What are the effects of pollution from stormwater runoff?

  • Sediment can cloud the water and make it difficult or impossible for aquatic plants like sea grass to grow.  It can also destroy aquatic habitats.
  • Yard waste (grass clippings and plant trimmings) decays and creates high levels of nutrients that feed algae blooms that can lead to fish kills and formation of muck.
  • Bacteria and other pathogens can wash into swimming and fishing areas, creating health hazards.
  • Debris like plastic bags and bottles, six-pack rings and cigarette butts can choke or suffocate ducks, fish, turtles and birds.
