Bio-Augmentation is a fancy word for a simple thing. Essentially, it means adding a certain type of bacteria to an existing lake or pond for the purposes of improving the water quality. Some have actually expanded the term Bio-Augmentation to include Bio-Dredging. Every one can conceptualize what goes on with dredging. Instead of a large crane scooping the muck out, add these bacteria to help decompose the organic material sitting on the bottom of the pond.
In a general sense of Lake and Pond Management, there are two types of bacteria: Aerobic Bacteria (the good guys) and Anaerobic Bacteria (the bad guys). If you are a gardener or a farmer then the roles of the bacteria are switched. Gardeners want the Anaerobic bacteria (now they are the good guys) to help them create the ‘compost’ they add to their garden. Even though this is an over-simplification of the process, the point that is important is to have as much Aerobic Bacteria in the water body as possible. Mother Nature does a very good job of supplying both in a natural setting.
Now factor in an urbanized setting where nutrient overload comes in from a variety of sources. The Aerobic Bacteria is overwhelmed by the Anaerobic Bacteria. Nutrients are processed to a state where they release plenty of food that promotes an algae bloom. By having plenty of Aerobic Bacteria in the water body, they help to consume the nutrients so they no longer contribute to the algal bloom problem.
In summary, Bio-Augmentation (or Bio-Dredging) is the addition of a type of Aerobic Bacteria to help consume the organic nutrient food source that promotes vegetative growth problems in the ponds.
