EQuIS Data Submittal

The Department of Natural Resources and Environmental Control (DNREC) maintains an EQuIS™ database, from EarthSoft® Inc., to store and analyze both field and laboratory data about facilities and sites that are the subject of regulatory, remediation or other management efforts of the Department.

The following information provides instructions for reporting data electronically to the Department using Electronic Data Deliverables (EDDs) through the EQuIS system.

Important: Contact the DNREC Project Officer assigned to the facility/site first (and prior to sampling) to determine what data should be submitted.

Step 1: Submit Basic Facility (aka Site) Information

Prior to submitting EDDs, the DNREC Project Officer or the data provider must submit the basic facility/site information, listed below, in an email to

  • Facility/Site Name
  • Facility/Site ID (If applicable – e.g. DE-1005)
  • Project Officer Name
  • Data Provider Name (company name and primary contact person for EDDs)
  • Facility/Site Address (street, city, zip code, county)
  • Program the Facility/Site is Part of: Brownfields, DOD/FUDS, HSCA, LAST, LUST, NPL, PA/SI, RCRA CA, Resource Recovery, Solid Waste, SSA, or VCP

The Database Manager will create the new facility/site in the database and then the data provider can begin to submit EDDs. You will receive confirmation when this is complete. If the facility/site already exists in the database and the basic facility/site information has not changed, then the DNREC Project Officer or data provider does not need to provide this information again.

EQuIS Documents and Reference Files

This collection includes the documents, program files, and reference files for the EQuIS system. Documents and files highlighted in italics on this page are found at this link.

Step 2: Prepare the EDD

Electronic data must be submitted in DNREC’s custom EDD format. Data providers should download and add facilitysSite data to the Blank EDD . The EDD description provides information about the fields within each section of the Blank EDD.

Data providers must populate all required fields in the EDD, however not all sections of the EDD must be populated. Specific fields have controlled vocabulary as well and must be populated in compliance with DNREC reference values and enumeration values.

Please review DNREC’s Electronic Data Deliverable Submittal Requirements Manual for EQuIS for more detailed instructions and examples.

Step 3: Check the EDD

DNREC data providers should download and use the newest version of the EQuIS Data Processor (EDP). The EDP is a tool used to check data files against DNREC’s EDD requirements. All EDDs must be checked for errors by data providers by loading data into the EDP and must be error-free before they are submitted to DNREC.

Please see the DNREC EDP User Guide for directions for how to use the EDP and how to load the DNREC Format File and Reference Value File.

Note: Using the DNREC Format File requires registration. When you first open the format file in the EDP, you will be required to register the format file. Select the link to Register. Then select the link to request a registration key for your computer and submit the required information. EarthSoft will provide you with a registration key once your information has been approved.

Adding New Reference Values

Please follow DNREC reference values as closely as possible when populating EDDs. However, if you need to add a new reference value to the database to submit your data, please send an email to including:

  • Your name and your company name
  • Reference value you want to add
  • Name of reference table the value belongs in (i.e. rt_analyte)
  • Brief description of the reference value
  • Reasoning as to why the value is needed

Step 4: Submit the EDD

Consultants should submit both lab and field EDDs as a zipped file via email to with a carbon copy to the DNREC Project Officer.

Labs contracted by a consultant should submit lab EDDs to the consultant and not to DNREC directly.

Labs contracted by DNREC should submit lab EDDs via email to

Please see DNREC’s EDD Submittal Requirements Manual for EQuIS for more instructions regarding data submittal.
