June 22 AWRA Webinar on Online Source Water Quality Monitoring for Drinking Water Applications

awra june 22 webinar

This Thursday, the American Water Resources Association (AWRA) is hosting a free webinar about EPA’s guidance document entitled, “Online Source Water Quality Monitoring For Water Quality Surveillance and Response Systems.”  During the webinar, Steve Allgeier of EPA will discuss the systematic process for designing an effective online source water monitoring system to help detect water quality incidents (e.g. spills and harmful algal blooms), optimize treatment processes, and characterize long-term trends.

Date:  Thursday, June 22, 2017
Time:  1:00pm (eastern)

Webinar participants will learn best practices on how to:

  • Identify source water threats and assess risks
  • Select water quality parameters and monitoring locations
  • Design water quality monitoring stations
  • Design information management systems to support data analysis
  • Develop procedures to respond to unusual source water quality conditions

Seating is limited – Register here!

EPA Water Quality Modeling Webinar

download

On Wednesday July 12th from 1:00pm – 3:00pm (eastern), EPA’s Water Modeling Workgroup will host a webinar titled “Introduction to WASP,” as part of its webinar series to help water quality professionals better understand surface water quality modeling and how models can be used to solve common problems that face water quality regulators. These webinars are focused on modeling as it applies to the Total Maximum Daily Load (TMDL), Standards, and Water Quality Permitting Programs, but they are applicable to a wide range of audiences, including state source water protection program staff.  This webinar will introduce the Water Quality Analysis Simulation Program (WASP) water quality model. WASP enables users to interpret and predict water quality responses to natural phenomena and manmade pollution for various pollution management decisions. The webinar will also highlight how this tool is being used by several states and others for their TMDL, nonpoint source, and municipal stormwater programs.

EPA Webinar on Global Change Explorer Web Tools

On Wednesday, May 31 from 2:00pm – 3:00pm (eastern), EPA’s Safe and Sustainable Water Resources research program will host a webinar about its Global Change Explorer collection of web tools that allow visualization, comparison, and access to spatial data that describe potential future environmental change. These data can serve as a starting point to assess the vulnerability of air, water, ecosystems, and human health to climate change, land use change, and other large-scale environmental stressors. The data and tools are relevant across multiple scientific disciplines and environmental media, providing a foundation for integrated assessment of global change.

During the webinar, presenters from EPA’s Office of Research and Development will provide an overview of the three web tools – Land Use, Watersheds, and Deposition — that comprise the Global Change Explorer.  REGISTER HERE

USGS Publishes National Brackish Groundwater Assessment

Brackish Groundwater in the United States

USGS has published a new study that suggests brackish groundwater could help stretch limited freshwater supplies. This study found that the amount of brackish groundwater underlying the country is more than 800 times the amount currently used each year. With issues like drought, groundwater depletion, dwindling freshwater supplies, and demand for groundwater expected to continue to rise, understanding brackish groundwater supplies can help determine whether they can supplement or replace taxed freshwater sources in water-stressed areas. Although this assessment can’t answer all of the questions related to sustainable use, it represents a starting point for identifying the gaps in our knowledge and for directing research to locations where further study would be most beneficial.

New USGS Interactive Map Looks at Long-term Water Quality Changes

USGS Mapper

USGS has launched a new interactive map that provides a comprehensive, long-term look at changes in the quality of our Nation’s rivers and streams over the last four decades. For the first time, monitoring data collected by 74 organizations at almost 1,400 sites have been combined to provide a nationwide look at changes in the quality of our rivers and streams in the 40 years since passage of the Clean Water Act.  The interactive map can be used to track trends of 51 water-quality constituents and 38 aquatic-life metrics at nearly 1,400 sites during four time periods between 1972 and 2012.  For more information about this and other maps, visit the USGS website.

EPA Releases New Updated Version of DWMAPS

dwmaps

EPA has released a new 2.0 Version of its Drinking Water Mapping Application to Protect Source Waters (DWMAPS) tool.  DWMAPS 2.0 now provides real-time updates from data sources and improves interactivity within EPA’s GeoPlatform and with users’ own data. DWMAPS is an online mapping tool that helps state and utility drinking water professionals in concert with other state and local mapping tools to update their source water assessments and protection plans. Watershed protection groups and source water collaboratives can also use DWMAPS to locate drinking water providers, potential sources of contamination, polluted waterways as well as information on protection projects and Source Water Collaboratives in their area.

Certain features have been modified from the original version. For example, in DWMAPS 2.0 the “Potential Sources of Contamination” tool currently searches only for dischargers permitted through the National Pollution Discharge Elimination System (NPDES) program. Users may explore additional point sources regulated by other programs in the DWMAPS 2.0 layer list.   DWMAPS can be accessed directly at: https://www.epa.gov//dwmaps.  For more information or questions, please contact Sherri Comeford of EPA at Comerford.Sherri@epa.gov or (202) 564-4639.
