Drinking Water Program Bulk Uploads: Frequently Asked Questions

Frequently asked questions about eDEP filing of Drinking Water Bulk Uploads

When are the Drinking Water Bulk Uploads due to be submitted to DEP?

The timeframe for submitting Drinking Water Bulk Uploads through eDEP is the same timeframe as for submitting hardcopies to the DEP and is specified in the Massachusetts Drinking Water Regulations.

Can anyone submit Drinking Water Bulk Uploads to eDEP?

No, only registered eDEP users with a Laboratory Director or Laboratory Signer Proof of Identity can sign and submit Drinking Water Bulk Uploads to eDEP.

Should I still submit hard copy forms to the appropriate DEP regional office?

There is no need to mail anything, your eDEP submittal serves as your submittal to DEP. You do not need to send hard copies of the forms.

How do I know if the Drinking Water Bulk Uploads have been accepted through eDEP?

The Lab will get a receipt with a DEP Transaction ID indicating your transaction has been completed. Lab clients can request to be cc’d on the receipt.

After your report is uploaded into eDEP it will be reviewed for reporting errors by Rules Based Processing software and DEP staff. If the submission gets rejected and email will be sent to the lab indicating the error(s) identified. The Public Water Supplier is responsible for obtaining the correction from the appropriate party (in this case the laboratory) and is also responsible for seeing that the corrections are submitted to the DEP within 30 days.

Will the format of Drinking Water Reports change with Drinking Water Bulk Uploads?

The implementation of eDEP has necessitated a change to the format of some Drinking Water Program reports. Reports normally completed by a Massachusetts Certified Laboratory can submit their data sets through eDEP via Drinking Water Bulk Upload, or they can submit their data by hardcopy on one of the new forms. New forms were mailed to all Public Water Suppliers and Certified Laboratories and are posted on the DEP website.

Note: eDEP is required for PFAS and many other contaminant groups

How do I submit the DBPR Compliance section if my lab is uploading data through eDEP?

There is a form available for Public Water Suppliers to submit the compliance information required under the DBPR rule. This form must be mailed to DEP.

Can I edit and/or add data to a Drinking Water Bulk Upload after it has been submitted?

Once an upload has been submitted, it is no longer available for data entry or changes, only viewing and printing. If corrections are needed, contact Andrew Durham or Sage Grace using the contact information below.
