In this presentation I will discuss the molecular monitoring approaches used in applied environmental microbiology studies conducted in our laboratories. The presentation will primarily focus on the detection and quantification of cyanobacterial groups and cyanotoxin genes implic...

Mountain lakes are important resources for recreation, drinking water, and aquatic habitat but these lakes are particularly vulnerable to changing climate, air pollution, wildfire, harmful algal blooms, and human development. We investigated the condition of and threats to mounta...

Environmental changes impact people&rsquo;s perceptions, values, and uses of waterbodies. Understanding the impacts of environmental changes can help improve governance, practitioner engagement, and user education. We will discuss the green infrastructure (GI) possibilities of cr...

The Cyanobacteria Assessment Network is an interagency project collaboration between US EPA, NASA, NOAA, and USGS. The project aims to advance the science of detecting and monitoring cyanobacteria blooms in lakes across the US using satellite imagery from the MERIS and Sentinel 3...

As part of federal programs to reduce nutrient pollution, states across the Midwest have developed nutrient reduction strategies, which focus on implementation of agricultural conservation practices (ACPs) or best management practices (BMPs). Despite several decades of federal in...

Harmful algal blooms caused by cyanobacteria are a threat to global water resources and human health. Satellite remote sensing has vastly expanded spatial and temporal data on lake cyanobacteria, yet there is still acute need for tools that identify which waterbodies are at-risk ...

General overview of remote sensing, options to consider, and training in preparation for monitoring cyanobacterial harmful algal blooms in the US.

Cyanobacterial harmful algal blooms (cyanoHABs) in reservoirs can be transported to downstream waters via scheduled discharges. Transport dynamics are difficult to capture in traditional cyanoHAB monitoring, which can be spatially disparate and temporally discontinuous. The intro...

Continuous monitoring and assessment of Cyanobacterial Harmful Algal Blooms (CyanoHABs) is a critical need for timely management of water quality and policymaking. This study assessed CyanoHAB magnitude in freshwater lakes across the Contiguous United States (CONUS) using satelli...

A data-driven approach to characterizing the risk of cyanobacteria-based harmful algal blooms (cyanoHABs) was undertaken for the Ohio River. Twenty-five years of river discharge data were used to develop Bayesian regression models that are currently applicable to 20 sites spread-...

The Cyanobacteria Assessment Network (CyAN) project mission is to provide a useful and accessible approach for detecting and quantifying cyanobacterial blooms and related water quality using satellite data records. CyAN developed an early warning indicator system to detect cyanob...

Harmful algal blooms&nbsp;caused by cyanobacteria are a threat to global water resources and human health.&nbsp;Satellite remote sensing&nbsp;has vastly expanded spatial and temporal data on lake cyanobacteria, yet there is still acute need for tools that identify which waterbodi...

CyANWeb is a dynamic web application that provides a user-friendly interface for interacting with CyANO satellite derived daily and weekly datasets. The&nbsp;web app provides all the original functionality found in the CyAN Android app, as well as new enhancements which include t...

The December 1-2, 2021 BOSC review is focused on the SSWR Nutrients and Harmful Algal Blooms (HABs) Topic, one of the three inter-related topics in the SSWR research portfolio. The Nutrients and HABs Topic consists of three Research Areas (RA): RA4 &ndash; Assessment and Manageme...

Algal blooms caused by toxin-producing cyanobacteria are a threat to global water resources and human health. Water resource managers need tools that identify which lakes are at risk of toxic cyanobacteria blooms. We address this need by using Cyanobacteria Assessment Network sat...

The Cyanobacteria Assessment Network (CyAN) is a multi-agency (NASA, USGS, NOAA, and USEPA) project to support the safe public use of U.S. lakes and reservoirs and includes delivery of satellite images of algal blooms via a web-based application developed and hosted by the USEPA....

The Cyanobacteria Assessment Network (CyAN) is a multi-agency (NASA, USGS, NOAA, and EPA) project whose mission supports the environmental management and safe public use of U.S. lakes and reservoirs by providing a capability of detecting and quantifying algal blooms using satelli...

Despite the abundance of various cyanobacteria efforts that are taking place, the problem still exists that there are not good regional perspectives of when, where, and how many blooms are occurring, how long they are lasting, are they producing toxins, is this a newly occurring ...

Harmful algal blooms are increasing in frequency, intensity, and geographic range. Potential impacts from blooms and associated toxins include health risks to human, pets, livestock, wildlife, and other biota; restricted recreational activities; increased treatment costs; and dec...

Drinking water treatment residuals (DWTRs) are a promising media amendment for enhancing phosphorus (P) removal in bioretention systems, but substantial removal of dissolved P by DWTRs has not been demonstrated in field bioretention experiments. We investigated the capacity of a ...

Cyanobacterial harmful algal blooms (CHABs) can produce toxins that impair freshwater ecosystems used for drinking water, recreation, and habitat for aquatic biota. With CHABs increasing in extent and intensity globally, water managers need information about how to prioritize lak...

Algal blooms caused by toxin-producing cyanobacteria are a threat to global water resources and human health. Water resource managers need tools that identify which lakes are at risk of toxic cyanobacteria blooms. We address this need by using Cyanobacteria Assessment Network sat...

We examine how the frequency of cyanobacterial&nbsp;harmful algal blooms&nbsp;(cyanoHABs) generates economic costs through the mechanism of residential property values. We assemble nearly two decades worth of nationwide data on property sales near US inland lakes along as well as...

To assist US EPA Region 1 in addressing questions and concerns related to reissuance of the administratively continued NPDES discharge permit for MWRA’s Deer Island water treatment facility, EPA Region 1 requested that a review team from EPA’s Office of Research and Development e...
