Classification

Brown water, blue water — and the line between them.

Brown water is the inland world — the rivers, canals, and harbors of Vietnam, where patrol boats ran and where support ships anchored. Blue water is the open ocean beyond. For decades, the VA paid Agent Orange presumptions to one world and fought the other — until the courts and Congress drew the legal line where it sits today.

Where the line is now

In Procopio v. Wilkie (January 29, 2019), the Federal Circuit held that “served in the Republic of Vietnam” includes service in Vietnam's territorial seas. Congress then wrote the rule into statute: the Blue Water Navy Vietnam Veterans Act of 2019 (Public Law 116-23, signed June 25, 2019; benefits effective January 1, 2020), codified at 38 U.S.C. § 1116A.

The rule today: a veteran who served on a vessel operating within 12 nautical miles seaward of the demarcation line of the Republic of Vietnam, between January 9, 1962 and May 7, 1975, is presumed exposed to herbicides — the same presumption long held by those who served on land and on the inland waterways. Service on land and in the inland waterways was never in question. The PACT Act of 2022 widened the map further, adding presumptive exposure locations in Thailand, Laos, Cambodia, Guam, American Samoa, Johnston Atoll, and stateside installations.

The fight over where that line sits — Haas, the harbor exclusion it upheld, Procopio, and the 2019 Act that buried the exclusion — is worked through as a case at DearDougCollins.com: Blue Water, Brown Water, and the 12-Mile Line.

Nehmer readjudication: claims denied between September 25, 1985 and January 1, 2020 that would have been granted under the new law were ordered readjudicated — with effective dates that can reach back to the original claim. If you or a parent were denied in those years, the denial is not necessarily the end of the story. Start at the evidence page.

The harbor seam

Between the river and the open sea sits the hardest ground in this law: a great harbor. A ship at anchor in Da Nang harbor was not on a river, and it was not on the open ocean either. For a generation, the VA's answer — upheld in Haas v. Peake (2008) — was that an “open deep-water harbor” such as Da Nang was not Vietnam at all for exposure purposes. Procopio killed that reading, and the 2019 Act buried it: a pier at Da Nang sits landward of the Act's offshore line entirely, and the VA's own ships list has always carried a category — Category III — for ships that docked to shore or pier in Vietnam, whose crews are presumption-eligible for the docking period. Harbor cases turn on documents: where the ship sat, what the ship list says about her, and what her deck logs record.

For the ship this hub is founded on, the VA's own list answers the question. It is set out below.

One sailor's record

Printed on the verified line.

This hub was founded on one sailor's service. His classification is stated here exactly as far as the documents carry it — in three parts, kept separate on purpose.

What the record shows

Thomas Alan Bowman Sr., Radioman Second Class, U.S. Navy 1960–1970. His DD-214 records USS ARIKARA (ATF-98), a fleet ocean tug, as his last duty, and an honorable discharge February 10, 1970 — the same month his documented exposure period ends. His final tour was the Da Nang tour.

VA's own Agent Orange ships list names ARIKARA twice: Category II, for salvage operations on the Saigon River in August 1966; and Category III — ships that docked to shore or pier in Vietnam — “docked to piers at Da Nang from September to December 1969,” squarely overlapping his documented window. The Navy's own history (DANFS) gives her the campaigns Vietnam Summer–Fall 1969 and Vietnam Winter–Spring 1970 — the two windows that bracket his tour exactly.

His VA Agent Orange Registry examination (September 12, 2019) records, in the VA's own words: “Exposure Periods: 12/69 to 2/70” — “anchored in Denang harbor. Involved in salvage operations off shore.”

And the VA has already ruled. In August 2019 it mailed him the old harbor exclusion — exposure “will not be presumed if your ship just anchored temporarily in an open deep-water harbor such as Da Nang… and you remained on the ship.” Months later, after the Blue Water Navy Act took effect, the VA granted his diabetes “associated with herbicide exposure” (January 2020) and granted the presumptive cancers at 100%, permanent and total (2022, 2023). Under current law his Da Nang service is presumptive-exposure service. That question is settled — by the VA itself.

One label this page will not use for him: in the VA's technical taxonomy he is not “Category I Brown Water Navy” — that designation belongs to the Mobile Riverine Force and the inland-waterway patrols. ARIKARA was a fleet ocean tug. His own self-description — “brown water vet” — is carried on this site as exactly that: his words for his service, anchored to the ships-list facts above. The accurate line is the stronger one anyway: a fleet salvage tug that tied up to the pier at Da Nang — a ship the VA's own exposure list names twice, while its 2019 letter told the sailor the harbor didn't count.

What the family holds as his account

That he personally went ashore — boots on the ground at Da Nang, where, when, and to do what. The family's story records off-boat excursions during the salvage work. His own Registry-exam answers, it must be said plainly, claim exposure by his service and presence, not by shore excursions — and no service document in hand yet corroborates the ashore specifics. They are printed here as his account, labelled as such, until the documents in the next box land.

What would settle the rest

The exposure and classification questions are settled (previous box). What remains open is only the ashore specifics, and two documents close them: his Official Military Personnel File from the National Personnel Records Center (assignments and any shore-party entries — the family's wanted-list carries this pull as open item W24), and ARIKARA's deck logs for December 1969–February 1970 (National Archives, Record Group 24) — daily positions, pier berths, and any working parties recorded ashore. One deck-log line placing a salvage party ashore converts his account into documented fact, and this page will change the day it arrives.

Stated once, plainly, because families deserve the whole of it: nothing further turns on this classification for him — he already holds everything the classification was ever for, at 100%, permanent and total. And no survivor's claim arises on his record: his wife, Julieanne, died in 2019, before the cancer grants, and Dependency and Indemnity Compensation runs to a surviving spouse, eligible children, or dependent parents. If anyone offers to sell this family a different story, they are selling something that does not exist. The classification's value now is what it has become on this page: a complete, documented, worked example of the fight itself, kept for every sailor whose file is still open.

His concession is one entry in a longer record. The dated history of Agent Orange itself — what was documented while the spraying was still going on, how long the claims were denied, and what finally forced the concession — is kept at DearDougCollins.com: They Knew: Agent Orange.
