Degraded Condition of Georgica Pond
Georgica Pond is eutrophic, with excessive nitrogen inputs from ground and surface water runoff feeding dense plant life, the decomposition of which is blamed for choking the pond of oxygen, the condition known as hypoxia. To combat that decomposition, the Friends of Georgica Pond Foundation has operated an aquatic weed harvester in recent summers to remove macroalgae before its decomposition can promote blooms of cyanobacteria, the blue-green algae that have beset the pond annually.

In an ongoing effort to remediate the degraded condition of Georgica Pond, which has experienced toxic algal blooms every summer since 2012, a group of pondfront property owners sought and received permission from the East Hampton Town Trustees to take part in a sediment chronology study. The lake coring sample will offer an opportunity to explore and reconstruct the history of eutrophication [harmful algal blooms] and other algae in Georgica Pond and may, in turn, provide insight regarding the history of the watershed.

Harmful Blue-Green Algae Blooms - Cyanobacteria are commonly referred to as blue-green algae. They occur naturally in waters used for recreation, fishing, and drinking water. When blooms are formed by toxin-producing bacteria, it is generally referred as a Harmful Algal Bloom.
