These daily swings can be quite large when there are algae blooms fueled by nutrient pollution, and can lead to poor aquatic conditions and fish kills. The Conservation Law Foundation opposes the permit given to Mirant for the Veolia Energy North America Kendall Cogeneration Station, an electricity plant near Kendall Square, charging that the water it releases causes blooms of hazardous microorganisms because of its warm temperature.
