand and edit the offerings to correctly record and report quality assurance methods for BGLT testing within refineries, including implementing EPA Method 25B and EPA Method 25A. Erthwrks both submits our own reports for a nominal fee, as well as provide consulting and review services for other CEDRI reports generated via the Electronic Reporting Tool (ERT).
