EPA Tools and Resources Webinar Series

Free webinars typically held the third Wednesday of every month from 3:00-4:00 PM (ET). 

EPA's Office of Research and Development (ORD) hosts this monthly public webinar series to translate EPA research and share research resources and information that are useful, practical/applied and available to meet research needs of states/territories and other entities, such as tribes, local governments, and communities. In addition, the EPA Tools and Resources Training Webinar Series provides in-depth overviews and step-by-step tutorials on popular EPA science-based models and tools. 

NOTE: Attendees have the option of receiving a certificate of attendance. Acceptance of certificates is contingent on organization requirements—EPA cannot guarantee acceptance. Closed-captioned recordings of the webinars are provided below for later viewing and as a training resource; certificates cannot be provided for viewing webinar recordings. Webinar dates and topics are subject to change.

Freshwater Explorer

Register for the Freshwater Explorer webinar!

The Freshwater Explorer is an interactive mapping tool for visualizing water quality. States, Tribes, and other groups contribute water quality information to a database through the Water Quality Exchange (WQX). To make it easier to visualize these data, EPA scientists developed this interactive web-based mapping tool. 

In its first public release, Freshwater Explorer provides information about background and observed conductivity, a measure of salt content, for freshwater streams, lakes, and wells in all 50 U.S. states, Puerto Rico, and the U.S. Virgin Islands.  Salts can harm aquatic life and can be indicative of the presence of other pollutants. Data for nutrients will be added in 2022. 

Freshwater Explorer is useful to assess water quality and share watershed and regional stories.  It enables WQX contributors to spot data integrity issues and improve data quality hosted on the WQX. In this webinar, the functionality of the Freshwater Explorer is demonstrated using national and localized examples for condition, causal, predictive, and outcome assessment. For example, users can modify what is shown on a customizable map and pull in data from other EPA sources.
