The presumption stops at 12 nautical miles, not at the waterline. Offshore crews drank distilled seawater, and old denials can still be paid back to the original claim.
For more than a decade the VA drew its line at the waterline. If your boots never touched Vietnamese soil, you were told you were never exposed, and the presumption that covered the man standing on the beach did not cover the man standing on the deck two miles out. That reading was upheld in Haas v. Peake, 525 F.3d 1168 (Fed. Cir. 2008), and it shut the door on an entire generation of sailors and Coast Guardsmen for eleven years.
The door was reopened twice. In Procopio v. Wilkie, 913 F.3d 1371 (Fed. Cir. 2019), decided en banc on January 29, 2019, the Federal Circuit held that when Congress wrote *the Republic of Vietnam* it meant the country including its territorial sea, not just its dry land. Congress then wrote the answer into statute with the Blue Water Navy Vietnam Veterans Act of 2019, Public Law 116-23, signed June 25, 2019 and effective January 1, 2020, now codified at 38 U.S.C. § 1116A. The exposure was never in doubt. What was in doubt was whether anyone would admit it.
What you were actually breathing, drinking, or touching
Agent OrangeTCDD dioxin2,4-D2,4,5-TAgent Blue — cacodylic acidAgent White — picloramDistilled ship drinking water
Presumptive route available
Full presumption. Service in the offshore waters of Vietnam out to 12 nautical miles between January 9, 1962 and May 7, 1975 is exposure as a matter of law under 38 U.S.C. § 1116A.
Where it was, when it was, and who was standing there
The exposure, in specifics
A claim is decided on specifics. Location, date range, and duty — in that combination — are what turn an assertion of exposure into a documented one.
The 12 nautical mile line
The statute reaches the offshore waters of Vietnam out to 12 nautical miles seaward of the demarcation line of the waters of Vietnam and Cambodia, for service between January 9, 1962 and May 7, 1975. Inside that line, the presumption applies the same way it applies to a soldier ashore. It is a position question, not a hull-number question — and position is a matter of record.
The evaporators — how it actually reached the crew
Ships at sea made their own fresh water by boiling seawater and condensing the steam. Distillation is designed to strip salt. It does not strip dioxin the same way, and work commissioned by the Australian government found the process could concentrate it rather than remove it. The National Academies reviewed the pathway in 2011. That is the route: a sailor who never went ashore still drank it, cooked with it, showered in it, and made coffee with it, every day, for the length of the cruise.
Every rate aboard, not only the snipes
The evaporators sat in the engineering spaces, but the water went everywhere: the scullery, the galley, the showers, the sick bay, the scuttlebutt on every deck. A cook, a radioman, a yeoman, a hospital corpsman and a boatswain’s mate all drank from the same tanks. There is no rate on a ship that was drinking different water, and there is no requirement in § 1116A that you worked below decks.
Ports, harbours, and anchorages
Da Nang, Cam Ranh Bay, Vung Tau, Nha Trang. Ships moored, anchored, and took on stores well inside the line. A single day at anchor inside those waters is inside the statute, and the deck log for that day says so in the ship’s own hand.
Coast Guard on Operation Market Time
Coast Guard cutters and patrol boats ran coastal interdiction under Operation Market Time, working the shallows and the river mouths. Coast Guard service counts the same as Navy service here. Cutter crews are among the most frequently overlooked claimants in this entire population.
Brown water was never the argument
Service on the inland waterways — the Mekong Delta, the rivers, the canals — was always covered, and still is. The dispute was only ever about the ships offshore. If you served on a river patrol boat, a swift boat, or a landing craft in the delta, you are not in the Blue Water fight at all; you are inside the original presumption under 38 CFR 3.307(a)(6)(iii), which has stood since 1991. That is a different regulation with a different date and a different evidence problem, and it has its own file on this site.
Served on the rivers?
Brown Water Navy has its own file.
River patrol boats, swift boats, and the Mobile Riverine Force were covered by the inland waterway presumption from 1991 — a different regulation, a different date, and a different evidence problem than the offshore rule. The task forces, the riverbank spraying, and the unit records that stand in for a deck log are set out on their own page.
The herbicide itself, the ground and air operations, Thailand, the Korean DMZ, the storage and test sites, and the same 38 CFR 3.309(e) condition list read from the shore side rather than the water.
Work out which route your case is on before you gather a single document. Preparing the wrong evidence is the most common reason a truthful claim comes back denied.
Presumptive route
Presumptive service connection — offshore service
Two facts and a diagnosis. One — the ship operated inside 12 nautical miles of Vietnam during the window. Two — you were aboard. Three — you carry a condition on the 38 CFR 3.309(e) list. Meet those and the VA concedes exposure. You are not required to prove that dioxin was in the water on the day you drank it, and you are not required to prove the ship sprayed anything.
The location rule lives at 38 CFR 3.307(a)(6); the condition list lives at 38 CFR 3.309(e).
There is no manifestation deadline. A prostate cancer diagnosed in 2024 is as presumptive as one diagnosed in 1984.
VA maintains a list of Navy and Coast Guard ships associated with service in Vietnam. That list is a convenience, not the boundary of the law.
Facts-found route
Facts-found — off the list, or outside the line
If your ship is not on VA’s list, that is an evidence problem, not a legal problem: the deck logs at the National Archives record the ship’s position, and they settle it. If your diagnosis is not on the 3.309(e) list, the presumption does not reach it — but a facts-found claim still can, built on the exposure evidence plus a medical opinion connecting the two. No presumption is not the same as no claim.
Deck logs, the ship’s command history report, and muster rolls are held at the National Archives and can be requested.
A facts-found claim needs a nexus opinion that reads *at least as likely as not* and explains the mechanism, not a form letter.
A ship that was never listed but sat in Da Nang harbour for nine days is proven by paper, not by argument.
Secondary route
Secondary conditions — what the presumptive disease caused
The presumptive disease is the doorway, not the whole house. Diabetes drives neuropathy, retinopathy, and kidney disease. Ischemic heart disease drives the workload limits that support Total Disability based on Individual Unemployability. Prostate cancer leaves urinary and erectile residuals that are rated separately once the active treatment ends. Files that claim the headline condition and stop are the most common form of money left behind.
Diabetes to peripheral neuropathy, diabetic retinopathy, and chronic kidney disease.
Prostate cancer to voiding dysfunction, urinary frequency, and erectile dysfunction with special monthly compensation.
Ischemic heart disease to the METs limits that carry a TDIU argument.
Two different things — never combine them
A presumption and a TERA determination are not the same thing
These two get mixed together constantly — by veterans, by service officers, and sometimes in the decision letter itself. They are separate mechanisms that answer separate questions. One asks where and when you served. The other asks what you did while you were there. Treating either one as a substitute for the other is how a winnable claim gets prepared the wrong way and comes back denied.
Here is the fastest way to tell which lane you are standing in. A presumption almost always comes out of a deployment or an assignment to a place that has already been named — Vietnam, the Gulf, the Korean DMZ, the burn-pit countries, Camp Lejeune. Congress or VA drew a box around a region and a set of dates, and if your service falls inside that box and your diagnosis is on the list attached to it, you are in the presumptive lane and the law does the connecting for you. TERA is for everything else. If your exposure did not come from being sent to one of those named locations — if it came from the aircraft you turned wrenches on, the fuel you pumped, the foam you sprayed, the paint and solvent you stripped with, the engine room you stood watch in, the stateside installation where the work itself was the hazard — then no list is ever going to carry your claim. That is a TERA case, and it is proved with your duties.
Read both columns before you decide what to gather. If you are in the presumptive lane, the work is proving your service facts — orders, dates, locations. If you are in the TERA lane, the work is documenting what you actually did and then getting a medical opinion that ties it to the diagnosis. Those are two entirely different piles of paper, and preparing the wrong one costs months. And plenty of veterans are standing in both lanes at the same time — one condition that qualifies off a deployment, another that only ever gets connected through the work.
Set by law — where and when you served
A presumption
A presumption is written into statute and regulation. It has three moving parts and all three have to line up: a specific place, a specific date range, and a diagnosis that appears on the list attached to that place. When they do, VA presumes the exposure and presumes the connection — you never have to produce a medical opinion tying the disease to the service.
It is decided on service records, not on medical evidence.
Miss the location or the date window by anything at all and the presumption simply does not apply.
The condition list is closed — a diagnosis that is not on it is not presumptive, however strong the science behind it.
If you do qualify, it is the fastest route to a decision that exists.
Based on what you actually did
A TERA determination
TERA stands for Toxic Exposure Risk Activity. It is VA’s finding that your service involved an activity that put you at risk of a hazard, and it comes out of your duties, your assignments, and the work you actually performed — not out of a list of places and dates. It is not a presumption, and on its own it does not grant service connection.
What it does: it puts the exposure into the record, and under 38 U.S.C. § 1168 it generally obligates VA to obtain an exam and a medical opinion when there is a current disability and the file is otherwise short of proof.
What it does not do: it does not concede the medical link. VA can find TERA and still deny the claim for “no nexus.”
It is also used on the health care side, to establish eligibility to enroll and to get the toxic exposure screening.
It is frequently missing from the file, or built off your primary job code alone — which misses the duties that actually exposed you.
Keep them apart — four rules that decide claims
No presumption does not mean no claim. It means your claim is facts-found, and the link gets built with evidence instead of handed to you by regulation.
A TERA finding is not a presumption. It never removes the need for a nexus opinion — it is what forces VA to go get one.
You can be in both lanes at once. Presumptive on one condition and facts-found on another, inside the same application.
Serving somewhere with a documented hazard is not the same as qualifying for a presumption. The presumption needs the exact place, the exact dates, and a listed condition — all three.
The condition lists
What is on a list, and what is not
Read the label above each list carefully. A presumptive list and a health-care eligibility list are two different things, and confusing them costs veterans claims every single day.
Presumptive conditions — disability compensation
The herbicide list at 38 CFR 3.309(e). Diagnosed at any time after service. There is no manifestation deadline on this list.

Bladder cancer
Chronic B-cell leukemias, including hairy cell leukemia
Chloracne or similar acneform disease
Type 2 diabetes mellitus

Birth defects in children of exposed veterans
A separate program under 38 CFR 3.814 and 3.815, filed by or for the child rather than on the veteran’s own claim. Whether offshore service alone opens that program is a question to put to an accredited representative — the wording of those regulations is not the wording Congress used in § 1116A.

How to apply
The filing order, with the actual forms
Order matters. Filing in the wrong sequence is how veterans lose months of back pay on a claim that was always going to be granted.
1
VA Form 20-0995
If you were ever denied before, start here
The Supplemental Claim is the form that reopens a file closed under the old Blue Water rule, and it is the form that carries the Nehmer effective-date question. Filing a brand-new claim instead can quietly cost you every year between the old denial and today.
2
VA Form 21-526EZ
If you have never filed, file the claim
The Application for Disability Compensation. List every diagnosed condition, not only the one you think is strongest, and name the ship and the dates you were aboard.
3
SF-180
Request the deck logs and the ship records
Deck logs, muster rolls, and command history reports are held at the National Archives. This is the paper that puts the ship inside 12 nautical miles on a specific date, and it is what wins a file when the vessel is not on the VA list.
4
VA Form 21-534EZ
For survivors
The application for Dependency and Indemnity Compensation, survivors pension, and accrued benefits. This is the right form when the veteran has died — including when he was denied years ago under the rule that no longer exists.
5
VA Form 21-4142
Authorise the private records
The release that lets the VA collect civilian oncology, cardiology, and endocrinology records. Most Blue Water treatment happened outside the VA system, which means the strongest evidence is usually sitting in a private chart.
6
VA Form 21-22a
Appoint an accredited representative
This file turns on effective dates and archival records, not on adjectives. Appointing an accredited agent or attorney puts someone on the file who can request the logs, read the old denial, and argue the Nehmer date. We do not give claim strategy on this page — that conversation belongs with your representative.
Evidence to gather
What belongs in the file before you file
DD-214 showing Navy or Coast Guard service inside the January 9, 1962 to May 7, 1975 window.
Personnel record showing which ship you were assigned to, and the dates you were aboard.
Deck logs from the National Archives for the dates in question — they record the ship’s position and are the single strongest document in this claim.
The ship’s command history report or cruise book, which places the vessel on station by month.
VA’s Navy and Coast Guard ships list, if your vessel appears on it — a shortcut, not a requirement.
The original denial letter and its date. On a Blue Water file this piece of paper is often worth more than everything else combined, because it is what the retroactive effective date is measured from.
A current diagnosis, in writing, from any credentialed physician.
Treatment records showing how long the condition has been under care.
What you will be told, and the answer
The shortcuts to expect
“"You were Blue Water Navy, so the presumption does not apply to you."”
That rule was repealed. 38 U.S.C. § 1116A restored the presumption out to 12 nautical miles, effective January 1, 2020, after *Procopio* held that the Republic of Vietnam always included its territorial sea. Anyone still applying Haas is applying a case that no longer controls.
“"Your ship is not on the VA list, so we cannot concede exposure."”
The list is an administrative convenience the VA built for itself. The statute is the boundary, not the list. If the ship operated inside 12 nautical miles, the deck logs held at the National Archives prove it, and the absence of a hull number from a VA spreadsheet proves nothing at all.
“"The 2019 law only pays from 2020 forward."”
This is the most expensive sentence in the entire Blue Water file, and it is wrong. Herbicide claims carry the Nehmer effective-date rules at 38 CFR 3.816, which can reach back to the date of the original denied claim rather than the date of the new one. A sailor denied in 2005 and granted today may be owed the years in between. That is the single biggest reason to have the old paperwork found.
“"You never set foot in country, so where is the exposure?"”
The route was the water, not the soil. The ship distilled seawater for drinking, cooking, and washing, and distillation does not remove dioxin the way it removes salt — Australian government work found it could concentrate it. The crew drank the exposure. Congress accepted that reasoning when it wrote § 1116A.
“"My husband was denied years ago and he has since passed away."”
The claim does not die with the veteran. Dependency and Indemnity Compensation and accrued benefits are separate survivor claims, and under Nehmer a retroactive award on a herbicide condition can be paid to the survivor. Widows of Blue Water sailors denied before 2020 are the most under-claimed group in this entire population. Speak to an accredited representative about your own file.

On a Blue Water file the effective date is frequently worth more than the rating. Nehmer can move an award back years, and nobody at the VA volunteers it.
The old denial letter is the most valuable piece of paper in the file. Finding it — in a drawer, in a claims folder, in the C-file — is often the first real work.
When the ship is not on VA’s list, the case becomes a records project at the National Archives. That is an unfamiliar exercise for most claimants and a routine one for a representative.
Survivors of sailors denied before 2020 are the most under-claimed group in this population, and the survivor forms are not the same forms the veteran used.
Prostate cancer and ischemic heart disease residuals are chronically under-rated once the active phase ends. Reading the rating criteria against the actual medical record is where the correction happens.
