AWWA and WaterRF Free Cyanotoxins Guide Now Available

The American Water Works Association (AWWA) and the Water Research Foundation (WaterRF) have released a new guide to help water utility managers detect and control cyanotoxins from harmful algal blooms entitled, “A Water Utility Manager’s Guide to Cyanotoxins.” The guide addresses cyanotoxin occurrence, source water management, and treatment strategies. It is presented in a simple Q&A format, and is available for free download from both the AWWA and WRF web sites. A more technical companion document is also in development to be published this summer, after EPA releases its new health advisory levels and analytical metthods for microcystin and cylindrospermopsin next month.


EPA, NASA, NOAA and USGS Creating Early Warning System to Detect Harmful Algal Blooms

EPA has announced that it’s developing an early warning indicator system using historical and current satellite data to detect algal blooms.  EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies:  NASA, NOAA, and the U.S. Geological Survey.  The multi-agency project will create a reliable, standard method for identifying cyanobacteria blooms in U.S. freshwater lakes and reservoirs using ocean color satellite data.  Several satellite data sets will be evaluated against environmental data collected from these water bodies, which allows for more frequent observations over broader areas than can be achieved by taking traditional water samples.  To read EPA’s news release, visit the web site HERE.

From Texas to Maine, NOAA’s Expanded Flood Information Tool Promotes Resilience

A NOAA flood exposure risk mapping tool that was developed in New York, New Jersey, Delaware and Pennsylvania has now been expanded to cover coastal areas along the entire U.S. East Coast and Gulf of Mexico. The Coastal Flood Exposure Mapper, a deliverable of President Obama’s Climate Action Plan, provides users with maps, data, and information to assess risks and vulnerabilities related to coastal flooding and hazards. According to the 2010 U.S. Census Bureau population count, 39 percent of the U.S. population lives in counties subject to significant coastal flooding.  This mapping tool visualizes anticipated flood effects, thereby aiding preparation for coastal storms.

With this NOAA tool, users select their location and the flood scenario of their choosing: Federal Emergency Management Agency flood designations, shallow coastal flooding associated with high tides, or flooding associated with sea level rise or storm surge. Flood maps are then overlaid with any of three exposure maps to show how floodwaters might impact area assets. All maps can be saved, printed, and shared.

  • The societal exposure map provides information on population density, poverty, the elderly, employees, and projected population growth. Communities can use this information for community planning and to determine how floodwaters might affect vulnerable or concentrated populations.
  • Roads, bridges, water, and sewer systems can be damaged by coastal flooding. Communities can use the mapper to assess infrastructure vulnerabilities and associated environmental and economic issues to determine what steps are needed to protect these assets.
  • The ecosystem exposure map provides data and information about natural areas and open spaces—including their proximity to development — to help communities identify which areas can be conserved for future flood protection benefits. Pollution sources are also identified to show where natural resources could be affected during a flood.

This map tool was developed by the NOAA Office for Coastal Management.

Register Now for the 2nd CWA-SDWA Toolkit Webinar

ASDWA, the Association of Clean Water Administrators (ACWA), and the Ground Water Protection Council (GWPC) are pleased to announce that the Second CWA-SDWA Toolkit Webinar will be held on April 28th from 12:30 p.m. – 2:00 p.m. (eastern).  This webinar is entitled, “Using Water Quality Standards, Monitoring, Assessment, and Impaired Waters Listings to Protect and Preserve Drinking Water Quality.”

It is the second of four webinars in a series to provide more detailed information about the CWA-SDWA Toolkit entitled, “Opportunities to Protect Drinking Water Sources and Advance Watershed Goals through the Clean Water Act:  A Toolkit for State, Interstate, Tribal, and Federal Water Program Managers.”  The toolkit was developed by a workgroup that included many state, EPA Headquarters, and EPA Regional representatives from clean water, drinking water, and ground water programs.  During subsequent webinars, speakers will share information and state examples from Sections 3–5 of the toolkit on Total Maximum Daily Loads, National Pollutant Discharge Elimination System Permits, Nonpoint Source, and Clean Water Act 319 Programs.

State and EPA water managers are encouraged to attend, and registration is open to anyone else who would like to participate.  Please view the attached flyer for the complete agenda and use the following link to register:
