This data layer provides access to Brownfields Properties as part of the CIMC web service, although the data are generally more broadly applicable. Brownfields are real properties, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these properties takes development pressures off of undeveloped, open land, and both improves and protects the environment. CIMC provides information on Brownfields properties for which information is reported back to EPA, as well as areas served by Brownfields grants programs. Brownfields properties may be mapped or listed, and property profiles can be accessed from either maps or lists. There are many properties that meet the definition of a brownfield but are not funded by our program. They may be funded by states, localities, private or non-profit entities. The Brownfields data are reported by grant recipients via the ACRES database and updated and stored in Envirofacts monthly. For more information on the data updates to Envirofacts, please visit the Envirofacts Data Update page. For more information on the data provided through this webservice, please see the processing steps below, and see more information here: https://www.epa.gov/cleanups/cimc-about-data#brownfieldsp. The CIMC web service was initially published in 2013, but the data are updated twice a month.
