Cyanobacteria blooms have become a growing problem affecting many inland freshwater
lakes. Routes of exposure include ingestion, inhalation, skin contact, and eye contact. Exposure is often related to recreational activities within a water system.
Assume any cyanobacterial bloom as being potentially toxic.
What are Cyanobacteria? š¦
Cyanobacteria, also referred to as blue-green algae, are microscopic plant-like organisms that are naturally
found
within natural streams, rivers, and lakes. The organism thrives in warm, nutrient-rich (high in phosphorous and
nitrogen) environments. Blooms occur when the populations rise rapidly, creating a large floating mass that can
be
bluish-green, brown, red, or yellow in color. Changes in cyanobacteria populations can be an indicator of water
quality
issues.
What are the negative effects of cyanobacteria? š¬
Cyanobacteria blooms can have numerous negative impacts on local freshwater lakes including:
Causing skin irritations or illness including respiratory and gastrointestinal distress.
Toxic to pets, wildlife, and livestock.
Loss of aesthetic appeal and a reduction in property value.
Reduced recreational opportunities.
Reduces oxygen levels within the water column, negatively impacting resident fish, mollusks, invertebrates,
and aquatic
plants.
Preventing cyanobacteria starts at home! š”
Here are some tips for reducing your impact on our waterways and averting
hazardous algal blooms:
Use phosphate-free detergents, personal care, and household cleaning products.
Reduce or avoid the use of fertilizers on lawns. Use phosphorus-free fertilizers only.
Maintain a buffer strip of native vegetation on lake and riverfront properties.
Monitor septic systems to ensure they are not leaching into nearby water sources.
Prevent livestock or pet waste from entering water systems causing excess nutrients and bacteria.
Implement landscaping strategies: aerators or fountains, rain gardens, xeriscaping, or revegetation of
manicured lawns.
