Which lawsuits does Teton Intake cover?
Each topic has its own page. It explains what the lawsuit is about and whom it may concern. It also shows which records matter and how to compare them with your own situation.
Below each topic are pages for specific situations. Depending on the lawsuit, that can be a place, a product and how long it was used, or a job.
About from firefighting foam (). Pages built around the sites the contamination is traced to. So far there are three. Peterson Air Force Base is in Colorado. The Willow Grove and Warminster bases are in Pennsylvania. Fairchild Air Force Base is in Washington. Each shows which water systems were affected, what was measured, and when treatment began.
About PFAS in the protective clothing firefighters wear. What the lawsuits claim, what courts have decided so far, and what research shows about the gear.
The list is short on purpose. A topic goes up only when its court orders and records can be read, checked, and linked.
What does “plain language” look like here?
Here is one example from the PFAS lawsuits. It covers personal injury cases in the firefighting-foam lawsuits. It shows what proof the court asks for once a case is filed. First the court's own wording, then what it means.
“A plaintiff alleging exposure to PFAS through drinking water served by a public water system and/or a private well shall provide any evidence of PFAS contamination in the drinking water … A plaintiff alleging exposure via a public water system shall also provide the public water system identification number (“PWSID”) and/or name for such water system/s.”
If you say your drinking water exposed you to PFAS, you need some evidence that PFAS was in that water.
This passage asks for “any evidence” and names no minimum level. That does not mean any trace makes a strong claim.
If the water came from a public system, you also need its ID number () or its name.

How can you check whether a lawsuit could concern you?
- Pick your topic. Read what the lawsuit is about and whose claims it covers.
- Find your situation. Open the page that fits you — where you lived, a product you used, or a job you had. Then compare it with your own history.
- Talk to an attorney. If it seems to fit, bring what you found. Only an attorney can judge whether a claim is viable.
Nothing here signs you up for anything. There are no forms.
Why does Teton Intake exist?
Sometimes similar lawsuits are filed all over the country. A panel of federal judges can then send them to one court for their pretrial proceedings. This is called an .
That court's orders can spell out what proof each claim needs — as in the example above. The orders are public. But they are long and written for lawyers.
Teton Intake reads them, together with the public records a claim may depend on. We explain both in plain language.
We don't make the rules, and we don't judge anyone's case. Court orders set out what proof a case needs. An attorney decides whether your case is viable. Our aim is simple: your first talk with a lawyer should start from facts, not from a sales pitch.
Who is behind Teton Intake, and how is each page checked?
Teton Intake is written by Stefan. He has worked in the pharmaceutical industry since 2009. Today he works in quality assurance for engineering and systems in -regulated manufacturing. Before that, his university thesis was in cancer research. He set up a yeast-based test to screen for compounds that block certain enzymes.
In quality assurance, every claim must trace back to a documented source. Review is a documented step, not a courtesy. Stefan is not a lawyer and not a physician — which is why every page points you to both.
Every page follows one rule: each claim about a lawsuit or dataset links to its source, right where it is made. tools help with research and drafts. Stefan reviews, fact-checks, and approves every page before it goes live.
Teton Intake is an independent publisher. It is not a law firm, a doctor's office, or a government agency. Teton Intake is funded entirely by Stefan. It currently receives no money from anyone else. If this site ever asks you for information, that page will say what happens to it before you type anything.
Where does the information come from?
-
The requirements, deadlines, and procedures of each lawsuit. Public via , and on some courts' own websites.
-
Official case counts and status of consolidated federal lawsuits.
-
Government datasetsTest results, agency records, and registries. Each topic page names its datasets and links them where a figure appears.
-
Health researchPeer-reviewed studies and expert reports, linked where cited — including work that questions earlier findings.
We don't rule sources in or out by who published them. A source is used if it survives review: Is the method transparent? Can the finding be traced? Does it hold up against the primary records? A government dataset gets checked the same way as an industry study. Where the evidence is contested or unsettled, we say so instead of picking a side for you.
