This bill aims to better fight harmful algal blooms and low-oxygen “dead zones” in oceans, coasts, rivers, lakes, and reservoirs. It continues federal work on this problem through 2030 and strengthens how agencies plan, monitor, and respond. Harmful algal blooms can make water unsafe, kill fish, hurt local economies, and threaten health. The bill requires a national plan every five years, adds the Department of Energy to the federal task force, and expands NOAA’s and EPA’s roles to track, predict, prevent, and reduce these events .
