Little life, toxic heavy metals found in new study of Curtis Bay waters
BALTIMORE, MD., March 16, 2026 – A near complete absence of animal life as well as heavy metals that exceeded Environmental Protection Agency benchmark levels were found in a new pilot study that sampled six sediment sites in Curtis Bay and Curtis Creek near and around the CSX Curtis Bay Piers, the second-largest coal export piers in the United States.
The study was commissioned by environmental justice campaign Coal Kills Baltimore and conducted in a partnership with the Johns Hopkins Baltimore Social-Environmental Collaborative facilitated by the Baltimore Forest School. It was written by Benjamin Zaitchik, the chair of the Morton K. Blaustein Department of Earth and Planetary Sciences at Johns Hopkins University and lead investigator for the Baltimore Social-Environmental Collaborative; Maya Gomes, an associate professor in the department; and Upal Ghosh, professor in the Department of Chemical, Biochemical and Environmental Engineering at the University of Maryland, Baltimore County.
Titled “Coal in Curtis Bay: Impacts on sediment and marine environment,” the study found clear evidence of visible coal and coal-derived debris in the sediment samples as well as excessive levels of toxic metals arsenic, chromium, copper, nickel and lead. The arsenic levels were notably higher near the coal piers than in surrounding areas, although it is not possible to attribute the elevated arsenic directly to the coal as opposed to other industries in the area at this time. Arsenic, chromium and nickel all are classified as carcinogenic.
Polycyclic Aromatic Hydrocarbon (PAH) analysis of two sediment samples to detect and quantify pollutants revealed, in total, the presence of 16 priority pollutants, although not exceeding concentrations above the Marine Sediment Screening Benchmarks of the EPA.
While the study, which has not been through peer review, was not designed to confirm the exact source of the coal, Coal Kills Baltimore calls on the Maryland Department of the Environment to conduct further investigation and analysis to pinpoint its origin and determine whether it is in violation of the Code of Maryland Regulations. The group also urges entities concerned with the health of Baltimore coastal ecosystems to finance independent follow-up studies.
“Coal is not supposed to be found in the waters and sediment of Curtis Bay and Curtis Creek, but we were not surprised,” said John Scheinman, co-founder of Coal Kills Baltimore and a member of Maryland Attorney General Anthony Brown’s Environmental Advisory Council. “We believe its presence violates state regulations. The elevated toxic metals in the sediment are elements naturally present in coal. When there is virtually no life, except a few little worms, it’s not exactly representative of a healthy coastal community. So, who is responsible, and what’s going to be done about it?”
Curtis Bay and neighboring Brooklyn are plagued by poisons discharged daily by the industries on their waterfront, one of the worst polluters being the CSX coal export piers. Dust that blows from CSX’s massive coal piles - in violation of its state operating permit - saturates the air breathed by residents.
Life expectancy in the Curtis Bay area is up to 17 years shorter than in the wealthiest neighborhoods of Baltimore, according to Baltimore City Health Department data.
"We all know about the legacy of past pollution on the Baltimore Harbor, but we know surprisingly little about how specific activities today are affecting the harbor's water, sediment, and ecosystems,” Zaitchik said. “Curtis Bay is a vitally important place to understand those relationships, and to understand them we need measurements like this."
The sediment and marine environment pilot study initiated by Coal Kills Baltimore was designed to complement the report released in December 2023 by South Baltimore community groups working with Johns Hopkins and University of Maryland scientists that definitively showed that CSX coal dust is polluting Curtis Bay and Brooklyn.
“Our sampling was small, and we readily admit this was a one-day snapshot, but there are powerful takeaways from what we found,” Scheinman said. “The scientists tell us the sediment is nearly dead, and coal and metals can change the characteristics of the native sediments and that impacts the benthic community, which is the food source for crabs and fish. If crabs, oysters and other life forms stop living on the bottom, the fish on top don’t survive. Any fish caught in these waters should not be eaten. That may not be news to a lot of people in Curtis Bay, but if nothing is being done about it, we’re trying to issue a wake-up call.
“This is a preliminary investigation into the health of Curtis Bay waters, and the results are not good and should lead people to want to act now. The earlier community-led study found coal dust permeating the air in Curtis Bay. Ours found coal in the sediment. Environmental justice isn’t very fashionable right now, but clean air, water and soil should be baseline human rights, especially in a state that places itself at the forefront of these issues and climate change policy.”
The scientists, along with representatives from Coal Kills Baltimore, gathered their samples for the study on March 26, 2025.
The study was realized through the support of the Johns Hopkins University CHARMED Center (Community Health: Addressing Regional Maryland Environmental Determinants of Disease). CHARMED conducts community-engaged research to better understand links between environmental exposures and adverse health outcomes with the goal of improving the health of vulnerable people in communities across the greater Maryland region.
Maryland regulators in recent years have begun to acknowledge the prevalence of coal dust in Curtis Bay’s air, but a new report suggests the fossil fuel has contaminated nearby waters, too.
