Río Seco Oil Spill, Falcón: Health Risks of the Fumes
Crude oil reached the beach at Río Seco, in Miranda municipality, Falcón state (northwestern Venezuela), between Sunday, November 8 and Monday, November 9, 2026, and the strong hydrocarbon smell forced a high school, the Liceo Nacional Esteban González, to suspend classes. According to Crónica Uno, some teenagers had dizziness and nausea, and people with asthma and allergies are affected. Fishermen estimate that between 4,000 and 6,000 people are affected by spills in the area. None of the three reports reviewed includes a response from PDVSA, the state oil company. Data as of November 10, 2026.
What is known
- When and where: the spill began on Sunday the 8th and was reported on Monday the 9th, on the beach and at the fishing port of Río Seco (La Patilla, Notifalcón). Crónica Uno adds that the crude reached the mangroves of Maragüey island.
- Who reported it: fishermen and residents of Río Seco, who filmed the oil on the shore and near the pier.
- Health, per Crónica Uno: the school’s principal, Hildemaro Swanberg, suspended classes indefinitely. The Río Seco outpatient clinic is working with staff wearing double masks because of the smell. Two patients under observation for pneumonia were sent to the hospital in Coro because the clinic has no oxygen; the report does not link them to the spill.
- What residents demand: that PDVSA deal with the problem. Notifalcón reports that fishermen threaten to block the Falcón–Zulia highway if there is no response.
Which pipeline is it?
The three reports disagree, and none confirms the cause:
| Source | What it says about the pipeline |
|---|---|
| Notifalcón | A rupture is “believed” to have occurred in the underwater pipes crossing the Golfete de Coro from Zulia toward the Paraguaná refinery complex |
| La Patilla | A rupture of “an oil pipeline in the area,” with no name or operator |
| Crónica Uno | The Ulé–Amuay pipeline (Line ULE II), 267 km, from the Ulé station in Zulia to Paraguaná. Andrés Osorio, president of the ecology institute Ivacea, says it operates in a state of severe obsolescence under heavy pumping pressure |
What residents say: a pipeline broken for a long time
Neighbors say the strong smells and the contamination come from a pipeline that has been broken for a long time, next to the area where fishing boats anchor, and that they are making children and adults feel ill. That is their account; no medical report has been published to confirm it.
What Crónica Uno does document fits a long leak rather than a one-day event:
- August 30, 2026: fishermen saw another leak coming directly from the body of the pipeline on land.
- September 21, 2026: images from the Copernicus Sentinel-1 satellite confirmed a slick. The analysis covered 379.93 km² and estimated 666.74 m³, about 4,200 barrels (our conversion), consistent with 22 days of continuous leaking.
- November 9: the oil reached the beach. Crónica Uno describes it as the second spill in 60 days.
What are the health risks of an oil spill on the coast?
The smell is not the damage, but it is not harmless either. The U.S. EPA explains, on a page about the 2010 BP spill, that a “gas station” smell comes from volatile organic compounds (benzene, toluene, ethylbenzene and xylene), and a “rotten egg” smell from hydrogen sulfide. No air measurements have been published for Río Seco, so we do not know which one people are smelling.
| Type of exposure | What the sources say |
|---|---|
| Inhalation, short term | Temporary irritation of the eyes, nose and throat, nausea or headache (EPA). ATSDR adds that one petroleum compound can cause headaches and dizziness at high levels in the air |
| People with asthma | May be more sensitive to these compounds (EPA). NIEHS titled a 2022 news release “Oil Spill Cleanup Workers More Likely to Have Asthma Symptoms” |
| Long-term exposure | In animals, effects on the lungs, central nervous system, liver and kidney (ATSDR). Benzene, with prolonged exposure, affects bone marrow and is a known human carcinogen (ATSDR) |
How to read it: the EPA and CDC judged that the levels measured during the BP spill would not cause long-term harm and that symptoms should fade when levels drop or the person moves away. But that was with measurements in hand. At Río Seco none have been published, and residents describe repeated spills, which is exactly what toxicology fact sheets separate from short exposure. The symptoms reported (dizziness, nausea, trouble for people with asthma) match what these sources describe for inhaling crude oil vapors; whether they result from this spill is what has to be measured and diagnosed.
What people can do in the meantime
The EPA advises people who are sensitive to these compounds to stay indoors, keep windows and doors closed and set air conditioning to recirculate, and warns that the smell can get stronger if the wind or weather changes. If symptoms do not ease after moving away from the smell, they do not fit the pattern the EPA describes, and a doctor should see them. This page is information, not medical advice.
A long record in the Golfete de Coro
| Date | What happened | Source |
|---|---|---|
| September 2020 | Fishermen at Río Seco (Arajó sector) report crude from an allegedly broken underwater pipeline; two slicks of 10 to 14 km off the coast | Observatorio de Ecología Política |
| 2020–2024 | At least 64 spills and dozens of gas leaks, per residents’ own records | Crónica Uno (2026) |
| August 2024 | Fissure in lines Pl2 and Pl3 of the Puerto Miranda–Cardón pipeline corridor, at Mitare. PDVSA closed the Tarana valve; fishermen count more than 45 spills in the gulf | El Nacional / Crónica Uno |
| January 2025 | Leak in the LOL-3 pipeline (243 km, the last 23 underwater) at Punta Caimán; about 40 km of coast affected per images from January 21. Mitare has about 1,200 families, 90% living off fishing | Crónica Uno |
| August 30 and September 21, 2026 | Leak seen by fishermen, then a slick confirmed by satellite (see above) | Crónica Uno |
| November 8–9, 2026 | Oil on the Río Seco beach, classes suspended | Notifalcón, Crónica Uno, La Patilla |
What is not known
- How much crude spilled in November or how large the current slick is.
- The exact cause and pipeline: there are three versions (above) and no technical or official confirmation.
- Whether PDVSA has shut off, isolated or repaired the section, or whether cleanup is under way: none of the reports says.
- What is in the air and the water. No measurements of benzene, volatile compounds or hydrogen sulfide have been published, nor any analysis of the fish.
- Who is ill, and with what. The symptoms are accounts from the community and the school; there is no medical report. The 4,000–6,000 affected people are a fishermen’s count, not independently verified.
- Whether classes have resumed.
- The urgent investigation residents are asking for. Neighbors in the area are demanding an urgent investigation and action by PDVSA; residents passed this request to us and it is not yet in a published source.
Why it matters
A 267-km pipeline carrying crude from Zulia to Paraguaná crosses an inhabited coast and a gulf where thousands of fishing families live. When it fails, the damage reaches the people next to it first, and then the barrels that never arrive at the refinery. Paraguaná (Amuay and Cardón) was already processing only 31% of its capacity in April 2026, according to Reuters, as our guide to Venezuela’s refineries (in Spanish) explains.
