AERATION & WATER QUALITY
Water quality restoration is one of the most frequent and important challenges that we face as lake and pond managers, and should be a high priority for every water body. Poor water quality due to nutrient loading is a constant issue, as runoff containing fertilizers and other pollutants from agricultural farm fields, suburban lawns and gardens, and urban streets and parking lots drains into lakes, ponds, and storm water management facilities. Even natural areas can contribute to water quality degradation through the deposition of sediment, leaf debris and other organic matter to our waterways. These pollutants are the ultimate source of nuisance lake and pond weeds, harmful cyanobacteria (blue-green algae) blooms and other complications that impair water bodies for municipal and recreational uses, and may also make them less habitable for fish and other wildlife.
As a golf course superintendent or property manager, you may have already implemented numerous aquatic management tools such as aeration and nano bubble technology, biological augmentation, nutrient remediation, and innovative sediment and vegetation removal techniques such as bio engineered shorelines and hydro-raking. Another new technology for the sustainable removal of nutrients and other pollutants is generating excitement within our industry. Similar to activated charcoal, this new technology has highly adsorbent properties that allow it to remove impurities from water. These charcoal-like particles can be placed in large, porous bags in moving water, and the particles will attract and trap nutrients, metals and other pollutants. The bags are then removed from the water when they are full, resulting in the physical elimination of the trapped material from the water body. The contacts of the bag can be discarded, or better yet, used strategically as a soil amendment for natural fertilization and as a substrate for beneficial microbes to enhance plant growth.
