Presque Isle Bay is a 3,718-acre natural embayment of Lake Erie located near the northwestern corner of Pennsylvania. The Presque Isle peninsula, a 7.5 mile recurved sand spit that is home to Presque Isle State Park, forms the bay. Most of the shoreline of the bay is fronted by the City of Erie. Over 80% of the bay’s watershed is comprised of urban and industrial land uses in the City of Erie and its outlying townships. The primary tributaries are Mill Creek (including Garrison Run) and Cascade Creek, which together account for about two-thirds of the water flowing into the bay.
As with other parts of the Great Lakes, past waste disposal practices resulted in the discharge of industrial and domestic wastewater to the bay or to the streams and tributaries draining into the bay. Until changes were made to the City of Erie’s wastewater treatment, collection, and conveyance system, untreated industrial, commercial, and residential wastewater escaping from combined sewer overflows was discharged to the bay. Because most of its watershed is a developed, urban area, the bay received high concentrations of pollutants from stormwater runoff. While many pollutants released to the bay from such past practices have decayed through natural biodegradation processes, substances like heavy metals and more resistant organics remain in the sediment.
In January 1991, Presque Isle Bay was designated as the 43rd Great Lakes Area of Concern (AoC) by the U.S. Department of State in response to concerns raised by local citizens. It is the only AoC listed as a result of citizen petition.
Pennsylvania’s Department of Environmental Protection (PADEP) is the lead agency responsible for investigation and remediation of the bay. The Department works closely with partners such as Pennsylvania Sea Grant, Gannon University, the Erie County Department of Health, and other organizations and private citizens through an informal Public Advisory Committee. For more details about the Department’s partners and the Presque Isle Bay Public Advisory Committee, see the Community/Local RAP Group Involvement section below.

Presque Isle Bay Beneficial Use Impairments Of the 14
beneficial uses
|
Through the Remedial Action Plan (RAP) process, PADEP and the Presque Isle Bay Public Advisory Committee identified two beneficial uses as being impaired: Fish Tumors or Other Deformities and Restrictions on Dredging Activities.
Based upon the impaired uses evaluation, the pollutants of concern identified in the sediment were heavy metals and polycyclic aromatic hydrocarbons (PAHs). Fish impairments, if environmentally caused, were believed to be related to the sediment contamination.
Fish Tumors or Other Deformities:
Evaluation began in the 1980s when the United States Fish and
Wildlife Service began receiving reports from anglers of “tumorous”
growths on of the bay’s brown bullhead catfish (Ameiurus nebulosus).
Over the next 22 years, PADEP and its partners conducted numerous
studies of the bay’s brown bullheads. Two studies were done to
estimate and evaluate the overall bullhead population in the bay.
Both studies estimated a population of 31,000 bullheads that was
stable and reproducing. A study of the migration patterns of the
bullheads suggested that the bullheads were primarily resident
species of the bay as only two of the 2000 tagged fish migrated
outside the bay.

Five studies were conducted during which samplings of the bay’s brown bullheads were examined for both internal and external growths and deformities. Subsamples of these fish were autopsied and tissue was examined for the presence tumors. Liver tumor rates fell steadily from a high of 22% in 1992 to 0% in 1999. External tumors rates showed a similar decline from 64% in 1992 to 17.4% in 1999. As a result of the decreasing trend seen in tumor rates, a long-term monitoring strategy was developed and implemented beginning in 2002 with samples collected yearly through 2005. Liver tumor rates in Presque Isle Bay brown bullhead were 3percent in 2002 and 5.9 percent in 2003. Data are not yet available from the 2004 and 2005 monitoring efforts.
In addition, work is underway to develop a reference tumor rate for Lake Erie brown bullheads. The bullhead samples from non-AoC reference sites in New York, Long Point, Ontario, and two locations in Ohio were collected in 2004 and 2005. Evaluation of the liver tissue and the age of the fish will be used to develop a reference tumor rate to compare with Presque Isle Bay results. Bullheads from several lakes in northwestern Pennsylvania were also sampled to determine reference tumor rates for these locations.
Restrictions on Dredging Activities:
As with the brown bullheads, sediment studies have been conducted by
PADEP and its partners since the early 1980s. The studies varied in
scope and focus but did draw similar conclusions. Sediment in the
bay contains widespread but relatively low levels of PAHs and a few
heavy metals (i.e., nickel, lead, and cadmium). Generally, the
concentrations of contaminants found were fairly homogeneous and no
specific hot spots were defined. In addition, sediment dredged from
the navigation channel and turning basin within the bay by the U.S.
Army Corp of Engineers has consistently met the requirements for
open lake disposal in Lake Erie.
A 1997 comprehensive review of data found PAH concentrations in the bay surface sediment were higher than in sediment from most coastal environments but typical of urban areas. Additionally, the review found no clear impacts on the macroinvertebrates in the bay attributed to sediment concentrations of PAHs or other contaminants. To date, there has been no proven correlation shown between bay sediment contamination and fish tumors. These factors coupled with elimination of point source discharges, combined sewer overflows to the bay and its tributaries, and economic impacts resulted in the decision to allow natural recovery rather than pursue active remediation of the sediment.
In 2002, the improvements seen in the health of the brown bullhead and the decision to allow natural remediation of the sediment, led to designation of the beneficial use impairments in the Recovery Stage. As part of the long-term monitoring strategy, a focused sediment sampling effort in 2003 looked at PAH and metal concentrations in historically sampled locations. The concentrations of contaminants in the surficial sediment were consistent with earlier studies.
Delisting Targets
![](images/uparrow.gif)
Work is underway on the development of delisting targets based on both the beneficial use impairments and ecosystem health considerations. With funding from the U.S. EPA - Great Lakes National Program Office (GLNPO), PADEP and PA Sea Grant sponsored a parallel series of workshops with experts on fish pathology and sediment contamination. Via two separate projects following a similar path, delisting targets for the two beneficial use impairments are being developed through the evaluation of historical data, assessment of current study data, consultation with experts on the latest science and its application to Presque Isle Bay, and discussions with the Public Advisory Committee.
RAP Development and Status
![](images/uparrow.gif)
The Stage 1 RAP, completed in 1993, evaluated information from an ecosystem study and identified two beneficial use impairments. The RAP also provided the framework for prioritized ecosystem restoration and management activities to be conducted, coordinated, or sponsored by the PADEP.
The 1995 RAP Update provided revisions and new information to supplement the Stage 1 RAP. It also responded to comments on the RAP received from the International Joint Commission and USEPA.
The 2002 RAP Update recommended that the Presque Isle Bay Area of Concern be designated in the Recovery Stage. This document summarizes the results of studies on the two beneficial use impairments and the work done by numerous organizations in the Bay and its watershed that led to the recommendation for a change in designation.
Current priorities for Presque Isle Bay AoC include addressing
contaminated sediment, understanding and reducing the number of fish
lesion incidences, and developing long-term monitoring plans for the
Bay and its watershed.

Recent Progress and Achievements
Sediment:
In September 2005, PADEP partnered with PA Sea Grant, Gannon
University, the Erie County Department of Health, the Regional
Science Consortium at the Tom Ridge Center at Presque Isle Bay, and
MacDonald Environmental Services, Ltd to implement a comprehensive
sediment-sampling program. More than 50 surficial and at-depth
samples were collected from Presque Isle Bay to characterize both
the current and historical sediment contamination. The USEPA’s
research vessel the Mudpuppy assisted with the collection of
sediment cores. Both chemical and toxicological analyses are being
conducted. The results of the study are expected in 2006.
With funding from GLNPO, PADEP and PA Sea Grant held a series of workshops in 2005 to discuss the sediment contamination in the Bay. Experts from USEPA, United States Geological Survey, National Oceanic and Atmospheric Administration, and several state agencies met with the bay’s Public Advisory Committee Sediment Subcommittee. As a result of the workshops, draft ecosystem health and delisting targets have been developed. Final targets will be proposed by PADEP following the evaluation of the comprehensive sediment sampling results and analysis of data by the experts.
Fish:
In June, July, and August of 2004 and 2005, PADEP continued its
studies on brown bullhead catfish. Samples were collected from
Presque Isle Bay as well as non-AoC Lake Erie reference locations in
New York, Pennsylvania, Ohio, and Ontario. The United States
Geological Survey’s Leetown Laboratory is conducting the analysis of
external body and liver tumors. Results from the 2004 and 2005
studies are expected in 2006.
A series of workshops have been held to address the bay’s Fish Tumors or Other Deformities beneficial use impairment. Under funding from GLNPO, PA Sea Grant and PADEP have conducted these meetings between members of the Public Advisory Committee’s Fish Subcommittee and experts on fish pathology. In addition to assisting with the development of delisting targets for the fish tumor impairment, the experts are developing a manual for pathologists to use in evaluating brown bullhead tumors and providing input into a field manual for biologists.
Several lines of research are underway to better understand the environmental biology and ethology of the Bay’s brown bullhead population. This ongoing research includes:
- A study by Gannon University to sample the deeper, open waters of the Bay. The goal of this research is to better understand seasonal brown bullhead migration patterns and the dynamics of bullhead exposure to contaminated sediment.
- A study of the reproductive success of brown bullhead in Presque Isle Bay by sampling for young-of-year bullhead and tracking recruitment into the population.
- Genetic research to determine the extent to which the Bay’s Ameiurus species hybridize and the potential relationship between bullhead genetics and the elevated tumor incidence rate in this fish population.
PA Sea Grant is funding these studies.
