The Archive of Massachusetts Environmental Data
In August of 2017, the MA Executive Office of Energy and Environmental Affairs (EEA) began operating an “Enterprise Data Portal” for certain state regulatory data. Initially, this has included permit, facilities, inspections, and enforcement, and drinking water testing data; more data assets are promised “regularly.”
Data on combined sewer overflows (CSOs) were added in 2022 and now incorporated in AMEND. Other data tables added to the portal in recent years are not yet integrated.
Definitions, FAQs, disclaimers, and other information related to these datasets is available in PDF format at the EEA Data Portal website’s help page and archived here:
One of these datasets, the historical drinking water quality measurement dataset, is significantly larger than the other (>200 MB in total). Because this measurement-level drinking water quality reporting is not instrumental to the goals of AMEND, we do not include it in our integrated database. We do provide an archived version of the complete drinking water dataset below.
The data from this portal has been archived on this site, last updated on 27 October 2026 11:50 am. The CSO data is queried using a separate script and was last updated on 27 October 2026 11:51 am. Both datasets are refreshed automatically on a weekly basis.
In addition to including them in them in the integrated AMEND Database, we provide our archives of each of these data assets in CSV format:
For brevity, a random sample of 10 rows from each table and a subset of all columns is shown below for illustration as to the tables’ form and content.
