In Nova Scotia, plans to establish North America's inaugural coastal sanctuary for captive whales have entered a crucial stage marked by environmental evaluations, and recent findings have raised some apprehensions. The Whale Sanctuary Project, a U.S.-based initiative, disclosed on Wednesday that it had received results from a pivotal environmental assessment conducted near Port Hilford, N.S. The proposed sanctuary spans 40 hectares and aims to serve as a retirement haven for orcas and belugas retired from marine parks.
Charles Vinick, the executive director of the Whale Sanctuary Project, shared insights on the prolonged two-and-a-half-year investigative journey. The scrutiny was particularly concentrated on the potential repercussions of residual toxic heavy metals, remnants of historical gold mining in the region. The primary concern centered on the possibility of whales ingesting contaminated clams, mussels, and rock crabs containing arsenic and mercury within the submerged soil.
The group acknowledged the presence of gold mine tailings on the sanctuary lands, underscoring the necessity to assess soil and water samples for potential mitigation measures related to heavy metals. The recent findings indicated elevated arsenic levels in the bay's rock crabs, surpassing Nova Scotia's guidelines for human consumption.
Vinick emphasized the need for further investigation into the impact of consuming these crabs on marine mammals, emphasizing the absence of established standards for whales. Collaborating with toxicologists, the group seeks to ascertain whether the arsenic levels pose a risk to the well-being of the retired orcas and belugas.
While mussels in the area were deemed safe for human consumption, the absence of clams in the bay was noted. Vinick reassured that previous studies on the bay had produced positive results, with water analyses revealing no traces of heavy metals or contamination. On land, while mercury levels were within acceptable limits, arsenic was detected around an old stamp mill site. Consequently, any soil disturbed during construction will be covered with an additional layer of soil, gravel, or pavement to mitigate potential risks.
Vinick expressed overall optimism, citing the absence of concerning mercury levels. The ambitious project, announced in February 2020, envisioned the construction of a vast enclosure featuring floating nets, surpassing the size of the most extensive captive whale tanks by 300 times. Initially slated for whale reception in 2022, various challenges, including the COVID-19 pandemic, regulatory hurdles, and environmental considerations, have delayed the timeline. Vinick now anticipates the sanctuary to open sometime in 2024, requiring $20 million in private donations for construction and an additional $2 million annually for operations. The evolving narrative underscores the commitment to ensuring the well-being of marine mammals while navigating the intricate web of environmental considerations and logistical challenges.
