U.S. Superfund Sites Map

Superfund sites are the most seriously contaminated places in the United States, the ones the Environmental Protection Agency has flagged for long-term federal cleanup. This interactive map plots all 1,840 sites on the EPA’s National Priorities List so you can see which ones are near you, what their status is, and how they scored on the EPA’s hazard ranking.

Use your location or type an address, city, or ZIP code to see the closest sites ranked by distance, each with its status and hazard score. Filter by state or by status, click any site for its full detail, and open the EPA’s own page for the contaminants and the current cleanup progress. Every view has a shareable link.

The map is honest about what it shows. The National Priorities List is the federal priority list, not a list of every contaminated place, a “Deleted” site is one that has been cleaned up and removed, and each marker is the EPA’s approximate point for a site rather than its full footprint. The data is public domain and date-stamped.

How to use the Superfund sites map

1. Allow location access, or type an address, city, or ZIP code, to center the map on you.
2. Read the nearest Superfund sites list, sorted by distance, with each site’s status and hazard score.
3. Use the status filter to show only sites that are on the list, proposed, or cleaned up and removed, and the state dropdown to focus on a single state.
4. Toggle “Cleanup built” to show only the sites where the physical cleanup construction is complete.
5. Click any site marker or list row to open its details, then follow the link to its EPA site profile for the contaminants and current status.
6. Use the Share button to copy a link to your exact map view and filters.

About the data

The map uses the U.S. EPA’s public “Superfund National Priorities List (NPL) sites with status information” dataset, the same source behind the EPA’s Superfund: Where You Live map. It is a U.S. Government work in the public domain. The coordinates come from each site’s Hazard Ranking System documentation.

It covers 1,840 sites across 57 states and territories: 1,343 that are currently on the list, 37 proposed for it, and 460 that have been cleaned up and removed. Of these, 1,248 have reached construction completion, meaning the physical cleanup has been built. The data shown here is dated 2026-05-12; the EPA revises the list by Federal Register rule a few times a year, and the map footer always shows the current date.

Each site carries its status, its Hazard Ranking System score, its city, county, and state, and the dates it was proposed, added, cleaned up, or removed. The hazard score is a 0 to 100 screening number from the time of listing, not a live risk measurement. This dataset does not list the specific contaminants at a site, so the detail card links to the EPA’s own site page, which has the contaminants, the site boundary, and the latest cleanup status.

Important note

This map shows sites on or proposed for the U.S. EPA’s Superfund National Priorities List, the federal list of the most serious hazardous-waste sites, using the EPA’s public data. It is for general information only. It is not health, safety, legal, or real-estate advice. The National Priorities List is not a list of every contaminated place: it is the federal priority list, and thousands of other contaminated sites are handled by state programs, brownfields, and other authorities and are not shown here, so the absence of a nearby site does not mean there is no contamination near you. Each marker is the EPA’s official point location for the site, which can be approximate and does not show the true size of the contaminated area. A “Deleted” site was removed from the list after cleanup goals were met. This dataset does not include the specific contaminants at a site: use the EPA site profile link for that and for the current status. To understand risk where you live, read the linked EPA site page and contact the EPA or your state environmental agency.

Frequently asked questions

What is a Superfund site?

A Superfund site is a place that the U.S. Environmental Protection Agency has identified as being contaminated with hazardous substances and serious enough to need long-term federal cleanup. The name comes from the 1980 Superfund law (CERCLA). The most serious of these sites are placed on the National Priorities List, and those are the sites shown on this map.

What is the National Priorities List (NPL)?

The National Priorities List is the EPA’s list of the hazardous-waste sites that qualify for federal Superfund cleanup. A site is added when its Hazard Ranking System score reaches 28.50 or higher. This map plots all 1,840 sites that are on, proposed for, or have been removed from the list.

Where does this data come from and how current is it?

The map uses the EPA’s public “Superfund National Priorities List (NPL) sites with status information” dataset, the same data behind the EPA’s own Superfund: Where You Live map. It is in the public domain. The version shown here is dated 2026-05-12, which is noted in the footer of the map. The EPA revises the list by Federal Register rule a few times a year.

How do I find Superfund sites near me?

Allow location access, or type your address, city, or ZIP code into the search box. The map centers on you and lists the nearest Superfund sites in order of distance, each with its status and hazard score. You can then click any site for more detail and a link to its EPA page.

What do the site statuses (final, proposed, deleted) mean?

“On the Superfund list (Final NPL)” means the site is an active federal Superfund site. “Proposed” means the EPA has proposed adding it but has not finalized that yet. “Cleaned up and removed (Deleted)” means the site was taken off the list after its cleanup goals were met.

Does a “deleted” site mean it is safe now?

A deleted site was removed from the National Priorities List because the EPA determined that the planned cleanup was complete and the goals were met. That is good news, and it is why deleted sites are shown in green. Some sites are only partly deleted, and in rare cases a site can be re-listed, so the linked EPA site page is always the authoritative source for the current status.

What is the HRS site score?

The Hazard Ranking System score is the 0 to 100 screening score the EPA used to decide whether the site qualified for the list. A site needs a score of at least 28.50 to be listed, and a higher score meant a higher ranked hazard at the time of listing. It is a listing-era screening number, not a measure of the current risk to someone living nearby.

Does this map show every contaminated site near me?

No. The National Priorities List is the federal priority list of the most serious sites only. Thousands of other contaminated sites are handled by state cleanup programs, RCRA corrective action, and brownfields programs and are not on this map. If there is no Superfund site near you, that does not mean there is no contamination nearby.

What contaminants are at a Superfund site?

This dataset carries each site’s status, hazard score, and key dates, but not the specific contaminants. To see what was found at a site and the current cleanup status, open the site’s EPA profile using the link in its detail card.

How accurate are the site locations?

Each marker is the EPA’s official point coordinate for the site, taken from the Hazard Ranking System documentation. It can be approximate and it does not show the true size of the contaminated area, which for some sites can cover many square miles or a long stretch of a river. Use the EPA site page for the real site boundary.
