To date, IWS basin activities are underway in the Delaware River Basin and in the Upper Colorado River Basin. Starting in 2021, the relationship between nutrients, associated HABs, and water availability in the Illinois River Basin will be studied. Over the course of 2021, USGS will begin broad internal and external stakeholder engagement to help develop a science and monitoring plan for the Illinois River Basin that will guide USGS IWS activities in the basin over the coming years. EPA Updates: EPA's Research, Resources, and Tools on HABs EPA Sanitary Survey App An updated version of EPA's Sanitary Survey App for Fresh and Marine Waters is available and can be used to identify sources of fecal pollution in recreational waters. At this time, the app is only available for use by states, territories and tribes. The App now includes the ability to gather more detailed Harmful Algal Bloom information. The update also includes the ability to monitor fresh waters in addition to marine waters. Additionally, updates were also made to improve usability. For example, the app does not require the use of the Internet or WiFi while the user is out in the field, and survey data can be stored on EPA's GeoPlatform at no cost. To improve data collection, the updated app has the following new functions: • Storing photos • Geolocating sites where data is collected • Linking to websites, such as the National Weather Service, for weather related information (e.g., rainfall, air temperature) Click here for more information or email EPA at EPA SanitarvSurveyApp@epa.gov ------- Recently Published Articles* Oral Microcystin-LR Does Not Cause Hepatotoxicity in Pigs: Is the Risk of Microcystin-LR Overestimated?
