The Philippine Coast Guard (PCG) reported an oil spill in Mariveles, Bataan, on November 7, 2026, affecting approximately 500 square meters of coastal waters. According to the Philippine Statistics Authority (PSA), oil spills caused P4.93 billion in damages in 2023, representing 53% of total human-induced disaster damages that year. The US National Oceanic and Atmospheric Administration (NOAA) defines crude oil as a fossil fuel used in various petroleum products, from gasoline to plastics and paints. Oil spills can occur on small scales, such as during ship refueling, or large-scale incidents like pipeline ruptures or tanker sinkings. A notable example in the Philippines was the 2024 MT Terranova incident, where a ship carrying 1.4 million liters of industrial fuel oil sank off Bataan, leading to the recovery of over 1 million liters of oily waste during cleanup. The Department of Health (DOH) has highlighted health risks from oil spills, including nausea, skin irritation, and respiratory issues from inhalation; skin burns and dermatitis from contact; and vomiting, diarrhea, and potential unconsciousness from ingestion. The DOH advises posting warning signs, avoiding drinking water from affected areas, keeping children away, and seeking medical attention for symptoms. The PCG and DOH are working together to address the immediate health and environmental impacts of the spill, emphasizing community safety and environmental protection. This incident underscores the ongoing challenges of managing oil spills and their far-reaching effects on marine ecosystems and coastal communities in the Philippines.

The Philippine Coast Guard has deployed spill booms and absorbent materials to address an oil spill incident in the waters off Mariveles, Bataan. According to the agency, approximately 25 liters of used oil were spilled into the sea on Thursday, affecting 500 square meters of coastal waters in Barangay Ipag. Initial investigations indicate the oil originated from washing activities, though the exact source remains unidentified. The Coast Guard has utilized seven absorbent booms and 2,200 absorbent pads for the cleanup operation, with additional support from the provincial disaster risk reduction and management office. Over 800 kilos of oil-contaminated debris have been collected and placed in 40 sacks for proper storage pending further investigation. The Department of Environment and Natural Resources has directed officials from DENR-Central Luzon and environmental management groups to assist in the cleanup efforts. The Coast Guard resumed cleanup operations yesterday, but the full extent of environmental damage to coastal communities has yet to be assessed. Authorities continue to investigate the source of the spill to prevent future incidents and protect marine ecosystems in the area.

After 16 years, this disaster is still ongoing.

A new study published in the Proceedings of the National Academy of Sciences reveals that the 2010 Deepwater Horizon oil spill caused a severe and long-lasting decline in deep-sea marine life in the Gulf of Mexico. Researchers found that animal populations, including octopus, krill, squid, and shrimp, declined by 60 to 85 percent within three and a half years of the spill, with no significant recovery observed over the subsequent decade. The study, which analyzed data from nine surveys conducted between 2011 and 2023, identified the spill as the 'fastest and most severe faunal decline' ever documented in Earth's largest ecosystem type. Krill and lanternfish, foundational species in the Gulf's food web, were particularly affected, leading to genetic bottlenecks that could further hinder ecosystem recovery. The research also suggests that lingering pollutants may interfere with species' ability to find mates by disrupting their sense of smell. Scientists ruled out other factors such as water temperature and oxygen levels, concluding that the oil spill was the most plausible explanation for the ecosystem collapse. The study's comprehensive approach, combining net hauls, acoustic surveys, and genetic sampling, provides strong evidence supporting this conclusion. Despite a $20.8 billion settlement by BP in 2016 for environmental restoration, the Gulf's deep-sea ecosystems remain significantly impacted, with some species showing an 80 percent decline in population. Lead author Tracey Sutton noted that large predators like sperm whales, once common near the Mississippi River, have not been seen for over a decade. The findings highlight the long-term environmental consequences of industrial disasters and raise concerns about potential impacts from future deep-sea mining activities.

In 2010, the Deepwater Horizon oil rig failed catastrophically, leading to the largest oil spill in the history of Earth's oceans.
