A recent study from Penn State University has shed light on potential environmental risks facing bald eagles in Pennsylvania, connecting them to contaminants found in freshwater mussels near a former oil and gas wastewater treatment facility. The research highlights how the oversight of wastewater discharges, such as radium, can have serious implications for the local food chain.
The study, conducted near Franklin, Pennsylvania, found elevated levels of radium—a radioactive element—in the soft tissue, shells, and sediments of freshwater mussels. This pollution is particularly concerning considering that bald eagles, which feed on muskrats that consume these mussels, could be affected by bioaccumulation of contaminants up the food chain. The mussels are not just a food source; they also play a crucial role in maintaining the health of freshwater ecosystems through their filtration capabilities.
Evan Clark, a waterkeeper at Three Rivers Waterkeeper, likened the situation to the historical warnings of Rachel Carson in her landmark book “Silent Spring,” where harmful pesticides affected wildlife populations. Similarly, the ongoing contamination of ecosystems can have far-reaching consequences for apex predators like bald eagles.
While wastewater from fracking has been banned from being released into waterways, the damage caused by previous discharges remains a concern, as contamination lingers in the environment. The study indicates that mussels living within half a kilometer of pollution discharge points showed higher concentrations of radioactivity. This raises important questions about the broader implications for other wildlife species, including muskrats and otters, as well as potential long-term impacts on human health.
Despite these challenges, it is heartening to note that initiatives are in place aimed at restoring and preserving wildlife populations and ecosystems in Pennsylvania. The state has seen the return of otters and the reintroduction of bald eagles since the 1980s. The research underscores the importance of continued vigilance in protecting these recovering species and highlights the resilience of natural systems despite facing industrial pressures.
Efforts to monitor and mitigate further contamination are crucial in ensuring the health of not just local wildlife, but also the communities that depend on clean water and healthy ecosystems. Although there is a long way to go, awareness and scientific inquiry are key to understanding and improving environmental conditions moving forward.
