This bill directs the National Oceanic and Atmospheric Administration to study the effects of hazardous waste dumping in the San Pedro Basin off the California coast, with a focus on DDT and other industrial contaminants including military explosives and radioactive materials that were historically dumped there. The administrator must conduct monitoring and research to understand how these contaminants spread through the marine environment and food web, develop new technologies for studying ocean contamination, and explore whether bioremediation techniques could help clean up the dumped waste. The bill also authorizes grants for research on seafloor contamination and requires the administrator to submit a comprehensive report to multiple congressional committees within three years, identifying other offshore dump sites and recommending a strategy for further research and cleanup efforts. The legislation provides six million dollars per year in funding from fiscal year 2028 through 2034 to support these research and remediation activities. The bill affects ocean health, marine ecosystems, and potentially human food security through seafood consumption in the affected region.
