Database Request

The Division of Environmental Response and Revitalization (DERR) have several databases which are available to the public upon request. The DERR database is an index of sites throughout Ohio for which our district offices maintain files. There are also several archived databases, which are no longer maintained, of older sites. Please click a link below for more information.

The Division of Environmental Response and Revitalization (DERR) database is an index of sites for which our district offices maintain files. The database is NOT a record of contaminated sites in Ohio. Not all sites in the database are contaminated, and a site's absence from the database does not imply that it is uncontaminated. The database is also not a list of brownfield sites. Not all sites in the database meet the federal or state definitions of brownfields, and many properties in Ohio which would qualify as brownfields are not in the database.

The DERR database contains basic site information only. Site information maintained in the database includes the name and address of the site; its latitude and longitude; whether the property is, to Ohio EPA's knowledge, being cleaned up in accordance with the Voluntary Action Program (VAP) or is receiving technical assistance through the VAP; and whether Clean Ohio Fund money has been issued to remediate the site. Detailed information regarding the status of each site can be provided by the appropriate District Office.

Master Sites List Information

The Master Sites List (MSL) was created in 1988 for the listing, tracking and reporting of potentially contaminated sites in Ohio managed by DERR. It listed sites where there was evidence of, or it was suspected that there was, contamination of air, water or soil, and there was a confirmed or potential threat to human health or to the environment.

The MSL no longer exists; it was last updated in 1997 and last published in 1999. When it was in existence, the MSL was a query of the larger DERR database. For questions about or to request information from the DERR database, please click here.

Archived Databases

The following are descriptions of several archived databases that are available from DERR upon request. Please keep in mind that these databases are no longer maintained and may contain inaccurate or outdated information. Therefore, Ohio EPA disclaims any responsibility for wrong or misleading entries.


A list of about 1200 old abandoned dumps or landfills. This database was developed from Ohio EPA staff notebooks and other information dating from the mid-1970's, including old Division of Solid and Hazardous Waste Management and DERR fiiles, the Eckhardt Report and the 1976 Groundwater Pollution Inventory-Summary of Land Disposal.


This database of about 2800 sites respresents Àœpits, ponds and lagoons? where various types of sludge were dumped over many years. The object of this data collection was to determine if harm was done to drinking water supplies below each dump site. The data were collected during the 1970s and published by U.S. EPA in 1980.


A list of 82 sites of coal gas generators in Ohio. These plants produced gas for street lights in the communities in which they were located. The production of one million cubic feet of gas also produced about 800 gallons of liquid coal tar, which is a carcinogen. TOWNGAS was developed from a database from Radian Corporation along with information from the Ohio Historical Society and various public libraries.
