Non Technical Summary
Agricultural production is heavily dependent on water resources. Water resource quality and quantity are also greatly affected by agricultural practices at all scales. An excess or lack of water can detrimentally affect both economic productivity and yield productivity. Producers have turned to agricultural tile drainage to reduce excessive soil moisture, which has caused changes in the hydrology of these areas (e.g. Sheler, 2013). This practice has led to both increased (e.g. higher nitrate concentrations) and decreased (e.g. reduced sediment loadings) water resource risks. On the other hand, water availability in areas of inadequate precipitation is essential and a lack of water availability increases risks associated with agriculture (e.g. food security) as well as water resources (e.g. domestic water supplies Physical factors within the environment can impact the risk of management practices on water resources. Erosion and therefore sediment loads to waterbodies, for instance, are influenced by shear stress from water flow, soil type, etc. Evaluating the impact of these physical factors on water risk will improve the ability to assess local risks and scale-up appropriately to assess watershed risks.Risk AnalysisThe proposed project will incorporate analyses of physical factors contributing to water resource risks, management practices to reduce water resource risks, and evaluation of risks to and from agricultural systems as a whole. A major focus area of risk analysis will be assessing the impact of physical factors (e.g. soil type, shear stress, attachment rates, etc.) from agricultural systems on risks to waterbodies such as streams, rivers, and lakes. Nearly 60% of South Dakota's assessed rivers and streams are impaired and another 10% are threatened with impairment (EPA, 2015). The primary causes for impairments are pathogen indicators, includingE. coliand fecal coliform, and total suspended solids (TSS). Livestock, wildlife, and crop production were determined to be the most probable sources of impairment in South Dakota. Some physical factors such as soil type and organic matter can affectE. colisurvivability in environmental systems while others such as attachment rates and shear stress can affect the transport ofE. coli. Both survivability and transport contribute to high concentrations in water systems, which can pose a risk to human health. Risk ManagementFrom existing data and the aforementioned assessments, evaluations of management practices and systems risk will be performed. Agricultural management practices used to improve water quality include controlled drainage, saturated buffers, and seasonal riparian buffers. These management practices will be assessed for their ability to reduce pollutant transport and thus risk to waterbodies.As precipitation patterns change, managing water resources becomes more important. Water resource management will be examined to understand and mitigate risk associated with excessive and insufficient moisture conditions that may result from these changing precipitation patterns as well as natural climate variability.Benefits of proposed workUnderstanding the mechanisms for nutrient and bacterial transport will help determine effective management practices for reducing risks to waterbodies related to pollutant loadings. If these management practices are adopted, they can lead to improved water quality in South Dakota.Holistic systems analyses can improve natural resource use efficiencies, therefore improving water resource management. Better management of water resources during agricultural production can lead to higher productivity per volume of water used.?

Goals / Objectives
Examine the fate and transport of agricultural pollutants to provide support for water risk evaluations.Assess land use/land management impacts on water quality and quantity to evaluate impact on water risk.Evaluate and/or develop risk management strategies to aid in decision making related to water resources.
Project Methods
Field and laboratory studies will be conducted to assess the impact of physical factors on water risks. Both automated ISCO samplers and grab samples will be collected for analysis. Fecal indicator bacteria (FIB) studies will utilize the standard method for membrane filtration to enumerate bacteria which includes processing within 24 hours of sampling. Several processing stations will be set-up and used to complete sample processing within the limited time frame. Bacteria will be separated from particles via a combination of chemical (e.g. Tween 85) and physical (e.g. shaking) methods as proposed by Soupir et al. (2008). Pollution of nutrients from agricultural production to waterbodies will be sent to an outside lab for analysis or by scheduling time on an AQ2 Discrete Analyzer.Currently, no standard method exists for bacterial sediment sampling and processing. Therefore, a standard procedure will be developed as a part of this project. The method will be developed using a combination of literature review to examine previously applied methods and field studies to examine temporal variability, variability within a sample, and variability between sample locations. Once this procedure is developed, it will be used in the remainder of the study.Modeling studies will also be conducted to examine water quality and quantity risks including the impact of management practices and physical factors. Data required for model set-up will be accessed from existing sources as well as from field sampling. Some existing sources which will be utilized for water resource modeling include USGS gauging stations (flow), STORET (water quality monitoring data), USGS National Map Viewer (elevation, land cover, hydrography), and USDA NASS (crop yields).In some cases, existing models will not have adequate prediction capabilities (e.g. bacterial fate and transport); therefore, models may be developed to address questions associated with water resource risks. Developing a model often requires a combination of known relationships and field data to determine new relationships between parameters and/or validation of the model. For example, FIB fate and transport is dependent upon the persistence and movement of the bacteria. Persistence (i.e. growth/die-off) is affected by many parameters and is not wholly understood. Therefore, combining existing knowledge of bacterial persistence in the environment and newly acquired data will be required to improve the predictive capabilities of FIB fate and transport modeling.

A minimum of two peer-reviewed publications from this work are planned during the next reporting year. Objective 2: Assess land use/land management impacts on water quality and quantity to evaluate impact on water risk. (75% complete). Work will continue on the evaluation of bioreactors, drainage water management, and saturated buffers. A minimum of two publications are expected from this work during the next reporting year including a review of the resuspension of fecal indicator bacteria from stream bottom sediments and a preliminary study assessing the impact of bioreactors on E. coli and antibiotic-resistant bacteria concentrations . Objective 3: Evaluate and/or develop risk management strategies to aid in decision making related to water resources One research project is underway examining the impact of drainage water management using the SWAT hydrologic model.

    Impacts
    What was accomplished under these goals? The PI is working on several projects funded by this Hatch project and other externally funded grants. These projects address one or more of the concerns listed below: E. coli attachment and transport during high flows E. coli in streambed sediments Conservation drainage practices to remove nitrate from tile drainage Impact of bioreactors on E. coli and antibiotic-resistant bacterial transport in agricultural tile drainage Winter manure application impacts on water quality Algal bloom occurrence in South Dakota plains lakes Objective 1: Examine the fate and transport of agricultural pollutants to provide support for water risk evaluations (75% complete). The fate and transport of several agricultural pollutants are being examined through this project including E. coli, antibiotic resistant bacteria, phosphorus, and nitrate. Water and sediment samples have been collected at four sites along Skunk Creek, a tributary to the Big Sioux River located in eastern South Dakota. All four sites had 25 sediment samples collected to evaluate sediments as a potential source of E. coli to the water column. One site was evaluated for E. coli concentrations and attachment within the water column during eight storm events. Preliminary work indicates that sediments in South Dakota streams may be a reservoir for E. coli, and that roughly 75% of E. coli cells are transported in a buoyant state, thus contributing to water quality impairments for a longer time. Additional work has led to the determination that bacterial concentrations in sediment are highly variable and have a skewed distribution, with pockets of much higher bacteria concentrations. E. coli levels at each site are significantly correlated with sediment particle size; however, the direction of correlation is not consistent. Other factors that may influence E. coli concentration in sediments are carbon (currently being examined), microbial community, and nutrient availability. This will lead to recommendations on sediment sampling such as number of samples, sample collection considerations and sample processing methods (e.g. dilution rates, dilution solution, etc.). In addition, bacteria concentrations in sediments can remain high even after cattle have been removed from a stretch of stream, indicating that these bacteria can contribute to water quality impairments years after the initial source has been removed. Objective 2: Assess land use/land management impacts on water quality and quantity to evaluate impact on water risk. (75% complete). The PI has begun work on multiple projects examining the impact of land management practices on water quality, specifically E. coli and nitrate, and/or water quantity. The management practices being assessed include riparian area management, saturated buffer strips, drainage water management, and bioreactors. Field-scale management practices have been implemented across the eastern South Dakota. In addition, lab scale bioreactors were built to allow for control over system dynamics such as material, flow, and microbial community in the inflow water. Preliminary data shows promise for the ability for saturated buffers and drainage water management to reduce nitrate in drainage water. Saturated buffers removed between 55% and 98% of the nitrate within the tile drainage system. While drainage water management demonstrated the ability to reduce nitrate loads from tile drainage water, it was less successful than saturated buffers with removal rates ranging from 25% to 40%. In addition, sampling from bioreactors has shown that E. coli concentrations can either increase or decrease over time through the system. More work needs to be done to determine how bioreactors influence the concentrations of the bacteria through tile drained areas including what causes the growth versus decay. Seasonal Riparian Area Management (SRAM) systems are also being evaluated for their impact on microbial water quality and currently show promise to significantly reduce E. coli concentrations. SRAM is a modified Riparian Area Management system that removes cattle during the recreation season, but still allows haying twice per year which provides some profitability from the land while still providing conservation benefits. Objective 3: Evaluate and/or develop risk management strategies to aid in decision making related to water resources (65% complete). Several of the management practices being evaluated through this project help producers manage water quality risks, including the risk of bioreactors to contribute to elevated E. coli concentrations and the transfer of antibiotic resistance traits. SRAM systems are also being evaluated for their impact on water quality (i.e., microbial levels) and currently show promise to significantly reduce E. coli concentrations, thus reducing the risk of elevated microbial concentrations due to cattle access to streams.

    What was accomplished under these goals? The PI is working on several projects funded by this Hatch project and other externally funded grants. These projects address one or more of the goals for this Hatch project and include the following: E. coli attachment and transport during high flows E. coli in streambed sediments Conservation drainage practices to remove nitrate from tile drainage Impact of bioreactors on E. coli and antibiotic-resistant bacterial transport in agricultural tile drainage E. coli, antibiotic-resistant bacteria, and metal-tolerant bacteria accumulation in wetland environments Impact of precipitation resolution on modeling crop yields Winter manure application impacts on water quality Goal 1: Examine the fate and transport of agricultural pollutants to provide support for water risk evaluations (65% complete). The fate and transport of several agricultural pollutants are being examined through this project including E. coli, antibiotic resistant bacteria, metal tolerant bacteria, and nitrate. Preliminary work indicates that sediments in South Dakota streams may be a reservoir for E. coli and that roughly 75% of E. coli is transported in a buoyant state, allowing it to contribute to water quality impairments for a longer time. Additional work has led to the determination that sediment bacteria concentrations are highly variable and have a skewed distribution, with pockets of much higher bacteria concentrations. This will lead to recommendations on sediment sampling. Goal 2: Examine the fate and transport of agricultural pollutants to provide support for water risk evaluations (70% complete). The PI has begun work on multiple projects examining the impact of land management practices on water quality, specifically E. coli and nitrate, and/or water quantity. The management practices being assessed include riparian area management, saturated buffer strips, drainage water management, and bioreactors. Preliminary data shows promise for the ability for saturated buffers and drainage water management to reduce nitrate in drainage water. In addition, sampling from bioreactors has shown to both increase and decrease concentrations of E. coli through the systems, indicating more work needs to be done to determine how bioreactors influence the concentrations of the bacteria through tile drained areas including what causes the growth versus decay. Seasonal Riparian Area Management (SRAM) systems are also being evaluated for their impact on microbial water quality and currently show promise to significantly reduce E. coli concentrations. Goal 3: Evaluate and/or develop risk management strategies to aid in decision making related to water resources (55% complete). Three publications were accepted related to crop and location specific drought monitoring. In addition, several of the management practices being evaluated through this project help producers manage water quality risks, including the risk of bioreactors to contribute to elevated E. coli concentrations and the transfer of antibiotic resistance traits. SRAM systems are also being evaluated for their impact on microbial water quality and currently show promise to significantly reduce E. coli concentrations, thus reducing the risk of elevated microbial concentrations due to cattle access to streams.

How have the results been disseminated to communities of interest?This project began recently, and therefore, few results have been generated. The PI has presented to the research community once during this reporting period (UCOWR/NIWR Annual Water Resources Conference). Work relating to this project was also published in the Argus Leader, a regional newspaper. In addition, the PI attended the Ag. Ph.D. Field Day and demonstrated conservation practices, including bioreactors, drainage water management, and saturated buffers, to agricultural producers. What do you plan to do during the next reporting period to accomplish the goals?Several research projects are underway and will continue through the next reporting period, including: E. coli attachment and transport during high flows E. coli in streambed sediments Conservation drainage practices to remove nitrate from tile drainage Impact of bioreactors on E. coli and antibiotic-resistant bacterial transport in agricultural tile drainage E. coli, antibiotic-resistant bacteria, and metal-tolerant bacteria accumulation in wetland environments Impact of precipitation resolution on modeling crop yields Goal 1:Examine the fate and transport of agricultural pollutants to provide support for water risk evaluations. We will complete the evaluation of the spatial variation of E. coli in streambed sediments and will continue to evaluate the temporal variation and stability of E. coli concentrations in streambed sediments. A minimum of one peer-reviewed publication from this work is planned during the next fiscal year. Goal 2: Assess land use/land management impacts on water quality and quantity to evaluate impact on water risk Work will continue on the evaluation of bioreactors, drainage water management, and saturated buffers. A minimum of two publications are expected from this work during the next fiscal year including a review of the impact of management practices on E. coli concentrations and a preliminary study assessing the impact of bioreactors on E. coli and antibiotic-resistant bacteria concentrations . Goal 3: ?Evaluate and/or develop risk management strategies to aid in decision making related to water resources. Three publications are in review in Transactions of the ASABE. One research project is underway examining the impact of different precipitation data sets on modeled hydrologic conditions and crop growth using the SWAT hydrologic model.

    Impacts
    What was accomplished under these goals? The PI is working on several projects funded by this Hatch project and other externally funded grants. These projects address one or more of the goals for this Hatch project and include the following: E. coli attachment and transport during high flows E. coli in streambed sediments Conservation drainage practices to remove nitrate from tile drainage Impact of bioreactors on E. coli and antibiotic-resistant bacterial transport in agricultural tile drainage E. coli, antibiotic-resistant bacteria, and metal-tolerant bacteria accumulation in wetland environments Impact of precipitation resolution on modeling crop yields Goal 1: Examine the fate and transport of agricultural pollutants to provide support for water risk evaluations (15% complete). The fate and transport of several agricultural pollutants are being examined through this project including E. coli, antibiotic resistant bacteria, metal tolerant bacteria, and nitrate. Preliminary work indicates that sediments in South Dakota streams may be a reservoir for E. coli and that roughly 75% of E. coli is transported in a buoyant state, allowing it to contribute to water quality impairments for a longer time. Goal 2: Examine the fate and transport of agricultural pollutants to provide support for water risk evaluations (20% complete). The PI has begun work on multiple projects examining the impact of land management practices on water quality, specifically E. coli and nitrate, and/or water quantity. The management practices being assessed include riparian area management, saturated buffer strips, drainage water management, and bioreactors. Preliminary data shows promise for the ability for saturated buffers and drainage water management to reduce nitrate in drainage water. Goal 3: Evaluate and/or develop risk management strategies to aid in decision making related to water resources (15% complete). Three publications were submitted and are in review related to crop and location specific drought monitoring. In addition, several of the management practices being evaluated through this project help producers manage water quality risks. By reducing nitrates and bacteria, the downstream risk of these pollutants is reduced.Preliminary data shows promise for the ability for saturated buffers and drainage water management to reduce nitrate in drainage water. Preliminary work on bioreactors demonstrates thatE. coliconcentrations can remain constant, but also have the potential to grow in this carbon rich environment.
