Bacteria Growth, Persistence, and Source Assessment in Rural Texas Landscapes and Streams

Project Goals and Objectives: Building upon results from TSSWCB Project 07-06 and further focusing on addressing informational needs identified in the “Bacteria TMDL Task Force Report,” this project will focus on two primary tasks: 1) evaluating the predominant water quality parameters affecting instream bacterial fate and 2) evaluating and quantifying contributing E. coli loading to designated LU/LC types. These specific tasks were selected as those that will provide the most valuable information to watershed managers and practitioners who are faced with accurately predicting and planning to manage E. coli loading in Texas Watersheds. This will be supported by education and outreach efforts that deliver project results to personnel at local, regional, state and national levels.

Project Goals/Objectives: Based on routine water quality sampling of the stream, Geronimo Creek is impaired by elevated bacteria concentrations and has nutrient enrichment concerns and for nitrate-nitrogen as elevated for the 2008 Texas Water Quality Inventory. High bacteria concentrations do not support contact recreation use and high levels of nitrogen can cause excessive growth of aquatic vegetation leading to a decreased ablilty to support aquatic life use.

Development of a Watershed Protection Plan for the Concho River Basin

Project Goals/Objectives: This project provided an assessment of existing and potential water quality threats related to on-going nonpoint source (NPS) water pollution within the Concho River basin and will also provide a Watershed Protection Plan (WPP). Information obtained from this project was made available to state, federal, and local decision makers to promote the orderly restoration of the basin aquatic environment and to prevent additional degradation.

Efficient Nitrogen Fertilization: Accounting for Field Nitrogen Mineralization

Project Goals/Objectives: This project will demonstrate an enhanced soil test methodology that accounts for all sources of plant available N in the soil, including NO3-N, available NH4-N, and mineralizable N. These soil N sources provide N to crops and represent N that is not adequately accounted for by producers. The project will demonstrate the potential for reduced N runoff due to reduced N application based on this soil test methodology by establishing demonstration sites on research facilities and on private land.

Environmental Effects of In-House Windrow Composting of Poultry Litter

Project Goals/Objectives: This project will demonstrate the environmental effects of treating poultry litter using In-House Windrow Composting (IWC). The effect of IWC-treated litter on runoff water quality when the litter is land applied will be assessed as well as other benefits of this practice. Data is needed to evaluate parameters such as nutrient load and solubility and E. coli content in runoff water from land upon which IWC-treated poultry litter has been applied. It is anticipated that the IWC procedure should eliminate most E.
