Bill expands federal algae and dead zone research to lakes and rivers

What does this do?

S 93 updates a 1998 law on harmful algal blooms and low-oxygen "dead zones," expanding federal focus from coastal and Great Lakes waters to include freshwater lakes and rivers. It directs NOAA and EPA to research, monitor, and forecast outbreaks, produce a public report every five years, create an incubator program for new detection technologies, and build a database of effective prevention methods.

Who does it affect?

The bill affects NOAA, EPA, and other federal agencies, plus commercial and recreational fishers, tribal nations, farmers, and communities near affected lakes, rivers, or coastlines.

Why does it matter?

Expanding the law's scope and coordination requirements means more waters, communities, and industries—including agriculture—will be factored into federal monitoring and funding decisions on algal blooms.

What does it cost, and who pays?

• $19.5m/year to NOAA through 2030
• $8m/year to EPA through 2030
• $2m/year for major bloom response
