Jennifer L Graham, Ph.D.
Jennifer is a Research Hydrologist at the New York Water Science Center
Jennifer Graham currently serves as the harmful algal bloom coordinator for the USGS Water Mission Area. She also represents the USGS on the Interagency Working Group on Harmful Algal Blooms and Hypoxia. Jennifer began her career with the USGS in 1999 as a Volunteer for Science working on harmful algal blooms at the Columbia Environmental Research Center. She worked there as a volunteer until 2005, when she became a Hydrologist at the Kansas Water Science Center. Jennifer joined the New York Water Science Center in 2018. She is a nationally recognized expert in cyanobacteria and associated toxins and taste-and-odor compounds. For over two decades Jennifer has conducted research on the environmental factors influencing the occurrence of cyanotoxins in the United States. She has conducted both regional and single system studies at a variety of spatiotemporal scales.
The overarching theme of Jennifer’s research is the spatiotemporal distribution of algae and algal assemblages with respect to changing physical, chemical, and biological conditions in both lentic and lotic ecosystems. Focus areas currently include anthropogenic influences on algal production and community composition, environmental conditions leading to the development of harmful algal blooms, with an emphasis on cyanobacteria, the occurrence, fate, and transport of cyanobacterial toxins and taste-and-odor compounds, and the development of predictive models for the occurrence of cyanobacterial toxins and taste-and-odor compounds. She has a complimentary interest in evaluating and using leading-edge technology, such as continuous water-quality instrumentation and satellite imagery, to improve predictive capabilities for the onset, duration, and decline of harmful algal bloom events. Research efforts include partnerships within the USGS as well as with local, state, and federal agencies and universities.

Water Cycle Center
The Water Cycle Center is a cooperation between U.S. Geological Survey and academic partners in the Northeast that studies complete water cycles and watersheds, from mountaintops to shorelines, concentrating on freshwater ecosystems. This research advances the understanding of processes that determine water availability and is needed to best address future water resource challenges.
Toxin Producing Algae Across U.S. Landscapes—Are They Gaining a Foothold?
There are still many unknowns related to the occurrence and potential range of various types of algae in inland waters. To fill some of these gaps, scientists at the U.S. Geological Survey (USGS) recently published a review and synthesis of toxic algae in inland waters of the conterminous United States .
Toxins and Harmful Algal Blooms Science Team
The team develops advanced methods to study factors driving algal toxin production, how and where wildlife or humans are exposed to toxins, and ecotoxicology. That information is used to develop decision tools to understand if ​ toxin exposure leads to adverse health effects in order to protect human and wildlife health.
Cyanobacterial Occurrence and Bloom Development in Oligotrophic Adirondack Lakes
Problem Harmful algal blooms (HABs) are increasingly a global concern because HABs pose a threat to human and ecosystem health and cause economic damages. HABs are a concern in waterbodies used for drinking-water supply and recreation in New York State. Toxins produced by some species of cyanobacteria (called cyanotoxins) can cause acute and chronic illnesses in humans. Aquatic ecosystem health a
NWQP Research on Harmful Algal Blooms (HABs)
Harmful algal blooms (HABs) are caused by a complex set of physical, chemical, biological, hydrological, and meteorological conditions. Many unanswered questions remain about occurrence, environmental triggers for toxicity, and the ability to predict the timing, duration, and toxicity of HABs.
Harmful Algal Bloom monitoring in the Finger Lakes region, New York
Background: Harmful algal blooms (HABs) are increasingly a global concern because they pose a threat to human and aquatic ecosystem health and cause economic damages. Cyanobacterial HABs (CyanoHABs) represent a substantial threat to drinking-water supplies, aquatic ecosystem health, and safe recreational uses of freshwater resources in New York.

Effects of Wastewater Discharge and Treatment Facility Upgrades on Environmental and Biological Conditions of Indian Creek, Johnson County, Kansas
The purpose of the study is to assess the effects of wastewater discharge and treatment facility upgrades on the environmental and biological conditions of Indian Creek, downstream from the Middle Basin wastewater treatment facility (WWTF). Streamflow, discrete and continuously measured stream-water chemistry, streambed-sediment chemistry, and habitat data will be used to: evaluate differences in...

Harmful Algal Blooms
You may notice a green, red or brown film on your favorite boating or swimming area in the summer. This coloring could mean that the water is affected by harmful algal blooms. Harmful algal blooms are an accumulation of tiny organisms known as algae and can release harmful toxins into the environment. Pictured here is Binder Lake in Iowa covered in algal blooms.
