NEWS ON HABs
New Version of bloomWatch App and Bloom Report Dashboard in Spanish Now Available
A new version (Version 4.7) of BloomWatch, an app to engage the public in reporting when and where potential
cyanobacteria blooms appear, was recently released in the App Store for iPhone and the Google Play store for
Android. This new version includes improvements such as a better layout for data submission and email
communication, and a language choice of English or Spanish. More information on BloomWatch is available in the
Cyanobacteria Monitoring Collaborative Website.
Guidelines for Canadian Recreational Water Quality - Cyanobacteria and their Toxins
On February 18, Health Canada released their final guideline technical document on Cyanobacteria and their Toxins
as part of the Guidelines for Canadian Recreational Water Quality. These technical documents provide guideline
values for cyanobacteria and their toxins, and recommend monitoring and risk management strategies. The final
document is posted on Health Canada's Website.
Call for Papers: AWWA Special Issue on Harmful Algal Blooms
The American Water Works Association (AWWA) is requesting papers for a special issue of AWWA Water Science on
the state of the science on HABs and drinking water. In addition to general research topics related to HABs, specific
topics of interest include:
Source water monitoring and control strategies
¦ Treatment technologies and approaches
New analytical methods and sensors for cyanobacteria and cyanotoxins
Disinfection/oxidation byproducts
¦ Taste and odor issues
Regulatory requirements and compliance
Risk assessment
Case studies of freshwater and marine HABs that impact drinking water systems
Effects of climate change relevant to HABs and drinking water systems
Communications and outreach
The deadline for submissions is July 1, 2022.
4th Request for Proposals for the Florida Red Tide Mitigation and Technology
Development Initiative
The Red Tide Mitigation and Technology Development Initiative is a partnership between Mote Marine Laboratory
and the Florida Fish and Wildlife Conservation Commission. It aims to establish a coordinated effort among public
and private research entities to develop prevention, control, and mitigation technologies and approaches that will
decrease the impacts of Florida red tide on the environment, economy, and quality of life in Florida. The Request
for Proposal is open until April 15. More information is available in the Proposal Guidelines document.
USACE's Interagency Freshwater HAB Research & Development Workshop
The U.S. Army Corps of Engineers (USACE) will host a second "Interagency Freshwater HAB Research & Development
Workshop" on March 29-31, 2022. The workshop objective is to share and discuss HABs Research initiatives and
lessons learned between interested federal and state partners, including highlighting emerging efforts and critical
implementation needs.

2021 Harmful Algal Bloom Video Challenge Winners!
2021 HAB Video Challenge Winners!
EPA Region 7 has created a video announcing the winners from the 2021 "See a Bloom, Give It
Room" Video Challenge. The theme for the 2021 competition was urban waters located in the
Kansas City, Missouri, metropolitan area. The competition was supported by EPA's Office of
Research and Development and calls for videos that promote public awareness of HABs through
creative filmmaking. View the video.

Learn to Identify Cyanobacteria Blooms
ITRC-HCB team's Harmful Cyanobacteria Video
The Interstate Technology Regulatory Council's (ITRC) Harmful Cyanobacterial Blooms (HCB)
team, with support from the Lake Champlain Basin Program, developed the Learn to Identify
Cyanobacteria Blooms video which identifies and describes different types of cyanobacteria and
offers guidance on best management and safety practices involving harmful blooms. View ITRC's
guidance, Strategies for Preventing and Managing Harmful Cyanobacteria.
