CIMC - About the Data


Accidents, spills, leaks, and past improper disposal and handling of hazardous materials and wastes have resulted in tens of thousands of sites across our country that have contaminated our land, water (groundwater and surface water), and air (indoor and outdoor). EPA and its state, territory and tribal partners have developed a variety of cleanup programs to assess and, where necessary, clean up these contaminated sites.

Cleanups in My Community is intended to provide information about sites that might need to be cleaned up, are being cleaned up, or have been cleaned up, in your community or anywhere in the United States. The information can help people understand what is happening in their community, what has happened, and, with the contextual information provided, what could happen if certain events take place.  We provide what data are available, and those data are limited by what we can legally generate and collect. See legal notices page for more information on data limitations.

CIMC is an ever-green application – always improving. We are open to new ideas on how CIMC can be improved, please contact us with your ideas.

Current Scope of Sites Included in Cleanups in My Community

Currently, CIMC only shows sites, facilities and properties for which EPA collects information by law, or voluntarily via grants. At present, this does not include state or locally funded cleanups. In addition, data in this system is updated according to certain update or refresh schedules which vary by application and may not yet reflect real changes at the locations covered here.

Currently, CIMC only includes data for the following EPA cleanup programs:

  • Brownfields Properties: Grantees may report information on Brownfield properties receiving federal grants. Data, which dates back as far as 1998, are collected from grantees via ACRES. These data are pulled into CIMC twice a month.
  • Brownfields Grants Jurisdictions: Geographic areas covered by specific Brownfields grants. These data are collected through ACRES. These data are pulled into CIMC twice a month.
  • RCRA Corrective Action: Facilities cleaned up under the corrective action program of the Resource Conservation and Recovery Act (RCRA). These data, dating back to 1980, are collected from the states using RCRAInfo. Only facilities data which states designate as being on the 2020 Baseline for Corrective Action and for public access are included in CIMC. These data are pulled from the RCRAInfo webservice twice a month.
  • Superfund and RCRA Corrective Action Boundaries: We are working with EPA regions to provide Superfund site boundaries, RCRA Corrective Action boundaries and control area boundaries (operable units, institutional control areas, LUCs, AULs, etc.) through CIMC.  These are not official boundaries and have no legal standing, but are provided as a public service.  For more information, please see our Legal Notices. At present, boundaries for EPA Regions 1 and 3 are available in CIMC. Additional boundaries will be added as they become available to the CIMC team.
  • Superfund: Superfund sites that are on the National Priority List (NPL), are proposed for the NPL and have been deleted from the NPL are in CIMC going back to 1982.  Data are collected from EPA Regions via the Superfund Public Use Database (SPUD) and are pulled into CIMC twice a month.
  • Federal Facilities and Federal Agency Hazardous Waste Compliance Docket: Sites that are owned by federal government agencies and have hazardous waste cleanups are included in CIMC.  Data are collected using the Superfund Enterprise Management System (SEMS) public database, the Federal Registry System (FRS) and RCRAInfo and are pulled into CIMC twice a month.
  • Removals/Responses: Generally, more urgent cleanups. Data are provided by On Scene Coordinators (OSCs) through and pulled into CIMC twice a month for additional access to the public.  However, data about Incidents of National Significance (INS) are located on their own EPA web pages, and CIMC links to those pages.
  • Recovery Act Funded Cleanups: CIMC provides information on Superfund and Brownfields site cleanups that received ARRA Recovery Act funding, but not on the Leaking Underground Storage Tanks sites. For information on all EPA Recovery Act funded work, please see: EPA’s Recovery Mapper.

Additional Information about Cleanups

  • Alternative Energy Potential at Cleanup Sites: EPA's Office of Communication, Partnership and Analysis (OCPA) within the Office of Land and Emergency Management (OLEM) has developed information about the alternative energy potential of each cleanup site, including some additional cleanups "landfills".  Links labeled "Estimated Renewable Energy Potential" in each site's pop-up box provide calculated data about the potential of the site for wind, solar, biomass and geothermal energy generation.  For more information on the sites covered, and the calculation of the potential, please see the RE-Powering Mapper.
  • Census Data: EPA's Environmental Justice program has developed EJScreen which includes Census Reports for areas defined by a point and radius around a site.  CIMC taps into these reports for Census 2010 data and US Census American Community Survey (ACS) data updates.  These Census reports are provided as links from the map pop-up boxes for each site.  When the Census 2020 data become publicly available, we will start using them.
  • Links are provided to some additional resources to help you access local, state and federal information about cleanup sites that are not reported back to EPA and/or are not in Cleanups in My Community. These links are available at the bottom of the Cleanups in My Community page.

Other (non-cleanup) Data Mappable in CIMC

The following data are provided in the CIMC mapping interface in order to provide context for additional analyses:

Cleanup Program and Status

Each cleanup program is founded on different legislation with different reporting and tracking requirements. Consequently, the categories used, and the information available for each program is different.


Brownfields data in CIMC includes both properties and grants jurisdictions:

Brownfields Properties

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 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.

Brownfields Grants Jurisdictions

Only properties benefitting from EPA Brownfields grant funding and technical assistance appear in Cleanups in My Community. There are different types of grants and each grant covers a specific area of geography. Grant areas can overlap, and often do. You can map and list Brownfields grant areas. Simply choose Brownfields Grants as your program filter and map or list them for the geography you choose. On the map, Brownfields jurisdictions will be shown as colored boundaries. Grant Jurisdictions have their own reports and fact sheet. You can get to the reports by choosing to map the grant areas and then clicking on the areas on the map, or by clicking on a report in the grant listing. For more information on Brownfields grants, see Brownfields Grants and Funding


The Brownfields data are reported by grant recipients via the ACRES database and updated in CIMC twice a month. Brownfields property information is obtained via the "Property Profile".  Please see "Instructions for Completing Brownfields Property Profile Form" for more detailed information about each field. Data in CIMC reflect data considered by ACRES to be “final” versus “draft” data that might still be pending approval.

The Brownfields grant jurisdictions are developed by EPA based on the grant title.  Generally, these grant jurisdictions are standard geographic political areas such as states, counties, and the Census equivalents of cities, towns, etc.  When the grant geography is non-standard, we work with the grant project officers at EPA to correctly draw the grant jurisdiction areas.

RCRA Corrective Action

The Resource Conservation and Recovery Act, among other things, helps ensure that wastes are managed in an environmentally sound manner so as to protect human health and the environment from the potential hazards of waste disposal.

In particular, (RCRA) tightly regulates all hazardous wasteHelphazardous wasteBy-products of society that can pose a substantial or potential hazard to human health or the environment when improperly managed. Possesses at least one of four characteristics (ignitability, corrosivity, reactivity, or toxicity), or appears on special EPA lists. from "cradle to grave." In general, all generators, transporters, treaters, storers, and disposers of hazardous waste are required to provide information about their activities to state environmental agencies. These agencies, in turn pass on the information to regional and national EPA offices. Accidents or other activities at facilities that treat, store or dispose of hazardous wastes have sometimes led to the release of hazardous waste or hazardous constituents into soil, ground water, surface water, or air. When that happens, the RCRA Corrective Action program is one program that may be used to accomplish the necessary cleanup.

In Cleanups in My Community, you can map or list RCRA Corrective Action sites that are currently undergoing corrective action, sites for which a remedy has been selected, sites for which construction has been completed, and sites where the corrective action cleanup is complete (More on RCRA Corrective Action).

Note: RCRA facilities which are not undergoing corrective action are not considered “Cleanups” in Cleanups in My Community. The complete set of RCRA facilities can be accessed via the RCRAInfo data in Envirofacts.

Data The RCRA Corrective Action data in CIMC comes from the RCRAInfo webservice that have been flagged by states as both open to public access and on the Corrective Action 2020 Baseline. If the state has not flagged the data as both open to public access and on the Corrective Action 2020 Baseline, it will not appear in CIMC.  Data are updated twice a month.  For more information, please see: 


Superfund is a program administered by the EPA to locate, investigate, and clean up the worst hazardous waste sites throughout the United States. EPA administers the Superfund program in cooperation with individual states and tribal governments and data included in CIMC dates back to 1982. These sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills - the key word here being abandoned.

Only those currently on the National Priority List (NPL) have been included in Cleanups in My Community thus far. In Cleanups in My Community we have used the term NPList because not everyone knows what NPL means and National Priority List is too long a title for the list in the list box. (More on Superfund)


EPA maintains a National Priority List (NPL), which identifies for the States and the public those sites or other releases that appear to warrant remedial (long term) actions. These NPL sites fall into the following categories:

  • Proposed: Through the Superfund NPL Site Listing Process, sites may be proposed for the NPL. 
  • Final: Those sites placed on the NPL are called "final," and for these sites, a cleanup remedy is selected and implemented. However, it may be several years after construction of the remedy is completed before the hazardous substances are completely cleaned up or controlled in place.
  • Deleted: After the cleanup process is complete, and appropriate reviews confirm the area is cleaned up or the hazards are controlled, sites can be deleted from the NPL.


Superfund NPL data come to CIMC through two mechanisms.

  1. Information shown on the CIMC maps (including the latitudes and longitudes) and listed in the lists of sites, originates with the Superfund Enterprise Management System (SEMS), but goes through additional Quality Control in EPA's Facility Registry System to:
    1. Ensure the latitudes and longitudes are within the proper ranges based on the county, state and other geographic identifiers provided for the site, and that the coordinates we use are supported by the best metadata we have available, and
    2. Match up the data from SEMS with data about the same sites from other EPA programs. We are continually in the process of improving this information, such as latitude and longitude information, which may not have method, accuracy and description information.

For more information on the Superfund data in FRS and Envirofacts, please see the Envirofacts SEMS overview page. For more information about the quality of the data in FRS, see the FRS home page, the FRS documentation and the FRS Programs Crosswalk. And for more information on data updates to RFS, please visit the FRS Data Source Refreshes page.

  1. CIMC then links to the Superfund Site Home Pages created by combining data from SEMS with site-specific data from the regions. These data describe what has happened at Superfund sites as well as what is planned. For more information about the quality of the data in SEMS, see Superfund Data and Reports.  For additional site-specific Superfund searching, please see Search Superfund Sites Where You Live and Search Superfund Documents.

*Data in CIMC are updated twice a month. 

Federal Facilities

Federal Facilities are properties owned by the federal government. Federal Facility sites can be either Superfund sites or RCRA Corrective Action sites, or they may have moved from one program to the other and back. In Cleanups in My Community, you can map or list any of these Federal Facility sites. Base Realignment and Closure (BRAC) sites are also included in CIMC. (More on Federal Facilities)  The Federal Facilities Docket is a subset of the Federal Facilities in CIMC.


Removals are hazardous substance releases that require immediate or short-term response actions. These are generally addressed under the Emergency Response program and are tracked centrally by the federal government's National Response CenterExit. Cleanups in My Community maps and lists removals that are included in EPA’s Response site listing, and provides direct links to information on these sites. CIMC obtains updated removal data (going back to 2001) through a web service from the EPA OSC Response WebSite twice a month. 

American Recovery and Reinvestment Act

The American Recovery and Reinvestment Act was signed into law by President Obama on February 17th, 2009. Out of the five EPA programs that distributed recovery act funding, three of them were cleanup programs: Brownfields, Superfund and Leaking Underground Storage Tanks. CIMC provides information on Superfund and Brownfields site cleanups that received ARRA Recovery Act funding, but not on the Leaking Underground Storage Tanks sites that received ARRA Recovery Act funding. Data for Brownfields comes from the ACRES database. Data for Superfund comes from the CERCLIS database within SEMS. Recovery Act data are no longer updated since the program ended. For information on all EPA Recovery Act funded work, please see: and


You can search for sites in Cleanups in My Community based on the following types of geography:

  • Street Address – You can put in the street address, city, state, ZIP code (e.g. 123 Main Street, Arlington, VA) for any address in the US, and request a certain radius around it to define your geography of interest. Addresses are “geocoded” on the fly to find the best possible latitude and longitude on the map. CIMC uses geocoding services available through its Facility Registry System to locate the latitude and longitude of that address and then maps the area with the sites, or lists the sites in that area.
  • County, City or ZIP – Choose what type of geography you want to use, and then enter the name of the county or city or the ZIP code of interest. Be sure to specify the state in which the county, City or ZIP exists.
  • National – You can retrieve the whole country (including Alaska and Hawaii, etc.) or just the 48 contiguous states. Mapping or getting a listing for the whole country can be slow, so you may want to limit the types of sites in your search based on the categories above. If the site locations do not appear after the rest of the map has appeared, try refreshing the page.
  • Cleanup Name – You can enter the name of a specific cleanup (e.g., Port Washington) and the CIMC map will zoom in as much as possible to that location. In fact, to see the surrounding area of the cleanup, you will need to zoom out several levels. If you see a large section of the US when using the Cleanup Name option, it may be that there is more than one cleanup with that name. The Cleanup Name function will show the chosen cleanup(s) with a different site icon, so that it is distinguishable from the others.
  • Cleanup ID - Similar to Cleanup Name, although Cleanup IDs are specific to each program. 
  • FRS Registry ID – You will probably only use this if you are familiar with EPA’s Facility Registry System (FRS), but you can obtain the FRS "Registry ID" by finding the cleanup using the FRS EZ query. Please see Cleanup Name above for information about zooming.
  • State or Territory – Choose a state or territory from the list of states and territories.
  • EPA Region – Select one of EPA’s 10 regions. For information on the geography covered by each region, as well as to access regional cleanup web pages, see the Cleanups Where You Live page.
  • Watershed – You can select the hydrological unit code, catalog unit name or sub-region name. Catalog units are also called watersheds. An explanation of these terms is provided on the USGS HUC pageExit. Listings of these geographic areas are also available at the USGS websiteExit.
  • Tribal areas – We use the Tribal Boundaries from the EPA Map service ( which "is built by combining boundaries from the 2010 Census American Indian/Alaska Native/Native Hawaiian Areas (AIANNH) data (visit for details) with Federally recognized Tribal Entity Names as provided by EPA's Tribal Identification web service (found at".  To view the tribal areas disclaimer, please see our Legal Notices.
  • Latitude/Longitude – When you specify a specific point, and a radius around that point, the map will show that area and all the cleanups that appear on the map. The listing will include only those cleanups within the specified radius of that point. Site Names correspond to the names of cleanups in CIMC. Latitude and longitude need to be specified in decimal degrees.
  • Department of Energy Legacy Management Sites – The U.S. Department of Energy Office of Legacy Management (LM) is the caretaker of sites that played a critical role in America’s nuclear history. Ranging from Alaska to Puerto Rico, LM's 100 sites supported the Manhattan Project during World War II and nuclear weapons and technology during the Cold War. It's important to LM that members of the public have access to the information they need to be confident in the safety of DOE sites. DOE is committed to transparently sharing information, including geospatial layers, dynamic mapping, and environmental monitoring data. DOE provides analytical chemistry data, groundwater depths and elevations, well logs, well construction data, georeferenced boundaries, sampling locations, and photographs. For more information about DOE LM, visit Exit

Please note that when you map cleanups, the map view will show all cleanups, including those outside the specified geography. When you list the cleanups, only those cleanups in the specified geography will be included. This is why a comparison of the cleanups mapped and those listed for the same geography will not be exactly the same.

Census Geography

Brownfields profiles include additional local Census data based on Blocks and Block Groups. Several Blocks make up a Block Group. Census statistics are available for Block Groups, but only population and household counts are available for Blocks. We identify all Blocks where the geographic center of the Block is within n miles of a Brownfields property. The Blocks with geographic centers within the radius may make up only a portion of a Block Groups. In that case, we weight census statistics based on the population of the selected Blocks divided by the population of the entire Block Group. Data are sourced from U.S. Census for the decennial census when it becomes available and yearly updates through the American Community Survey (ACS).
