The site contains approximately 695,000 cubic meters of sediment contaminated with polycyclic aromatic hydrocarbons (PAHs) and other toxic chemicals. This website clearly describes the extent of the problem and the long-term remediation plan that has been underway to restore the harbor. It includes a timeline of milestones showing what has been accomplished so far, an FAQ section, and links to news articles, a podcast, press releases, etc.
