The Pennsylvania Department of Environmental Protection is investigating contamination in Codorus Creek after firefighting water and facility fluids from a blaze at J&K Salvage in Spring Garden Township, York County, were reported by the agency to have flowed into the waterway. A visible oily sheen has been tracked downstream to where the creek meets the Susquehanna River, prompting a joint state and federal cleanup response. The incident raises pressing questions about what chemicals entered the water and whether the creek’s ecosystem faces lasting damage.
Firefighting Runoff Reaches Codorus Creek
When crews battled the fire at J&K Salvage, the water they used mixed with fluids stored at the facility and drained into an unnamed tributary before reaching Codorus Creek. That chain of events, confirmed by the Pennsylvania DEP, turned a local fire into a regional water-quality emergency. Salvage facilities can store a range of petroleum products, hydraulic fluids, and other industrial fluids, meaning the runoff could carry a complex mix of contaminants rather than a single pollutant.
The oily sheen visible on the creek’s surface stretched all the way to the Susquehanna confluence, according to the same DEP announcement issued from Harrisburg. That distance matters because Codorus Creek is a significant Susquehanna tributary, and any pollutants that reach the larger river could spread across a much wider area. For residents along either waterway, the sheen is the most visible sign that something went wrong, but the substances dissolved below the surface may pose a greater long-term risk to aquatic life and sediment quality.
DEP and EPA Deploy Containment Measures
State and federal agencies moved quickly once the scope of the problem became clear. DEP teams, working alongside the U.S. Environmental Protection Agency, have deployed containment booms and vacuum equipment to skim contaminants from the water. Booms are floating barriers designed to corral oil and other surface pollutants so they can be removed mechanically, and they are a standard first response for petroleum-related spills in waterways. The fact that EPA joined the effort signals that the contamination was serious enough to warrant federal resources, not just state oversight.
Still, containment booms and vacuuming address what floats on the surface. They are far less effective against dissolved chemicals or heavy metals that may have settled into creek-bed sediment. Some industrial sites can accumulate metals over time. If sampling shows metals were mobilized into the runoff, standard surface-skimming techniques would miss them entirely. Scientists collecting water and sediment samples will need laboratory analysis to determine whether a second, less visible layer of contamination exists beneath the sheen.
Drinking Water Systems Unaffected So Far
One piece of reassuring news arrived quickly. In its February 26 announcement, the DEP said no public drinking water system intakes had been affected as a result of the J&K Salvage fire runoff. For the communities that draw water from Codorus Creek or the lower Susquehanna, that statement offers immediate relief. The DEP did not detail any additional utility monitoring steps in its announcement.
The absence of drinking-water impact does not, however, settle the broader environmental question. Creek ecosystems depend on water quality at every level, from the microorganisms that break down organic matter to the fish populations that recreational anglers target each spring. An oily sheen can block light penetration and reduce dissolved oxygen, stressing species that are already adjusting to late-winter conditions. If lab results eventually reveal heavy metals or persistent organic pollutants in the sediment, the timeline for ecological recovery could stretch well beyond the visible cleanup.
Gaps in the Public Record
Several critical pieces of information are still missing from the public record. The DEP has not released preliminary lab results identifying the specific chemicals in the oily sheen, and no facility fluid inventory or spill-response plan for J&K Salvage has been made publicly available through regulatory filings. Without that data, scientists and residents alike are left guessing about the severity of the contamination. The DEP statement did not describe any enforcement action, and the nature and scope of any potential legal proceedings, if any, remain unclear.
Equally absent is a baseline for pre-fire water quality in Codorus Creek. Monitoring programs run by state agencies or local watershed groups would normally provide that reference point, allowing scientists to measure how much conditions have changed. Without a clear “before” snapshot, it becomes harder to attribute specific ecological damage directly to the salvage-yard runoff rather than to other pollution sources that may already affect the creek. That evidentiary gap could complicate both the scientific investigation and any future enforcement proceedings.
What Spring Flows Could Mean for Contamination
Timing adds another layer of concern. Late February and early March typically bring snowmelt and increased rainfall across south-central Pennsylvania, raising water levels in tributaries like Codorus Creek. Higher flows can resuspend sediment that settled during the initial contamination event, effectively redistributing pollutants that cleanup crews thought they had contained. If heavy metals or petroleum compounds lodged in the creek bed during the fire runoff, spring flooding could carry them further downstream and into the Susquehanna system.
That seasonal dynamic puts pressure on DEP and EPA to move beyond surface containment and begin sediment sampling before rising water levels scramble the evidence. Most coverage of industrial spills focuses on the first days after an incident, when images of booms and sheen dominate public attention. Yet for contaminants that bind to sediment or bioaccumulate in fish and invertebrates, the real story may unfold over months or years. Long-term monitoring of Codorus Creek and the affected reach of the Susquehanna will be essential to determine whether the firefighting runoff was a short-lived disruption or the start of a more persistent pollution problem.
