Nutrient pollution from farm and lawn fertilizer, pet and livestock waste, runoff from roads and houses, faulty septic systems, and treated sewage, can turn waters green with algae and pollute waters for swimming, boating, and fishing. You can prevent this from happening to your favorite water body by taking care not to over fertilize your lawn; picking up pet waste and properly managing waste from livestock; using green practices such as rain barrels, rain gardens and permeable pavements; maintaining your septic system; and encouraging your community to invest in its wastewater infrastructure.
This video is intended to illustrate what can happen during a Harmful Algal Bloom (HAB). Cyanobacteria blooms can have a similar appearance and are often associated with layers of green slime and clumps of algae floating on the surface of the water. This reenactment was designed to help raise awareness about the problem of nutrient pollution and its potential impacts on human health and the aquatic environment. However, no humans were put at risk during production, and there were no real warnings or restrictions posted at this particular waterbody.
