1 From Coal Country to the Chesapeake: USGS Water Science in West Virginia and Virginia John Jastram

2 USGS Virginia & West Virginia Water Science Center What we do Operate streamgages, observation wells, and water-quality monitoring stations to provide reliable scientific information needed to make informed management decisions. Conduct interpretive investigations of specific water-resources problems. Most work is jointly funded by other Federal, State, and Local agencies.

8 Abandoned Underground-Coal-Mine Aquifers Compile available water-quality data from abandoned underground-coal-mine aquifers (AUCMA) Provide a reconnaissance tool to aid in development of AUCMA water resources for public supply, agriculture and industrial use Location of Underground Coal Mines in West Virginia

9 Abandoned Underground-Coal-Mine Aquifers Data collected from 1973 through sites Wells and AUCMA discharges 770 water quality samples USGS Data Series and Data Release anticipated publication Oct Sample Locations for Abandoned Underground-Coal-Mine Aquifers

11 West Virginia Borehole Geophysics Currently in 4 th year of data collection 60 wells logged across the state 40 more wells planned for a total of 100 Data at USGS GeoLog Locator

12 Load & Trend Estimation in the Chesapeake Bay Nontidal Network Chesapeake Bay Nontidal Monitoring Network Non-tidal network monitoring location Nutrient & sediment concentrations are measured during monthly and targeted high-flow sampling events. Goals: Quantify loads of nutrients and sediment in the nontidal rivers of the Chesapeake Bay watershed Estimate trends in loads to detect effects of changes in land management effects on water quality Daily Load = Daily Concentration * Mean Daily Discharge 2,340 annual samples!

14 Water-Quality Monitoring in the USDA & USGS Showcase Watersheds 2009 Executive Order tasked the USDA and USGS to partner in the Showcase Watersheds to describe the linkage between the implementation of conservation practices and water-quality improvements. Water-quality is assessed by continuous monitors and by the collection of samples from streams throughout each watershed.

15 Objectives completed in the initial phase of the study: To characterize current water-quality conditions. To identify the dominant sources, sinks, and transport process of nitrogen and, to a lesser extent, phosphorus. To quantify the implementation of conservation practices Underway: To transfer the knowledge gained in these basins to the rest of the Chesapeake Bay watershed Within 3-5 Years: To directly link trends in water quality to conservation practices U.S. Department of the Interior U.S. Geological Survey Report available online publication/sir Hyer and others,

16 Urbans Streams & Stormwater What are the nutrient and sediment loads in the urbanized Piedmont? Coastal Plain? Valley and Ridge? How do these loads compare to other urbanized areas? How do they compare to other watersheds in the region? How do monitored loads compare to modeled loads? What effect are management actions having on small urban/suburban watersheds?

17 Urbans Streams & SSC (mg/l) Stormwater Approach: Intensive Monitoring Continuous Monitoring Streamflow Water Quality (temperature, turbidity, SC, ph, DO) High Frequency Sampling Autosamplers Nutrient and Sediment Analyses Surrogate Methods for Load Computation Using continuous WQ data (ie. Turbidity) to compute loads (ie. Sediment) R 2 = Turbidity (FNU) +
