Although ground water discharge‐can limit plume migration and transfer contaminants to streams, interactions among ground water, rivers, and tributaries in contaminated watersheds have received relatively little attention. We used multiple methods to delineate seepage along Little Bayou and Bayou Creeks, tributaries to the Ohio River in McCracken County, Kentucky, from July 1996 through July 1998. The Paducah Gaseous Diffusion Plant (PGDP) lies between the creeks. Trichloroethene (TCE) and technetium‐99 plumes within the underlying Regional Gravel Aquifer (RGA) extend several kilometers from PGDP toward the river. Both creeks tend to gain flow where they are incised into the RGA or contiguous strata in the Ohio flood plain. Bayou Creek also gains flow upstream of PGDP; other reaches of both creeks tend to lose flow. Local storms, river floods, and seasonal dry periods caused temporary changes in seepage rates and reversals in hydraulic gradients. Gaining conditions were indicated by seeps, springs, and boils, by upward hydraulic gradients from bank wells and bed piezometers to the stream, and by mixing models using chloride and oxygen‐18. Mixing models and downward hydraulic gradients from the stream to wells indicated losing conditions. Annual ranges of stream, bed, and bank temperatures tended to be narrower, bed and bank temperatures in summer and early autumn tended to be cooler, and maximum values of specific discharge measured by seepage meters were greater along gaining than along losing reaches. Estimates of specific discharge from stream gauging and one‐dimensional flow‐modeling did not conclusively identify losing and gaining reaches, but absolute values of those estimates fell within the range of seepage‐meter measurements. Contaminants discharging to Little Bayou Creek were diluted downstream by uncontaminated ground water. Volatilization, biodegradation, or sorption probably removed TCE from stream water. These results indicate that discharge to tributaries can limit seepage of contaminants to rivers.

Land subsidence, caused by longwall mining, has a negative effect on overlying watersheds. Nine streams were monitored from their headwaters to their mouths for discharge, temperature, conductivity, alluvium thickness, and alluvium sediment size. Seven streams are located over undermined longwall panels, with two located over non-undermined areas. Discharge data shows that non-undermined watersheds do not experience stream dewatering, regardless of alluvium thickness or sediment size. Streams located over active or recently mined longwall panels experience water loss that ranges from slight to total. Impacted streams with overall increases in conductivity and decreases in water temperature suggest that lost streamflow travels as underflow, mixing with more conductive, cooler ground water. A thin alluvial cover and poor sorting of streambed sediments appear to prolong stream dewatering. The excavation of stream channels did not remedy dewatering impacts, but returns a positive drainage gradient to the stream channel. iii ACKNOWLEDGEMENTS My deepest thanks and gratitude are extended to all who have made this project possible. I would especially like to thank Dr. Henry Rauch for the countless hours spent in his office and for the guidance and tutelage that he has shown throughout the entire project; Dr. Steve Kite for his help, suggestions and support; Dr. John Renton for his time and suggestions; and Mr. Ron Evaldi for his technical suggestions and time. I would also like to thank Mine Z coal company personnel for their help, suggestions, time, and partial funding for this project. Thanks is extended to the construction company that manufactured the weirs used in this project and also to the private land owners who supplied me with information, stories, and permission to "walk around in their creek". Dr. Shumaker provided me with some well needed funding for this project, and for that I am grateful. Last but not least, I want to thank my family and friends for their constant encouragement and support. Special thanks are given to my parents, Donald and Barbara, and brother, Mike. I also had free help with my fieldwork from my friends, Peter Fahringer and Tanner Sattler, and my fiancée, Kelly. If it weren't for their help, I would probably still be conducting field work. iv

Focused groundwater discharge to streams is problematic at contaminated sites because high fluxes can limit natural attenuation in the hyporheic zone. However, information on location, spatial evolution, and temporal persistence of springs in unlithified sediments over multiyear time scales is limited. We examine discharge at point (~1‐m) to reach (~300‐m) scales along a stream that intercepts trichloroethene and technetium‐99 plumes from a Superfund site. During 2011 to 2012, we seasonally monitored stream and spring flow and contaminant concentrations, along with probing streambed temperatures on a grid in winter and summer, building on prior monitoring during 1999 to 2002. Baseflow measured by both gauging and dye dilution generally increased with distance downstream, and stream and spring discharge varied seasonally, from minima in October to January to maxima in February to June. Thermal anomalies identified by probing occupied approximately 3% to 6% of the reach and typically coincided with visible springs or seeps. Locations of anomalies were similar to those identified in summer 2002, although some orifices disappeared and others emerged. Vertical groundwater fluxes calculated from probing tended to be less than net fluxes calculated from stream discharge, perhaps in part because the assumption of one‐dimensional, steady‐state flow in calculating point fluxes was simplistic. Maximum contaminant concentrations and fluxes decreased between 1999 to 2001 and 2011 to 2012 as a result of partial capture by an upgradient pump‐and‐treat system. Our findings confirm that springs in unlithified sediments can remain stationary within a few meters over decadal time scales, and seasonal variability in discharge can be greater than decadal variability.
