Key Takeaways
- EPA has proposed lower lead cleanup levels: The proposal would cut the soil level from 350 to 240 ppm and the indoor dust level from 275 to 110 ppm (EPA, September 2026).
- It is still a proposal: EPA extended written comments through October 15, 2026. As of October 19, 2026, EPA had not posted a final decision.
- Earlier results may be looked at again: EPA says houses sampled earlier that did not meet the old threshold will be reevaluated. Yards that already had whole-yard cleanups are not expected to be revisited.
- Check your address first: EPA's Property Status Dashboard shows whether a house in the residential study area was sampled or cleaned. Keep your EPA letters, because EPA says you may need them to sell or refinance.
- Disclose what you know: Colorado's SPD19 form requires known adverse material facts, and pre-1978 houses carry the federal lead-based paint disclosure.
- Three honest paths: Wait for sampling and cleanup, list now with full disclosure, or sell as-is for cash. Time and the rest of the house usually decide which fits.
If you own a house near the Colorado Smelter Superfund site in Pueblo, Colorado, you can sell it. The site covers parts of Bessemer, Eilers, and the Grove, and EPA has worked there for over a decade. In September 2026, EPA proposed a lower lead cleanup level that could bring more yards into the cleanup program.
This guide covers what EPA has said, where to check your address, what you must disclose, and how three ways to sell compare. For health questions, it points you to EPA and the Pueblo Health Department.

Let's chatWhat Is the Colorado Smelter Superfund Site in Pueblo?
The Colorado Smelter Superfund site in Pueblo is the area around a former silver and lead smelter that ran in the Eilers and Bessemer neighborhoods from 1883 to 1908. EPA says that "high levels of lead and arsenic have been identified in yards and inside homes within the study area" (EPA Colorado Smelter page, July 2026). EPA added the site to the National Priorities List in December 2014.
EPA's background page describes the old smelter footprint as bounded by Santa Fe Avenue, Mesa Avenue, Interstate 25, and the Arkansas River. The Bessemer, Eilers, and Grove neighborhoods sit next to it (EPA Background page, February 2026). The active steel mill is not part of the Superfund site.
The neighborhoods involved
The City of Pueblo's revitalization plan names "our neighborhoods of Bessemer, Eilers Heights in Bojon Town, and the Grove" as the ones around the site (City of Pueblo, Colorado Smelter Revitalization). EPA's residential study area covers the Grove, Eilers, and parts of Bessemer. Being in one of those neighborhoods does not by itself mean a given yard tested high.
Two parts of the site
EPA splits the site into two operable units. Operable Unit 1 covers houses, alleys, businesses, parks, and schools. Operable Unit 2 is the former smelter area and nearby undeveloped land.
For a house seller, Operable Unit 1 is the part that matters. EPA counts about 2,030 residential addresses there, and 95 percent of the houses in the study area were built before 1978 (EPA Site Progress page, April 2026; EPA Background page, February 2026).
What EPA has already done
EPA finished sampling and cleaning houses under the current cleanup level in 2025. Among the houses whose owners gave access, EPA reports this work (EPA Site Progress page, April 2026):
- Soil sampling at 1,973 houses
- Soil cleanup and yard restoration at 813 houses
- Indoor dust sampling at 1,817 houses
- Indoor dust cleanup at 568 houses
What Did EPA Propose in September 2026?
On September 1, 2026, EPA proposed lowering the Colorado Smelter lead cleanup levels to 240 ppm for residential soil and 110 ppm for indoor dust (EPA news release, September 2026). The proposal follows EPA's October 2025 residential soil lead directive. It would change the site's 2017 Interim Record of Decision through a document called an Explanation of Significant Differences.
| Measure | Current level (2017 Interim Record of Decision) | Proposed level (September 2026) | Source |
|---|---|---|---|
| Lead in residential soil | 350 ppm | 240 ppm | EPA news release, September 1, 2026 |
| Lead in indoor dust | 275 ppm | 110 ppm | EPA news release, September 1, 2026 |
| Arsenic in soil and indoor dust | 61 ppm | No change named in the release | EPA Site Progress page, April 2026 |
| Status | In effect | Proposed; comments closed October 15, 2026 | EPA Announcements page, October 2026 |
What the proposal could mean for your house
EPA says houses sampled earlier that did not meet the former threshold will be reevaluated under the new levels. A yard that tested below 350 ppm in an earlier round could qualify under a 240 ppm level. EPA does not expect to revisit yards that already had a whole-yard cleanup.
EPA also says residential sampling remains available while the proposal is reviewed and finalized. If your house was never sampled, you can still ask for sampling now.
Where the decision stands
The release first set a 30-day comment period from September 1 to October 1, 2026. EPA's announcements page later extended written comments through October 15, 2026 (EPA Announcements page, October 2026). EPA says it will answer all comments in a responsiveness summary within the final document.
As of October 19, 2026, EPA had not posted a final decision on its Colorado Smelter pages. EPA's cleanup schedule lists the Explanation of Significant Differences with an estimated window of August to November 2026, and EPA notes that schedule dates can change (EPA Cleanup Schedule, July 2026). Check the announcements page before you make a decision that depends on the final numbers.
How to Check Your Sampling and Cleanup Status
The fastest way to check your house is EPA's Colorado Smelter Property Status Dashboard, which shows whether a house in Operable Unit 1 has been sampled or cleaned. EPA warns that the dashboard can take a minute or two to load. It is the same record a buyer or a lender can look up.
Find your EPA letters
EPA mails owners letters with sampling results and cleanup confirmations. EPA's site progress page says: "Please keep a copy of the sampling or cleanup letters EPA provides. You may need them to sell or refinance your property." If you cannot find yours, the same page lists an EPA community contact who can send copies.
Heirs often run into this step, since a parent may have filed the letter away years ago. If you are settling an estate, our guide to selling an inherited house in Pueblo covers probate and the vacant house fee. Add the EPA letter to the paperwork you gather.
If your house was never sampled
EPA reports that some owners denied access during earlier rounds. If your house has no sampling record, use the contact form on EPA's Colorado Smelter page to ask about sampling. A result in hand, either way, gives you something concrete to disclose.
EPA's community page says residents of the Superfund site can get free blood-lead testing through the Pueblo Health Department lead program, and EPA lists the number (719) 583-4307. For questions about your family's health, start there or with your doctor.
Pueblo Lead Cleanup: Cost, Access, and Timing
EPA carries out the Pueblo lead cleanup, and its site page cites a policy that EPA "will generally not cost recover against residential property owners" (EPA Site Progress page, April 2026). EPA notes that this policy does not cover non-residential parcels in the former smelter area. If you own a commercial lot, the rules differ, and EPA publishes a separate fact sheet for those owners.
Access comes first
EPA can sample and clean only the houses whose owners give access. Its own counts show the gap. EPA reports that 3 percent of owners denied access for soil sampling and 5 percent for soil cleanup (EPA Site Progress page, April 2026).
If EPA contacts you about access, read the paperwork and ask questions before you sign. If you plan to sell, ask EPA how a pending sampling or cleanup is handled when the house changes hands. EPA's pages do not address that question, so get the answer from EPA directly.
What a cleanup involves
Under the 2017 plan, EPA removes and replaces contaminated soil and cleans indoor dust where needed, then restores the yard. EPA sets that schedule, not your sale date.
What Do You Have to Disclose When You Sell?
You have to disclose what you actually know about the house, including EPA sampling results and cleanup records, even though Colorado's standard seller form does not name the Superfund site. Two separate rules apply: Colorado's seller disclosure form and the federal lead-based paint disclosure for older houses.
Colorado's SPD19 form
The Colorado Real Estate Commission's Seller's Property Disclosure (SPD19) became mandatory for use on January 1, 2026. Its environmental section does not mention Superfund by name. It does ask whether you know of any of these at the house:
- Hazardous materials, including toxic materials
- Environmental assessments, studies, or reports
- Other environmental problems, issues, or concerns
A separate section asks for copies of written soils reports in your possession. The form also states that a known adverse material fact "must be disclosed whether there is a specific item on this SPD or not." It adds that failing to disclose one "may result in legal liability."
The form is limited to your "current actual knowledge," and it says the seller has no duty to investigate. If you hold an EPA letter, you know what it says. Put it on the form and attach a copy.
The federal lead-based paint disclosure
EPA reports that 95 percent of houses in the study area were built before 1978. Federal law (42 U.S.C. 4852d) and EPA's rule at 40 CFR Part 745, Subpart F set the steps for selling pre-1978 housing. Before the buyer is bound by the contract, the seller must:
- Give the buyer the EPA pamphlet Protect Your Family From Lead in Your Home (40 CFR 745.107)
- Disclose any known lead-based paint or lead-based paint hazards
- Provide available records or reports about them
- Allow a 10-day window for a lead inspection or risk assessment, unless the buyer waives it in writing (40 CFR 745.110)
- Attach the Lead Warning Statement and signed certifications to the contract (40 CFR 745.113)
The federal definition of a lead-based paint hazard reaches lead-contaminated dust and lead-contaminated soil, not just paint (40 CFR 745.103). Ask a Colorado real estate attorney whether your EPA soil and dust results belong on the records list. Sharing them is the cautious course.
Selling as-is means you are not agreeing to make repairs or arrange a cleanup. It does not mean the disclosure forms can stay blank. Full disclosure protects you after closing, and a buyer who prices the house up front has less reason to come back later.
How Cleanup Status Can Affect a Financed Buyer
A financed buyer's lender and appraiser may ask about the Superfund status, and a clear EPA letter is the simplest answer you can give them. EPA itself published a case study on the topic, titled Reducing Lending Challenges During Residential Cleanups: The Colorado Smelter Superfund Site Case Study (EPA Redevelopment page, April 2026).
EPA's summary says a Superfund listing can add stigma at first, but it also gives clear information about which houses were sampled and where cleanup happened. Your letter turns a vague worry into a documented fact.
Where questions can come up
In general terms, a financed sale has more people who may want answers:
- The buyer's inspector may flag older paint or bare-soil yards.
- The lender may ask for the EPA record before closing.
- A buyer with young children may want the 10-day lead inspection window.
None of these stops a sale on its own, but each can add time or prompt a renegotiation. A completed cleanup letter and a full disclosure packet can give a financed buyer fewer reasons to pause.
Pueblo's pace overall
Pueblo is not a fast market to begin with. The median sale price was $260,676 over the three months ending September 2026, and the median house sold after 62 days on the market (Redfin, September 2026). Our Pueblo housing market 2026 report breaks down the citywide numbers. Questions about the EPA record add to that baseline.
Selling a House in Bessemer, Pueblo: Three Paths
Selling a house in Bessemer, Eilers, or the Grove comes down to three paths: wait for sampling and cleanup and then list, list now with full disclosure, or sell as-is for cash. The right one depends on your timeline, your EPA record, and what else the house needs.
| Path | Best fit | Timing | Trade-offs |
|---|---|---|---|
| Wait for sampling and cleanup, then list | A cleanup looks likely, you can hold the house, and it is otherwise in good shape | Set by EPA's final decision and cleanup schedule, then a normal listing | Clean record for buyers, but months of carrying costs and an uncertain start date |
| List now with full disclosure | Your EPA record is clear or the yard was already cleaned, and the house is list-ready | A typical Pueblo listing timeline (62 median days on market, Redfin, September 2026) | Agent commissions, showings, inspection requests, and possible lender questions |
| Sell as-is for cash | You need certainty, the house needs other major work, or you are settling an estate | Can close in as few as 7 days, on a date you choose | The buyer prices the house as it stands, including the EPA record |
Wait for sampling and cleanup, then list
If an EPA cleanup looks likely for your yard and you have time, waiting may help. A completed cleanup letter answers the first question a financed buyer will ask. The cost is time, since you carry taxes, insurance, and utilities while EPA finalizes the new level and schedules work.
List now with full disclosure
If your house needed no cleanup, or the yard was already cleaned, listing now can work well. Gather your EPA letters, complete the SPD19 and lead-based paint forms, and share the packet early.
Sell as-is for cash
An as-is sale fits when the EPA question is one of several. EPA reports that nearly all houses in the study area were built before 1978, and some may need roofs, wiring, or plumbing as well. Our guide to selling an older North Side or Mesa Junction house in Pueblo covers that older-house picture. You can also read about selling a house that needs major repairs.
Sell a House As-Is in Pueblo for Cash
When you sell a house as-is in Pueblo for cash, the EPA record becomes one line in the offer instead of a hurdle for a lender. There is no lender appraisal and no wait for a loan to clear underwriting. You disclose what you know, hand over your letters, and the buyer prices the house as it stands.

Let's chatFrequently Asked Questions
How do I find out if EPA sampled or cleaned my Pueblo house?
You can find out whether EPA sampled or cleaned your Pueblo house by checking EPA's Colorado Smelter Property Status Dashboard, which shows sampling and cleanup status for residential addresses in Operable Unit 1. If the dashboard is unclear, use the contact form on EPA's Colorado Smelter page. EPA also asks owners to keep copies of their sampling and cleanup letters, since you may need them to sell or refinance.
Has EPA finalized the lower lead cleanup level for the Colorado Smelter site?
EPA had not posted a final decision on the lower Colorado Smelter lead cleanup levels as of October 19, 2026, when this article was last checked. The proposal would lower the residential soil level from 350 ppm to 240 ppm and the indoor dust level from 275 ppm to 110 ppm. EPA extended the written comment period through October 15, 2026, and says it will answer comments in a responsiveness summary.
Do I have to disclose that my house is near the Colorado Smelter Superfund site when I sell?
You have to disclose what you actually know about lead in your soil or dust when you sell, even though Colorado's SPD19 form does not name the Superfund site. The form asks about hazardous materials, environmental reports, and other environmental concerns, and says any known adverse material fact must be disclosed. For a house built before 1978, federal law also requires the lead-based paint disclosure and pamphlet.
Does an EPA yard cleanup in Pueblo cost the homeowner anything?
EPA says it will generally not seek to recover cleanup costs from residential owners at Superfund sites, under an enforcement policy cited on its Colorado Smelter site page. EPA notes that this policy does not apply to non-residential parcels in the former smelter area. For questions about your own address, contact EPA through the site page before you assume anything.
Can I sell a house in Bessemer as-is before EPA samples or cleans it?
You can sell a house in Bessemer as-is before EPA samples or cleans it, because no rule requires a cleanup before a sale. EPA's pages do not say how a sale changes a pending sampling or cleanup, so ask EPA before you sign. Disclose what you know, hand over any EPA letters, and let the buyer price the house as it stands.
Should I wait for the EPA cleanup before selling my Pueblo house?
Waiting for the EPA cleanup before selling your Pueblo house can make sense when a cleanup is likely and you have time to hold the house. A completed cleanup letter gives a financed buyer a clear answer. If you need to sell sooner, or the house needs other major repairs, listing with full disclosure or selling as-is for cash may fit better.
