New York’s tap water quality is under threat due to invasive species like Hydrilla, Zebra Mussels, and Fishhook Water Fleas. These species can clog water supply systems, change water chemistry, and impact marine ecosystems.
-
Hydrilla: An aquatic plant that spreads across lakes, ponds, and slow-moving rivers in a thick dense mat of vegetation. It blocks sunlight for native aquatic plants, causing them to die off and impacting fish populations.
-
Zebra Mussels: A species that feeds on specific types of algae and discards others, releasing byproducts in their feces that can create a breeding ground for cyanobacteria. This can lead to harmful algal blooms (HABs) that impede fishing and boating, emit unpleasant odors, and reduce oxygen levels in the water.
- Fishhook Water Fleas: A species that eats large quantities of zooplankton, creating better conditions for HABs to grow. They are difficult to eradicate once established and can spread through fishing gear.
Consequences of Invasive Species
-
Clogged Water Supply Systems: Hydrilla and zebra mussels can clog water supply systems, requiring expensive cleaning services to remove them.
-
Water Chemistry Changes: Zebra mussels and fishhook water fleas can influence water chemistry, leading to changes in oxygen levels and pH.
-
Impact on Marine Ecosystems: Invasive species can impact native fish populations, alter food chains, and reduce biodiversity.
Efforts to Combat Invasive Species
The Department of Environmental Protection is working to combat the spread of invasive species through:
-
Monitoring and Sampling: Regular monitoring and sampling of water bodies to detect the presence of invasive species.
-
Education and Outreach: Educating recreational users about the impacts of their actions on aquatic ecosystems.
-
Cleaning Services: Contracting for cleaning services to remove invasive species from water supply systems.
Policy Changes Needed
To effectively combat the spread of invasive species, policy changes are needed, including:
-
Increased Funding: Allocating federal funding to combat the spread of invasive species.
-
Prevention and Early Detection: Implementing policies that prevent the introduction and early detection of invasive species.
-
Public Awareness: Raising public awareness about the impacts of invasive species on aquatic ecosystems.
