Nutrient Delivery to the Mississippi River from Kentucky
Scientists will be collecting field water-quality parameters and samples for laboratory analysis of nutrients, silica, and suspended sediment at the USGS Ohio River at Ironton, OH gaging station and the Green River at Spottsville, KY gaging station on a monthly basis. Stable isotope water samples also will be collected at the Green River site. The Ohio River at Ironton, OH site will serve, along...
Kankakee River at Davis, IN Mega Gage: Monitoring Groundwater/Surface-Water Interactions
What is the groundwater contribution to nitrates in surface water? That's the question we are trying to answer by looking at surface-water and groundwater interaction and the role each play in the movement of nitrates. We have added additional monitoring equipment to the USGS super gage Kankakee River at Davis, IN , which will allow us to calculate the nitrate load in groundwater using flow...
