Recently, a significant amount of liquid used in power lines was released into the canal in East Rockaway, Long Island. This incident occurred earlier this month when a buried PSE&G transmission cable ruptured, causing distress for local wildlife groups.
On July 14, state officials reported that a synthetic mineral oil, which is used for insulation in high-voltage lines, leaked into the Mill River.
Rescuers noted that the oily substance affected at least four birds, rendering them unable to fly, and resulted in their deaths, as their feathers became coated in the oil.
According to J. Brett Bennington, a professor and chair of geology, environment, and sustainability at Hofstra University, the oil poses a significant threat to small creatures. “It can suffocate them and disrupt gas exchange in gills and other membranes,” he explained.
He further indicated that while the oil floats on the water’s surface, it still has detrimental effects.
Efforts to clean up the spill, which impacted nearby houses, parks, and marinas, are nearing completion, as reported by state officials on Wednesday.
An EPA spokesperson mentioned that the cleanup of the dielectric fluid is close to being finalized.
Experts are awaiting a comprehensive report detailing the actions taken at the site and the proper disposal of materials involved in the cleanup.
To manage the situation effectively, absorbent booms, containment barriers, and vacuum trucks were utilized, with more than 30 workers involved in the effort.
PSE&G stated that they reacted promptly to the leak, ensuring there was no interruption in power service for customers.
The company suspects that the cable’s failure might have resulted from damage to its outer coating over time, although they didn’t provide a detailed explanation.
Despite the adverse impact on local wildlife, PSE&G maintained that the liquid leaked was not hazardous.
Miriam LaFeirovich, a materials science professor at Stony Brook University, emphasized that aging underwater cables are a pressing issue on Long Island. She pointed out that many of these cables lie on the seabed, and their ownership is often unclear when damage occurs.
She cautioned that the mineral oil from such cables can severely disrupt aquatic ecosystems, harming fish, crustaceans, and vital plant species that play a role in capturing carbon dioxide.
PSE&G continues to collaborate with DEC, Coast Guard, local officials, and wildlife rescue organizations to address the ongoing situation, with monitoring set to persist until the site is fully restored.
