Comprehensive National Mercury Monitoring Act

HR 7275, the Comprehensive National Mercury Monitoring Act, establishes a federal program to track mercury pollution across U.S. ecosystems. The bill directs the Environmental Protection Agency (EPA) to create a national monitoring network at sites in national parks, wildlife refuges, and ecologically sensitive areas, measuring mercury levels in air, water, soil, and wildlife like fish and birds. It requires standardized data collection, a public online database for all collected information, and biennial reports to Congress on mercury trends. The program is authorized to receive $37 million in fiscal year 2025 and $29 million each in 2026-2027, with data intended to inform public health and environmental decisions. This legislation directly affects federal agencies managing environmental monitoring and provides the public with accessible data on mercury contamination.
