Join solutions-oriented researchers, remediation technology and equipment companies as they tackle the reduction and remediation of worsening harmful algae blooms and red tide events taking place in the US and globally. Due to different types of blooms in canals, streams, rivers, lakes, marina's and coastlines NAA facilitates  Algae Bloom & HAB Remediation Workshops/Webinars to find holistic, end-to-end, eco-friendly, decentralized remediation solutions proven outside the lab, scalable that are economically feasible that can be deployed today on waterways by states, counties, lake associations and other water quality authorities.

Harmful Algal Blooms

Harmful algae blooms in waterways are affecting fishing, swimming, tourism, real estate values and local economies and have been determined to be health risk to humans and animals.  

Decades of research, testing and monitoring harmful algae blooms have not fixed these devastating water quality problems. They worsen every year. 

The goals of our On-Farm Nutrient Remediation, Recycling and Repurposing Pilot Test Program
are to help remediate and reduce nutrient run-off at at non-point sources before entering waterways. The National Algae Association, in collaboration with farmer nutrient stewardship professionals, is facilitating pilot tests bringing together algae remediation and algae production technologies with nutrient stewardship farmers to help remove and reduce N & P effluent and liquid manure at farm drainage systems and use the effluent to grow algae for biofertilizer that can be recycled to the farm as well as other potential products. 

States, counties, algae task forces, lake associations, watershed and coastal authorities are interested in solutions proven outside the lab, scalable and economically feasible for many different types of waterways. If your technologies qualify or if you wish to participate as a stakeholder, please let us know.
"A harmful algal bloom (HAB) contains organisms that can severely lower oxygen levels in natural waters, killing marine life. Some HABs are associated with algae-produced toxins. Blooms can last from a few days to many months. After the bloom dies, the microbes which decompose the dead algae use up even more of the oxygen, which can create fish die-offs. When these zones of depleted oxygen cover a large area for an extended period of time, they are referred to as dead zones, where neither fish nor plants are able to survive.  

HABs are induced by an overabundance of nutrients in the water. The two most common nutrients are fixed nitrogen (nitrates, ammonia, urea) and phosphate. These nutrients are emitted by agriculture, other industries, excessive fertilizer use in urban/suburban areas and associated urban runoff. Higher water temperature and low circulation are contributing factors. HABs can cause significant harm to animals, the environment and economies. They have been increasing in size and frequency worldwide, a fact that many experts attribute to global climate change".  Wikipedia
