Nutrient pollution, one of our most widespread, costly and challenging environmental problems, is caused by excess nitrogen and phosphorus in water.
Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. This growth causes major environmental damage as well as serious health problems in people and animals.
Nutrient pollution and resulting algal blooms cost billions, hurting industries and sectors that depend on clean water. Federal, state and local governments spend billions of dollars per year to combat nutrient pollution or prevent its effects.
The Nutrient Sensor Action Challenge builds upon the 2014 Nutrient Sensor Challenge, which helped develop affordable, high-performing, continuous nutrient sensors and analyzers. The 2017 challenge calls for demonstrations showing:
1) the effective use of low-cost continuous sensors, 2) innovative partnerships to pilot the sensors and manage data, and 3) how collected information can be used in state and local decision-making
By building successful strategies for incorporating nutrient sensors into existing water monitoring efforts, the Challenge can help states and local communities overcome barriers to preventing and reducing nutrient pollution.
Stage 1 - closes September 20, 2017
In Stage 1, teams will submit action plans describing an approach for sensor deployment and use, and how they will meet challenge goals.
The plans will be judged and up to 5 winning applications will be selected. The top entries will be awarded cash prizes totaling $50,000 and invited to participate in Stage II.
Stage II - Spring 2018
In Stage II of the Challenge, teams will deploy the sensors and collect data as they compete for a share in $100,000 in prizes.
The Nutrient Sensors Action Challenge is open to communities and organizations interested in deploying 2 or more low-cost (less than $15k) continuous nutrient sensors to address an important water quality problem. Teams should be currently engaged in water quality monitoring and have some level of experience and as well as sophistication with data management, and communication. This challenge is open to communities and organizations in the United States.

U.S. Environmental Protection Agency (EPA) U.S. Geological Survey (USGS) NOAA-directed U.S. Integrated Ocean Observing System (IOOS) Alliance for Coastal Technologies (ACT) U.S. Department of Agriculture (USDA) National Institute of Science and Technology (NIST)
The League of Women Voters of Jo Daviess County in Illinois (LWV-JDC) has been actively seeking water quality data in order to increase local knowledge. The ultimate goal is to achieve science-based stewardship of local water resources. This project proposes that two sensors be deployed, one each at the top and bottom of the Lower Galena River subwatershed to gather continuous data on nitrate levels in this portion of the Galena River. The League has been building relationships throughout the area for over six years and those relationships will provide valuable avenues for communicating the results of the data obtained through continuous nitrate monitoring. These data will be used as a basis for shifting landowners to best management practices designed to reduce nutrient pollution.
Development of a Real-time, Continuous Nutrient Monitoring Network for Western Lake Erie to Address Management of HABs and Hypoxia
Team Lead: Thomas Johengen, Cooperative Institute for Great Lakes Research (CIGLR), University of Michigan
Since the 1990s, Lake Erie has been experiencing increased water quality impairment, primarily in the form of extensive toxic cyanobacterial blooms. To combat the growing impacts on the ecosystem health and services of these tremendous natural resources, the Governments of Canada and the United States developed revised binational phosphorus reduction targets for Lake Erie with a goal of 40% lower loading rates then established under the 2012 Great Lakes Water Quality Agreement (GLWQA). To determine progress toward meeting nutrient reduction targets and verifying the response in the lake, active surveillance of nutrients in the lake is essential. Phosphorus concentrations in Lake Erie are highly variable in time and space, making it difficult to determine long-term trends. Deployment of continuous monitoring sensors to provide nearly continuous data will be a critical component of successful nutrient management.
High Frequency Nitrogen Sensors in Portland, Maine
Monitoring the Effects of Storms and Conowingo Dam Inputs on Nutrients in the Upper Chesapeake Bay
Lora Harris (Team Lead) & Jeremy Testa, University of Maryland Center for Environmental Science
Mike Trice, Maryland Department of Natural Resources
The Chesapeake Bay estuary has a long history of degraded water quality associated with elevated inputs of nitrogen (N), phosphorus (P), and sediments from its large watershed that spans six states and the District of Columbia. The Conowingo Dam, which is located in the lower Susquehanna River - the Bay's largest source of nutrients and freshwater - is decreasingly effective at holding back silt from entering the Upper Chesapeake Bay. As a result, additional nutrients associated with those silts are entering Chesapeake Bay and nutrient and sediment reduction strategies are being developed to address the increased nutrient load. The impact of these "new" nutrient inputs to Chesapeake Bay, however, remains poorly understood. This project would place two sensors in the Upper Chesapeake Bay and provide much data on how the nutrient load changes over time and in response to storm events. This can help validate models and give insight into the effect these nutrients will have on phytoplankton production and associated oxygen depletion in the estuary.
Quantifying the impact of dam removals on nitrate retention using low cost nitrate sensors
Team Lead: Dr.Wilfred Wollheim, Department of Natural Resources and Environment, University of New Hampshire
Current understanding of how reservoirs affect nitrogen moving through river systems is based on a small number of studies in larger reservoirs. These studies also looked at annual estimates rather than evaluating how nutrient retention varied through time. Dams and their reservoirs are increasingly being removed from the landscape, often because they are aging and would need costly repairs, have no significant utility and/or to improve anadromous fish passage and connectivity with spawning areas. Because reservoirs created by dams are potentially effective at removing nitrogen, such dam removals come with tradeoffs, including reduced nitrate removal. We propose to deploy sensors upstream and downstream of several reservoirs in coastal New England to quantify nitrate removal across seasons and storm events. We will also take advantage of ongoing dam removals and management activities to quantify the nitrogen removal by reservoirs.
