Residents in Pasadena in Anne Arundel County tell WJZ they are concerned after learning Maryland Port Administration is considering putting dredge material in part of the river where they swim, fish and boat.
What is dredging?
Dredge is what the administration digs up from the river floor when they clear shipping channels, and due to pollution from nearby industries, that material can be toxic.
“Tar balls and Slag”
Residents say they fear MPA’s plans to store dredge underwater, instead of on land, could harm their waterways and way of life.
“I recall the pollution that came over from Bethlehem Steel,” said Carl Treff, who grew up in Pasadena along the Patapsco River. “Things like tar balls and slag, and who knows what else, would wash up on the shore. I’ve seen what Bethlehem Steel used to dump in this river.”
Treff is part of a group of residents in Pasadena’s waterfront communities trying to stop the Maryland Port Administration’s confined aquatic disposal, or CAD, project.
Ruth Sliviak, another resident, said she was horrified when she heard about the project.
“We waterski, we have our kids out here, grandkids, kayaking, fishing, crabbing,” Sliviak said.
What’s the harm?
MPA maintains vital shipping channels through regular dredging.
However, due to pollution from nearby industries, that dredge material can include contaminated sediment, heavy metals, PCBs and chromium.
That’s why it’s usually stored in containment facilities on land like the one at Cox Creek.
However, CAD involves digging a hole in the river floor and filling it with dredge material.
According to MPA’s website, the proposed location for that hole, or cell, is less than a mile from these waterfront communities.
“We’re very concerned about that being dumped into the water, right near our homes,” said John Garofolo, who lives in Stoney Creek near the proposed site.
Effort to stop dredging
Garofolo has been trying to stop the project since he found out about it last year.
“If you disturb that sediment layer, now you can release a lot of toxic material, the heavy metals, the PCBs, the oils, into the water, and now it’s free to move wherever the current and tide takes it which could be up all of our waterways,” Garofolo said.
Cost-effective solution
According to MPA, finding new places to store dredge is a challenge and CAD offers a cost-effective solution because MPA can use the “good sand” excavated when they dig the hole or cell for other projects.
MPA also said the thick clay under the cell creates a barrier that prevents toxic sediment from escaping.
“We may create a monster”
Residents say they want to see the science themselves.
“They just need to show us consistent and good science, that the bottom of this river is safe to dredge up and safe to start digging 20-acre holes,” Treff said.
“We think that the bay and the river have been working hard to heal itself, and if it was left alone, it would continue to do that,” Garofolo said. “But if we keep stirring up the poisons of the past on the river floor, we may create a monster that we didn’t need to.”
MPA responds
WJZ reached out to MPA for more details on the safety of CAD and in a statement they shared:
“Confined Aquatic Disposal or CAD is a dredged material management concept that is currently being evaluated through the State of Maryland’s Dredged Material Management Program.”
“Due to concerns that were raised following a public information meeting in June 2023, work on a CAD pilot project has been paused.”
“Legislation was proposed in 2024 for a CAD Task Force within the DMMP through the Bay Enhancement Workgroup to further evaluate this concept and ensure public participation in the process.”
“While the legislation did not pass, the Maryland Port Administration is dedicated to continuing with the CAD Task Force and ensuring public participation.”
“The final determination of CAD as a concept and a location for a pilot project will be thoroughly evaluate as part of the CAD Task Force and will be dependent on a variety of variables that will require further assessment, discussion with stakeholders, review by our Dredged Material Management Program committees, and ultimately approval by regulating authorities.”
“Because the CAD pilot project has been paused the dredged material that would specifically be placed into the CAD cell has not been identified but will ultimately be rigorously tested for environmental characteristics to determine suitability for placement and ultimate regulatory approval required by the Maryland Department of the Environment through the permitting process.”
“Dredged material that is classified as hazardous requires special handling and disposal at hazardous waste sites and would not be accepted into a Maryland Port Administration proposed CAD cell. “
